NASA Selects 2 Instruments for Artemis IV Lunar Surface Science
4 min read
NASA Selects 2 Instruments for Artemis IV Lunar Surface ScienceNASA has selected two science instruments designed for astronauts to deploy on the surface of the Moon during the Artemis IV mission to the lunar south polar region. The instruments will improve our knowledge of the lunar environment to support NASA’s further exploration of the Moon and beyond to Mars.
A visualization of the Moon’s South Pole region created with data from NASA’s Lunar Reconnaissance Orbiter, which has been surveying the Moon with seven instruments since 2009. NASA’s Scientific Visualization Studio/Ernie Wright“The Apollo Era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “By deploying these two science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon and onward to Mars.”
After his voyage to the Moon’s surface during Apollo 17, astronaut Gene Cernan acknowledged the challenge that lunar dust presents to long-term lunar exploration. Moon dust sticks to everything it touches and is very abrasive. The knowledge gained from the DUSTER (DUst and plaSma environmenT survEyoR) investigation will help mitigate hazards to human health and exploration. Consisting of a set of instruments mounted on a small autonomous rover, DUSTER will characterize dust and plasma around the landing site. These measurements will advance understanding of the Moon’s natural dust and plasma environment and how that environment responds to the human presence, including any disturbance during crew exploration activities and lander liftoff. The DUSTER instrument suite is led by Xu Wang of the University of Colorado Boulder. The contract is for $24.8 million over a period of three years.
A model of the DUSTER instrument suite consisting of the Electrostatic Dust Analyzer (EDA)—which will measure the charge, velocity, size, and flux of dust particles lofted from the lunar surface—and Relaxation SOunder and differentiaL VoltagE (RESOLVE)—which will characterize the average electron density above the lunar surface using plasma sounding. Both instruments will be housed on a Mobile Autonomous Prospecting Platform (MAPP) rover, which will be supplied by Lunar Outpost, a company based in Golden, Colorado, that develops and operates robotic systems for space exploration.LASP/CU Boulder/Lunar OutpostData from the SPSS (South Pole Seismic Station) will enable scientists to characterize the lunar interior structure to better understand the geologic processes that affect planetary bodies. The seismometer will help determine the current rate at which the Moon is struck by meteorite impacts, monitor the real-time seismic environment and how it can affect operations for astronauts, and determine properties of the Moon’s deep interior. The crew will additionally perform an active-source experiment using a “thumper” that creates seismic energy to survey the shallow structure around the landing site. The SPSS instrument is led by Mark Panning of NASA’s Jet Propulsion Laboratory in Southern California. The award is for $25 million over a period of three years.
An artist’s concept of SPSS (South Pole Seismic Station) to be deployed by astronauts on the lunar surface.NASA/JPL-Caltech“These two scientific investigations will be emplaced by human explorers on the Moon to achieve science goals that have been identified as strategically important by both NASA and the larger scientific community”, said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate at NASA Headquarters. “We are excited to integrate these instrument teams into the Artemis IV Science Team.”
The two payloads were selected for further development to fly on Artemis IV; however, final manifesting decisions about the mission will be determined at a later date.
Through Artemis, NASA will address high priority science questions, focusing on those that are best accomplished by on-site human explorers on and around the Moon and by using the unique attributes of the lunar environment, aided by robotic surface and orbiting systems. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

NASA-JAXA XRISM Finds Elemental Bounty in Supernova Remnant
4 min read
NASA-JAXA XRISM Finds Elemental Bounty in Supernova RemnantFor the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft.
The Resolve instrument aboard XRISM, pronounced “crism,” discovered these elements in a supernova remnant called Cassiopeia A or Cas A, for short. The expanding cloud of debris is located about 11,000 light-years away in the northern constellation Cassiopeia.
“This discovery helps illustrate how the deaths of stars and life on Earth are fundamentally linked,” said Toshiki Sato, an astrophysicist at Meiji University in Tokyo. “Stars appear to shimmer quietly in the night sky, but they actively forge materials that form planets and enable life as we know it. Now, thanks to XRISM, we have a better idea of when and how stars might make crucial, yet harder-to-find, elements.”
A paper about the result published Dec. 4 in Nature Astronomy. Sato led the study with Kai Matsunaga and Hiroyuki Uchida, both at Kyoto University in Japan. JAXA (Japan Aerospace Exploration Agency) leads XRISM in collaboration with NASA, along with contributions from ESA (European Space Agency). NASA and JAXA also codeveloped the Resolve instrument.
