Trailing Curiosity are the rover’s tracks, which can linger on the Martian surface for months before being erased by the wind. NASA/JPL-Caltech/University of Arizona The image marks what may be the first time one of the agency’s Mars orbiters has captured the rover driving. NASA’s Curiosity Mars rover has never been camera shy, having been seen in selfies and images taken from space. But on Feb. 28 — the 4,466th Martian day, or sol, of the mission — Curiosity was captured in what is believed to be the first orbital image of the rover mid-drive across the Red Planet. Taken by the HiRISE (High-Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter, the image shows Curiosity as a dark speck at the front of a long trail of rover tracks. Likely to last for months before being erased by wind, the tracks span about 1,050 feet (320 meters). They represent roughly 11 drives starting on Feb. 2 as Curiosity trucked along at a top speed of 0.1 mph (0.16 kph) from Gediz Vallis channel on the journey to its next science stop: a region with potential boxwork formations, possibly made by groundwater billions of years ago. How quickly the rover reaches the area depends on a number of factors, including how its software navigates the surface and how challenging the terrain is to climb. Engineers at NASA’s Jet Propulsion Laboratory in Southern California, which leads Curiosity’s mission, work with scientists to plan each day’s trek. “By comparing the time HiRISE took the image to the rover’s commands for the day, we can see it was nearly done with a 69-foot drive,” said Doug Ellison, Curiosity’s planning team chief at JPL. Designed to ensure the best spatial resolution, HiRISE takes an image with the majority of the scene in black and white and a strip of color down the middle. While the camera has captured Curiosity in color before, this time the rover happened to fall within the black-and-white part of the image. In the new image, Curiosity’s tracks lead to the base of a steep slope. The rover has since ascended that slope since then, and it is expected to reach its new science location within a month or so. More About Curiosity and MRO NASA’s Curiosity Mars rover was built at JPL, which is managed for the agency by Caltech in Pasadena, California. JPL manages both the Curiosity and Mars Reconnaissance Orbiter missions on behalf of NASA’s Science Mission Directorate in Washington as part of the agency’s Mars Exploration Program portfolio. The University of Arizona, in Tucson, operates HiRISE, which was built by BAE Systems in Boulder, Colorado.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) EnerVenue’s batteries don’t require energy-consuming temperature control or maintenance and can be stored anywhere, including in the company’s “EnerStation” battery station, pictured here.Credit: EnerVenue, Inc. Battery technology that has powered the International Space Station, the Hubble Space Telescope, and numerous satellites is now storing energy on Earth, enabling intermittent renewable energy sources to provide steady power. These extremely durable batteries were made more affordable for the average consumer by California-based EnerVenue Inc., which was able to bring down the cost of the technology by removing the need for expensive platinum, making terrestrial applications more feasible. With the cost-saving innovations, the batteries could be used for power plants, businesses, and homes. NASA first used nickel-hydrogen batteries in 1990 for the Hubble Space Telescope — the technology’s debut in low-Earth orbit on a major project. It was the primary power system for the International Space Station for more than 18 years before eventually being replaced by lithium-ion batteries. Each nickel-hydrogen cell consists of a nickel cathode — the positive electrode — and a hydrogen-catalyzed anode, which typically uses expensive platinum. Charging the battery generates hydrogen inside the highly pressurized vessel, which then gets reabsorbed on discharge. Dr. Yi Cui , EnerVenue Chief Technology Advisor, developed a technique to remove platinum from these batteries, dramatically reducing costs of technology that had grown more sophisticated over decades of NASA adapting it to high-level missions. Much of the groundwork for EnerVenue’s batteries was laid by NASA. Having laid the foundation and tested it in space, NASA paved the way for a durable power source that is now available for several applications on Earth.

The asteroid Donaldjohanson as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI). This is one of the most detailed images returned by NASA’s Lucy spacecraft during its flyby. This image was taken at 1:51 p.m. EDT (17:51 UTC), April 20, 2025, near closest approach, from a range of approximately 660 miles (1,100 km). The spacecraft’s closest approach distance was 600 miles (960 km), but the image shown was taken approximately 40 seconds beforehand. The image has been sharpened and processed to enhance contrast.NASA/Goddard/SwRI/Johns Hopkins APL/NOIRLab NASA’s Lucy spacecraft took this image of the main belt asteroid Donaldjohanson during its flyby on April 20, 2025, showing the elongated contact binary (an object formed when two smaller bodies collide). This was Lucy’s second flyby in the spacecraft’s 12-year mission. Launched on Oct. 16, 2021, Lucy is the first space mission sent to explore a diverse population of small bodies known as the Jupiter Trojan asteroids. These remnants of our early solar system are trapped on stable orbits associated with – but not close to – the giant planet Jupiter. Lucy will explore a record-breaking number of asteroids, flying by three asteroids in the solar system’s main asteroid belt, and by eight Trojan asteroids that share an orbit around the Sun with Jupiter. April 20, 2025 marked Lucy’s second flyby. The spacecraft’s next target is Trojan asteroid Eurybates and its satellite Queta in Aug. 2027. Lucy is named for a fossilized skeleton of a prehuman ancestor. This flyby marked the first time NASA sent a spacecraft to a planetary body named after a living person. Asteroid Donaldjohanson was unnamed before becoming a target. The name Donaldjohanson was chosen in honor of the paleoanthropologist who discovered the Lucy fossil, Dr. Donald Johanson.

