True to its name and its reputation as a mission that overcomes challenges, Perseverance and its team of scientists and engineers turned trials to triumphs in yet another outstanding year for the mission. There’s a lot to celebrate about Perseverance’s past year on Mars, but here are three of my top mission moments this year, in the order in which they happened. 1. SHERLOC’s cover opens NASA’s Mars Perseverance rover captured this image of its SHERLOC instrument (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals), showing the cover mechanism of SHERLOC’s Autofocus and Context Imager camera (ACI) in a nearly open configuration. The rover acquired this image using its Left Mastcam-Z camera — one of a pair of cameras located high on the rover’s mast — on March 3, 2024 (sol 1079, or Martian day 1,079 of the Mars 2020 mission), at the local mean solar time of 12:18:41. NASA/JPL-Caltech/ASU In early January the SHERLOC instrument’s cover mechanism stopped responding during a routine attempt to acquire data on a rock outcrop in the Margin unit. After six weeks of team diagnostics, the SHERLOC instrument was declared offline and many of us feared that the instrument had met its end. In early March, the team made significant progress in driving the cover to a more open position. Then, to everyone’s surprise, the SHERLOC cover moved unexpectedly to a nearly completely open position during a movement of the arm on sol 1077. I remember staring in wonder at the image of the cover (taken on sol 1079), feeling real optimism for the first time that SHERLOC could be recovered. The team spent the next few months developing a new plan for operating SHERLOC with its cover open, and the instrument was declared back online at the end of June. 2. A potential biosignature at Cheyava Falls NASA’s Perseverance Mars rover captured this image of “leopard spots” on a rock nicknamed “Cheyava Falls” on July 18, 2024 — sol 1212. or the 1,212th Martian day of the mission. Running the length of the rock are large white calcium sulfate veins. Between those veins are bands of material whose reddish color suggests the presence of hematite, one of the minerals that gives Mars its distinctive rusty hue. Scientists are particularly interested in the millimeter-size, irregularly shaped light patches on the central reddish band (from lower left to upper right of the image) that resemble leopard spots. Perseverance captured the image using a camera called WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), part of the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument suite located on the end of Perseverance’s robotic arm. NASA/JPL-Caltech/MSSS No top list would be complete without Perseverance’s discovery in July 2024 of a potential biosignature in the form of sub-millimeter-scale “leopard spots” at an outcrop called Cheyava Falls. These features, which formed during chemical reactions within the rock, have dark rims and light cores and occur together with organic carbon. On Earth, these chemical reactions are often driven by or associated with microbes. Although we can’t say for sure that microbes were involved in the formation of the leopard spots at Cheyava Falls, this question can be answered when Perseverance’s samples are returned to Earth. In the meantime, this rock remains one of the most compelling rocks discovered on Mars. 3. Arrival at Witch Hazel Hill NASA’s Mars Perseverance rover acquired this image at the top of Witch Hazel Hill, of the South Arm and Minnie Hill outcrops. Perseverance used its Left Navigation Camera (Navcam) — which also aids in driving — located high on the rover’s mast. The rover captured the image on Dec. 16, 2024 (sol 1359, or Martian day 1,359 of the Mars 2020 mission), at the local mean solar time of 13:26:38. NASA/JPL-Caltech Closing out 2024 on a high note, in mid-December Perseverance arrived at the top of a sequence of rock exposed on the western edge of the Jezero crater rim called Witch Hazel Hill. These rocks pre-date the formation of Jezero crater and could be amongst the oldest rocks exposed on the surface of Mars. These rocks have the potential to tell us about a period of solar system history not well-preserved on our own planet Earth, and they may record important clues about the early history and habitability of Mars. Witch Hazel Hill first caught my attention during landing site selection several years ago, when we were debating the merits of landing Perseverance in Jezero versus sites outside the crater. At the time, this area seemed just out of reach for a Jezero-focused mission, so I’m thrilled that the rover is now exploring this site! The Mars 2020 mission had its ups and downs and a fair share of surprises during 2024, but we are looking ahead to 2025 with excitement, as Perseverance continues to explore and sample the Jezero crater rim.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Radiation Tolerant Computer, or RadPC, payload undergoes final checkout at Montana State University in Bozeman, which leads the payload project. RadPC is one of 10 NASA payloads set to fly aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative in 2025. RadPC prototypes previously were tested aboard the International Space Station and Earth-orbiting satellites, but the technology demonstrator will undergo its biggest trial in transit to the Moon – passing through the Earth’s Van Allen radiation belts – and during its roughly two-week mission on the lunar surface. Photo courtesy Firefly Aerospace Onboard computers are critical to space exploration, aiding nearly every spacecraft function from propulsion and navigation systems to life support technology, science data retrieval and analysis, communications, and reentry. But computers in space are susceptible to ionizing solar and cosmic radiation. Just one high-energy particle can trigger a so-called “single event effect,” causing minor data errors that lead to cascading malfunctions, system crashes, and permanent damage. NASA has long sought cost-effective solutions to mitigate radiation effects on computers to ensure mission safety and success. Enter the Radiation Tolerant Computer (RadPC) technology demonstration, one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. RadPC will be carried to the Moon’s surface by Firefly Aerospace’s Blue Ghost 1 lunar lander. Developed by researchers at Montana State University in Bozeman, RadPC aims to demonstrate computer recovery from faults caused by single event effects of ionizing radiation. The computer is designed to gauge its own real-time state of health by employing redundant processors implemented on off-the-shelf integrated circuits called field programmable gate arrays. These tile-like logic blocks are capable of being easily replaced following a confirmed ionizing particle strike. In the event of a radiation strike, RadPC’s patented recovery procedures can identify the location of the fault and repair the issue in the background. As an added science benefit, RadPC carries three dosimeters to measure varying levels of radiation in the lunar environment with each tuned to different sensitivity levels. These dosimeters will continuously measure the interaction between Earth’s magnetosphere and the solar wind during its journey to the Moon. It will also provide detailed radiation information about Blue Ghost’s lunar landing site at Mare Crisium, which could help to safeguard future Artemis astronauts. “This is RadPC’s first mission out into the wild, so to speak,” said Dennis Harris, who manages the payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The RadPC CLPS payload is an exciting opportunity to verify a radiation-tolerant computer option that could make future Moon to Mars missions safer and more cost-effective.” Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights.

Supporting the International Space Station is an around-the-clock responsibility for NASA and its international partners. This means there is always a team of flight operations and payload personnel working with the orbiting laboratory’s crew – including overnight, on weekends, and during the holidays. At Johnson Space Center’s Mission Control Center (MCC) in Houston, flight directors organize fun activities to help these teams build camaraderie and celebrate holidays while they work, no matter the hour. “Working in mission control is a very rewarding job, but it also demands a lot from flight controllers and leads to time away from family,” said Fiona Antkowiak, a flight director in the MCC. “We really want to make the holiday shifts in MCC extra special.” Fiona Antkowiak (front right) and her Orbit 3 shift team members show off their holiday cookie creations in the Mission Control Center (MCC) at NASA’s Johnson Space Center in Houston. Image courtesy of Fiona Antkowiak Antkowiak recalled working Christmas 2018 as a space station flight controller. That year, teams participated in a friendly cookie-decorating competition, with the three different MCC shifts going head-to-head. When flight directors started brainstorming festive ideas for the 2024 holiday season, Antkowiak suggested reviving the contest and asked the Expedition 72 crew if they would be willing to judge the entries. “They agreed, and also told us they would decorate some cookies for us to judge, too!” Astronauts aboard the International Space Station often decorate cookies as part of their holiday celebrations and have become adept at manipulating icing in zero gravity. NASA astronaut Nick Hague shared on social media, “It opened up a whole new dimension, quite literally, with layer upon layer of icing.” The Expedition 72 crew decorates cookies aboard the International Space Station (left), and their finished products. NASA Teams in the MCC in Houston and NASA’s Marshall Space Flight Center Payload Operations Integration Center in Huntsville, Alabama, were joined by international partners ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency) from their respective control centers. The decorating began late on Christmas Eve and concluded on Christmas Day, ensuring space station crew members could participate in the fun on their days off. The 36 entries drew inspiration from traditional holiday imagery, human spaceflight, sports teams, and comic books. Each crew member selected their personal favorite cookie, in addition to choosing an overall winner. Payload Operations Director Jaclyn Poteraj created the winning cookie, depicting an astronaut riding on a reindeer made of cargo transfer bags, which are used to transport cargo to and store it aboard the International Space Station.