Observations of the Cassiopeia A supernova remnant by the Resolve instrument aboard the NASA-JAXA XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft revealed strong evidence for potassium (green squares) in the southeast and northern parts of the remnant. Grids superposed on a multiwavelength image of the remnant represent the fields of view of two Resolve measurements made in December 2023. Each square represents one pixel of Resolve’s detector. Weaker evidence of potassium (yellow squares) in the west suggests that the original star may have had underlying asymmetries before it exploded.NASA’s Goddard Space Flight Center; X-ray: NASA/CXC/SAO; Optical: NASA/ESA/STScI; IR: NASA/ESA/CSA/STScI/Milisavljevic et al., NASA/JPL/CalTech; Image Processing: NASA/CXC/SAO/J. Schmidt and K. Arcand Download high-resolution images from NASA’s Scientific Visualization StudioStars produce almost all the elements in the universe heavier than hydrogen and helium through nuclear reactions. Heat and pressure fuse lighter ones, like carbon, into progressively heavier ones, like neon, creating onion-like layers of materials in stellar interiors.
Nuclear reactions also take place during explosive events like supernovae, which occur when stars run out of fuel, collapse, and explode. Elemental abundances and locations in the wreckage can, respectively, tell scientists about the star and its explosion, even after hundreds or thousands of years.
Some elements — like oxygen, carbon, and neon — are more common than others and are easier to detect and trace back to a particular part of the star’s life.
Other elements — like chlorine and potassium — are more elusive. Since scientists have less data about them, it’s more difficult to model where in the star they formed. These rarer elements still play important roles in life on Earth. Potassium, for example, helps the cells and muscles in our bodies function, so astronomers are interested in tracing its cosmic origins.
The roughly circular Cas A supernova remnant spans about 10 light-years, is over 340 years old, and has a superdense neutron star at its center — the remains of the original star’s core. Scientists using NASA’s Chandra X-ray Observatory had previously identified signatures of iron, silicon, sulfur, and other elements within Cas A.
In the hunt for other elements, the team used the Resolve instrument aboard XRISM to look at the remnant twice in December 2023. The researchers were able to pick out the signatures for chlorine and potassium, determining that the remnant contains ratios much higher than expected. Resolve also detected a possible indication of phosphorous, which was previously discovered in Cas A by infrared missions.

“Resolve’s high resolution and sensitivity make these kinds of measurements possible,” said Brian Williams, the XRISM project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Combining XRISM’s capabilities with those of other missions allows scientists to detect and measure these rare elements that are so critical to the formation of life in the universe.”
The astronomers think stellar activity could have disrupted the layers of nuclear fusion inside the star before it exploded. That kind of upheaval might have led to persistent, large-scale churning of material inside the star that created conditions where chlorine and potassium formed in abundance.
The scientists also mapped the Resolve observations onto an image of Cas A captured by Chandra and showed that the elements were concentrated in the southeast and northern parts of the remnant.
This lopsided distribution may mean that the star itself had underlying asymmetries before it exploded, which Chandra data indicated earlier this year in a study Sato led.
“Being able to make measurements with good statistical precision of these rarer elements really helps us understand the nuclear fusion that goes on in stars before and during supernovae,” said co-author Paul Plucinsky, an astrophysicist at the Center for Astrophysics | Harvard & Smithsonian in Cambridge, Massachusetts. “We suspected a key part might be asymmetry, and now we have more evidence that’s the case. But there’s still a lot we just don’t understand about how stars explode and distribute all these elements across the cosmos.”

NASA Completes Nancy Grace Roman Space Telescope Construction
NASA’s next big eye on the cosmos is now fully assembled. On Nov. 25, technicians joined the inner and outer portions of the Nancy Grace Roman Space Telescope in the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.
NASA’s Nancy Grace Roman Space Telescope is now fully assembled following the integration of its two major segments on Nov. 25 at the agency’s Goddard Space Flight Center in Greenbelt, Md. The mission is slated to launch by May 2027, but the team is on track for launch as early as fall 2026.Credit: NASA/Jolearra Tshiteya“Completing the Roman observatory brings us to a defining moment for the agency,” said NASA Associate Administrator Amit Kshatriya. “Transformative science depends on disciplined engineering, and this team has delivered—piece by piece, test by test—an observatory that will expand our understanding of the universe. As Roman moves into its final stage of testing following integration, we are focused on executing with precision and preparing for a successful launch on behalf of the global scientific community.”