NASA/JPL-Caltech Written by Susanne Schwenzer, Planetary Geologist at The Open University Earth planning date: Monday, 21st April 2025 It is Easter Monday, a bank holiday here in the United Kingdom. I am Science Operations Working Group Chair today, a role that is mainly focused on coordinating all the different planning activities on a given day, and ensuring all the numbers are communicated to everyone. And with that I mean making sure that everyone knows how much power we have and other housekeeping details. It’s a fun role, but on the more technical side of the mission, which means I don’t get to look at the rocks in the workspace as closely as my colleagues who are planning the activities of the instruments directly investigating the rocks. It’s a lot of fun to see how planning day after planning day things come together. But why am I doing this on a bank holiday, when I could well be on my sofa? I just was reminded in the hours before planning how much fun it actually is to spend a little more time looking at all the images – and not the usual hectic rush coming out of an almost complete work day (we start at 8 am PDT, which is 4 pm here in the UK!). So, I enjoyed the views of Mars, and I think Mars gave me a thumbs up for it, or better to say a little pointy ‘rock up’ in the middle of a sandy area, as you can see in the image above! I am sure you noticed that our team has a lot to celebrate! Less than a month after the publication about alkanes made headlines in many news outlets, we have another big discovery from our rover, now 4518 sols on Mars: in three drill holes, the rover instruments detected the mineral siderite, a carbonate. That allowed a group of scientists from our team to piece together the carbon cycle of Mars. If you want to know more, the full story is here. I am looking forward to our next big discovery. Who knows that that is? Well, it would not be exploration, if we knew! But today’s workspace looks intriguing with all its little laminae (the very fine layers) and its weathering patterns that look like a layered cake that little fingers have picked the icing off! (Maybe I had too many treats of the season this weekend? That’s for you to decide!) But then Mars did what it did so many times lately: we did not pass our slip risk assessment and therefore had to keep the arm stowed. I think there is a direct link between geologists getting exciting about all the many rocks, and a wheel ending up on one of them, making it unsafe to unstow the arm. There was a collective sigh of disappointment – and then we moved on to what we actually can do. And that is a lot of imaging. As exciting as getting an APXS measurement and MAHLI images would be, Mastcam images, ChemCam chemistry and RMI images are exciting, too. The plan starts with three Mastcam activities to document the small troughs that form around some of the rocks. Those amount to 15 frames already, then we have a ten-frame mosaic on a target called “West Fork,” which is looking at rocks in the middle ground of the scenery and display interesting layering. Finally, a 84 frame mosaic will image Texoli, one of the large buttes in our neighbourhood, in all its beauty. It shows a series of interesting layers and structures, including some that might be akin to what we expect the boxwork structures to look like. Now, did you keep count? Yes, that’s 109 frames from Mastcam – and add the one for the documentation of the LIBS target, too, and Mastcam takes exactly 110 frames! ChemCam is busy with a target called “Lake Poway,” which represents the bedrock around us. Also in the ChemCam activities is a long distance RMI upwards Mt Sharp to the Yardang unit. After the drive – more of that later – ChemCam as an automated observation, we call it AEGIS, where ChemCam uses a clever algorithm to pick its own target. The drive will be very special today. As you may have seen, we are imaging our wheels in regular intervals to make sure that we are keeping track of the wear and tear that over 34 km of offroad driving on Mars have caused. For that, we need a very flat area and our rover drivers did locate one due West of the current rover positions. So, that’s where we will drive first, do the full MAHLI wheel imaging and then return to the originally planned path. That’s where we’ll do a MARDI image, post drive imaging to prepare the planning for the next sols, and the above mentioned AEGIS. In addition to all the geologic investigations, there is continuous environmental monitoring ongoing. Curiosity will look at opacity and dust devils, and REMS will switch on regularly to measure wind speeds, humidity, temperature, ultraviolet radiation and pressure throughout the plan. Let’s not forget DAN, which monitors water and chlorine in the subsurface as we are driving along. It’s so easy to forget the ones that sit quietly in the back – but in this case, they have important data to contribute!

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s AVIRIS-3 airborne imaging spectrometer was used to map a wildfire near Cas-tleberry, Alabama, on March 19. Within minutes, the image was transmitted to firefighters on the ground, who used it to contain the blaze. NASA/JPL-Caltech, NASA Earth Observatory The map visualizes three wavelengths of infrared light, which are invisible to the human eye. Orange and red areas show cooler-burning areas, while yellow indicates the most intense flames. Burned areas show up as dark red or brown.NASA/JPL-Caltech, NASA Earth Observatory Data from the AVIRIS-3 sensor was recently used to create detailed fire maps in minutes, enabling firefighters in Alabama to limit the spread of wildfires and save buildings. A NASA sensor recently brought a new approach to battling wildfire, providing real-time data that helped firefighters in the field contain a blaze in Alabama. Called AVIRIS-3, which is short for Airborne Visible Infrared Imaging Spectrometer 3, the instrument detected a 120-acre fire on March 19 that had not yet been reported to officials. As AVIRIS-3 flew aboard a King Air B200 research plane over the fire about 3 miles (5 kilometers) east of Castleberry, Alabama, a scientist on the plane analyzed the data in real time and identified where the blaze was burning most intensely. The information was then sent via satellite internet to fire officials and researchers on the ground, who distributed images showing the fire’s perimeter to firefighters’ phones in the field. All told, the process from detection during the flyover to alert on handheld devices took a few minutes. In addition to pinpointing the location and extent of the fire, the data showed firefighters its perimeter, helping them gauge whether it was likely to spread and decide where to add personnel and equipment. As firefighters worked to prevent a wildfire near Perdido, Alabama, from reaching nearby buildings, they saw in an infrared fire map from NASA’s AVIRIS-3 sensor that showed the fire’s hot spot was inside its perimeter. With that intelligence, they shifted some resources to fires in nearby Mount Vernon.NASA/JPL-Caltech, NASA Earth Observatory “This is very agile science,” said Robert Green, the AVIRIS program’s principal investigator and a senior research scientist at NASA’s Jet Propulsion Laboratory in Southern California, noting AVIRIS-3 mapped the burn scar left near JPL by the Eaton Fire in January. Observing the ground from about 9,000 feet (3,000 meters) in altitude, AVIRIS-3 flew aboard several test flights over Alabama, Mississippi, Florida, and Texas for a NASA 2025 FireSense Airborne Campaign. Researchers flew in the second half of March to prepare for prescribed burn experiments that took place in the Geneva State Forest in Alabama on March 28 and at Fort Stewart-Hunter Army Airfield in Georgia from April 14 to 20. During the March span, the AVIRIS-3 team mapped at least 13 wildfires and prescribed burns, as well as dozens of small hot spots (places where heat is especially intense) — all in real time. At one of the Mount Vernon, Alabama, fires, firefighters used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings.NASA/JPL-Caltech, NASA Earth Observatory Data from imaging spectrometers like AVIRIS-3 typically takes days or weeks to be processed into highly detailed, multilayer image products used for research. By