Inside of the Electrostatics and Surface Physics Laboratory at NASA’s Kennedy Space Center in Florida, an electrodynamic dust shield (EDS) is in view on Jan. 18, 2023. The dust shield is one of the payloads that will fly aboard Firefly Aerospace’s Blue Ghost lunar lander as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. NASA/Cory Huston Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use the Electrodynamic Dust Shield (EDS) technology. The EDS technology is headed to the Moon as part of the agency’s Artemis campaign. This innovative technology will be demonstrated on the lunar surface, where it will use electrical forces to lift and remove lunar regolith, or dirt, from various surfaces. This dust-mitigating technology is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida Wednesday, Jan. 15, with Firefly Aerospace’s Blue Ghost Lander. Using transparent electrodes and electric fields, EDS technology can lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the charged dust will be critical to the success of Moon missions under the agency’s CLPS initiative and Artemis campaign. “For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.” Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen. “Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler said. Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. EDS was funded by the Space Technology Mission Directorate (STMD) Game Changing Development Program (GCD). Learn more about. CLPS and Artemis at https://www.nasa.gov/clps. View the full article

On Jan. 7, 1610, Italian astronomer Galileo Galilei peered through his newly improved 20-power homemade telescope at the planet Jupiter. He noticed three other points of light near the planet, at first believing them to be distant stars. Observing them over several nights, he noted that they appeared to move in the wrong direction with regard to the background stars and they remained in Jupiter’s proximity but changed their positions relative to one another. Four days later, he observed a fourth point of light near the planet with the same unusual behavior. By Jan. 15, Galileo correctly concluded that he had discovered four moons orbiting around Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth. Two of Galileo’s telescopes.National Geographic. Painting by Giuseppe Bertini (1858) of Galileo demonstrating his telescope to the Doge of Venice.gabrielevanin.it Page from Galileo’s notebook about his observations of Jupiter’s satellites.University of Michigan Special Collections Library. In March 1610, Galileo published his discoveries of Jupiter’s satellites and other celestial observations in a book titled Siderius Nuncius (The Starry Messenger). As their discoverer, Galileo had naming rights to Jupiter’s satellites. He proposed to name them after his patrons the Medicis and astronomers called them the Medicean Stars through much of the seventeenth century, although in his own notes Galileo referred to them by the Roman numerals I, II, III, and IV, in order of their distance from Jupiter. Astronomers still refer to the four moons as the Galilean satellites in honor of their discoverer. In 1614, the German astronomer Johannes Kepler suggested naming the satellites after mythological figures associated with Jupiter, namely Io, Europa, Ganymede, and Callisto, but his idea didn’t catch on for more than 200 years. Scientists didn’t discover any more satellites around Jupiter until 1892 when American astronomer E.E. Barnard found Jupiter’s fifth moon Amalthea, much smaller than the Galilean moons and orbiting closer to the planet than Io. It was the last satellite in the solar system found by visual observation – all subsequent discoveries occurred via photography or digital imaging. As of today, astronomers have identified 95 moons orbiting Jupiter. Image of Jupiter and three of its four Galilean satellites through an amateur telescope, similar to what Galileo might have seen. Hubble Space Telescope image of Jupiter and three of its four Galilean satellites during a rare triple transit. Although each of the Galilean satellites has unique features, such as the volcanoes of Io, the heavily cratered surface of Callisto, and the magnetic field of Ganymede, scientists have focused more attention on Europa due to the tantalizing possibility that it might be hospitable to life. In the 1970s, NASA’s Pioneer 10 and 11 and Voyager 1 and 2 spacecraft took ever increasingly detailed images of the large satellites including Europa during their flybys of Jupiter. The photographs revealed Europa to have the smoothest surface of any object in the solar system, indicating a relatively young crust, and also one of the brightest of any satellite indicating a highly reflective surface. These features led scientists to hypothesize that Europa is covered by an icy crust floating on a subsurface salty ocean. They further postulated that tidal heating caused by Jupiter’s gravity reforms the surface ice layer in cycles of melting and freezing. Image of Europa taken by Pioneer 10 during its flyby of Jupiter in 1973. Image of Europa taken by Voyager 1 during its 1979 flyby of Jupiter. Image of Europa taken by Voyager 2 during its 1979 flyby of Jupiter. More detailed observations from NASA’s Galileo spacecraft that orbited Jupiter between 1995 and 2003 and completed 11 close encounters with Europa revealed that long linear features on its surface may indicate tidal or tectonic activity. Reddish-brown material along the fissures and in splotches elsewhere on the surface may contain salts and sulfur compounds transported from below the crust and modified by radiation. Observations from the Hubble Space Telescope and re-analysis of images from Galileo revealed possible plumes emanating from beneath Europa’s crust, lending credence to that hypothesis. While the exact composition of this material is not known, it likely holds clues to whether Europa may be hospitable to life. Global view of Europa from the Galileo spacecraft. More detailed views of varied terrain on Europa from Galileo. Cutaway illustration of Europa’s icy crust, subsurface ocean and possible vents that transport material to the surface. Future robotic explorers of Europa may answer some of the outstanding questions about this unique satellite of Jupiter. NASA’s Europa Clipper set off in October 2024 on a 5.5-year journey to Jupiter. After its arrival in 2030, the spacecraft will enter orbit around the giant planet and conduct 49 flybys of Europa during its four-year mission. Managed by the Jet Propulsion Laboratory in Pasadena, California, and the Applied Physics Laboratory at Johns Hopkins University in Baltimore, Maryland, Europa Clipper will carry nine instruments including imaging systems and a radar to better understand the structure of the icy crust. Data from Europa Clipper will complement information returned by the European Space Agency’s JUICE (Jupiter Icy Moon Explorer) spacecraft. Launched in April 2023, JUICE will first enter orbit around Jupiter in 2031 and then enter orbit around Ganymede in 2034. The spacecraft also plans to conduct studies of Europa complementary with Europa Clipper’s. The two spacecraft should greatly increase our understanding of Europa and perhaps uncover new mysteries.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Lunar Planet Vac, or LPV, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. LPV is designed to efficiently collect and transfer lunar soil from the surface to other science and analysis instruments on the Moon.Photo courtesy Firefly Aerospace Among all the challenges of voyaging to and successfully landing on other worlds, the effective collection and study of soil and rock samples cannot be underestimated. To quickly and thoroughly collect and analyze samples during next-generation Artemis Moon missions and future journeys to Mars and other planetary bodies, NASA seeks a paradigm shift in techniques that will more cost-effectively obtain samples, conduct in situ testing with or without astronaut oversight, and permit real-time sample data return to researchers on Earth. That’s the planned task of an innovative technology demonstration called Lunar PlanetVac (LPV), one of 10 NASA payloads flying aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. LPV will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander. Developed by Honeybee Robotics, a Blue Origin company of Altadena, California, LPV is a pneumatic, compressed gas-powered sample acquisition and delivery system – essentially, a vacuum cleaner that brings its own gas. It’s designed to efficiently collect and transfer lunar soil from the surface to other science instruments or sample return containers without reliance on gravity. Secured to the Blue Ghost lunar lander, LPV’s sampling head will use pressurized gas to stir up the lunar regolith, or soil, creating a small tornado. If successful, material from the dust cloud it creates then will be funneled into a transfer tube via the payload’s secondary pneumatic jets and collected in a sample container. The entire autonomous operation is expected to take just seconds and maintains planetary protection protocols. Collected regolith – including particles up to 1 cm in size, or roughly 0.4 inches – will be sieved and photographed inside the sample container with the findings transmitted back to Earth in real time. The innovative approach to sample collection and in situ testing could prove to be a game-changer, said Dennis Harris, who manages the LPV payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “There’s no digging, no mechanical arm to wear out requiring servicing or replacement – it functions like a vacuum cleaner,” Harris said. “The technology on this CLPS payload could benefit the search for water, helium, and other resources and provide a clearer picture of in situ materials available to NASA and its partners for fabricating lunar habitats and launch pads, expanding scientific knowledge and the practical exploration of the solar system every step of the way.” Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights.