After final testing, Roman will move to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Roman is slated to launch by May 2027, but the team is on track for launch as early as fall 2026. A SpaceX Falcon Heavy rocket will send the observatory to its final destination a million miles from Earth.
“With Roman’s construction complete, we are poised at the brink of unfathomable scientific discovery,” said Julie McEnery, Roman’s senior project scientist at NASA Goddard. “In the mission’s first five years, it’s expected to unveil more than 100,000 distant worlds, hundreds of millions of stars, and billions of galaxies. We stand to learn a tremendous amount of new information about the universe very rapidly after Roman launches.”
NASA’s Nancy Grace Roman Space Telescope will survey vast swaths of sky during its five-year primary mission. During that time, scientists expect it to see an incredible number of new objects, including stars, galaxies, black holes and planets outside our solar system, known as exoplanets. This infographic previews some of the discoveries scientists anticipate from Roman’s data deluge. Credit: NASA’s Goddard Space Flight CenterObserving from space will make Roman very sensitive to infrared light — light with a longer wavelength than our eyes can see — from far across the cosmos. Pairing its crisp infrared vision with a sweeping view of space will allow astronomers to explore myriad cosmic topics, from dark matter and dark energy to distant worlds and solitary black holes, and conduct research that would take hundreds of years using other telescopes.
“Within our lifetimes, a great mystery has arisen about the cosmos: why the expansion of the universe seems to be accelerating. There is something fundamental about space and time we don’t yet understand, and Roman was built to discover what it is,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “With Roman now standing as a complete observatory, which keeps the mission on track for a potentially early launch, we are a major step closer to understanding the universe as never before. I couldn’t be prouder of the teams that have gotten us to this point.”
Double vision
Roman is equipped with two instruments: the Wide Field Instrument and the Coronagraph Instrument technology demonstration.
The coronagraph will demonstrate new technologies for directly imaging planets around other stars. It will block the glare from distant stars and make it easier for scientists to see the faint light from planets in orbit around them. The Coronagraph aims to photograph worlds and dusty disks around nearby stars in visible light to help us see giant worlds that are older, colder, and in closer orbits than the hot, young super-Jupiters direct imaging has mainly revealed so far.
“The question of ‘Are we alone?’ is a big one, and it’s an equally big task to build tools that can help us answer it,” said Feng Zhao, the Roman Coronagraph Instrument manager at NASA’s Jet Propulsion Laboratory in Southern California. “The Roman Coronagraph is going to bring us one step closer to that goal. It’s incredible that we have the opportunity to test this hardware in space on such a powerful observatory as Roman.”
The coronagraph team will conduct a series of pre-planned observations for three months spread across the mission’s first year-and-a-half of operations, after which the mission may conduct additional observations based on scientific community input.
The Wide Field Instrument is a 288-megapixel camera that will unveil the cosmos all the way from our solar system to near the edge of the observable universe. Using this instrument, each Roman image will capture a patch of the sky bigger than the apparent size of a full moon. The mission will gather data hundreds of times faster than NASA’s Hubble Space Telescope, adding up to 20,000 terabytes (20 petabytes) over the course of its five-year primary mission.
“The sheer volume of the data Roman will return is mind-boggling and key to a host of exciting investigations,” said Dominic Benford, Roman’s program scientist at NASA Headquarters.

Using the Wide Field Instrument, Roman will conduct three core surveys which will account for 75% of the primary mission. The High-Latitude Wide-Area Survey will combine the powers of imaging and spectroscopy to unveil more than a billion galaxies strewn across a wide swath of space and time. Astronomers will trace the evolution of the universe to probe dark matter — invisible matter detectable only by how its gravity affects things we can see — and trace the formation of galaxies and galaxy clusters over time.
The High-Latitude Time-Domain Survey will probe our dynamic universe by observing the same region of the cosmos repeatedly. Stitching these observations together to create movies will allow scientists to study how celestial objects and phenomena change over time periods of days to years. That will help astronomers study dark energy — the mysterious cosmic pressure thought to accelerate the universe’s expansion — and could even uncover entirely new phenomena that we don’t yet know to look for.
