Appearing before local news cameras and reporters, Pelfrey said he was humbled and honored to receive the call from NASA Administrator Bill Nelson with news of his selection.

“The agency is committed to Marshall’s role in supporting what we do as a nation in space exploration,” Pelfrey said. “I am honored that they have confidence in me and our team to continue to lead.”

Pelfrey took the opportunity to speak to reporters about upcoming milestones for the center, such as the celebration of 25 years of work with the Chandra X-ray Observatory, Marshall’s 30th year hosting the Human Exploration Rover Challenge, two years since the launches of the James Webb Space Telescope and IXPE (Imaging X-ray Polarimetry Explorer) observatory, and the recent launch of the LN-1 (Lunar Node 1) navigation beacon.

He also discussed the center’s plans to use more of its testing capabilities for habitation systems; build a new Engineering Science Laboratory to replace Building 4487; build the Marshall Exploration Facility where Building 4200 once stood; and continue supporting operations at the International Space Station and for future Artemis missions.

Looking to the future, Pelfrey said Marshall is focused on helping NASA expand its missions in deep space and developing the technologies needed to carry astronauts farther than “we’ve ever been before.”

A child of the shuttle generation, Pelfrey recalled watching launches and dreaming of a career at NASA. He said he’s honored to follow behind great center leaders, continuing Marshall’s legacy as a leader in space exploration.

“As we write the next chapter of our story, I am confident of the bright future we have at Marshall Space Flight Center,” he said.

Along with Pelfrey, Tia Ferguson, director of Marshall’s Space Systems Department in the Engineering Directorate, Rae Ann Meyer, associate center director, and Mallory James, an aerospace engineer and management assistant in the office of the center director, gave presentations about the direction of Marshall in 2024.

“I see us embracing a transformative shift to a portfolio of more small and medium-sized projects enabled through strategic partnerships while also being a technical solutions provider to NASA and our partners,” Pelfrey said. “I see a very bright future for our center, and I’m excited to write this next chapter with all of you.”

Pelfrey commended Marshall team members for submitting 63 proposals to NASA’s Space Technology Mission Directorate, all enabled by partnerships. Marshall submitted and won the most proposals out of all NASA centers. He encouraged team members to continue creating and working on more innovative ideas to support future Agency needs.

Pelfrey gave updates on Marshall’s various projects, including Lunar Node-1 using the Huntsville Operation Support Center for its mission and Marshall partnering with the Italian Space Agency to create a multipurpose habitat that could be used on the Moon. The habitat is in the process of becoming a part of the Artemis architecture and would be the first of its kind on the lunar surface.

Pelfrey shared that Marshall and industry partners will be leading the development of the engine in collaboration with the Department of the Defense for NASA and DARPA’s DRACO (Demonstration Rocket for Agile Cislunar Operations), the first nuclear thermal flight demonstration intended for the mission to Mars. Pelfrey also highlighted the development of the solar sail prototype, which is approximately 4,700 square feet and was recently tested with NASA’s industry partner. The potential for this design has drawn attention from future science missions and the Department of Defense due to its advancements in propulsion.

Pelfrey also mentioned that NASA’s Michoud Assembly Facility, which is managed by Marshall, is manufacturing parts for Artemis III-V. Pertaining to the Artemis Mission, Pelfrey said the data from Artemis I is being examined to prepare for Artemis II. Flight software testing has been completed for Artemis II as well. The Human Landing System team is continuing to work with lander partner, SpaceX, which is preparing for the next Starship orbital flight test in the next few weeks.

According to Pelfrey, Marshall is also expecting two new buildings, the Marshall Exploration Facility, which is tentatively scheduled to break ground in 2026, and an Engineering Science Lab, a replacement for Building 4487.

Ferguson followed Pelfrey’s presentation with updates about NASA 2040, an agency strategic initiative propelling NASA into the future. The initiative aims to drive meaningful changes in the present to ensure that, in 2040, NASA remains the preeminent institution for research, technology, and engineering, to lead science, aeronautics, and space exploration for humanity. She went into detail about plans made to optimize the internaloperations of the agency and improving the work environment for team members to achieve mission goals.

Meyer discussed how Marshall’s culture reflects the changes and new strategies taking place. Meyer emphasized the investment in centerwide events to strengthen culture at Marshall.

James, a mentee of Meyer, gave the last presentation. She discussed the results of the Federal Employee Viewpoint Survey and how leadership is moving forward to address concerns expressed from the results. 

All-hands ended with a Q&A panel with Pelfrey, Ferguson, Meyer, and James. Larry Leopard, associate director, technical, also joined the panel. They answered questions submitted online and from the audience.

“With our long history of what we’ve done at the center, there’s so much more to Marshall that we can achieve,” Pelfrey said in his closing remarks. “There’s so much more that we can dare to dream and explore and innovate for the agency and there’s more to gain when we do it together.”

Black History Month Profile: Evolving with Leslie Smith

By Celine Smith

Ever since Leslie Smith was young, she has liked working with her hands, whether it be arts and crafts or playing the piano. Watching her father weld pieces of scrap metal into something new reinforced her enthusiasm for designing and creating.

While working for NASA’s Marshall Space Flight Center, Smith has been able to pursue her passion of more tactile work while also gaining an array of other skills.

“Helping put the next man and first woman on the Moon gives me a sense of pride, especially because it could help us get to Mars,” said Smith, who is the task manager of the Sustaining Lunar Development program. “I love knowing I’m helping the next generation and just being a part of the program.”

As a young girl, Smith aspired to be an architect, which combined her two favorite skills of designing and building. While in high school, Smith began to co-op at a technical vocational school. Her interest in architecture increased when she was introduced to CAD (computerized-aided design) software in a drafting class.

After Smith started at Tuskegee University, a historically Black university in Alabama, her sights changed. “The architecture class seemed more artsy, and not as focused on design or manufacturing, which is what I really wanted to do,” said Smith, who is from Vicksburg, Mississippi.

She decided to major in mechanical engineering instead. Before graduating, Smith signed an offer for a co-op opportunity with Marshall during a 2008 Tuskegee job fair, leading to her 15-year career at the center.

During Smith’s start, she didn’t get to immediately do the CAD work she originally was drawn to. Smith began working in the Planning and Operations branch within the Mission Ops Lab. She oversaw the countdown timeline for operational tasks and filled out functional objective sheets for the Constellation program’s Ares I. Later, she performed 3D CAD modeling for the main propulsion system and 2D drawings and assemblies for the cryogenic propellant storage and transfer system.

The experience served as Smith’s introduction to program management and systems engineering. While her role was not originally in her area of interest, she found a reason to stay.