simplifying the calibration algorithms, researchers were able to process data on a computer aboard the plane in a fraction of the time it otherwise would have taken. Airborne satellite internet connectivity enabled the images to be distributed almost immediately, while the plane was still in flight, rather than after it landed. The AVIRIS team generated its first real-time products during a February campaign covering parts of Panama and Costa Rica, and they have continued to improve the process, automating the mapping steps aboard the plane. ‘Fan Favorite’ The AVIRIS-3 sensor belongs to a line of imaging spectrometers built at JPL since 1986. The instruments have been used to study a wide range of phenomena — including fire — by measuring sunlight reflecting from the planet’s surface. During the March flights, researchers created three types of maps. One, called the Fire Quicklook, combines brightness measurements at three wavelengths of infrared light, which is invisible to the human eye, to identify the relative intensity of burning. Orange and red areas on the Fire Quicklook map show cooler-burning areas, while yellow indicates the most intense flames. Previously burned areas show up as dark red or brown. Another map type, the Fire 2400 nm Quicklook, looks solely at infrared light at a wavelength of 2,400 nanometers. The images are particularly useful for seeing hot spots and the perimeters of fires, which show brightly against a red background. A third type of map, called just Quicklook, shows burned areas and smoke. The Fire 2400 nm Quicklook was the “fan favorite” among the fire crews, said Ethan Barrett, fire analyst for the Forest Protection Division of the Alabama Forestry Commission. Seeing the outline of a wildfire from above helped Alabama Forestry Commission firefighters determine where to send bulldozers to stop the spread. Additionally, FireSense personnel analyzed the AVIRIS-3 imagery to create digitized perimeters of the fires. This provided firefighters fast, comprehensive intelligence of the situation on the ground. That’s what happened with the Castleberry Fire. Having a clear picture of where it was burning most intensely enabled firefighters to focus on where they could make a difference — on the northeastern edge. Then, two days after identifying Castleberry Fire hot spots, the sensor spotted a fire about 4 miles (2.5 kilometers) southwest of Perdido, Alabama. As forestry officials worked to prevent flames from reaching six nearby buildings, they noticed that the fire’s main hot spot was inside the perimeter and contained. With that intelligence, they decided to shift some resources to fires 25 miles (40 kilometers) away near Mount Vernon, Alabama. To combat one of the Mount Vernon fires, crews used AVIRIS-3 maps to determine where to establish fire breaks beyond the northwestern end of the fire. They ultimately cut the blaze off within about 100 feet (30 meters) of four buildings. “Fire moves a lot faster than a bulldozer, so we have to try to get around it before it overtakes us. These maps show us the hot spots,” Barrett said. “When I get out of the truck, I can say, ‘OK, here’s the perimeter.’ That puts me light-years ahead.” AVIRIS and the Firesense Airborne Campaign are part of NASA’s work to leverage its expertise to combat wildfires using solutions including airborne technologies. The agency also recently demonstrated a prototype from its Advanced Capabilities for Emergency Response Operations project that will provide reliable airspace management for drones and other aircraft operating in the air above wildfires.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In our modern wireless world, almost all radio frequency (RF) spectrum bands are shared among multiple users. In some domains, similar users technically coordinate to avoid interference. The spectrum management team, part of NASA’s SCaN (Space Communications and Navigation) Program, represents the collaborative efforts across U.S. agencies and the international community to protect and enable NASA’s current and future spectrum-dependent science, exploration, and innovation. Coordination with Other Spectrum Stakeholders NASA works to promote the collaborative use of the RF spectrum around Earth, and beyond. For example, NASA coordinates closely with other U.S. government agencies, international civil space agencies, and the private sector to ensure missions that overlap in time, location, and frequency do not cause or receive interference that could jeopardize their success. The spectrum management team protects NASA’s various uses of the spectrum by collaborating with U.S. and international spectrum users on technical matters that inform regulatory discussions. As a founding member of the Space Frequency Coordination Group, NASA works with members of governmental space- and science-focused agencies from more than 35 countries. The Space Frequency Coordination Group annual meetings provide a forum for multilateral discussion and consideration of international spectrum regulatory issues related to Earth, lunar, and deep space research and exploration. The Space Frequency Coordination Group also provides a forum for the exchange of technical information to facilitate coordination for specific missions and enable efficient use of limited spectrum resources in space. Domestic and International Spectrum Regulators Creating and maintaining the global spectrum regulations that govern spectrum sharing requires collaboration and negotiation among all its diverse users. The International Telecommunication Union manages the global spectrum regulatory framework to optimize the increasing, diverse uses of the RF spectrum and reduce the likelihood of RF systems experiencing interference. U.S. regulators at the National Telecommunications and Information Administration and the Federal Communications Commission are responsible for developing and administering domestic spectrum regulations. Organizations across the world cooperatively plan and regulate spectrum use. The spectrum management team participates on behalf of NASA at both national and international levels to ensure that the U.S. domestic and international spectrum regulatory framework supports and enables NASA’s current and future missions. NASA collaborates with domestic and international spectrum stakeholders to provide technical expertise on space spectrum topics to ensure regulations continue to enable space exploration, science, and innovation.NASA Share Details Last Updated Apr 23, 2025 Related TermsGeneral Keep Exploring Discover Related Topics Missions Humans in Space Climate Change Solar System View the full article

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Spectrum is a shared resource. Since the discovery of radio waves and the invention of the telegraph, humanity has exponentially increased its use of the radio frequency (RF) spectrum. Consider how many wireless devices are around you right now. You’re probably reading this on a smartphone or laptop connected to the internet through Wi-Fi or 5G. You might be listening to music on Bluetooth headphones. If you are in a car or bus, the driver may be using signals from GPS satellites. To meet this increasing need, RF engineers and regulators continue to develop ways to enable users to share the same frequencies at the same time in the same place — think of modern cell phone technology. Avoiding or lessening interference between users requires regulators and users alike to maintain and enforce the ‘rules of the road’ that describe who can use which frequencies where, when, and how. NASA, like all other users, must comply with these regulations and collaborate with other users to ensure our use of the RF spectrum can continue and evolve. Just as architects design taller buildings to accommodate more residences on the same plot of land, radio frequency engineers design methods to allow more users on the same frequency, at the same place and time.NASA Supporting and Protecting NASA’s Spectrum Users NASA’s spectrum professionals work with users early in the project planning phase to understand the type, location, and duration of their data, and in turn determine what kind of antennas, transmitters, and receivers will be required. With that information, a spectrum manager helps to define