4 min read Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing. NICER will be the first NASA observatory repaired on-orbit since the last servicing mission for the Hubble Space Telescope in 2009. Hague and other astronauts, including Don Pettit, who is also currently on the space station, rehearsed the NICER patch procedures in the NBL (Neutral Buoyancy Laboratory), a 6.2-million-gallon indoor pool at NASA’s Johnson Space Center in Houston, in 2024. NASA astronaut Nick Hague holds a patch for NICER (Neutron star Interior Composition Explorer) at the end of a T-handle tool during a training exercise on May 16, 2024, in the NBL (Neutral Buoyancy Laboratory) at NASA’s Johnson Space Center in Houston. NASA/NBL Dive Team Astronaut Nick Hague removes a patch from the caddy using a T-handle tool during a training exercise in the NBL at NASA Johnson on May 16, 2024. The booklet on his wrist has a schematic of the NICER telescope and where the patches will go.NASA/NBL Dive Team “We use the NBL to mimic, as much as possible, the conditions astronauts will experience while preforming a task during a spacewalk,” said Lucas Widner, a flight controller at KBR and NASA Johnson who ran the NICER NBL sessions. “Most projects outside the station focus on maintenance and upgrades to components like solar panels. It’s been exciting for all of us to be part of getting a science mission back to normal operations.” From its perch near the space station’s starboard solar array, NICER studies the X-ray sky, including erupting galaxies, black holes, superdense stellar remnants called neutron stars, and even comets in our solar system. But in May 2023, NICER developed a “light leak.” Sunlight began entering the telescope through several small, damaged areas in the telescope’s thin thermal shields. During the station’s daytime, the light reaches the X-ray detectors, saturating sensors and interfering with NICER’s measurements of cosmic objects. The mission team altered their daytime observing strategy to mitigate the effect. UAE (United Arab Emirates) astronaut Sultan Alneyadi captured this view of NICER from a window in the space station’s Poisk Mini-Research Module 2 in July 2023. Photos like this one helped the NICER team map the damage to the telescope’s thermal shields.NASA/Sultan Alneyadi Some of NICER’s damaged thermal shields (circled) are visible in this photograph.NASA/Sultan Alneyadi The team also developed a plan to cover the largest areas of damage using wedge-shaped patches. Hague will slide the patches into the telescope’s sunshades and lock them into place. “We designed the patches so they could be installed either robotically or by an astronaut,” said Steve Kenyon, NICER’s mechanical engineering lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “They’re installed using a tool called a T-handle that the astronauts are already familiar with.” The NBL contains life-size mockups of sections of the space station. Under the supervision of a swarm of scuba divers, a pair of astronauts rehearse exiting and returning through an airlock, traversing the outside of the station, and completing tasks. For the NICER repair, the NBL team created a full-scale model of NICER and its surroundings near the starboard solar array. Hague, Pettit, and other astronauts practiced taking the patches out of their caddy, inserting them into the sunshades, locking them into place, and verifying they were secure. The task took just under an hour each time, which included the time astronauts needed to travel to NICER, set up their tools, survey the telescope for previously undetected damage, complete the repair, and clean up their tools. Practice runs also provided opportunities for the astronauts to troubleshoot how to position themselves so they could reach NICER without touching it too often and for flight controllers to identify safety concerns around the repair. Astronaut Don Pettit simulates taking pictures of the NICER telescope mockup during a training exercise in the NBL at NASA Johnson on May 16, 2024.NASA/NBL Dive Team Astronaut Don Pettit removes a patch from the caddy during a training exercise in the NBL at NASA Johnson on May 16, 2024.NASA/NBL Dive Team Being fully submerged in a pool is not the same as being in space, of course, so some issues that arose were “pool-isms.” For example, astronauts sometimes drifted upward while preparing to install the patches in a way unlikely to happen in space. Members of the NICER team, including Kenyon and the mission’s principal investigator, Keith Gendreau at NASA Goddard, supported the NBL practice runs. They helped answer questions about the physical aspects of the telescope, as well as science questions from the astronauts and flight controllers. NICER is the leading source of science results on the space station. “It was awesome to watch the training sessions and be able to debrief with the astronauts afterward,” Gendreau said. “There isn’t usually a lot of crossover between astrophysics science missions and human spaceflight. NICER will be the first X-ray telescope serviced by astronauts. It’s been an exciting experience, and we’re all looking forward to the spacewalk where it will all come together.” The NICER telescope is an Astrophysics Mission of Opportunity within NASA’s Explorers Program, which provides frequent flight opportunities for world-class scientific investigations from space utilizing innovative, streamlined, and efficient management approaches within the heliophysics and astrophysics science areas. NASA’s Space Technology Mission Directorate supported the SEXTANT component of the mission, demonstrating pulsar-based spacecraft navigation.

Technicians have successfully integrated NASA’s Nancy Grace Roman Space Telescope’s payload – the telescope, instrument carrier, and two instruments – to the spacecraft that will deliver the observatory to its place in space and enable it to function while there. “With this incredible milestone, Roman remains on track for launch, and we’re a big step closer to unveiling the cosmos as never before,” said Mark Clampin, acting deputy associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “It’s been fantastic to watch the team’s progress throughout the integration phase. I look forward to Roman’s transformative observations.” Technicians recently integrated the payload – telescope, instrument carrier, and two instruments – for NASA’s Nancy Grace Roman Space Telescope in the big clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. NASA/Chris Gunn The newly joined space hardware will now undergo extensive testing. The first test will ensure each major element operates as designed when integrated with the rest of the observatory and establish the hardware’s combined performance. Then environmental tests will subject the payload to the electromagnetic, vibration, and thermal vacuum environments it will experience during launch and on-orbit operations. These tests will ensure the hardware and the launch vehicle will not interfere with each other when operating, verify the communications antennas won’t create electromagnetic interference with other observatory hardware, shake the assembly to make sure it will survive extreme vibration during launch, assess its performance across its expected range of operating temperatures, and make sure the instruments and mirrors are properly optically aligned. Meanwhile, Roman’s deployable aperture cover will be integrated with the outer barrel assembly, and then the solar panels will be added before spring. Then the structure will be joined to the payload and spacecraft this fall. The Roman mission remains on track for completion by fall 2026 and launch no later than May 2027.

City lights streak across Earth and an aurora is visible on the horizon as the International Space Station passes over Lake Michigan.NASA For more than 24 years, NASA has supported a continuous U.S. human presence aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth for the benefit of humanity. The space station is a springboard to NASA’s next great leaps in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars. Read more about the groundbreaking work conducted in 2024 aboard the station: Robot performs remote simulated surgery On long-duration missions, crew members may need surgical procedures, whether simple stitches or an emergency appendectomy. A small robot successfully performed simulated surgical procedures on the space station in early February 2024 for the Robotic Surgery Tech Demo, using two “hands” to grasp and cut rubber bands simulating tissue. Researchers compare the procedures conducted aboard the station and on Earth to evaluate the effects of microgravity and communication delays between space and ground. NASA astronaut Loral O’Hara holds the Robotic Surgery Tech Demo hardware on the International Space Station.NASA 3D metal print in space On May 30,2024, the ESA (European Space Agency) Metal 3D Printer investigation created a small stainless steel s-curve, the first metal 3D print in space. Crew members on future missions could print metal parts for equipment maintenance, eliminating the need to pack spare parts and tools at launch. This technology also has the potential to improve additive manufacturing on Earth. NASA astronaut Jeanette Epps prints samples for Metal 3D Printer on the International Space Station.NASA Here’s looking at you, Earth The space station orbits roughly 250 miles above and passes over 90 percent of Earth’s population, providing a unique perspective for photographing the planet. Astronauts have taken more than 5.3 million images of Earth to monitor the planet’s changing landscape. The Expedition 71 crew took over 630,000 images, well above the average of roughly 105,000 for a single mission. This year, images included the April solar eclipse and auroras produced as the Sun’s 11-year activity cycle peaks. Others supported response to over 14 disaster events including hurricanes. In addition, 80,000 images were geolocated using machine learning, improving public search capabilities. This astronaut photo from the International Space Station shows Hurricane Milton, a category 4 storm in the Gulf of Mexico, nearing the coast of Florida in October.NASA Miles of flawless fibers From mid-February to mid-March of 2024, the Flawless Space Fibers-1 system produced more than seven miles of optical fiber in space. One draw of more than a half mile of fiber surpassed the prior record of 82 feet for the longest fiber manufactured in space, demonstrating that commercial lengths of fiber can be produced in orbit. Fibers produced in microgravity can be superior to those produced in Earth’s gravity. These fibers are made from ZBLAN, a glass alloy with the potential to provide more than 10 times the transmission capacity of traditional silica-based fibers. NASA astronaut Loral O’Hara conducting Flawless Space Fibers operations in the Microgravity Science Glovebox inside the International Space Station.NASA Tell-tale heart In May 2024, BFF-Cardiac successfully bioprinted a three-dimensional human heart tissue sample using the Redwire BioFabrication Facility. Tissues bioprinted in the microgravity of the space station hold their shape without the use of artificial scaffolds. These bioprinted human heart tissues eventually could be used to create personalized patches for tissue damaged by events such as heart attacks. The tissue sample is undergoing further testing on Earth. At left, NASA astronaut Matthew Dominick works on the BFF-Cardiac investigation aboard the International Space Station. At right, cardiac tissue is 3D bioprinted for the investigation.NASA Station-tested radiation technology flown on Artemis I The Orion spacecraft carried 5,600 passive and 34 active radiation detectors on its Artemis I uncrewed mission around the Moon in November 2022. Some of these devices previously were tested on the space station: HERA (Hybrid Electronic Radiation Assessor), which detects radiation events such as solar flares; the ESA (European Space Agency) Active Dosimeters, a wearable device collecting real-time data on individual radiation doses; and the AstroRad Vest, a garment to protect radiation-sensitive organs and tissues. In 2024, researchers released evaluation of data collected in 2022 by these tools that indicate the Orion spacecraft can protect astronauts on lunar missions from potentially hazardous radiation. The orbiting laboratory remains a valuable platform for testing technology for missions beyond Earth’s orbit. The AstroRad Vest, a radiation protection garment, floats in the International Space Station’s cupola.NASA Record participation in Fifth Robo-Pro Challenge A record 661 teams and 2,788 applicants from thirteen countries, regions, and organizations participated in the fifth Kibo Robo-Pro Challenge, which wrapped its final round in September. This educational program from JAXA (Japan Aerospace Exploration Agency) has students solve various problems by programming free-flying Astrobee robots aboard the space station.