“I stayed because of the people,” Smith said. “They were very friendly and helpful. Also, after taking a tour of Marshall, I saw all capabilities of the center. Marshall’s friction stir welding, 3D printing, the propulsion lab, and the diverse types of engineering intrigued me.”

Her first full-time role at Marshall took place after graduating college. She began as a design engineer in the Propulsion Detailed Design branch in 2013. She used her CAD skills to draft a 1 Newton thruster, an adapter for secondary payloads, and a core stage auxiliary power unit among other projects. Smith also did some friction stir welding and additive manufacturing, the processes that interested her during her co-op days. Before becoming a key coordinator for human landing systems, she conducted trade studies for SLS (Space Launch System) components as a systems engineer in 2018. Now, Smith manages human landing system concepts, focused on reducing risk and the advancement of key technologies.

“I’m the kind of person who likes to do something different every so often,” she said. “Technology is always evolving so that makes me want to always evolve.”

Smith’s passion for engineering is present in her personal life. As a member of the National Society of Black Engineers, she took part in the Arusha Project, started at NASA’s Johnson Space Center. Arusha is Swahili for “he makes fly (into the skies).” Smith joined other Black engineers to build a rover for potential Moon and Mars missions. Smith personally worked on the outer shell, window, and chassis.

“The project was great because you got to work with other African American engineers and other ethnicities,” she said. “It’s important to be around people who look like you and can relate to similar issues.” 

In Smith’s free time she volunteers to do STEM outreach. She also enjoys basketball, swimming, and reading. Smith currently lives in Madison, Alabama.

Her advice for young engineers at Marshall is to: “learn all you can. Talk to as many people as you can, particularly people who are different from you for a different perspective. Never pass an opportunity to see hardware. Take all the tours and attend mentoring events.”

By Wayne Smith

Bob Conway, deputy director of the NASA Safety Center, will be the guest speaker for the Mission Success Is in Our Hands hybrid Shared Experiences Forum on Feb. 22 at NASA’s Marshall Space Flight Center.

The 11:30 a.m. event will be in Activities Building 4316 for Marshall team members. Light refreshments will be served. The forum is available to NASA employees and the public virtually via Teams.

Mission Success with Bob Conway flyer

Mission Success Is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs Engineering. The initiative’s goal to help team members make meaningful connections between their jobs and the safety and success of NASA and Marshall missions.

The theme of the forum is “The Impact of Breaking the Silence.” Conway will address the elements and factors that can contribute to organizational silence, including the failure to draw attention to problems that can potentially result in mission failures. He will detail practical tactics and tools to help combat this issue and identify methods of creating organizational excellence from the perspectives of both leadership and front-line employees.

Bill Hill, director of Safety and Mission Assurance at Marshall, encourages team members to attend the forum in-person.

“Administrator (Bill) Nelson has requested that all NASA civil servants and contractors hear Bob Conway’s organizational silence briefing and learn tools and techniques to avoid the pitfalls of organizational silence,” Hill said.

Jeff Haars, Jacobs vice president and program manager for Jacobs Space Exploration Group, said the Shared Experiences Forum is an impactful reminder on safety.

“At Jacobs, we put a high priority on safety so it’s very reassuring to have a great safety partner like Marshall,” Haars said. “Working as a team allows us to deliver our work safely while contributing to mission success.”

Conway works with the NASA Safety Center’s director to enable more effective and efficient safety and mission assurance support for NASA’s portfolio of programs and projects by managing the safety center’s activities in knowledge sharing and analysis, technical excellence, and assessments and investigations.

Prior to assuming this role, Conway worked in the civilian sector as the manager of Quality Engineering for Worldwide Safety and Health at the Walt Disney World Resort in Orlando, Florida, from 2012 to 2019. Conway was also a member of the NASA Aerospace Safety Advisory Panel from 2012 to 2016. In this role he evaluated various NASA programs and, with his Naval Aviation Safety background, was the lead panel representative to the NASA Aircraft Mission Directorate. After his commissioning as an ensign, Conway served in the U.S. Navy through his retirement in 2012.

As part of the forum, Mission Success Is in Our Hands will present the Golden Eagle Award to a Marshall team member. The award promotes awareness and appreciation for flight safety, as demonstrated through the connections between employees’ everyday work, the success of NASA and Marshall’s missions, and the safety of NASA astronauts. The award recognizes individuals who have made significant contributions to flight safety and mission assurance above and beyond their normal work requirements. Management or peers can nominate any team member for the award. Honorees are typically recognized at quarterly Shared Experiences forums.

NASA Science Aboard Intuitive Machines Continues Journey to Moon, Landing Coverage set for Feb. 22

After a successful launch Feb. 15, six NASA science instruments and technology demonstrations continue their journey to the Moon aboard Intuitive Machines’ lander named Odysseus. The company confirmed communications contact with its mission operations control in Houston, and its lander continues to perform as expected.

As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines is targeting no earlier than 4:49 p.m. CST on Feb. 22 to land their Odysseus lunar lander near Malapert A in the South Pole region of the Moon.

Live landing coverage will air on NASA+NASA Television, the NASA app, and the agency’s website. NASA TV can be streamed on a variety of platforms, including social media. Coverage will include live streaming and blog updates beginning 3:15 p.m., as the landing milestones occur. Upon successful landing, Intuitive Machines and NASA will host a news conference to discuss the mission and science opportunities that lie ahead as the company begins lunar surface operations.

Known as IM-1, Intuitive Machines successfully transmitted its first images back to Earth on Feb. 16. These were captured shortly after separation from SpaceX’s second stage, on Intuitive Machines’ first journey to the Moon.

Within an hour of launching, NASA confirmed data was streaming from the agency’s powered science and technology instruments aboard the flight. This means data from these instruments was automatically streaming back to the teams so NASA could monitor the health and status of its instruments.

Later, Intuitive Machines successfully commissioned Odysseus’ engine which means they exercised the engine’s complete flight profile, including the throttling required for landing. The engine, which uses liquid methane and liquid oxygen, is the first of its kind fired in space.

One of the NASA instruments, the Radio Frequency Mass Gauge is gauging the cryogenic propellants on Odysseus throughout the mission. Data files have been collected and many have been downloaded for analysis. Throughout the propellant loading phase that took place before launch, the instrument collected data, which was downloaded and analyzed in near-real time. Data also is being collected during the microgravity transit phase of the mission. This analysis will continue through landing on the Moon.