Roman’s Galactic Bulge Time-Domain Survey will look inward to provide one of the deepest views ever of the heart of our Milky Way galaxy. Astronomers will watch hundreds of millions of stars in search of microlensing signals — gravitational boosts of a background star’s light caused by the gravity of an intervening object. While astronomers have mainly discovered star-hugging worlds, Roman’s microlensing observations can find planets in the habitable zone of their star and farther out, including worlds like every planet in our solar system except Mercury. Microlensing will also reveal rogue planets—worlds that roam the galaxy untethered to a star — and isolated black holes. The same dataset will reveal 100,000 worlds that transit, or pass in front of, their host stars.
The remaining 25% of Roman’s five-year primary mission will be dedicated to other observations that will be determined with input from the broader scientific community. The first such program, called the Galactic Plane Survey, has already been selected.
Because Roman’s observations will enable such a wide range of science, the mission will have a General Investigator Program designed to support astronomers to reveal scientific discoveries using Roman data. As part of NASA’s commitment to Gold Standard Science, NASA will make all of Roman’s data publicly available with no exclusive use period. This ensures multiple scientists and teams can use data at the same time, which is important since every Roman observation will address a wealth of science cases.
NASA’s freshly assembled Nancy Grace Roman Space Telescope will revolutionize our understanding of the universe with its deep, crisp, sweeping infrared views of space. The mission will transform virtually every branch of astronomy and bring us closer to understanding the mysteries of dark energy, dark matter, and how common planets like Earth are throughout our galaxy. Roman is on track for launch by May 2027, with teams working toward a launch as early as fall 2026. Credit: NASA’s Goddard Space Flight CenterRoman’s namesake — Dr. Nancy Grace Roman, NASA’s first chief astronomer — made it her personal mission to make cosmic vistas readily accessible to all by paving the way for telescopes based in space.
“The mission will acquire enormous quantities of astronomical imagery that will permit scientists to make groundbreaking discoveries for decades to come, honoring Dr. Roman’s legacy in promoting scientific tools for the broader community,” said Jackie Townsend, Roman’s deputy project manager at NASA Goddard. “I like to think Dr. Roman would be extremely proud of her namesake telescope and thrilled to see what mysteries it will uncover in the coming years.”
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory in Southern California; Caltech/IPAC in Pasadena, California; the Space Telescope Science Institute in Baltimore; and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems Inc. in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

If not taken into consideration, these water droplets can accumulate on an aircraft as ice and pose a safety risk.
But NASA software tools such as Glenn Icing Computational Environment (GlennICE) are working to keep passengers and pilots safe.
NASA developed GlennICE, a new NASA software code, to transform the way we explore, understand, and prevent ice buildup on aircraft wings and engines, as well as control surfaces like rudders and elevators.
Owing to decades of world-class NASA research, engineers nationwide can now use GlennICE to design aircraft in such a way that ice buildup will either occur rarely or pose very little risk.
Named for NASA’s Glenn Research Center in Cleveland, GlennICE is part of NASA’s work to provide the aviation industry with computational tools, including design software, to improve aircraft safety and enable innovation. For icing research and modeling, NASA computer codes have become the industry standard over the past several decades. And GlennICE builds on this work, performing highly advanced digital modeling of water and ice particles in just about any atmospheric condition you can imagine.
With updated capabilities and a streamlined user experience, GlennICE will enable users to advance the state of the art – particularly researchers working on complex, unusual future aircraft designs.
“The legacy codes are well formulated to handle simulations of traditional tube-and-wing shaped aircraft,” said Christopher Porter, lead for GlennICE’s development. “But now, we have new vehicles with new designs that present icing research challenges. This requires a more advanced tool, and that’s where GlennICE comes in.”
So far, dozens of industry partners as well as other government agencies have started using GlennICE, which is available on NASA’s software catalog.

The new toolkit can be tailored to unique situations and is compatible with other software tools. In other words, it is more configurable, and much less time consuming for researchers to set up and use.
This streamlined process, along with its more-advanced ability to model icing, allows GlennICE to easily tackle 21st-century concepts such as supersonic planes, advanced air mobility drones and other aircraft, unconventionally shaped wings, open-rotor turbofan designs, or new configurations for conventional aircraft such as radar domes.
But how does this simulation process work?