the spectrum requirements, such as bandwidths, modulation, and other technical characteristics of the radio signals to be used. Understanding a project’s objectives helps define the appropriate service allocation and potential frequency ranges. Once these spectrum requirements are determined, NASA’s spectrum professionals work with other relevant spectrum users within and beyond NASA to coordinate the use of the spectrum. In the unfortunate event of harmful RF interference, working to identify, resolve, and report the interference is another critical function of NASA’s spectrum professionals. For example as Jeff Hayes — NASA’s current SCaN (Space Communications and Navigation) Program liaison to the Science Mission Directorate and the former program executive for operating missions in the Heliophysics and Astrophysics Divisions — recounts, “The NICER (Neutron Star Interior Composition Explorer) observatory did actually experience bouts of RF interference over certain parts of the world. As NICER uses GPS to understand where it is pointing to in the sky, interference can make the location information of the source imprecise, and that impacts the quality of the data collected. That data could potentially be attributed to the wrong star.” When NASA identifies interference to a mission like NICER or to a device at an agency center or facility, NASA center and facility spectrum managers work to identify, resolve, and report the interference. Identifying and reporting sources of interference helps to raise awareness of the impacts and causes of interference. When the sources of interference are international, which is especially common for space systems like NICER, SCaN’s spectrum management team works with U.S. regulators to report the incident to international regulators. These interference reports can be used to advocate for regulatory protections that help ensure the integrity of valuable science data and the safety of human spaceflight activities. Advocating for NASA’s Current and Future Spectrum Use NASA’s spectrum analysts and engineers perform analyses and simulations to support spectrum planning and management activities. For example, passive remote sensing instruments like the radiometer on the Soil Moisture Active Passive mission detect natural energy (radiation) emitted or reflected by an object or scene being observed. This energy is much fainter than human-generated radio signals and require highly sensitive radiometers that are susceptible to interference from more powerful signals. The spectrum management team works to ensure regulatory protections are in place and followed to ensure the integrity of NASA’s scientific missions. Sometimes NASA’s future missions envision new ways and places to use radio waves. For example, when NASA’s Artemis campaign began taking steps to return humans to the Moon, SCaN’s spectrum professionals began working with other stakeholders to develop a RF architecture that enables the use of radio waves for science data, communications, positioning, navigation, and timing while also limiting the risk of interference with systems on or orbiting Earth. NASA’s spectrum professionals further the agency’s spectrum management goals and objectives by analyzing potential changes in international or domestic regulations and proposing technical solutions that promote collaborative spectrum use with both foreign and domestic partners. NASA’s technical expertise is critical to ensuring domestic and international regulators are well informed as they develop new or revised regulations that effectively enable the exciting innovation and exploration central to NASA’s mission.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) As associate administrator for NASA’s Space Operations Mission Directorate Ken Bowersox puts it, “nothing happens without communications.” And effective communications require the use of radio waves. None of NASA’s exciting science and engineering endeavors would be possible without the use of radio waves to send data, communications, and commands between researchers or flight controllers and their flight platforms or instruments. Reflecting on his time as a pilot, commander, and mission specialist during the Space Shuttle Program, Bowersox says, “If you’re not there physically, you can’t be a part of the team. But if you’re getting the data, whether it’s video, telemetry data with states of switches, or individual parameters on temperatures or pressures, then you can act on it and provide information to the spacecraft team so they can do the right thing in their operation.” These vital data and communications functions, as well as the gathering of valuable scientific data through remote sensing applications, all use radio frequencies (RF) within the electromagnetic spectrum. NASA centers and facilities also use the RF spectrum to support their everyday operations, including the walkie-talkies used by security guards, air traffic control systems around airfields, and even office Wi-Fi routers and wireless keyboards. Nothing happens without communications. Ken Bowersox NASA Astronaut & Associate Administrator for NASA's Space Operations Mission Directorate All of NASA’s uses of the RF spectrum are shared, with different radio services supporting other kinds of uses. Service allocation is a fundamental concept in spectrum regulation and defines how the spectrum is shared between different types of applications. A service allocation defines ranges, or bands, of radio frequencies that can be used by a particular type of radio service. For example, a television broadcasting satellite operates in frequency bands allocated to the broadcasting satellite service, terrestrial cellular services operate in bands allocated for the mobile service, and the communications antennas on the International Space Station (ISS) operate in bands allocated to space operations service. However, an allocation is not a license to operate — it does not authorize a specific system or operator to use particular frequencies. Such authority is granted through domestic and international regulatory processes. Most frequency bands of the RF spectrum are shared, and each frequency band typically has two or more radio services allocated to it. Careful spectrum regulation, planning, and management aim to identify mutually compatible services to share frequency bands while limiting its negative impacts. NASA’s Most Notable Spectrum Uses Many of NASA’s most notable uses of spectrum rely on the following service allocations: Earth exploration-satellite service Space research service Space operations service Inter-satellite service Note that allocations in the Earth exploration-satellite service and the space research service are designated either for communications links in the Earth-to-space, space-to-Earth, or space-to-space directions or designated for active or passive sensing of Earth or celestial objects (respectively) to differentiate the types of uses within the service and afford the requisite protections.

After more than three decades of perusing the universe, Hubble remains a household name — the most well-recognized and scientifically productive telescope in history. The Hubble mission is a glowing success story of America’s technological prowess, unyielding scientific curiosity, and a reiteration of our nation’s pioneering spirit. “Hubble opened a new window to the universe when it launched 35 years ago. Its stunning imagery inspired people across the globe, and the data behind those images revealed surprises about everything from early galaxies to planets in our own solar system,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. “The fact that it is still operating today is a testament to the value of our flagship observatories, and provides critical lessons for the Habitable Worlds Observatory, which we plan to be serviceable in the spirit of Hubble.” Perched above Earth’s blurry atmosphere, Hubble’s crystal-clear views have been nothing less than transformative for the public’s perception of the cosmos. Through its evocative imagery, Hubble has made astronomy very relevant, engaging, and accessible for people of all ages. Hubble snapshots can portray the universe as awesome, mysterious, and beautiful — and at the same time chaotic, overwhelming, and foreboding.