Another NASA instrument, Lunar Node-1, or LN-1, integrates navigation and communication . LN-1 was developed, built, and tested at NASA’s Marshall Space Flight Center. This science instrument will operate daily during the cruise phase as the landing date draws closer. The radio beacon is designed to support precise geolocation and navigation observations to orbiters, landers, and surface personnel, digitally confirming their positions on the Moon relative to other craft, ground stations, or rovers on the move. The check-out helps prepare to land on the Moon as the navigation demonstrator aims to gather this data throughout the duration of the surface operations phase of the mission. Flight controllers will analyze the data from this procedure to inform preparations for landing Feb. 22.

Rocket Propellant Tanks for NASA’s Artemis III Mission Take Shape

With the liquid oxygen tank now fully welded, all the major structures that will form the core stage for NASA’s SLS (Space Launch System) rocket for the agency’s Artemis III mission are ready for additional outfitting.

The hardware will be a part of the rocket used for the first of the Artemis missions planning to land astronauts on the Moon’s surface near the lunar South Pole. Technicians finished welding the 51-foot liquid oxygen tank structure inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility on Jan. 8.

The mega rocket’s other giant propellant tank – the liquid hydrogen tank – is already one fully welded structure. NASA and Boeing, the SLS core stage lead contractor, are currently priming the tank in another cell within the Vertical Assembly Building area called the Building 131 cryogenic tank thermal protection system and primer application complex. It completed internal cleaning Nov. 14.

Manufacturing hardware is a multi-step process that includes welding, washing, and, later, outfitting hardware. The internal cleaning process is similar to a shower to ensure contaminants do not find their way into the stage’s complex propulsion and engine systems prior to priming. Once internal cleaning is complete, primer is applied to the external portions of the tank’s barrel section and domes by an automated robotic tool. Following primer, technicians apply a foam-based thermal protection system to shield it from the extreme temperatures it will face during launch and flight while also regulating the super-chilled propellant within.

“NASA and its partners are processing major hardware elements at Michoud for several SLS rockets in parallel to support the agency’s Artemis campaign,” said Chad Bryant, acting manager of the Stages Office for NASA’s SLS Program. “With the Artemis II core stage nearing completion, the major structural elements of the SLS core stage for Artemis III will advance through production on the factory floor.”

The two massive propellant tanks for the rocket collectively hold more than 733,000 gallons of super-chilled propellant. The propellant powers the four RS-25 engines and must stay extremely cold to remain liquid.

The core stage, along with the RS-25 engines, will produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis III. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Through Artemis, NASA will send astronauts – including the first woman, first person of color, and first international partner astronaut – to explore the Moon for scientific discovery, economic benefits, and to build the foundation for crewed mission to Mars. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, exploration ground systems, advanced spacesuits and rovers, Gateway, and human landing systems.

Artemis II Mission Manager: Matthew Ramsey

Matthew Ramsey is keenly aware of the responsibility he shoulders to ensure NASA’s missions to the Moon are safe and successful. As the mission manager for Artemis II, NASA’s first crewed mission under Artemis, Ramsey is charged with helping to define the requirements and priorities for the missions and certifying that the hardware and operations needed to support flight are ready.

“For me, it’s all about the crew and ensuring their safety as they venture to the Moon and come home,” Ramsey said. “Sending people thousands of miles from home and doing it in a way that sets the stage for long-term exploration and scientific discovery is an incredibly complex task.”

Matthew Ramsey poses for a photo in front of a model of the SLS rocket. He is wearing a grey suit, light blue shift and a red and black patterned tie.

During the leadup to Artemis II, Ramsey is responsible for oversight of the daily preparations as NASA prepares to launch and fly the agency’s SLS (Space Launch System) rocket with a crew of four inside the Orion spacecraft. He will adjudicate issues that arise in the weeks and months ahead of the flight test and serve as deputy of the Mission Management Team – a tiger team that forms two days before launch to accept the risks associated with the mission and make decisions during the flight to address any changes or concerns.

A native of Hernando, Mississippi, Ramsey pitched for the Mississippi State University baseball team before earning bachelor’s and master’s degrees in aerospace engineering from the school.

“There are a lot of similarities between mission management and pitching,” he said. “You control many aspects of the tempo, and there’s a lot of weight on your shoulders.”

Ramsey began his career in the intelligence and defense sectors before joining the space agency in 2002 to work on guidance, navigation, and control for the X-37 Approach and Landing Test Vehicle. Later, he worked on the design of the Ares I and V rockets as part of NASA’s Constellation Program before transitioning in 2010 to the SLS Program in support of the chief engineer at the agency’s Marshall Space Flight Center.

During the Artemis I launch, Ramsey was the SLS Engineering Support Center manager at Marshall, coordinating across engineering teams to provide data and solutions to issues encountered during the multiple launch attempts. He then supported the Mission Management Team during Artemis I in an observational role, preparing for his position as Artemis II mission manager.

While NASA and its partners are preparing for Artemis II, work toward other Artemis missions is also underway. Ramsey also will serve as the mission manager for Artemis IV, the first Gateway assembly mission that also will include a lunar landing.

“With Artemis II on the horizon, most of my time is focused on making sure we’re ready to fly Reid, Victor, Christina, and Jeremy around the Moon and bring them safely home,” Ramsey said. “For Artemis IV, we’re in the mission concept-planning phase, establishing mission priorities and objectives and defining how we’ll transfer crew between all the hardware elements involved.”

As Artemis II nears, Ramsey is blending his operational experience and expertise in design, development, testing, and evaluation so that NASA is primed for what lies ahead: sending humans back to the Moon for the first time in more than 50 years and laying the foundation for future missions that will ultimately enable human exploration of Mars.

Teams Add Iconic NASA ‘Worm’ Logo to Artemis II Rocket, Spacecraft

Art and science merged as teams added the NASA “worm” logo on the SLS (Space Launch System) solid rocket boosters and the Orion spacecraft’s crew module adapter at NASA’s Kennedy Space Center for the agency’s Artemis II mission.

The iconic logo was introduced in 1975 by the firm of Danne & Blackburn as a modern emblem for the agency. It emerged from a nearly 30-year retirement in 2020 for limited use on select missions and products.

microsoftteams-image-2-rotated.jpg?w=136
Workers with NASA’s Exploration Ground Systems paint the bright red NASA “worm” logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility at the agency’s Kennedy Space Center on Jan. 30. The Exploration Ground Systems team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design.
NASA/Glenn Benson

NASA’s Exploration Ground Systems and prime contractor Jacobs began painting the red logotype onto the segments that form the Moon rocket’s two solid rocket boosters Jan. 22. To do so, crews used a laser projector to first mark off the location of the logo with tape, then applied two coats of paint and finished by adding several coats of clear primer. Each letter of the worm logo measures approximately 6 feet and 10 inches in height and altogether, stretches 25 feet from end to end, or a little less than the length of one of the rocket’s booster motor segments.