NASA/JPL-Caltech Earth planning date: Monday, Jan. 6, 2025 After our marathon holiday plan, we’re easing back into the new year with a standard two-sol plan. We did arrive today to the news that the drive hadn’t made it as far as we wanted, but luckily the rover planners determined that we were still in a good position to do contact science on two wintry targets — “Snow Creek” and “Winter Creek.” We also packed in lots of remote science with ChemCam using LIBS on “Grapevine” and “Skull Rock,” and we are doing long-distance imaging of the Texoli and Wilkerson buttes, and Gould Mesa. Mastcam will be imaging a number of targets near and far as well including “Red Box”’ “Point Mugu,” “Stone Canyon,” “Pine Cove,” and “Hummingbird Sage,” which will examine various structures in the bedrock. We can’t forget about the atmosphere either — we have a couple dust-devil surveys to look for dust lifting, but the real star of the show (at least for me) is the cloud imaging. While we’re just into 2025 here on Earth, we’re also near the start of a new year on Mars! A Mars year starts at the northern vernal equinox (or the start of autumn in the southern hemisphere, where Curiosity is), and Mars year 38 started on Nov. 12. We’re about a third of the way through autumn on Mars now, and the southern Martian autumn and winter bring one thing — clouds! Near the start of the Martian year we start seeing clouds around sunset. These are noctilucent (meaning “night illuminated”) clouds. Even though the sun has set in Gale Crater, the clouds are high enough in the atmosphere that the sun still shines on them, making them seem to almost glow in the sky. You can see this with clouds on Earth, too, around twilight! Mars year 38 will be our fourth year capturing these twilight clouds, and the Navcam images (one of which you can see above) already show it’s shaping up to be another year of spectacular clouds!

Internal view of LignoSat’s structure shows the relationship among wooden panels, aluminum frames, and stainless-steel shafts.Credit: Kyoto University In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites. A previous experiment aboard station exposed three species of wood to the space environment to help researchers determine the best option for LignoSat. The final design used 10 cm long honoki magnolia wood panels assembled with a Japanese wood-joinery method. Researchers will use sensors to evaluate strain on the wood and measure its responses to temperature and radiation in space. Geomagnetic levels will also be monitored to determine whether the geomagnetic field can penetrate the body of the wooden satellite and interfere with its technological capabilities. Investigating uses for wood in space could lead to innovative solutions in the future. A traditional Japanese wooden joining method, the Blind Miter Dovetail Joint, is used for LignoSat to connect two wooden panels without using glue or nails.Credit: Kyoto University Three CubeSats are deployed from space station, including LignoSat.

This photomontage shows tubes containing samples from Mars, as collected by NASA’s Perseverance Mars rover. The agency’s Mars Sample Return Program plans to bring these samples back to study them in state-of-the-art facilities on Earth.Credit: NASA/JPL-Caltech/MSSS To maximize chances of successfully bringing the first Martian rock and sediment samples to Earth for the benefit of humanity, NASA announced Tuesday a new approach to its Mars Sample Return Program. The agency will simultaneously pursue two landing architectures, or strategic plans, during formulation, encouraging competition and innovation, as well as cost and schedule savings. NASA plans to later select a single path forward for the program, which aims to better understand the mysteries of the universe, and to help determine whether the Red Planet ever hosted life. NASA is expected to confirm the program – and its design – in the second half of 2026. “Pursuing two potential paths forward will ensure that NASA is able bring these samples back from Mars with significant cost and schedule saving compared to the previous plan,” said NASA Administrator Bill Nelson. “These samples have the potential to change the way we understand Mars, our universe, and – ultimately – ourselves. I’d like to thank the team at NASA and the strategic review team, led by Dr. Maria Zuber, for their work.” In September 2024, the agency accepted 11 studies from the NASA community and industry on how best to return Martian samples to Earth. A Mars Sample Return Strategic Review team was charged with assessing the studies and then recommending a primary architecture for the campaign, including associated cost and schedule estimates. “NASA’s rovers are enduring Mars’ harsh environment to collect ground-breaking science samples,” said Nicky Fox, who leads NASA’s Science Mission Directorate. “We want to bring those back as quickly as possible to study them in state-of-the-art facilities. Mars Sample Return will allow scientists to understand the planet’s geological history and the evolution of climate on this barren planet where life may have existed in the past and shed light on the early solar system before life began here on Earth. This will also prepare us to safely send the first human explorers to Mars.” During formulation, NASA will proceed with exploring and evaluating two distinct means of landing the payload platform on Mars. The first option will leverage previously flown entry, descent, and landing system designs, namely the sky crane method, demonstrated with the Curiosity and Perseverance missions. The second option will capitalize on using new commercial capabilities to deliver the lander payload to the surface of Mars. For both potential options, the mission’s landed platform will carry a smaller version of the Mars Ascent Vehicle. The platform’s solar panels will be replaced with a radioisotope power system that can provide power and heat through the dust storm season at Mars, allowing for reduced complexity. The orbiting sample container will hold 30 of the sample tubes containing samples the Perseverance lander has been collecting from the surface of Mars. A redesign of the sample loading system on the lander, which will place the samples into the orbiting sample container, simplifies the backward planetary protection implementation by eliminating the accumulation of dust on the outside of the sample container. Both mission options rely on a capture, containment and return system aboard ESA’s (European Space Agency’s) Earth Return Orbiter to capture the orbiting sample container in Mars orbit. ESA is evaluating NASA’s plan.

3 min read 2023 Entrepreneurs Challenge Winner Skyline Nav AI: Revolutionizing GPS-Independent Navigation with Computer Vision NASA sponsored Entrepreneurs Challenge events in 2020, 2021, and 2023 to identify innovative ideas and technologies from small business start-ups with the potential to advance the agency’s science goals. To help leverage external funding sources for the development of innovative technologies of interest to NASA, SMD involved the venture capital community in Entrepreneurs Challenge events. Challenge winners were awarded prize money, and in 2023 the total Entrepreneurs Challenge prize value was $1M. Numerous challenge winners have subsequently received funding from both NASA and external sources (e.g., other government agencies or the venture capital community) to further develop their technologies. Skyline Nav AI, a winner of the 2023 NASA Entrepreneurs Challenge, is pioneering GPS-independent navigation by leveraging cutting-edge computer vision models, artificial intelligence (AI), and edge computing. Skyline Nav AI’s flagship technology offers precise, real-time geolocation without the need for GPS, Wi-Fi, or cellular networks. The system utilizes machine learning algorithms to analyze terrain and skyline features and match them with preloaded reference datasets, providing up to centimeter-level accuracy in GPS-denied environments. This capability could enable operations in areas where GPS signals are absent, blocked, degraded, spoofed, or jammed, including urban canyons, mountainous regions, and the Moon. Skyline Nav AI’s flagship technology at work in New York to provide precise location by matching the detected skyline with a reference data set. The red line shows detection by Skyline Nav AI technology, the green line marks the true location in the reference satellite dataset, and the orange line represents the matched location (i.e., the location extracted from the satellite dataset using Skyline Nav AI algorithms). Skyline Nav’s visual navigation technology can deliver accuracy up to five meters, 95% of the time. The AI-powered visual positioning models continuously improve geolocation precision through pixel-level analysis and semantic segmentation of real-time images, offering high reliability without the need for GPS. In addition to its visual-based AI, Skyline Nav AI’s software is optimized for edge computing, ensuring that all processing occurs locally on the user’s device. This design enables low-latency, real-time decision-making without constant satellite or cloud-based connectivity, making it ideal for disconnected environments such as combat zones or space missions. Furthermore, Skyline Nav AI’s technology can be integrated with various sensors, including inertial measurement units (IMUs), lidar, and radar, to further enhance positioning accuracy. The combination of visual navigation and sensor fusion can enable centimeter-level accuracy, making the technology potentially useful for autonomous vehicles, drones, and robotics operating in environments where GPS is unreliable. “Skyline Nav AI aims to provide the world with an accurate, resilient alternative to GPS,” says Kanwar Singh, CEO of Skyline Nav AI. “Our technology empowers users to navigate confidently in even the most challenging environments, and our recent recognition by NASA and other partners demonstrates the value of our innovative approach to autonomous navigation.” Skyline Nav AI continues to expand its influence through partnerships with organizations such as NASA, the U.S. Department of Defense, and the commercial market. Recent collaborations include projects with MIT, Draper Labs, and AFRL (Air Force Research Laboratory), as well as winning the MOVE America 2024 Pitch competition and being a finalist in SXSW 2024.