“Imagine an aircraft flying through a cloud,” Porter said. “Some of those water and ice droplets hit the aircraft and some of them don’t. GlennICE simulates these droplets and exactly where they will end up, both on the aircraft and not.”
When these water droplets hit the aircraft, they attach, freeze, and start to gather even more droplets that do the same. The software simulates exactly where this will occur, and what shape the ice will take over time.
“We’re not just dealing with the airplane, but the physics of the air and water as well,” Porter said.
Because it’s designed for simulating droplets, researchers have expressed interest in using GlennICE to simulate other conditions involving sand and ash. These substances, when ingested by aircraft engines, can pose separate risks that aeronautical engineers work to prevent.

Credit: NASA/Thomas Ozoroski World-class researchIcing research is fundamental to aviation safety, and NASA fulfils a key role in ensuring pilots and passengers fly more safely and ice-free. The agency’s wind tunnels, for instance, have world-class icing research capabilities not commonly found in aeronautics research.
Paired with wind tunnel testing, GlennICE offers a holistic set of capabilities to researchers. While wind tunnels can verify and validate data with real-world models and conditions, tools like GlennICE can fill gaps in research not easily achieved with wind tunnels.
“Some environments we need to test in are impractical with wind tunnels because of the tunnel size required and complex physics involved,” Porter said. “But with GlennICE, we can do these tests digitally. For example, we can model all the icing conditions noted in new regulations.”
The GlennICE development falls under NASA’s Transformative Aeronautics Concept and Advanced Air Vehicles programs. Those programs supported GlennICE to further NASA’s work on computational tool development for aerospace design. More about the history of icing research at NASA is available on the agency’s website.

NASA Completes Nancy Grace Roman Space Telescope Construction
NASA’s next big eye on the cosmos is now fully assembled. On Nov. 25, technicians joined the inner and outer portions of the Nancy Grace Roman Space Telescope in the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.
NASA’s Nancy Grace Roman Space Telescope is now fully assembled following the integration of its two major segments on Nov. 25 at the agency’s Goddard Space Flight Center in Greenbelt, Md. The mission is slated to launch by May 2027, but the team is on track for launch as early as fall 2026.Credit: NASA/Jolearra Tshiteya“Completing the Roman observatory brings us to a defining moment for the agency,” said NASA Associate Administrator Amit Kshatriya. “Transformative science depends on disciplined engineering, and this team has delivered—piece by piece, test by test—an observatory that will expand our understanding of the universe. As Roman moves into its final stage of testing following integration, we are focused on executing with precision and preparing for a successful launch on behalf of the global scientific community.”
After final testing, Roman will move to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Roman is slated to launch by May 2027, but the team is on track for launch as early as fall 2026. A SpaceX Falcon Heavy rocket will send the observatory to its final destination a million miles from Earth.
“With Roman’s construction complete, we are poised at the brink of unfathomable scientific discovery,” said Julie McEnery, Roman’s senior project scientist at NASA Goddard. “In the mission’s first five years, it’s expected to unveil more than 100,000 distant worlds, hundreds of millions of stars, and billions of galaxies. We stand to learn a tremendous amount of new information about the universe very rapidly after Roman launches.”
NASA’s Nancy Grace Roman Space Telescope will survey vast swaths of sky during its five-year primary mission. During that time, scientists expect it to see an incredible number of new objects, including stars, galaxies, black holes and planets outside our solar system, known as exoplanets. This infographic previews some of the discoveries scientists anticipate from Roman’s data deluge. Credit: NASA’s Goddard Space Flight CenterObserving from space will make Roman very sensitive to infrared light — light with a longer wavelength than our eyes can see — from far across the cosmos. Pairing its crisp infrared vision with a sweeping view of space will allow astronomers to explore myriad cosmic topics, from dark matter and dark energy to distant worlds and solitary black holes, and conduct research that would take hundreds of years using other telescopes.
“Within our lifetimes, a great mystery has arisen about the cosmos: why the expansion of the universe seems to be accelerating. There is something fundamental about space and time we don’t yet understand, and Roman was built to discover what it is,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “With Roman now standing as a complete observatory, which keeps the mission on track for a potentially early launch, we are a major step closer to understanding the universe as never before. I couldn’t be prouder of the teams that have gotten us to this point.”
Double vision
Roman is equipped with two instruments: the Wide Field Instrument and the Coronagraph Instrument technology demonstration.