The location of the worm logo will be moderately different from where it was during Artemis I. While it will still be located on each of the rocket’s 17 story boosters, the modernist logo will be placed toward the front of the booster systems tunnel cover. The SLS boosters are the largest, most powerful solid propellant boosters ever flown and provide more than 75% of the thrust at launch.

Around the corner inside the Neil Armstrong Operations and Checkout Building at Kennedy, personnel adhered the worm logo and ESA (European Space Agency) insignia Jan. 28 on the spacecraft’s crew module adapter. The adapter houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the main modules.

In October 2023, technicians joined the crew and service modules together. The crew module will house the four astronauts as they journey around the Moon and back to Earth on an approximately 10-day journey. The spacecraft’s service module, provided by ESA, will supply the vehicle with electricity, propulsion, thermal control, air, and water in space.

NASA is working to land the first woman, first person of color, and first international partner astronaut on the Moon through Artemis. SLS and the Orion spacecraft are central to NASA’s deep space exploration plans, along with advanced spacesuits and rovers, the Gateway space station planned for orbit around the Moon, and commercial human landing systems.

Chandra: Black Hole Fashions Stellar Beads on A String

Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.”

SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. At the center of SDSS J1531, which is located about 3.8 billion light-years away, two of the cluster’s largest galaxies are colliding with each other.

Galaxy cluster SDSS J1531+3414
SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. In the heart of SDSS J1531, two of the cluster’s largest galaxies are colliding with each other. Surrounding these merging giants is a set of 19 large clusters of stars, called superclusters, arranged in an ‘S’ formation that resembles beads on a string.

Astronomers used several telescopes to study SDSS J1531 including NASA’s Chandra X-ray Observatory, and LOFAR (Low Frequency Array), a radio telescope. A composite image shows SDSS J1531 in X-rays from Chandra (blue and purple) that have been combined with radio data from LOFAR (dark pink) as well as an optical image from the Hubble Space Telescope (appearing as yellow and white). The inset gives a close-in view of the center of SDSS J1531 in optical light, showing the two large galaxies and a set of 19 large clusters of stars, called superclusters, stretching across the middle. The image shows these star clusters are arranged in an ‘S’ formation that resembles beads on a string.

The multiwavelength data provides signs of an ancient, titanic eruption in SDSS J1531, which a team of researchers think was responsible for creation of the 19 star clusters. Their argument is that an extremely powerful jet from the supermassive black holes in the center of one of the large galaxies pushed the surrounding hot gas away from the black hole, creating a gigantic cavity. The evidence for a cavity comes from “wings” of bright X-ray emission, seen with Chandra, tracing dense gas near the center of SDSS J1531. These wings are the edge of the cavity and the less dense gas in between is part of the cavity. LOFAR shows radio waves from the remains of the jet’s energetic particles filling in the giant cavity. These features are highlighted in a labeled version of the image.

The astronomers also discovered cold and warm gas located near the opening of the cavity, detected with the Atacama Large Millimeter and submillimeter Array and the Gemini North Telescope, respectively. A separate graphic shows the optical image with the cold gas added in green (left), and the warm gas added in red (right). The team argues that some of the hot gas pushed away from the black hole eventually cooled to form the cold and warm gas shown. The team thinks tidal effects from the two merging galaxies compressed the gas along curved paths, leading to the star clusters forming in the “beads on a string” pattern.

A paper led by Osase Omoruyi of the Center for Astrophysics | Harvard & Smithsonian (CfA) describing these results has recently been published in The Astrophysical Journal and is available online here. The authors of the paper are Grant Tremblay (CfA), Francoise Combes (Paris Observatory, France), Timothy Davis (Cardiff University, UK), Michael Gladders (University of Chicago), Alexey Vikhlinin (CfA), Paul Nulsen (CfA), Preeti Kharb (National Centre for Radio Astrophysics – Tata Institute of Fundamental Research, India), Stefi Baum (University of Manitoba, Canada), Christopher O’Dea (University of Manitoba, Canada), Keren Sharon (University of Michigan), Bryan Terrazas (Columbia University), Rebecca Nevin (Fermi National Accelerator Laboratory), Aimee Schechter (University of Colorado Boulder), John ZuHone (CfA), Michael McDonald (Massachusetts Institute of Technology), Hakon Dahle (University of Oslo, Norway), Matthew B.

New Horizons Detects Dusty Hints of Extended Kuiper Belt

New observations from NASA’s New Horizons spacecraft hint that the Kuiper Belt – the vast, distant outer zone of our solar system populated by hundreds of thousands of icy, rocky planetary building blocks – might stretch much farther out than we thought.

Speeding through the outer edges of the Kuiper Belt, almost 60 times farther from the Sun than Earth, the New Horizons SDC (Venetia Burney Student Dust Counter) instrument is detecting higher than expected levels of dust – the tiny frozen remnants of collisions between larger Kuiper Belt objects, or KBOs, and particles kicked up from KBOs being peppered by microscopic dust impactors from outside of the solar system.

The readings defy scientific models that the KBO population and density of dust should start to decline a billion miles inside that distance and contribute to a growing body of evidence that suggests the outer edge of the main Kuiper Belt could extend billions of miles farther than current estimates – or that there could even be a second belt beyond the one we already know.

The results appear in the Feb. 1 issue of the Astrophysical Journal Letters.

“New Horizons is making the first direct measurements of interplanetary dust far beyond Neptune and Pluto, so every observation could lead to a discovery,” said Alex Doner, lead author of the paper and a physics graduate student at the University of Colorado Boulder who serves as SDC lead. “The idea that we might have detected an extended Kuiper Belt – with a whole new population of objects colliding and producing more dust – offers another clue in solving the mysteries of the solar system’s most distant regions.”

Designed and built by students at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder under the guidance of professional engineers, SDC has detected microscopic dust grains produced by collisions among asteroids, comets and Kuiper Belt objects all along New Horizons’ 5-billion-mile, 18-year journey across our solar system – which after launch in 2006 included historic flybys of Pluto in 2015 and the KBO Arrokoth in 2019. The first science instrument on a NASA planetary mission to be designed, built and “flown” by students, the SDC counts and measures the sizes of dust particles, producing information on the collision rates of such bodies in the outer solar system.

The latest, surprising results were compiled over three years as New Horizons traveled from 45 to 55 AU (astronomical units from the Sun – with one AU being the distance between Earth and Sun, about 93 million miles.