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Danah Tommalieh, commercial pilot and engineer at Reliable Robotics, inputs a flight plan at the control center in Mountain View, California, ahead of remotely operating a Cessna 208 aircraft at Hollister municipal airport in Hollister, California.NASA/Don Richey NASA recently began a series of flight tests with partners to answer an important aviation question: What will it take to integrate remotely piloted or autonomous planes carrying large packages and cargo safely into the U.S. airspace? Researchers tested new technologies in Hollister, California, that are helping to investigate what tools and capabilities are needed to make these kinds of flights routine. The commercial industry continues to make advancements in autonomous aircraft systems aimed at making it possible for remotely operated aircraft to fly over communities – transforming the way we will transport people and goods. As the Federal Aviation Administration (FAA) develops standards for this new type of air transportation, NASA is working to ensure these uncrewed flights are safe by creating the required technological tools and infrastructure. These solutions could be scaled to support many different remotely piloted aircraft – including air taxis and package delivery drones – in a shared airspace with traditional crewed aircraft. “Remotely piloted aircraft systems could eventually deliver cargo and people to rural areas with limited access to commercial transportation and delivery services,” said Shivanjli Sharma, aerospace engineer at NASA’s Ames Research Center in California’s Silicon Valley. “We’re aiming to create a healthy ecosystem of many different kinds of remotely piloted operations. They will fly in a shared airspace to provide communities with better access to goods and services, like medical supply deliveries and more efficient transportation.” During a flight test in November, Reliable Robotics, a company developing an autonomous flight system, remotely flew its Cessna 208 Caravan aircraft through pre-approved flight paths in Hollister, California. Although a safety pilot was aboard, a Reliable Robotics remote pilot directed the flight from their control center in Mountain View, more than 50 miles away. Cockpit of Reliable Robotics’ Cessna 208 aircraft outfitted with autonomous technology for remotely-piloted operations.NASA/Brandon Torres Navarrete Congressional staffers from the United States House and Senate’s California delegation joined NASA Deputy Associate Administrator for Aeronautics Research Mission Directorate, Carol Caroll, Ames Aeronautics Director, Huy Tran, and other Ames leadership at Reliable Robotics Headquarters to view the live remote flight. Researchers evaluated a Collins Aerospace ground-based surveillance system’s ability to detect nearby air traffic and provide the remote pilot with information in order to stay safely separated from other aircraft in the future. Initial analysis shows the ground-based radar actively surveilled the airspace during the aircraft’s taxi, takeoff, and landing. The data was transmitted from the radar system to the remote pilot at Reliable Robotics. In the future, this capability could help ensure aircraft remain safely separated across all phases of fight. A Reliable Robotics’ modified Cessna 208 aircraft flies near Hollister Airport. A Reliable Robotics pilot operated the aircraft remotely from the control center in Mountain View.NASA/Brandon Torres Naverrete While current FAA operating rules require pilots to physically see and avoid other aircraft from inside the cockpit, routine remotely piloted aircraft will require a suite of integrated technologies to avoid hazards and coordinate with other aircraft in the airspace. A radar system for ground-based surveillance offers one method for detecting other traffic in the airspace and at the airport, providing one part of the capability to ensure pilots can avoid collision and accomplish their desired missions. Data analysis from this testing will help researchers understand if ground-based surveillance radar can be used to satisfy FAA safety rules for remotely piloted flights. NASA will provide analysis and reports of this flight test to the FAA and standards bodies. “This is an exciting time for the remotely piloted aviation community,” Sharma said. “Among other benefits, remote operations could provide better access to healthcare, bolster natural disaster response efforts, and offer more sustainable and effective transportation to both rural and urban communities. We’re thrilled to provide valuable data to the industry and the FAA to help make remote operations a reality in the near future.” Over the next year, NASA will work with additional aviation partners on test flights and simulations to test weather services, communications systems, and other autonomous capabilities for remotely piloted flights. NASA researchers will analyze data from these tests to provide a comprehensive report to the FAA and the community on what minimum technologies and capabilities are needed to enable and scale remotely piloted operations. This flight test data analysis is led out of NASA Ames under the agency’s Air Traffic Management Exploration project. This effort supports the agency’s Advanced Air Mobility mission research, ensuring the United States stays at the forefront of aviation innovation.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) An equal collaboration between NASA and the Indian Space Research Organisation, NISAR will offer unprecedented insights into Earth’s constantly changing land and ice surfaces using synthetic aperture radar technology. The spacecraft, depicted here in an artist’s concept, will launch from India.NASA/JPL-Caltech A Q&A with the lead U.S. scientist of the mission, which will track changes in everything from wetlands to ice sheets to infrastructure damaged by natural disasters. The upcoming U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) mission will observe Earth like no mission before, offering insights about our planet’s ever-changing surface. The NISAR mission is a first-of-a-kind dual-band radar satellite that will measure land deformation from earthquakes, landslides, and volcanoes, producing data for science and disaster response. It will track how much glaciers and ice sheets are advancing or retreating and it will monitor growth and loss of forests and wetlands for insights on the global carbon cycle. As diverse as NISAR’s impact will be, the mission’s winding path to launch — in a few months’ time — has also been remarkable. Paul Rosen, NISAR’s project scientist at NASA’s Jet Propulsion Laboratory in Southern California, has been there at every step. He recently discussed the mission and what sets it apart. NISAR Project Scientist Paul Rosen of NASA’s Jet Propulsion Laboratory first traveled to India in late 2011 to discuss collaboration with ISRO scientists on an Earth-observing radar mission. NASA and ISRO signed an agreement in 2014 to develop NISAR. NASA/JPL-Caltech How will NISAR improve our understanding of Earth? The planet’s surfaces never stop changing — in some ways small and subtle, and in other ways monumental and sudden. With NISAR, we’ll measure that change roughly every week, with each pixel capturing an area about half the size of a tennis court. Taking imagery of nearly all Earth’s land and ice surfaces this frequently and at such a small scale — down to the centimeter — will help us put the pieces together into one coherent picture to create a story about the planet as a living system. What sets NISAR apart from other Earth missions? NISAR will be the first Earth-observing satellite with two kinds of radar — an L-band system with a 10-inch (25-centimeter) wavelength and an S-band system with a 4-inch (10-centimeter) wavelength. Whether microwaves reflect or penetrate an object depends on their wavelength. Shorter wavelengths are more sensitive to smaller objects such as leaves and rough surfaces, whereas longer wavelengths are more reactive with larger structures like boulders and tree trunks. So NISAR’s two radar signals will react differently to some features on Earth’s surface. By taking advantage of what each signal is or isn’t sensitive to, researchers can study a broader range of features than they could with either radar on its own, observing the same features with different wavelengths. Is this new technology? The concept of a spaceborne synthetic aperture radar, or SAR, studying Earth’s processes dates to the 1970s, when NASA launched Seasat. Though the mission lasted only a few months, it produced first-of-a-kind images that changed the remote-sensing landscape for decades to come. It also drew me to JPL in 1981 as a college student: I spent two summers analyzing data from the mission. Seasat led to NASA’s Shuttle Imaging Radar program and later to the Shuttle Radar Topography Mission. What will happen to the data from the mission? Our data products will fit the needs of users across the mission’s science focus areas — ecosystems, cryosphere, and solid Earth — plus have many uses beyond basic research like soil-moisture and water resources monitoring. We’ll make the data easily accessible. Given the volume of the data, NASA decided that it would be processed and stored in the cloud, where it’ll be free to access. How did the ISRO partnership come about? We proposed DESDynI (Deformation, Ecosystem Structure, and Dynamics of Ice), an L-band satellite, following the 2007 Decadal Survey by the National Academy of Sciences. At the time, ISRO was exploring launching an S-band satellite. The two science teams proposed a dual-band mission, and in 2014 NASA and ISRO agreed to partner on NISAR. Since then, the agencies have been collaborating across more than 9,000 miles (14,500 kilometers) and 13 time zones. Hardware was built on different continents before being assembled in India to complete the satellite. It’s been a long journey — literally. More About NISAR The NISAR mission is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. Managed for the agency by Caltech, JPL leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. Space Applications Centre Ahmedabad, ISRO’s lead center for payload development, is providing the mission’s S-band SAR instrument and is responsible for its calibration, data processing, and development of science algorithms to address the scientific goals of the mission. U R Rao Satellite Centre in Bengaluru, which leads the ISRO components of the mission, is providing the spacecraft bus. The launch vehicle is from ISRO’s Vikram Sarabhai Space Centre, launch services are through ISRO’s Satish Dhawan Space Centre, and satellite mission operations are by ISRO Telemetry Tracking and Command Network. National Remote Sensing Centre in Hyderabad is primarily responsible for S-band data reception, operational products generation, and dissemination.