The coronagraph will demonstrate new technologies for directly imaging planets around other stars. It will block the glare from distant stars and make it easier for scientists to see the faint light from planets in orbit around them. The Coronagraph aims to photograph worlds and dusty disks around nearby stars in visible light to help us see giant worlds that are older, colder, and in closer orbits than the hot, young super-Jupiters direct imaging has mainly revealed so far.
“The question of ‘Are we alone?’ is a big one, and it’s an equally big task to build tools that can help us answer it,” said Feng Zhao, the Roman Coronagraph Instrument manager at NASA’s Jet Propulsion Laboratory in Southern California. “The Roman Coronagraph is going to bring us one step closer to that goal. It’s incredible that we have the opportunity to test this hardware in space on such a powerful observatory as Roman.”
The coronagraph team will conduct a series of pre-planned observations for three months spread across the mission’s first year-and-a-half of operations, after which the mission may conduct additional observations based on scientific community input.
The Wide Field Instrument is a 288-megapixel camera that will unveil the cosmos all the way from our solar system to near the edge of the observable universe. Using this instrument, each Roman image will capture a patch of the sky bigger than the apparent size of a full moon. The mission will gather data hundreds of times faster than NASA’s Hubble Space Telescope, adding up to 20,000 terabytes (20 petabytes) over the course of its five-year primary mission.
“The sheer volume of the data Roman will return is mind-boggling and key to a host of exciting investigations,” said Dominic Benford, Roman’s program scientist at NASA Headquarters.

Using the Wide Field Instrument, Roman will conduct three core surveys which will account for 75% of the primary mission. The High-Latitude Wide-Area Survey will combine the powers of imaging and spectroscopy to unveil more than a billion galaxies strewn across a wide swath of space and time. Astronomers will trace the evolution of the universe to probe dark matter — invisible matter detectable only by how its gravity affects things we can see — and trace the formation of galaxies and galaxy clusters over time.
The High-Latitude Time-Domain Survey will probe our dynamic universe by observing the same region of the cosmos repeatedly. Stitching these observations together to create movies will allow scientists to study how celestial objects and phenomena change over time periods of days to years. That will help astronomers study dark energy — the mysterious cosmic pressure thought to accelerate the universe’s expansion — and could even uncover entirely new phenomena that we don’t yet know to look for.
Roman’s Galactic Bulge Time-Domain Survey will look inward to provide one of the deepest views ever of the heart of our Milky Way galaxy. Astronomers will watch hundreds of millions of stars in search of microlensing signals — gravitational boosts of a background star’s light caused by the gravity of an intervening object. While astronomers have mainly discovered star-hugging worlds, Roman’s microlensing observations can find planets in the habitable zone of their star and farther out, including worlds like every planet in our solar system except Mercury. Microlensing will also reveal rogue planets—worlds that roam the galaxy untethered to a star — and isolated black holes. The same dataset will reveal 100,000 worlds that transit, or pass in front of, their host stars.
The remaining 25% of Roman’s five-year primary mission will be dedicated to other observations that will be determined with input from the broader scientific community. The first such program, called the Galactic Plane Survey, has already been selected.
Because Roman’s observations will enable such a wide range of science, the mission will have a General Investigator Program designed to support astronomers to reveal scientific discoveries using Roman data. As part of NASA’s commitment to Gold Standard Science, NASA will make all of Roman’s data publicly available with no exclusive use period. This ensures multiple scientists and teams can use data at the same time, which is important since every Roman observation will address a wealth of science cases.
NASA’s freshly assembled Nancy Grace Roman Space Telescope will revolutionize our understanding of the universe with its deep, crisp, sweeping infrared views of space. The mission will transform virtually every branch of astronomy and bring us closer to understanding the mysteries of dark energy, dark matter, and how common planets like Earth are throughout our galaxy. Roman is on track for launch by May 2027, with teams working toward a launch as early as fall 2026. Credit: NASA’s Goddard Space Flight CenterRoman’s namesake — Dr. Nancy Grace Roman, NASA’s first chief astronomer — made it her personal mission to make cosmic vistas readily accessible to all by paving the way for telescopes based in space.
“The mission will acquire enormous quantities of astronomical imagery that will permit scientists to make groundbreaking discoveries for decades to come, honoring Dr. Roman’s legacy in promoting scientific tools for the broader community,” said Jackie Townsend, Roman’s deputy project manager at NASA Goddard. “I like to think Dr. Roman would be extremely proud of her namesake telescope and thrilled to see what mysteries it will uncover in the coming years.”