These readings come as New Horizons scientists, using observatories like the Japanese Subaru Telescope in Hawaii, have also discovered a number KBOs far beyond the traditional outer edge of the Kuiper Belt. This outer edge (where the density of objects starts to decline) was thought to be at about 50 AU, but new evidence suggests the belt may extend to 80 AU, or farther. 

As telescope observations continue, Doner said, scientists are looking at other possible reasons for the high SDC dust readings. One possibility, perhaps less likely, is radiation pressure and other factors pushing dust created in the inner Kuiper Belt out past 50 AU. New Horizons could also have encountered shorter-lived ice particles that cannot reach the inner parts of the solar system and were not yet accounted for in the current models of the Kuiper Belt.

“These new scientific results from New Horizons may be the first time that any spacecraft has discovered a new population of bodies in our solar system,” said Alan Stern, New Horizons principal investigator from the Southwest Research Institute in Boulder. “I can’t wait to see how much farther out these elevated Kuiper Belt dust levels go.”

Now into its second extended mission, New Horizons is expected to have sufficient propellant and power to operate through the 2040s, at distances beyond 100 AU from the Sun. That far out, mission scientists say, the SDC could potentially even record the spacecraft’s transition into a region where interstellar particles dominate the dust environment. With complementary telescopic observations of the Kuiper Belt from Earth, New Horizons, as the only spacecraft operating in and collecting new information about the Kuiper Belt, has a unique opportunity to learn more about KBOs, dust sources and expanse of the belt, and interstellar dust and the dust disks around other stars.

The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. Southwest Research Institute, based in San Antonio and Boulder, Colorado, directs the mission via Principal Investigator Alan Stern and leads the science team, payload operations and encounter science planning. New Horizons is part of NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center.

      Gator Speaks
      The news in September about the historic NASA Stennis ASTRA (Autonomous Satellite Technology for Resilient Applications) payload mission brings wonderful encouragement to this ‘ol Gator!
      Gator SpeaksNASA/Stennis I know great potential when I see it, and the continuation of the center’s first-ever in-space autonomous systems payload mission aboard an orbiting satellite with Sidus Space, Inc. has just that.
      The historic mission highlights the can-do attitude shared by all at NASA Stennis.
      The center has a storied history of pushing the boundaries for what is possible. If there is a way to get something done, the folks at NASA Stennis will discover it.
      ASTRA is no different and represents a first in this particular space (pun intended!) of autonomous systems work at NASA Stennis.
      This is a first step toward fulfilling part of the center’s strategic plan to design autonomous systems to help accelerate the development of intelligent aerospace systems and services for government and industry.
      Such work could contribute to enhanced efficiency, improved safety, scalability to meet demands, and much more. The potential is ASTRA-nomical. See what I did there?
      Potential is not developed over night, which makes ASTRA even more intriguing. The mission could run for up to four years while gathering valuable data along the way.
      The ASTRA mission is an exciting leap forward for NASA Stennis to learn what is possible and perhaps open doors for a future that unlocks new frontiers.
      One thing this Gator has learned to be true is the brighter the future, the more we must believe in ourselves, and I believe in the NASA Stennis Autonomous Systems Laboratory team.

      Looking Back: A First for Women in Space
      Forty years ago this month, NASA demonstrated in real time that there is space for everybody. An image from Oct. 11, 1984, shows astronaut Kathryn D. Sullivan checking the latch of an antenna in the space shuttle Challenger’s open cargo during her historic extravehicular activity (spacewalk). The 13th flight of the Space Shuttle Program, STS-41G, was the first flight to include two women, Sullivan and Sally Ride. Ride has become the first American woman to fly to space in June 1983. A little more than a year later, Sullivan became the first American woman to walk in space. NASA’s Stennis Space Center near Bay St. Louis, Mississippi, tested space shuttle main engines for 34 years, from 1975 to 2009. The testing included hot fires of the flight engines that helped power this historic moment. To honor this time in space history, watch Space for Women on the agency’s new streaming platform – NASA+. The film features interviews with NASA employees and shows the variety of positions held by women in the agency.NASA The official portrait of Astronaut Kathryn D. Sullivan from 1984.

      The Fabric of Marshall: Center Hosts Safety Day 2024
      By Serena Whitfield
      “Safety Woven Throughout the Fabric of Marshall” was the theme for Safety Day at NASA’s Marshall Space Flight Center on Sept. 26.
      Kickoff activities were held in Building 4316 and other sites around the center.
      “It is crucial to ensure that each of us weaves safety into everything we do, not only at work, but in our daily lives,” Marshall Director Joseph Pelfrey said.
      NASA Marshall Space Flight Center Director Joseph Pelfrey, left, with NASA astronaut Mark T. Vande Hei, who was the keynote speaker for Marshall’s Safety Day on Sept. 26. NASA/Krisdon Manecke NASA started the Safety Day tradition following the space shuttle Columbia accident in 2003. Centers across the agency dedicate a day each year for team members to pause and reflect on keeping the work environment safe. 
      This year’s Safety Day began with a breakfast for employees, which was sponsored by Jacobs and Bastion Technologies. After breakfast, Bill Hill, director of the Safety and Mission Assurance Directorate at Marshall, welcomed center team members before introducing Pelfrey.
      “Over the past year, Marshall’s leadership and workforce have highlighted that transparency is an essential cultural attribute of our workforce and center,” Pelfrey said. “It is also important to our core value of safety. Transparency fosters an environment where employees feel comfortable in reporting potential risks or safety concerns without fear of retribution. This openness ensures that issues are addressed early. It builds trust and accountability within our workforce, center, NASA, and external stakeholders.”
      NASA astronaut Mark T. Vande Hei talks about his time in space aboard the International Space Station. NASA/Krisdon Manecke Guest speaker Marceleus Venable, a purpose coach, trainer, and author, followed Pelfrey’s remarks, telling team members to be safe by taking care of their physical and mental health. He encouraged them to take the time to pat themselves on the back for all their hard work and to appreciate their fellow workers at Marshall.
      NASA astronaut Mark T. Vande Hei was the keynote speaker, encouraging employees to be team players in NASA’s safety mission.
      “We need a lot of talented team players to meet the challenges that we have for future space flights,” said Vande Hei, who was selected as a NASA astronaut in 2009 and most recently served as a flight engineer on the International Space Station as part of Expedition 65 and 66. “Always try to do your best, but make sure that other people around you are doing their best as well and help them do that rather than you standing out as always being the best.”
      Peter Wreschinsky, second from left, a Jacobs Space Exploration Group employee, is presented with the Golden Eagle Award during Safety Day. He is joined by his wife, Terri. They are joined by Bill Hill, left, director of the Safety and Mission Assurance Directorate at Marshall, and Jeff Haars, right, Jacobs vice president. The Golden Eagle Award is a part of the Mission Success is in Our Hands initiative, a collaboration between Marshall and Jacobs. Wreschinsky was recognized with the award for voicing concern about a valve impacted by corrosion on the Commercial Crew Program Crew-8 Dragon Capsule. The valve and several others were subsequently replaced. NASA/Serena Whitfield Micah Embry, the Safety Day 2024 chairperson, presented Vande Hei with a certificate for his participation. 
      Also during the event, Hill awarded the Golden Eagle Award to Peter Wreschinsky, a Jacobs Space Exploration Group employee. The award is part of the Mission Success is in Our Hands safety initiative, a collaboration between Marshall and Jacobs.
      More than 400 civil servants and contractors participated in Safety Day, with organizational and vender booths providing information to employees across a variety of safety topics, including Emergency Management Services, fire protection, storm shelters, and more.
      “As Marshall continues to be a leader at NASA and across the aerospace industry, … we must always be looking forward to improve our procedures and anticipate potential hazards,” Pelfrey said. “Safety is directly tied to our mission success. Without safety, we cannot achieve the goals we set for ourselves in space exploration, research, and innovation.”