Image: NASA, ESA, STScI; Image Processing: Joseph DePasquale (STScI), Alyssa Pagan (STScI) The 24,000-pound observatory was tucked away inside the space shuttle Discovery’s cargo bay and lofted into low Earth orbit on April 24, 1990. As the shuttle Discovery thundered skyward, the NASA commentator described Hubble as a “new window on the universe.” The telescope turned out to be exactly as promised, and more. More scientific papers than ever are based on Hubble data, thanks to the dedication, perseverance, and skills of engineers, scientists, and mission operators. Astronauts chased and rendezvoused with Hubble on five servicing missions in which they upgraded Hubble’s cameras, computers, and other support systems. The servicing missions took place from 1993 to 2009. The telescope’s mission got off to a shaky start in 1990 when an unexpected flaw was found in the observatory’s nearly eight-foot diameter primary mirror. Astronauts gallantly came to the rescue on the first shuttle servicing mission in December 1993 to improve Hubble’s sharpness with corrective optics. To date, Hubble has made nearly 1.7 million observations, looking at approximately 55,000 astronomical targets. Hubble discoveries have resulted in over 22,000 papers and over 1.3 million citations as of February 2025. All the data collected by Hubble is archived and currently adds up to over 400 terabytes, representing the biggest dataset for a NASA astrophysics mission besides the James Webb Space Telescope. Hubble’s long operational life has allowed astronomers to return to the same cosmic scenes multiple times to observe changes that happened during more than three decades: seasonal variability on the planets in our solar system, black hole jets travelling at nearly the speed of light, stellar convulsions, asteroid collisions, expanding supernova bubbles, and much more.

Credit: NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris; Narrator: Dr. Jennifer Wiseman Before 1990, powerful optical telescopes on Earth could see only halfway across the cosmos. Estimates for the age of the universe disagreed by a big margin. Supermassive black holes were only suspected to be the powerhouses behind a rare zoo of energetic phenomena. Not a single planet had been seen around another star. Among its long list of breakthroughs: Hubble’s deep field images unveiled myriad galaxies dating back to the early universe. The telescope also allowed scientists to precisely measure the universe’s expansion, find that supermassive black holes are common among galaxies, and make the first measurement of the atmospheres of exoplanets. Hubble also contributed to the discovery of dark energy, the mysterious phenomenon accelerating the expansion of universe, leading to the 2011 Nobel Prize in Physics. The relentless pace of Hubble’s trailblazing discoveries kick-started a new generation of space telescopes for the 21st century. Hubble provided the first observational evidence that there were myriad distant galaxies for Webb to pursue in infrared wavelengths that reach even farther beyond Hubble’s gaze. Now, Hubble and Webb are often being used in complement to study everything from exoplanets to galaxy evolution. Hubble’s planned successor, the Habitable Worlds Observatory, will have a significantly larger mirror than Hubble’s to study the universe in visible and ultraviolet light. It will be significantly sharper than Hubble and up to 100 times more sensitive to starlight. The Habitable Worlds Observatory will advance science across all of astrophysics, as Hubble has done for over three decades. A major goal of the future mission is to identify terrestrial planets around neighboring stars that might be habitable. The Hubble Space Telescope continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

The activation marks a milestone in preparation for future Green Run testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. For Green Run, teams will activate and test all systems to ensure the stage is ready to fly. Green Run will culminate with a hot fire of the stage’s four RL10 engines, just as during an actual mission. The interstage simulator component will function like the SLS interstage section that protects the upper stage during Artemis launches. The interstage simulator will do the same during Green Run testing of the stage at NASA Stennis. The interstage simulator gas system will provide helium, nitrogen, and hydrogen to the four RL10 engines for all wet dress and hot fire exercises and tests. During the activation process, NASA Stennis crews simulated the engines and flowed gases to mirror various conditions and collect data on pressures and temperatures. NASA Stennis teams conducted 80 different flow cases, calculating such items as flow rates, system pressure drop, and fill/vent times. The calculated parameters then were compared to models and analytics to certify the gas system meets performance requirements.

Credits: NASA/David Lam NASA has named nine finalists out of the 45 semifinalist student essays in the Power to Explore Challenge, a national writing competition for K-12 students featuring the enabling power of radioisotopes. Contestants were challenged to explore how NASA has powered some of its most famous science missions, and to dream up how their personal “superpowers” would energize their success on their own radioisotope-powered science mission. I am always so impressed by quality of the essays and the creativity of the ideas that the students submit to NASA’s Power to Explore Challenge. Carl Sandifer II Program Manager, NASA Radioisotope Power Systems Program The competition asked students to learn about NASA’s radioisotope power systems (RPS), likened to a “nuclear battery” that the agency uses to explore some of the most extreme destinations in our solar system and beyond. Long before the early days of Apollo, our Moon has inspired explorers of all ages to push beyond known limits to realize impossible dreams. These systems have enabled NASA to discover “moonquakes” on Earth’s Moon and study some of the most extreme moons of the solar system, which have active volcanoes, methane lakes, and ice glaciers. As of March 25, NASA has discovered over 891 moons, each with secrets ready to be unlocked. Students were challenged to pick any moon in our solar system’s exploration could be enabled by this space power systems. In 275 words or less, they dreamed up a unique exploration mission of this moon and described their own power to achieve their mission goals. The Power to Explore Challenge offered students the opportunity to learn more about these reliable power systems, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received 2,051 submitted entries from all 50 states, U.S. territories, and the Department of Defense Education Activity overseas. “I am always so impressed by quality of the essays and the creativity of the ideas that the students submit to NASA’s Power to Explore Challenge.” said Carl Sandifer, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland. “I’m looking forward to welcoming the winners to NASA’s Glenn this summer.” Entries were split into three categories: grades K-4, 5-8, and 9-12. Every student who submitted an entry received a digital certificate and an invitation to the Power Up virtual event held on March 21 that announced the semifinalists. Students learned about what powers the NASA workforce to dream big and work together to explore. Three national finalists in each grade category (nine finalists total) have been selected. In addition to receiving a NASA RPS prize pack, these participants will be invited to an exclusive virtual meeting with a NASA engineer or scientist to talk about their missions and have their space exploration questions answered.