Skywatching Home Skywatching The Next Full Moon is the Wolf… Skywatching Home What’s Up Eclipses Explore the Night Sky Night Sky Network More Tips and Guides FAQ 27 Min Read The Next Full Moon is the Wolf Moon The Moon sets over Homestead National Historic Park in Nebraska. Credits: National Park Service/Homestead The next full Moon is the Wolf Moon; the Ice or Old Moon; the Moon after Yule; the start of Prayag Kumbh Mela; Shakambhari Purnima; Paush Purnima; the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival Moon; and Duruthu Poya. The phases of the Moon for January 2025. NASA/JPL-Caltech The next full Moon will be Monday evening, Jan. 13, 2025, appearing opposite the Sun (in Earth-based longitude) at 5:27 p.m. EST. This will be Tuesday from the South Africa and Eastern European time zones eastward across the remainder of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning. On the night of the full Moon, for most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of the planet Mars. The Maine Farmers’ Almanac began publishing Native American names for full Moons in the 1930s. Over time these names have become widely known and used. According to this almanac, as the full Moon in January this is the Wolf Moon, from the packs of wolves heard howling outside the villages amid the cold and deep snows of winter. European names for this Moon include the Ice Moon, the Old Moon, and (as the full Moon after the winter solstice) the Moon after Yule. Yule was a three to 12-day festival near the winter solstice in pre-Christian Europe. In the tenth century King Haakon I associated Yule with Christmas as part of the Christianization of Norway, and this association spread throughout Europe. The exact timing of this pre-Christian celebration is unclear. Some sources now associate Yule with the 12 days of Christmas, so that the Moon after Yule is after Twelfth Night on January 6. Other sources suggest that Yule is an old name for the month of January, so the Moon after Yule is in February. In the absence of more reliable historic information, I’m going with the full Moon after the winter solstice as the Moon after Yule. This full Moon corresponds with the start of the 44-day festival Prayag Kumbh Mela, also known as Maha Kumbh. This Hindu pilgrimage and festival is held every 12 years in the Indian city of Prayagraj at the confluence of three rivers, the Ganges, the Yamuna, and the mythical Sarasvati. It is expected to draw around 400 million visitors. Similar Kumbh celebrations are held approximately every 12 years at the convergence of three rivers in three other Indian cities, Nashik (upcoming in 2027), Ujjain (in 2028), and Haridwar (in 2033). In the Hindu calendar, this full Moon is Shakambhari Purnima, the last day in the 8-day Shakambari Navratri holiday that celebrates the goddess Shakambhari. In the Purnimanta tradition that ends months on the full Moon day, this full Moon is Paush Purnima, the last day of the Hindu month of Paush. The day after Paush Purnima is the start of the month of Magha, a period of austerity. Bathing in the holy waters of India is an important activity for both Shakambari Navratri and Magha. This full Moon corresponds with the Thiruvathira, Thiruvathirai, or Arudhra Darisanam festival, celebrated by Hindus in the Indian states of Kerala and Tamil Nadu. For the Buddhists of Sri Lanka, this is Duruthu Poya, which commemorates Siddhartha Gautama Buddha’s first visit to Sri Lanka. In many lunar and lunisolar calendars the months change with the new Moon and full Moons fall in the middle of the lunar month. This full Moon is in the middle of the 12th and final month of the Chinese Year of the Rabbit. The new Moon on January 29 will be Chinese New Year, the start of the Year of the Snake. This full Moon is in the middle of Tevet in the Hebrew calendar and Rajab, the seventh month of the Islamic calendar. Rajab is one of the four sacred months in which warfare and fighting are forbidden. As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Take care in the cold weather and take advantage of these early sunsets to enjoy and share the wonders of the night sky. And avoid starting any wars. Here are the other celestial events between now and the full Moon after next, with times and angles based on the location of NASA Headquarters in Washington, D.C.: As winter continues in the Northern Hemisphere, the daily periods of sunlight continue to lengthen. Our 24-hour clock is based on the average length of a day with the solar days near the solstices longer than those near the equinoxes. For Washington, D.C. and similar latitudes (I’ve not checked for other areas) the latest sunrise of the year (ignoring Daylight Saving Time) occurred on January 4. Monday, January 13 (the day of the full Moon), morning twilight will begin at 6:24 a.m. EST, sunrise will be at 7:26 a.m., solar noon will be at 12:17 p.m. when the Sun will reach its maximum altitude of 29.8 degrees, sunset will be at 5:08 p.m., and evening twilight will end at 6:11 p.m. By Wednesday, February 12 (the day of the full Moon after next), morning twilight will begin at 6:04 a.m., sunrise will be at 7:03 a.m., solar noon will be at 12:23 p.m. when the Sun will reach its maximum altitude of 37.7 degrees, sunset will be at 5:43 p.m., and evening twilight will end at 6:41 p.m. This should be a good time for planet watching, especially with a backyard telescope. Venus, Jupiter, Mars, Saturn, and Uranus will all be in the evening sky. Brightest will be Venus, appearing in the southwestern sky. With a telescope you should be able to see it shift from half-full to a 29% illuminated crescent during this lunar cycle as it brightens and moves closer to the Earth. Venus will reach its brightest for the year just after the full Moon after next. Second in brightness will be Jupiter in the eastern sky. With a telescope you should be able to see Jupiter’s four bright moons, Ganymede, Callisto, Europa, and Io, noticeably shifting positions in the course of an evening. Jupiter was at its closest and brightest in early December. Third in brightness will be Mars low in the east-northeastern sky. Mars will be at its closest and brightest for the year a few days after this full Moon. Fourth in brightness will be Saturn, appearing near Venus in the southwestern sky. With a telescope you should be able to see Saturn’s bright moon Titan and maybe its rings. The rings are appearing very thin and will be edge-on to the Earth in March 2025. We won’t get the “classic” view of Saturn showing off its rings until 2026. Saturn was at its closest and brightest in early September and will appear its closest to Venus (2.2 degrees apart) the evening of January 18. Fifth in brightness and technically bright enough to see without a telescope (if you are in a very dark location and your eyesight is better than mine) will be Uranus high in the southeastern sky. Uranus was at its closest and brightest in mid-November. During this lunar cycle these planets will be rotating westward around the pole star Polaris (with Venus shifting more slowly) making them easier to see earlier in the evening, and friendlier for backyard stargazing, especially if you have young ones with earlier bedtimes. Comets As mentioned in my last posting, the sungrazing comet C/2024 G3 (ATLAS) will be passing very near the Sun on January 13. There is a chance that this comet will break up and vanish from view as it approaches the Sun, much as comet C/2024 S1 (ATLAS) did in October. In addition, its visual magnitude might not be bright enough to see in the daytime due to the glow of the nearby Sun. If it does not break up and is bright enough, Northern Hemisphere viewers will have the best viewing near its closest approach. For the Washington, D.C. area, it could be brightest the evening of January 12 before it sets on the southwestern horizon. You will need to find a distant object to block direct sunlight so you can safely look about 5 degrees to the upper right of the Sun. If the horizon is very clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. Southern Hemisphere viewers will have the best viewing after closest approach, immediately after sunset from mid-January on (dimming each evening as it moves away from the Sun and the Earth). You may need binoculars or a telescope to see it, although comets are hard to predict. Meteor Showers Two minor meteor showers, the γ-Ursae Minorids (404 GUM) and α-Centaurids (102 ACE), will peak during this lunar cycle. The light of the waning Moon will interfere with the γ-Ursae Minorids peak on January 18. The α-Centaurids, only visible from the Southern Hemisphere, are expected to peak on February 8. In recent years the average peak has been 6 visible meteors per hour (under ideal conditions), although this shower showed bursts of 20 to 30 meteors per hour in 1974 and 1980. The best viewing conditions will likely be after the waxing gibbous Moon sets in the early mornings around the peak. Evening Sky Highlights On the evening of Monday, Jan. 13, 2025 (the evening of the full Moon), as twilight ends (at 6:11 p.m. EST), the rising Moon will be 13 degrees above the east-northeastern horizon with the bright planet Mars (the third brightest planet) 2 degrees to the lower left and the bright star Pollux (the brighter of the twin stars in the constellation Gemini, the twins) 3 degrees to the upper left of the Moon. The brightest planet visible will be Venus at 29 degrees above the southwestern horizon, with the planet Saturn (fourth brightest) 6 degrees to the upper left of Venus. The second brightest planet, Jupiter, will be 47 degrees above the eastern horizon. The bright star closest to overhead will be Capella at 50 degrees above the east-northeastern horizon. Capella is the 6th brightest star in our night sky and the brightest star in the constellation Auriga (the charioteer). Although we see Capella as a single star it is actually four stars (two pairs of stars orbiting each other). Capella is about 43 light years from us. As this lunar cycle progresses, the planets and the background of stars will appear to rotate westward around the pole star Polaris each evening, with Venus initially shifting the other direction. Mars will be at its closest and brightest on January 15. Venus and Saturn will appear closest to each other on January 18. Mars and Pollux will