      Human Lander System Spotlight: Preparing for the First Crewed Lunar Landings for Artemis
      The featured business unit for the month of September at NASA’s Marshall Space Flight Center was Lander Systems. Marshall leads the development of the systems needed to safely land humans on the Moon and, eventually Mars. This includes the Human Landing System Program (HLS), which manages the development of commercial lunar landing systems that will transport astronauts to and from the surface of the Moon as part of the agency’s Artemis campaign.
      For Artemis III and Artemis IV, NASA has selected SpaceX’s Starship HLS, while Blue Origin’s Blue Moon lander will be used for Artemis V. Having two distinct lunar lander designs, with different approaches to how they meet NASA’s mission needs, provides more robustness while ensuring a regular cadence of Moon landings.
      NASA works closely with its industry partners to mature the landers, exercising insight and offering collaboration to ensure astronaut safety and mission success. Through Artemis, NASA aims to land the first woman, first person of color, and first international partner astronaut on the lunar surface while advancing key science and discovery for the benefit of all.
      Learn more about HLS and meet some of the NASA Marshall teammates below who are working on the lunar landers:
      Amy BuckNASA/Ken Hall Amy Buck has been working with Artemis systems since she first came to Marshall 10 years ago. Previously part of the cryogenic insulation team for the SLS (Space Launch System) rocket, Buck is now the materials discipline lead for HLS. In her role, she has the chance to work on nearly every piece of hardware for the two landers as she and her team work with each of the HLS providers to ensure compliance with NASA’s requirements.
      “The NASA HLS materials team is vital in supporting the design, testing, and manufacturing of the landers,” Buck said. “Landing on the Moon is central to the larger Artemis mission, and I’m super excited to be part of the Artemis Generation.”
      Buck is most excited to see the first woman land on the Moon under Artemis and says she hopes it will inspire young girls – the next generation of engineers and scientists – to go into science and engineering.
      Sean UnderwoodNASA/Ken Hall Mission success is all in the details for Sean Underwood, the thermal discipline lead for HLS. The Georgia native works with a team responsible for ensuring that the lunar landers can operate in the Moon’s harsh environment.
      “There are unique thermal challenges associated with the Artemis III, IV, and V missions,” Underwood said. “Our primary objective is to manage thermal energy and heating rates, ensuring that HLS components and systems remain within thermal limits across all mission environments.”
      Underwood joined Marshall in 2020 and sees his role with Artemis as one that will shape the future of space exploration – and Marshall. “Marshall Space Flight Center has been at the forefront of monumental space projects since its inception,” he said. “Through Artemis, we are ensuring that the legacy of past missions continues to inspire and drive us forward.”

      Innovative Thermal Energy Storage Tanks Keep Marshall Cool – and Save Taxpayer Dollars
      By Rick Smith
      As any home or business owner in the Southern United States knows, maintaining energy costs while trying to keep cool in the sweltering summer months is no simple challenge.
      But one “cool” new infrastructure upgrade at NASA’s Marshall Space Flight Center will reduce the center’s utility costs by approximately $250,000 a year, shrinking Marshall’s environmental footprint and streamlining long-term infrastructure maintenance costs.
      NASA Marshall Space Flight Center facilities engineers Connor McLean, left, and Angela Bell assess the readiness of Marshall’s new thermal energy storage tank, which officially goes into operation in October. The tank stands alongside Marshall’s original thermal tank outside Building 4473, where they chill and store water to cool off laboratories, offices, and other buildings during the hot summer months. McLean and Bell lead the tank project on behalf of Marshall’s Office of Center Operations. NASA/Charles Beason It’s called a thermal energy storage tank – 60 feet high, 60 feet in diameter, each unit capable of holding approximately 1.125 million gallons of chilled water – and it represents another milestone for facilities engineers in Marshall’s Office of Center Operations, whose tactics have already reduced center-wide energy expenditure by a dizzying 58.3% since fiscal year 2003.
      Thermal energy storage is not a new process; it’s been used for decades to maximize efficiency in temperature control, particularly among industrial facilities and large public venues from hospitals to indoor stadiums. At Marshall, the chilled water serves a critical purpose center-wide, circulating from a central plant via a network of underground pipes to help keep laboratories and other buildings temperate throughout the summer heat.
      “The average team member might not realize it’s chilled water, not just air, that keeps our labs, offices, and test facilities cool,” said Marshall facilities engineer Angela Bell, who helped oversee the installation of the second tank. “Our tanks operate at night, when utility prices drop and there is less overall demand on the regional energy grid, then send the chillwater out during the day.”
      Marshall’s first tank was built and put into operation in 2008-2009. The second officially goes into service in October, joining its counterpart in creating chilled water overnight. Together, the tanks – situated adjacent to Building 4473 on the corner of Morris and Titan roads – provide an annual energy savings of roughly half a million dollars.
      Marshall facilities engineer Connor McLean, who succeeded Bell as project manager for the new tank, noted that each thermal energy storage tank handles approximately 106,000 kilo-BTUs worth of cooling activity per day – or roughly 1,750 times as much cooling capacity as a central air system in a traditional family home.
      Even with that considerable output, Marshall’s original tank had been hard-pressed to keep up with demand across the entire center over the past decade and a half, as climate change steadily pushed temperatures to sustained extremes.
      “This is a huge stride in critical system redundancy,” McLean said. “Having the second tank enables us to run both concurrently or give one of them some necessary downtime without loss of center-wide functionality. That added capability makes Marshall more resilient and bolsters our confidence in our ability to handle unforeseen challenges.”
      The electricity that powers the storage tanks is a mix – hydroelectric, fossil fuels, nuclear, and an increasing amount of renewable energy sources – provided by the Tennessee Valley Authority via the U.S. Army, from whom NASA leases property on Redstone Arsenal. 
      “The tanks will be tremendous cost-savers for the next 40-50 years,” Bell said. “They allow us to use energy much more efficiently, based on past energy consumption levels – and that allows Marshall to do other things with those dollars.”
      Over the past 20 years, Marshall has reinvested energy savings and facilities cost underruns back into center operations, often to fund new, cost-saving overhauls: upgrading facility HVAC systems or replacing obsolete lighting with more efficient LEDs.
      “If we didn’t reduce consumption, our projected utility costs would be around $30 million per year,” said Rhonda Truitt, Marshall’s energy and water manager. “Thanks to efficient strategizing, encouraged and championed by Marshall and NASA leadership, we typically operate in the range of just $16-18 million per year.”
      Such strategies have enabled Marshall to effectively keep its infrastructure budget flat since the early 2010s – reducing overall energy consumption and replacing outdated facilities with more cost-conscious, environmentally friendly modern buildings, a program known among facilities engineers as “repair by replacement.”
      The U.S. Army at Redstone doesn’t employ a central chiller plant of its own, but the Marshall facilities team works “very closely” with their counterparts on the military side.
      “We have a great working relationship,” Truitt said. “The real advantage of our system is that by reducing our peak energy demand, it reduces it for all of Redstone – which benefits the rest of the Arsenal and the lower Tennessee Valley.”
      The new tank goes into operation just in time for the start of National Energy Awareness Month in October – and Truitt and her team encourage the Marshall workforce to continue to practice sensible energy conservation tactics even as sweat-inducing temperatures subside.
      “Turn off lights and computer monitors wherever possible, don’t leave doors or windows propped open, and be mindful of all the small things that can add up over time,” Truitt said. “Our goal is always to help team members do their jobs in the most efficient way possible, to accomplish Marshall’s objectives and conserve our energy budget without impeding the mission.”
      Thanks to the center’s new thermal energy storage tank, that should be no sweat.