5 Min Read Planetary Alignment Provides NASA Rare Opportunity to Study Uranus Artist's illustration showing a distant star going out of sight as it is eclipsed by Uranus – an event known as a planetary stellar occultation. Credits: NASA/Advanced Concepts Laboratory When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what happened with Uranus on April 7. Observing the alignment allows NASA scientists to measure the temperatures and composition of Uranus’ stratosphere – the middle layer of a planet’s atmosphere – and determine how it has changed over the last 30 years since Uranus’ last significant occultation. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video This rendering demonstrates what is happening during a stellar occultation and illustrates an example of the light curve data graph recorded by scientists that enables them to gather atmospheric measurements, like temperature and pressure, from Uranus as the amount of starlight changes when the planet eclipses the star.NASA/Advanced Concepts Laboratory “Uranus passed in front of a star that is about 400 light years from Earth,” said William Saunders, planetary scientist at NASA’s Langley Research Center in Hampton, Virginia, and science principal investigator and analysis lead, for what NASA’s team calls the Uranus Stellar Occultation Campaign 2025. “As Uranus began to occult the star, the planet’s atmosphere refracted the starlight, causing the star to appear to gradually dim before being blocked completely. The reverse happened at the end of the occultation, making what we call a light curve. By observing the occultation from many large telescopes, we are able to measure the light curve and determine Uranus’ atmospheric properties at many altitude layers.” We are able to measure the light curve and determine Uranus' atmospheric properties at many altitude layers. William Saunders Planetary Scientist at NASA's Langley Research Center This data mainly consists of temperature, density, and pressure of the stratosphere. Analyzing the data will help researchers understand how the middle atmosphere of Uranus works and could help enable future Uranus exploration efforts. To observe the rare event, which lasted about an hour and was only visible from Western North America, planetary scientists at NASA Langley led an international team of over 30 astronomers using 18 professional observatories. Kunio Sayanagi, NASA’s principal investigator for the Uranus Stellar Occultation Campaign 2025, meeting virtually with partners and observing data from the Flight Mission Support Center at NASA’s Langley Research Center in Hampton, Virginia during Uranus’ stellar occultation event on April 7, 2025.NASA/Dave MacDonnell “This was the first time we have collaborated on this scale for an occultation,” said Saunders. “I am extremely grateful to each member of the team and each observatory for taking part in this extraordinary event. NASA will use the observations of Uranus to determine how energy moves around the atmosphere and what causes the upper layers to be inexplicably hot. Others will use the data to measure Uranus’ rings, its atmospheric turbulence, and its precise orbit around the Sun.” Knowing the location and orbit of Uranus is not as simple as it sounds. In 1986, NASA’s Voyager 2 spacecraft became the first and only spacecraft to fly past the planet – 10 years before the last bright stellar occultation occured in 1996. And, Uranus’ exact position in space is only accurate to within about 100 miles, which makes analyzing this new atmospheric data crucial to future NASA exploration of the ice giant. These investigations were possible because the large number of partners provided many unique views of the stellar occultation from many different instruments. NASA planetary scientist William Saunders and Texas A&M University research assistant Erika Cook in the control room of the McDonald Observatory’s Otto Struve Telescope in Jeff Davis County, Texas, during the Uranus stellar occultation on April 7, 2025.Joshua Santana Emma Dahl, a postdoctoral scholar at Caltech in Pasadena, California, assisted in gathering observations from NASA’s Infrared Telescope Facility (IRTF) on the summit of Mauna Kea in Hawaii – an observatory first built to support NASA’s Voyager missions. “As scientists, we do our best work when we collaborate. This was a team effort between NASA scientists, academic researchers, and amateur astronomers,” said Dahl. “The atmospheres of the gas and ice giant planets [Jupiter, Saturn, Uranus, and Neptune] are exceptional atmospheric laboratories because they don’t have solid surfaces. This allows us to study cloud formation, storms, and wind patterns without the extra variables and effects a surface produces, which can complicate simulations very quickly.” On November 12, 2024, NASA Langley researchers and collaborators were able to do a test run to prepare for the April occultation. Langley coordinated two telescopes in Japan and one in Thailand to observe a dimmer Uranus stellar occultation only visible from Asia. As a result, these observers learned how to calibrate their instruments to observe stellar occultations, and NASA was able to test its theory that multiple observatories working together could capture Uranus’ big event in April. Researchers from the Paris Observatory and Space Science Institute, in contact with NASA, also coordinated observations of the November 2024 occultation from two telescopes in India. These observations of Uranus and its rings allowed the researchers, who were also members of the April 7 occultation team, to improve the predictions about the timing on April 7 down to the second and also improved modeling to update Uranus’ expected location during the occultation by 125 miles. This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope exquisitely captures Uranus’s seasonal north polar cap and dim inner and outer rings. This Webb image also shows 9 of the planet’s 27 moons – clockwise starting at 2 o’clock, they are: Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita.NASA, ESA, CSA, STScI Uranus is almost 2 billion miles away from Earth and has an atmosphere composed of primarily hydrogen and helium. It does not have a solid surface, but rather a soft surface made of water, ammonia, and methane. It’s called an ice giant because its interior contains an abundance of these swirling fluids that have relatively low freezing points. And, while Saturn is the most well-known planet for having rings, Uranus has 13 known rings composed of ice and dust. Over the next six years, Uranus will occult several dimmer stars. NASA hopes to gather airborne and possibly space-based measurements of the next bright Uranus occultation in 2031, which will be of an even brighter star than the one observed in April.

2 min read First Results from the Eclipse Soundscapes Project: Webinar on May 7 How do the sudden darkness and temperature changes of a solar eclipse impact life on Earth? The Eclipse Soundscapes project invited you to document changes in the environment during the week of the April 8, 2024 total solar eclipse, using your own senses or an audiomoth sound recorder. Thanks to your participation, the Eclipse Soundscapes team collected 25 terabytes of audio data during the 2023 and 2024 solar eclipses. “It was really empowering for me to participate in a scientific research study with my son beside me so he could see how scientific data can be (collected),” said one Eclipse Soundscapes volunteer. More than 500 volunteers collected data using AudioMoth recorders during the April 8, 2024 eclipse for the Eclipse Soundscapes project. Credit: Eclipse Soundscapes Since the eclipse, the Eclipse Soundscapes team has been turning the submitted data into a new, carefully validated data set. They have been assessing recording quality, verifying timestamps, and logging other kinds of information that support the submitted data. With the newly validated data, they are now using machine learning to study wildlife behavior and compare regional differences. They do some of this work using spectrographic analysis—spreading out the sound into different frequency ranges like a prism spreads light into a rainbow. The team is also working to make the validated data freely available to the public on the Zenodo website—a free, open-source research data repository developed by CERN (the European Organization for Nuclear Research) that allows researchers to share and preserve their work, regardless of discipline or format. The team’s first inspection of the data suggests that some species may mimic dusk-like behavior during totality. Want to hear more early results?