appear nearest each other on January 22 and 23. Venus will appear at its highest above the horizon (as twilight ends) on January 27, after which it will start shifting toward the horizon again. Jupiter and Aldebaran will appear at their closest on January 31. The waxing Moon will pass by Saturn on January 31; Venus on February 1; the Pleiades star cluster on February 5; and Mars and Pollux on February 10. By the evening of Wednesday, February 12 (the evening of the full Moon after next), as twilight ends (at 6:41 p.m. EST), the rising Moon will be 7 degrees above the east-northeastern horizon with the bright star Regulus 2 degrees to the right. The brightest planet in the sky will be Venus at 28 degrees above the west-southwestern horizon, appearing as a crescent through a telescope. Next in brightness will be Jupiter at 71 degrees above the south-southeastern horizon. Third in brightness will be Mars at 48 degrees above the eastern horizon. Saturn will be 11 degrees above the west-southwestern horizon. Uranus, on the edge of what is visible under extremely clear, dark skies, will be 68 degrees above the south-southwestern horizon. The bright star closest to overhead will still be Capella at 75 degrees above the northeastern horizon. Also high in the sky will be the constellation Orion, easily identifiable because of the three stars that form Orion’s Belt. This time of year, we see many bright stars in the sky at evening twilight, with bright stars scattered from the south-southeast toward the northwest. We see more stars in this direction because we are looking toward the Local Arm of our home galaxy (also called the Orion Arm, Orion-Cygnus Arm, or Orion Bridge). This arm is about 3,500 light years across and 10,000 light years long. Some of the bright stars we see from this arm are the three stars of Orion’s Belt, as well as Rigel (860 light years from Earth), Betelgeuse (548 light years), Polaris (about 400 light years), and Deneb (about 2,600 light years). Facing toward the south from the northern hemisphere, to the upper left of Orion’s Belt is the bright star Betelgeuse (be careful not to say this name three times). About the same distance to the lower right is the bright star Rigel. Orion’s belt appears to point down and to the left about seven belt lengths to the bright star Sirius, the brightest star in the night sky. Below Sirius is the bright star Adara. To the upper right of Orion’s Belt (at about the same distance from Orion as Sirius) is the bright star Aldebaran. Nearly overhead is the bright star Capella. To the left (east) of Betelgeuse is the bright star Procyon. The two stars above Procyon are Castor and Pollux, the twin stars of the constellation Gemini (Pollux is the brighter of the two). The bright star Regulus appears farther to the left (east) of Pollux near the eastern horizon. Very few places on the East Coast are dark enough to see the Milky Way (our home galaxy), but if you could see it, it would appear to stretch overhead from the southeast to the northwest. Since we are seeing our galaxy from the inside, the combined light from its 100 billion to 400 billion stars make it appear as a band surrounding the Earth. Morning Sky Highlights On the morning of Monday, Jan. 13, 2025 (the morning of the full Moon), as twilight begins (at 6:23 a.m. EST), the setting full Moon will be 11 degrees above the west-northwestern horizon. This will be the last morning the planet Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so. This will leave Mars at 18 degrees above the west-northwestern horizon as the only planet in the sky. The bright star appearing closest to overhead will be Arcturus at 69 degrees above the south-southeastern horizon. Arcturus is the brightest star in the constellation Boötes (the herdsman or plowman) and the 4th brightest star in our night sky. It is 36.7 light years from us. While it has about the same mass as our Sun, it is about 2.6 billion years older and has used up its core hydrogen, becoming a red giant 25 times the size and 170 times the brightness of our Sun. One way to identify Arcturus in the night sky is to start at the Big Dipper, then follow the arc of the dipper’s handle as it “arcs toward Arcturus.” As this lunar cycle progresses Mars and the background of stars will appear to rotate westward around the pole star Polaris by about 1 degree each morning. The waning Moon will appear near Mars and Pollux on January 13 and 14, Regulus on January 16, Spica on January 21, Antares on January 24 and 25, and (rising after morning twilight begins) Mercury on January 28. January 22 will be the last morning the planet Mercury will be above the horizon 30 minutes before sunrise. Mars and Pollux will be near their closest to each other the morning of January 23. February 4 will be the last morning the planet Mars will be above the northwestern horizon as morning twilight begins. The waxing Moon will appear near Pollux on February 9 (setting before twilight begins) and 10. By the morning of Wednesday, February 12 (the morning of the full Moon after next), as twilight begins (at 6:04 a.m. EST), the setting full Moon will be 13 degrees above the western horizon. No planets will appear in the sky. The bright star appearing closest to overhead will still be Arcturus at 65 degrees above the southeastern horizon. Detailed Daily Guide Here is a day-by-day listing of celestial events between now and the full Moon on Feb. 12, 2025. The times and angles are based on the location of NASA Headquarters in Washington, D.C., and some of these details may differ for where you are (I use parentheses to indicate times specific to the D.C. area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app set for your location or a star-watching guide from a local observatory, news outlet, or astronomy club. Tuesday evening, January 7 At 7:07 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit. Thursday evening, January 9 The waxing gibbous Moon will pass in front of the Pleiades star cluster. This may be viewed best with binoculars, as the brightness of the Moon will make it hard to see the stars in this star cluster. As evening twilight ends at 6:07 p.m. EST, the Pleiades will appear 1 degree to the lower left of the full Moon. Over the next few hours, including as the Moon reaches its highest for the night at 8:37 p.m., the Moon will pass in front of the Pleiades, blocking many of these stars from view. By about midnight the Pleiades will appear about 1 degree below the Moon, and the Moon and the Pleiades will separate as Friday morning progresses. Also on Thursday night, January 9, the planet Venus will reach its greatest angular separation from the Sun as seen from the Earth for this apparition (called greatest elongation). Because the angle between the line from the Sun to Venus and the line of the horizon changes with the seasons, the date when Venus and the Sun appear farthest apart as seen from Earth is not always the same as when it appears highest above the west-southwestern horizon as evening twilight ends, which occurs on January 27. Friday evening, January 10 The bright planet Jupiter will appear near the waxing gibbous Moon. As evening twilight ends at 6:08 p.m. EST, Jupiter will be 5 degrees to the lower right. As the Moon reaches its highest for the night at 9:37 p.m., Jupiter will be 6 degrees below the Moon. The pair will continue to separate until Jupiter sets Saturday morning at 4:45 a.m. Sunday afternoon, January 12 There is a slight chance that the sungrazing comet, C/2024 G3 (ATLAS) might be visible near the setting Sun. Most likely, this comet will not be bright enough to see in the daytime or will break up and vanish from view like comet C/2024 S1 (ATLAS) did in October. The odds are low, but if the sky is clear, find an object to block direct sunlight (the farther away the object the better) so you can safely look about 5 degrees to the upper right of the Sun. If the west-southwestern horizon is clear, your best chance might be after sunset at 5:07 p.m. EST, but before the comet sets about 10 minutes later. This will only be visible from the Northern Hemisphere. Southern Hemisphere viewers may be able to see this comet from mid-January on immediately after sunset (dimming each evening as it moves away from us). Monday morning, January 13 This is the morning of the full Moon. It will be the last morning Mercury will rise before morning twilight begins, although it will be bright enough to see in the glow of dawn after it rises for another week or so. The Moon will be full Monday evening at 5:27 p.m. EST. This will be on Tuesday from the South Africa and Eastern European time zones eastward across the rest of Africa, Europe, Asia, Australia, etc., to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Sunday evening (and possibly the last part of Sunday morning) into Wednesday morning. On Monday night the full Moon will appear near and pass in front of the bright planet Mars, with the bright star Pollux above the pair. As evening twilight ends at 6:11 p.m. EST, the three will form a triangle, with Mars 2 degrees to the lower left and Pollux 3 degrees to the upper left of the Moon. For most of the continental USA as well as parts of Africa, Canada, and Mexico, the Moon will pass in front of Mars. Times will vary for other locations, but for NASA Headquarters in Washington, D.C., Mars will vanish behind the bottom of the Moon at about 9:16 p.m. and reappear from behind the upper right of the Moon at about 10:31 p.m. By the time the Moon reaches its highest for the night early on Tuesday morning at 12:37 a.m., Mars will be 1 degree to the right of the Moon and Pollux 5 degrees to the upper right. As morning twilight begins at 6:23 a.m., Mars will be 4 degrees and Pollux 8 degrees to the lower right of the Moon. Wednesday night January 15 The planet Mars will be at opposition, so called because it will be opposite the Earth from the Sun, effectively a “full” Mars. Near opposition Mars will be at its closest and brightest for the year. On Wednesday night, as evening twilight ends at 6:13 p.m. EST, Mars will be 14 degrees above the east-northeastern horizon. Mars will reach its highest in the sky early Thursday morning at 12:21 a.m., and will be 15 degrees above the west-northwestern horizon as morning twilight begins at 6:23 a.m. Only planets that orbit farther from the