      Keeping the Pace: Marshall Hosts Annual ‘Racin’ the Station’ Duathlon
      A costumed gorilla pacer leads a group of runners during “Racin’ the Station” duathlon, a run/bike/run event where the participants “raced” the International Space Station. The event was Sept. 28 at NASA’s Marshall Space Flight Center, which is on Redstone Arsenal. “Racin’ the Station” is an annual event where participants try to complete the course faster than it takes the space station to complete one Earth orbit, which is every 91 minutes, 12 seconds. Organizers track the starting location of the space station at the race start, and a costumed pacer keeps up with the station time on the course as a visual marker for participants to stay ahead of.  Before the race, organizers drew a to-scale SLS (Space Launch System) Block 1 rocket in chalk onto the Activities Building parking lot near the race transition area. The opening ceremonies featured a video of the Artemis 1 launch, with the race starting with the launch of a model rocket. “The rain was a first for race day since we started this event in 2012,” said Kent Criswell, race organizer for Marshall. “But we still had a safe race with 106 individuals and 13 relay teams finishing.” The event is organized by the Team Rocket Triathlon Club in Huntsville and by the Marshall Association, a professional employee service organization at the Marshall Center whose members include civil service employees, retirees and contractors. Proceeds from the registration fee for the event go to the Marshall Association scholarship fund. Race results can be found here. (NASA/Charles Beason)

      NASA Seeks Innovators for Lunar Waste Competition 
      By Savannah Bullard 
      A new NASA competition, the LunaRecycle Challenge, is open and offering $3 million in prizes for innovations in recycling material waste on deep space missions. 
      As NASA continues efforts toward long-duration human space travel, including building a sustained human presence on the Moon through its Artemis missions, the agency needs novel solutions for processing inorganic waste streams like food packaging, discarded clothing, and science experiment materials. While previous efforts focused on the reduction of trash mass and volume, this challenge will prioritize technologies for recycling waste into usable products needed for off-planet science and exploration activities.  
      NASA’s LunaRecycle Challenge will incentivize the design and development of energy-efficient, low-mass, and low-impact recycling solutions that address physical waste streams and improve the sustainability of longer-duration lunar missions. Through the power of open innovation, which draws on the public’s ingenuity and creativity to find solutions, NASA can restructure the agency’s approach to waste management, support the future of space travel, and revolutionize waste treatments on Earth, leading to greater sustainability on our home planet and beyond. 
      “Operating sustainably is an important consideration for NASA as we make discoveries and conduct research both away from home and on Earth,” said Amy Kaminski, program executive for NASA’s Prizes, Challenges, and Crowdsourcing program. “With this challenge, we are seeking the public’s innovative approaches to waste management on the Moon and aim to take lessons learned back to Earth for the benefit of all.” 
      NASA’s LunaRecycle Challenge will offer two competition tracks: a Prototype Build track and a Digital Twin track. The Prototype Build Track focuses on designing and developing hardware components and systems for recycling one or more solid waste streams on the lunar surface. The Digital Twin Track focuses on designing a virtual replica of a complete system for recycling solid waste streams on the lunar surface and manufacturing end products. Offering a Digital Twin track further lowers the barrier of entry for global solvers to participate in NASA Centennial Challenges and contribute to agency missions and initiatives.  
      Teams will have the opportunity to compete in either or both competition tracks, each of which will carry its own share of the prize purse. 
      The LunaRecycle Challenge also will address some of the aerospace community’s top technical challenges. In July, NASA’s Space Technology Mission Directorate released a ranked list of 187 technology areas requiring further development to meet future exploration, science, and other mission needs. The results integrated inputs from NASA mission directorates and centers, industry organizations, government agencies, academia, and other interested individuals to help guide NASA’s space technology development and investments. This list and subsequent updates will help inform future Centennial Challenges.  
      The three technological needs that LunaRecycle will address include logistics tracking, clothing, and trash management for habitation; in-space and on-surface manufacturing of parts and products; and in-space and on-surface manufacturing from recycled and reused materials. 
      “I am pleased that NASA’s LunaRecycle Challenge will contribute to solutions pertaining to technological needs within advanced manufacturing and habitats,” said Kim Krome, acting program manager for agency’s Centennial Challenges, and challenge manager of LunaRecycle. “We are very excited to see what solutions our global competitors generate, and we are eager for this challenge to serve as a positive catalyst for bringing the agency, and humanity, closer to exploring worlds beyond our own.” 
      NASA has contracted The University of Alabama to be the allied partner for the duration of the challenge. The university, based in Tuscaloosa, Alabama, will coordinate with former Centennial Challenge winner AI Spacefactory to facilitate the challenge and manage its competitors.  
      To register as a participant in NASA’s LunaRecycle Challenge, visit: lunarecyclechallenge.ua.edu. 
      NASA’s LunaRecycle Challenge is led by the agency’s Kennedy Space Center with support from Marshall Space Flight Center. The competition is a NASA’s Centennial Challenge, based at Marshall. Centennial Challenges are part of NASA’s Prizes, Challenges, and Crowdsourcing program within the agency’s Space Technology Mission Directorate.