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A researcher inspects the interior of a male American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem.NASA They’re known as “living fossils”. For over 450 million years, horseshoe crabs have been an ecologically vital part of our planet. They’re one of the few surviving species on Earth dating back to the dinosaurs. At NASA’s Kennedy Space Center in Florida, the American horseshoe crab (Limulus polyphemus) is one of more than 1,500 types of animals and plants you can find living on its over 144,000 acres, the majority of which is managed by the U.S. Fish and Wildlife Service and National Park Service. Sharing a boundary with the Merritt Island National Wildlife Refuge and Canaveral National Seashore, NASA Kennedy is one of the most biologically diverse places in the United States. The center’s land, water, and air species live alongside the symbols of America’s space program: the vital facilities and infrastructure that support the many launches at NASA Kennedy and Cape Canaveral Space Force Station as well as the rockets enabling humanity’s exploration of the cosmos. Researchers measure the shell of a male and female American horseshoe crab at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. Preserving NASA Kennedy’s wildlife while also fulfilling the agency’s mission requires a balanced approach. The American horseshoe crab exemplifies that balance. Horseshoe crabs are keystone species in coastal and estuary systems like the ones surrounding Earth’s premier spaceport. By themselves, these resilient arthropods are a strong indicator of how an ecosystem is doing to support the migratory birds, sea turtles, alligators and other wildlife who rely on it for their survival. “The presence and abundance of horseshoe crabs influence the structure and functioning of the entire ecosystem,” said James T. Brooks, an environmental protection specialist at NASA Kennedy. “Their eggs provide a vital food source for many shorebirds in coastal habitats, and their feeding activities help shape the composition of plants and animals that live at the bottom of the ocean or in rivers and lakes. Changes in horseshoe crab populations can signal broader ecological issues, such as pollution or habitat loss.” As featured recently on NASA+, biologists survey NASA Kennedy’s beaches regularly for horseshoe crabs, counting each one they spot and tagging them with devices that lets researchers study their migration patterns and survival rates. The devices also track the crabs’ spawning activity, habitat health, and population trends, especially during peak breeding seasons in spring and summer. All this data helps in assessing the overall health of NASA Kennedy’s ecosystem, but horseshoe crabs also play a vital role in humanity’s health. Their blue, copper-based blood contains a substance called Limulus Amebocyte Lysate, critical for detecting bacterial contamination in medical equipment, pharmaceuticals, and vaccines. Their unique value in ensuring biomedical safety underscores why NASA Kennedy emphasizes ecological monitoring in addition to its roles in the global space economy, national defense, and space exploration. A male and female American horseshoe crab meet during mating season at NASA’s Kennedy Space Center in Florida. Known scientifically as Limulus polyphemus, the American horseshoe crab is vital to researchers’ understanding of the overall health of NASA Kennedy’s ecosystem. NASA At NASA Kennedy, horseshoe crabs are protected and monitored through habitat restoration projects like rebuilding shorelines eroded by storms and minimizing human impact on nesting sites. These initiatives ensure that the spaceport’s operations coexist harmoniously with nature and deepen our understanding of Earth’s interconnected ecosystems. On this Earth Day, NASA Kennedy celebrates the important role these ancient mariners play as we launch humanity’s future. About the AuthorMessod C.

4 min read Entrepreneurs Challenge Winner PRISM is Using AI to Enable Insights from Geospatial Data PRISM’s platform uses AI segmentation to identify and highlight residential structures in a neighborhood. NASA sponsored Entrepreneurs Challenge events in 2020, 2021, and 2023 to invite small business start-ups to showcase innovative ideas and technologies with the potential to advance the agency’s science goals. To potentially 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 refined their products and/or received funding from NASA and external sources (e.g., other government agencies or the venture capital community) to further develop their technologies. One 2023 Entrepreneurs Challenge winner, PRISM Intelligence (formerly known as Pegasus Intelligence and Space), is using artificial intelligence (AI) and other advances in computer vision to create a new platform that could provide geospatial insights to a broad community. Every day, vast amounts of remote sensing data are collected through satellites, drones, and aerial imagery, but for most businesses and individuals, accessing and extracting meaningful insights from this data is nearly impossible. The company’s product—Personal Real-time Insight from Spatial Maps, a.k.a. PRISM—is transforming geospatial data into an easy-to-navigate, queryable world. By leveraging 3D computer vision, geospatial analytics, and AI-driven insights, PRISM creates photorealistic, up-to-date digital environments that anyone can interact with. Users can simply log in and ask natural-language questions to instantly retrieve insights—no advanced Geographic Information System (GIS) expertise is required. For example, a pool cleaner looking for business could use PRISM to search for all residential pools in a five-mile radius. A gardener could identify overgrown trees in a community. City officials could search for potholes in their jurisdiction to prioritize repairs, enhance public safety, and mitigate liability risks. This broad level of accessibility brings geospatial intelligence out of the hands of a few and into everyday decision making. The core of PRISM’s platform uses radiance fields to convert raw 2D imagery into high-fidelity, dynamic 3D visualizations. These models are then enhanced with AI-powered segmentation, which autonomously identifies and labels objects in the environment—such as roads, vehicles, buildings, and natural features—allowing for seamless search and analysis. The integration of machine learning enables PRISM to refine its reconstructions continuously, improving precision with each dataset. This advanced processing ensures that the platform remains scalable, efficient, and adaptable to various data sources, making it possible to produce large-scale, real-time digital twins of the physical world. The PRISM platform’s interface showcasing a 3D digital twin of California State Polytechnic University, Pomona, with AI-powered search and insights. “It’s great being able to push the state of the art in this relatively new domain of radiance fields, evolving it from research to applications that can impact common tasks. From large sets of images, PRISM creates detailed 3D captures that embed more information than the source pictures.” — Maximum Wilder-Smith, Chief Technology Officer, PRISM Intelligence Currently the PRISM platform uses proprietary data gathered from aerial imagery over selected areas. PRISM then generates high-resolution digital twins of cities in select regions. The team is aiming to eventually expand the platform to use NASA Earth science