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory in Southern California; Caltech/IPAC in Pasadena, California; the Space Telescope Science Institute in Baltimore; and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems Inc. in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

Student Art Murals at Johnson Celebrate 25 Years of Humanity in Space
Select walls at NASA’s Johnson Space Center have been transformed into works of art. Each piece reflects creativity, collaboration, and the spirit of discovery. Painted by Texas students, the murals honor the legacy of the International Space Station and 25 years of continuous human presence in space.
The International Space Station Program Mural Project began in 2022 as part of a broader effort to bring color and inspiration into the workplace while connecting classrooms to NASA’s mission.
“Dream Big,” created by Texas City High School students with the International Space Station Program Mission and Program Integration team in 2025, symbolizes imagination becoming exploration.“The mural collection is a reminder that today’s dreams can be tomorrow’s realities,” said Space Operations Mission Directorate Deputy Associate Administrator Joel Montalbano. “The future of space exploration depends on the imagination of our students.”
As NASA prepares for the next giant leap through Artemis, the art on the walls serves as a reminder that every mission begins with creativity and courage. This initiative continues to inspire the next generation to Dare | Unite | Explore. While art allows for interpretation, each mural required careful planning, communication, and problem-solving, just like the work behind human spaceflight.
The most recent mural, “Dream Big,” was installed in the hallway leading to the International Space Station Program suite on the fifth floor of building 1. Created by Texas City High School students with the International Space Station Program Mission Integration and Operations team, the artwork shows a grayscale child pulling back a curtain to reveal rockets, astronauts, and bright planetary landscapes.
The mural’s design draws from both classic and modern art influences. The students were inspired by Van Gogh’s impressionistic style and Banksy’s Behind the Curtain, combining movement and curiosity to reflect how imagination can open the door to exploration.
“The National Art Honor Society was honored to take on this inspiring project,” said Texas City High School art teacher Jennifer Massie. “They chose ‘Where Creativity Meets Reality’ to show how a child’s creative mind keeps moving and evolving—and that with big dreams and hard work, kids can follow in their heroes’ footsteps.”
What started as an idea between Gary Johnson, technical manager in the International Space Station Mission Integration and Operations Office, and Raul Tijerina, then the program’s building graphics lead, has grown into a gallery-sized initiative that bridges science and creativity.
“We want students to have the unique opportunity to contribute to NASA’s legacy through their artwork,” Johnson said. “These murals show that every mission begins with imagination and that the next generation of explorers is already helping paint humanity’s future among the stars.”
“Dream Explore Discover” was the first art mural created by Friendswood High School students in 2022.NASA/Bill StaffordTwo murals are now housed in the hallway of the Neutral Buoyancy Laboratory’s International Space Development Integration Laboratory, known as the SDIL. The first, “Dream Explore Discover,” created by Friendswood High School students, was originally displayed in building 4 south. Under the guidance of art teacher Mandy Harris, more than 30 students designed and painted the 8-by-18-foot mural, starting with sketches and brainstorming sessions that considered how art could reflect human space exploration. The students combined their ideas into a single design celebrating the beauty and excitement of discovery.
Elements of the mural include an astronaut’s visor reflecting the Houston skyline, zinnias symbolizing life and science connecting beyond Earth, and a small floating teddy bear representing both the dreams of children who look up to the stars and the generations of explorers who carried small tokens of home into space. It serves as a reminder of the human heart behind every mission.
The mural also features the launch of NASA’s SLS (Space Launch System) rocket with NASA’s Orion spacecraft riding on top, heading for the next giant leap in exploration. Beside the capsule, the Orion constellation appears in the sky, symbolizing how the stars continue to guide humanity’s journey to the Moon, Mars, and beyond.
“The Moon Now,” created by La Marque High School students, depicts two astronauts on the lunar surface in Axiom spacesuits with mirrored visors.“The Moon Now,” created by students from La Marque High School, Blocker Middle School, and Giles Middle School, is also housed at the SDIL. The artwork depicts two astronauts on the lunar surface wearing Axiom spacesuits with mirrored visors that reflect the faces of the next generation who will carry humanity back to the Moon. Individual student artworks of the Milky Way and celestial objects were collaged into the final piece, creating a tapestry of imagination and exploration.