      Fueling Complete on Europa Clipper Spacecraft
      Technicians completed loading propellants in the agency’s Europa Clipper spacecraft Sept. 22, inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center.
      Technicians work to complete operations prior to propellant load for NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center on Sept. 11.NASA/Kim Shiflett Housed in the largest spacecraft NASA has ever built for a planetary mission, Europa Clipper’s propulsion module is an aluminum cylinder 10 feet long and 5 feet wide, and it holds the spacecraft’s array of 24 engines and 6067.6 pounds of propellant in two propulsion tanks, as well as the spacecraft’s helium pressurant tanks. The fuel and oxidizer held by the tanks will flow to the 24 engines, creating a controlled chemical reaction to produce thrust in space during its journey to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.
      After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.
      NASA is targeting launch Oct. 10 aboard a Space X Falcon Heavy rocket from NASA Kennedy’s historic Launch Complex 39A.
      Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate. The main spacecraft body was designed by APL in collaboration with NASA JPL and NASA’s Goddard Space Flight Center. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.

      Skywatching Home What’s Up: October 2024… Skywatching Skywatching Home Eclipses What’s Up Explore the Night Sky Night Sky Network More Tips and Guides FAQ   Comets: Unpredictable, But Irresistible
      A new comet is passing through the inner solar system! Time will tell if it’s the brightest of the year, once it appears in twilight after about October 14.
      Skywatching Highlights
      All month – Planet visibility report: Look for Venus low in the west just after sunset; Saturn can be seen toward the southeast as soon as it gets dark; Mars rises around midnight; and Jupiter rises in the first half of the night (rising earlier as the month goes on). October 2 – New moon October 11 – Europa is easily observable to one side of Jupiter by itself this morning using binoculars. October 14-31 – Comet C/2023 A3 (Tsuchinshan-ATLAS) becomes visible low in the west following sunset. If the comet’s tail is well-illuminated by sunlight, it could be visible to the unaided eye. The first week and a half (Oct. 14-24) is the best time to observe, using binoculars or a small telescope. October 13-14 – After dark both nights, look for the nearly full Moon with Saturn toward the southeast. October 17 – Full moon October 20 – The Moon rises near Jupiter, with the giant planet looking extremely bright. You should be able to find them low in the east after around 10 pm. October 23-24 – Early risers will be able to spot Mars together with the Moon, high overhead in the south both mornings. October 25 – Europa is easily observable to one side of Jupiter by itself this morning using binoculars. Transcript
      What’s Up for October?
      This month’s viewing tips for Venus, Saturn, Mars and Jupiter. When’s the best time to observe the destination of NASA’s next deep space mission? And how you can see a (potentially bright) comet this month?
      And watch our video ’till the end for photos of highlights from last month’s skies.
      Sky chart showing Mars near the Moon on October 23. The pair appear quite high overhead, along with Jupiter. NASA/JPL-Caltech Up first, we look at the visibility of the planets in October. Look for Venus low in the west just after sunset. It’s setting by the time the sky is fully dark. Saturn is visible toward the southeast as soon as it gets dark out, and sets by dawn. Mars rises around midnight all month. By dawn it has climbed quite high into the south-southeastern sky, appearing together with Jupiter. Now, Jupiter is rising in the first half of the night. In early October you’ll find it high in the south as dawn approaches, and later in the month it’s progressed farther over to the west before sunrise.
      And, speaking of Jupiter, NASA plans to launch its latest solar system exploration mission to one of the giant planet’s moons this month. Europa Clipper is slated to blast off as early as October 10th. It’s thought that Europa holds an enormous ocean of salty liquid water beneath its icy surface. That makes this the first mission dedicated to studying an ocean world beyond Earth. Europa Clipper is designed to help us understand whether this icy moon could support some form of life, and along the way it’ll teach us more about the conditions that make a world habitable.
      Now, if you’ve ever pointed binoculars or a telescope at Jupiter, you know the thrill of seeing the little star-like points of light next to it that are its four large moons, which were first observed by Galileo in 1610.
      There are two mornings in October, the 11th and the 25th, when you can most easily observe Europa. These are times when the moon is at its greatest separation from the planet as seen from here on Earth, and it’s all by itself to one side of Jupiter. So be sure to have your own peek at Jupiter’s moon Europa this month, as a new NASA mission begins its journey to explore an ocean in the sky.
      Now a look at Moon and planet pair-ups for October. On the 13th and 14th after dark, look for the nearly full Moon with Saturn toward the southeast. Then on the evening of October 20th, the Moon rises near Jupiter, with the giant planet looking extremely bright.
      You should be able to find them low in the east after around 10 pm that night. Then, in the morning of Oct. 23rd and 24th, early risers will be able to spot Mars together with the Moon, high overhead in the south.

NASA/JPL-Caltech October offers a chance to observe what could be the brightest comet of the year. Earlier this year we got a look at Comet 12P, which was visible with binoculars but not super bright. Now another of these ancient and icy dust balls is streaking through our neighborhood on an 80,000-year orbit from the distant reaches of the Oort Cloud. The comet, known as C/2023 A3, aka Tsuchinshan-ATLAS, is currently speeding through the inner solar system. It passed its closest to the Sun in late September, and will be at its closest to Earth on October 13th. And after that time, through the end of the month, will be the best time to look for it. This is when the comet will become visible low in the western sky beginning during twilight.
      It will quickly rise higher each subsequent evening, making it easier to observe, but it’ll also be getting a little fainter each night. As with all comets, predictions for how bright it could get are uncertain. If the comet’s tail is brilliantly illuminated by the Sun, predictions show that it could become bright enough to see with the unaided eye. But comets have a way of surprising us, so we’ll just have to wait and see.
      Your best shot at seeing it will be from around October 14th through the 24th, with binoculars or a small telescope, and a reasonably clear view toward the west. So good luck, and clear skies, comet hunters!