data and commercial data, which will enable high-resolution data capture over larger areas, significantly increasing efficiency, coverage, and update frequency. PRISM aims to use the detailed multiband imagery that NASA provides and the high-frequency data that commercial companies provide to make geospatial intelligence more accessible by providing fast, reliable, and up-to-date insights that can be used across multiple industries. What sets PRISM apart is its focus on usability. While traditional GIS platforms require specialized training to use, PRISM eliminates these barriers by allowing users to interact with geospatial data through a frictionless, conversational interface. The impact of this technology could extend across multiple industries. Professionals in the insurance and appraisal industries have informed the company how the ability to generate precise, 3D assessments of properties could streamline risk evaluations, reduce costs, and improve accuracy—replacing outdated or manual site visits. Similarly, local governments have indicated they could potentially use PRISM to better manage infrastructure, track zoning compliance, and allocate resources based on real-time, high-resolution urban insights. Additionally, scientists could use the consistent updates and layers of three-dimensional data that PRISM can provide to better understand changes to ecosystems and vegetation. As PRISM moves forward, the team’s focus remains on scaling its capabilities and expanding its applications. Currently, the team is working to enhance the technical performance of the platform while also adding data sources to enable coverage of more regions. Future iterations will further improve automation of data processing, increasing the speed and efficiency of real-time 3D reconstructions. The team’s goal is to expand access to geospatial insights, ensuring that anyone—from city planners to business owners—can make informed decisions using the best possible data.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Researchers use a flat aerogel array antenna to communicate with a geostationary satellite above the Earth during tests at NASA’s Glenn Research Center in Cleveland.Credit: NASA/Jordan Cochran NASA engineers are using one of the world’s lightest solid materials to construct an antenna that could be embedded into the skin of an aircraft, creating a more aerodynamic and reliable communication solution for drones and other future air transportation options. Developed by NASA, this ultra-lightweight aerogel antenna is designed to enable satellite communications where power and space are limited. The aerogel is made up of flexible, high-performance plastics known as polymers. The design features high air content (95%) and offers a combination of light weight and strength. Researchers can adjust its properties to achieve either the flexibility of plastic wrap or the rigidity of plexiglass. “By removing the liquid portion of a gel, you’re left with this incredibly porous structure,” said Stephanie Vivod, a chemical engineer at NASA’s Glenn Research Center in Cleveland. “If you’ve ever made Jell-O, you’ve performed chemistry that’s similar to the first step of making an aerogel.” NASA sandwiched a layer of aerogel between a small circuit board and an array of thin, circular copper cells, then topped the design off with a type of film known for its electrical insulation properties. This innovation is known at NASA and in the aviation community as an active phased array aerogel antenna. A sample of aerogel is folded to demonstrate its flexibility during testing at NASA’s Glenn Research Center in Cleveland.Credit: NASA In addition to decreasing drag by conforming to the shape of aircraft, aerogel antennas save weight and space and come with the ability to adjust their individual array elements to reduce signal interference. They are also less visually intrusive compared to other types of antennas, such as spikes and blades. The finished product looks like a honeycomb but lays flat on an aircraft’s surface. In the summer of 2024, researchers tested a rigid version of the antenna on a Britten-Norman Defender aircraft during an in-flight demonstration with the U.S. Navy at Naval Air Station Patuxent River in Maryland. A Britten-Norman Defender aircraft outfitted with an advanced phased array antenna prototype for a flight test in summer 2024. The aircraft was used to verify data transmission quality and communications link resiliency with a low Earth orbit satellite.Credit: U.S. Navy Then, last October, researchers at NASA Glenn and the satellite communications firm Eutelsat America Corp., of Houston, began ground testing a version of the antenna mounted to a platform. The team successfully connected with a Eutelsat satellite in geostationary orbit, which bounced a signal back down to a satellite dish on a building at Glenn. Other demonstrations of the system at Glenn connected with a constellation of communications satellites operated in low Earth orbit by the data relay company Kepler. NASA researchers will design, build, and test a flexible version of the antenna later this year. “This is significant because we are able to use the same antenna to connect with two very different satellite systems,” said Glenn researcher Bryan Schoenholz. Low Earth orbit satellites are relatively close – at 1,200 miles from the surface – and move quickly around the planet. Geostationary satellites are much farther – more than 22,000 miles from the surface – but orbit at speeds matching the Earth’s rotation, so they appear to remain in a fixed position above the equator. NASA Glenn Research Center’s Sarah Dever and Mick Koch, electrical engineers, command an active phased array antenna to point toward a geostationary satellite. They used a flat version of an aerogel antenna during tests in October 2024.Credit: NASA/Jordan Cochran The satellite testing was crucial for analyzing the aerogel antenna concept’s potential real-world applications. When modern aircraft communicate with stations on the ground, those signals are often transmitted through satellite relays, which can come with delays and loss of communication. This NASA-developed technology will make sure these satellite links are not disrupted during flight as the aerogel antenna’s beam is a concentrated flow of radio waves that can be electronically steered with precision to maintain the connection. As new types of air transportation options are brought to the market and U.S airspace – from the small, piloted aircraft of today to the autonomous air taxis and delivery drones of tomorrow – these kinds of steady connections will become increasingly important. That’s why NASA’s Advanced Air Mobility mission and Transformative Aeronautics Concepts program are supporting research like the aerogel antennas that can boost industry efforts to safely expand the emerging marketplace for these transportation systems. “If an autonomous air taxi or drone flight loses its communications link, we have a very unsafe situation,” Schoenholz said. “We can’t afford a ‘dropped call’ up there because that connection is critical to the safety of the flight.” Schoenholz, Vivod, and others work on NASA’s Antenna Deployment and Optimization Technologies activity within the Transformational Tools and Technologies project. The activity aims to develop technologies that reduce the risk of radio frequency interference from air taxis, drones, commercial passenger jets, and other aircraft in increasingly crowded airspace.