Sun than the Earth can be seen at opposition from the Earth. Wednesday night into Thursday morning, January 15 to 16 The bright star Regulus will appear near the waning gibbous Moon. As Regulus rises on the east-northeastern horizon at 7:52 p.m. EST, it will be more than 8 degrees below the Moon. By the time the Moon reaches its highest for the night on Thursday morning at 2:17 a.m. Regulus will be 5.5 degrees to the lower left of the Moon. As morning twilight begins at 6:23 a.m. Regulus will be 4 degrees to the left of the Moon. Saturday evening, January 18 Venus and Saturn will appear nearest to each other. As evening twilight ends at 6:15 p.m. EST, Venus will be 30 degrees above the southwestern horizon with Saturn 2.2 degrees to the lower left. Saturn will set first on the western horizon almost 3 hours later at 9:04 p.m. Monday night, January 20 At 11:53 p.m. EST, the Moon will be at apogee, its farthest from the Earth for this orbit. Tuesday morning, January 21 The bright star Spica will appear near the waning gibbous Moon. As the Moon rises on the east-southeastern horizon at 12:11 a.m. EST Spica will be 1 degree above the Moon. By the time the Moon reaches its highest for the night at 5:41 a.m., Spica will be 3.5 degrees to the upper right, with morning twilight beginning 40 minutes later at 6:21 a.m. For parts of Western Africa and the Atlantic Ocean the Moon will pass in front of Spica. Tuesday afternoon, the waning Moon will appear half-full as it reaches its last quarter at 3:31 p.m. EST (when we can’t see it). Wednesday morning, January 22 This will be the last morning Mercury will be above the horizon 30 minutes before sunrise, an approximation of the last morning it might be visible in the glow of dawn. Throughout this lunar cycle, Mars and the bright star Pollux will appear near each other, with Wednesday night into Thursday morning and Thursday night into Friday morning (January 22, 23, and 24) the nights when they will be at their closest, 2.5 degrees apart. They will be up all night for both nights, with Mars at its highest on Wednesday night at 11:41 p.m. EST, and Thursday night at 11:36 p.m. Friday morning, January 24 The bright star Antares will appear to the lower left of the waning crescent Moon. As Antares rises on the southeastern horizon at 3:54 a.m. EST, it will be 8 degrees from the Moon. By the time morning twilight begins less than 2.5 hours later at 6:19 a.m., Antares will be 6.5 degrees from the Moon. For part of the Indian Ocean the Moon will actually pass in front of Pollux. Saturday morning, January 25 The Moon will have shifted to the other side of Antares. As the Moon rises at 4:20 a.m. EST, Antares will be 6 degrees to the upper right of the Moon. By the time morning twilight begins 2 hours later at 6:19 a.m., Antares will be 7 degrees from the Moon. Monday evening, January 27 Venus will be at its highest above the west-southwestern horizon (31 degrees) as evening twilight ends at 6:25 p.m. EST, appearing as a 41% illuminated crescent through a telescope. Wednesday morning, January 29 At 7:36 a.m. EST there will be a new Moon, when the Moon passes between the Earth and the Sun, and the Moon will not be visible from the Earth. The day of, or the day after, the New Moon marks the start of the new month for most lunisolar calendars. The first month of the Chinese calendar starts on Wednesday, January 29, making this Chinese New Year, the start of the Year of the Snake! Chinese New Year and related celebrations throughout much of Asia and in areas with significant Chinese populations celebrate the end of winter and start of spring. Traditional festivities start on the eve of Chinese New Year and continue until the Lantern Festival on the 15th day of the first lunar month. Sundown on Wednesday, January 29 This marks the start of Shevat in the Hebrew calendar. Sundown on Thursday, January 30 In the Islamic calendar, the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Thursday, January 30, will probably mark the beginning of Shaʿbān, the eighth month of the Islamic year and the month before Ramadan. Friday evening, January 31 Saturn will appear 4 degrees to the upper left of the waxing crescent Moon. The Moon will be 17 degrees above the west-southwestern horizon as evening twilight ends at 6:29 p.m. EST, and will set on the western horizon 99 minutes later at 8:08 p.m. For part of Asia the Moon will actually pass in front of Saturn. Throughout this lunar cycle the bright star Aldebaran will appear below the bright planet Jupiter, with Friday, January 31 the evening they appear at their closest, about 5 degrees apart. As evening twilight ends at 6:29 p.m. EST, Jupiter will be 65 degrees above the southeastern horizon with Aldebaran to the lower right. Jupiter will reach its highest for the night, 73 degrees above the southern horizon at 8:01 p.m., with Aldebaran below Jupiter. As Aldebaran sets on the west-northwestern horizon almost 7 hours after that at 2:56 a.m. it will be to the lower left of the Moon. Saturday evening, February 1 Venus will appear near the waxing crescent Moon. The Moon will be 30 degrees above the west-southwestern horizon as evening twilight ends at 6:30 p.m. EST, with Venus 2.5 degrees to the upper right. Venus will be 2.5 degrees to the lower right as it sets first on the western horizon 2.75 hours later at 9:15 p.m. Saturday night, at 9:38 p.m. EST, the Moon will be at perigee, its closest to the Earth for this orbit. Saturday also is Imbolc or Imbolg, and the next day (Sunday, February 2) is Candlemas or Groundhog’s Day. We currently divide the year into four seasons based upon the solstices and equinoxes, with spring starting on the vernal equinox. This approximates winter as the quarter of the year with the coldest temperatures. Much of pre-Christian northern Europe celebrated “cross-quarter days” halfway between the solstices and equinoxes, dividing the seasons on these days. Using this definition, winter was the quarter of the year with the shortest daily periods of daylight, and spring started on Imbolc (the middle of our winter). The tradition in some European countries was to leave Christmas decorations up until February 1st, the eve of Candlemas, and it was considered bad luck to leave decorations up past this date. Robert Herrick (1591-1674) starts his poem “Ceremonies for Candlemas Eve” with “Down with the rosemary and bays, down with the mistletoe; Instead of holly, now up-raise the greener box (for show).” We have a tradition in the United States that winter will end on Groundhog Day if the groundhog sees its shadow. If not, winter will last six weeks more (ending around the time of the spring equinox). Groundhog Day appears to tie back to European lore about whether or not badgers, wolves, or bears (instead of groundhogs) see their shadows. Many believe that these Groundhog Day and Candlemas traditions tie back to these earlier celebrations for the start of spring. It seems plausible to me that it was confusing to have two competing dates for the end of winter. Perhaps it was best to let a natural event such as an animal’s shadow decide which definition to use, rather than arguing with your neighbors for the next six weeks. Tuesday morning, February 4 This will be the last morning Mars will be above the northwestern horizon as morning twilight begins. Wednesday morning, February 5 The Moon will appear half-full as it reaches its first quarter at 3:02 a.m. EST (when we can’t see it). Wednesday evening the waxing gibbous Moon will appear near the Pleiades star cluster. As evening twilight ends at 6:34 p.m. EST, this star cluster will be 5 degrees to the upper left of the Moon. The Pleiades will shift closer toward the Moon until the Moon sets on the west-northwestern horizon less than 8 hours later at 2:16 a.m. Some North American locations farther west will actually see the Moon pass in front of some of the stars in the Pleiades. Sunday morning, February 9 Mars will appear to the upper left of the waxing gibbous Moon. In the early morning at about 2 a.m. EST, Mars will be 8 degrees from the Moon. By the time the Moon sets on the northwestern horizon at 5:58 a.m., Mars will have shifted to 6 degrees from the Moon. For parts of Asia and Northern Europe the Moon will pass in front of Mars. Also Sunday morning, Mercury will be passing on the far side of the Sun as seen from the Earth, called superior conjunction. Because Mercury orbits inside of the orbit of Earth it will be shifting from the morning sky to the evening sky and will begin emerging from the glow of dusk on the west-southwestern horizon after about February 17 (depending upon viewing conditions). Sunday evening into Monday morning, February 9 to 10 The waxing gibbous Moon will have shifted to the other side of Mars (having passed in front of Mars in the afternoon when we could not see them). As evening twilight ends at 6:38 p.m. EST, the Moon will be between Mars and the bright star Pollux, with Mars 3 degrees to the upper right and Pollux 3 degrees to the lower left. By the time the Moon reaches its highest for the night at 10:27 p.m., Mars will be 4.5 degrees to the right of the Moon and Pollux 2.5 degrees to the upper left of the Moon. Mars will set first on the northwestern horizon Monday morning at 5:44 a.m. just 22 minutes before morning twilight begins at 6:06 a.m. Wednesday morning, February 12 The full Moon after next will be at 8:53 a.m. EST, with the bright star Regulus nearby. This will be on Thursday morning from Australian Central Time eastward to the International Date Line in the mid-Pacific. The Moon will appear full for about three days around this time, from Monday night into early Thursday evening.

NASA In this Dec. 11, 1963, image, technicians prepare a test subject for studies on the Reduced Gravity Walking Simulator at NASA’s Langley Research Center in Hampton, Virginia. This position meant that a person’s legs experienced only one sixth of their weight, which was the equivalent of being on the Moon’s surface. The simulator was used to study the subject while walking, jumping, or running; it also was used to train Apollo astronauts for completing tasks in the unfamiliar lunar environment. The effect was quite realistic. When asked what it was like to land on the Moon, Neil Armstrong replied, “Like Langley.” Image credit: NASA View the full article