Dickinson High School’s “A Starry Night” reimagines classic artistry through the lens of modern spaceflight.NASA/Josh ValcarcelThe remaining murals are installed in building 4 south at Johnson. In 2023, the program expanded to include Dickinson High School, whose students created “A Starry Night,” a blend of Renaissance-style painting and modern space imagery. “Everyone wanted to be involved,” said art teacher Jennifer Sumrall. “The kids loved it and did their own research on how each of NASA’s missions impacts the world.”

Three Martian dust devils can be seen near the rim of Jezero Crater in this short video made of images taken by a navigation camera aboard NASA’s Perseverance rover on Sept. 6, 2025. The microphone on the rover’s SuperCam previously captured audio when a dust devil passed over.NASA/JPL-Caltech/SSIPerseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters.
NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars.
A frequent occurrence on the Red Planet, dust devils form from rising and rotating columns of warm air. Air near the planet’s surface becomes heated by contact with the warmer ground and rises through the denser, cooler air above. As other air moves along the surface to take the place of the rising warmer air, it begins to rotate. When the incoming air rises into the column, it picks up speed like spinning ice skaters bringing their arms closer to their body. The air rushing in also picks up dust, and a dust devil is born.
SuperCam has recorded 55 distinct electrical events over the course of the mission, beginning on the mission’s 215thMartian day, or sol, in 2021. Sixteen have been recorded when dust devils passed directly over the rover.
Decades before Perseverance landed, scientists theorized that the friction generated by tiny dust grains swirling and rubbing against each other in Martian dust devils could generate enough of an electrical charge to eventually produce electrical arcs. Called the triboelectric effect, it’s the phenomenon at play when someone walks over a carpet in socks and then touches a metal doorknob, generating a spark. In fact, that is about the same level of discharge as what a Martian dust devil might produce.
“Triboelectric charging of sand and snow particles is well documented on Earth, particularly in desert regions, but it rarely results in actual electrical discharges,” said Baptiste Chide, a member of the Perseverance science team and a planetary scientist at L’Institut de Recherche en Astrophysique et Planétologie in France. “On Mars, the thin atmosphere makes the phenomenon far more likely, as the amount of charge required to generate sparks is much lower than what is required in Earth’s near-surface atmosphere.”
Perseverance’s SuperCam instrument carries a microphone to analyze the sounds of the instrument’s laser when it zaps rocks, but the team has also captured the sounds of wind and even the first audio recording of a Martian dust devil. Scientists knew it could pick up electromagnetic disturbance (static) and sounds of electrical discharges in the atmosphere. What they didn’t know was if such events happened frequently enough, or if the rover would ever be close enough, to record one. Then they began to assess data amassed over the mission, and it didn’t take long to find the telltale sounds of electrical activity.

“We got some good ones where you can clearly hear the ‘snap’ sound of the spark,” said coauthor Ralph Lorenz, a Perseverance scientist at the Johns Hopkins Applied Physics Lab in Laurel, Maryland. “In the Sol 215 dust devil recording, you can hear not only the electrical sound, but also the wall of the dust devil moving over the rover. And in the Sol 1,296 dust devil, you hear all that plus some of the particles impacting the microphone.”
Thirty-five other discharges were associated with the passage of convective fronts during regional dust storms. These fronts feature intense turbulence that favor triboelectric charging and charge separation, which occurs when two objects touch, transfer electrons, and separate — the part of the triboelectric effect that results in a spark of static electricity.
Researchers found electrical discharges did not seem to increase during the seasons when dust storms, which globally increase the presence of atmospheric dust, are more common on Mars. This result suggests that electrical buildup is more closely tied to the localized, turbulent lifting of sand and dust rather than high dust density alone.

The proof of these electrical discharges is a discovery that dramatically changes our understanding of Mars. Their presence means that the Martian atmosphere can become sufficiently charged to activate chemical reactions, leading to the creation of highly oxidizing compounds, such as chlorates and perchlorates. These strong substances can effectively destroy organic molecules (which constitute some of the components of life) on the surface and break down many atmospheric compounds, completely altering the overall chemical balance of the Martian atmosphere.
This discovery could also explain the puzzling ability of Martian methane to vanish rapidly, offering a crucial piece of the puzzle for understanding the constraints life may have faced and, therefore, the planet’s potential to be habitable.
Given the omnipresence of dust on Mars, the presence of electrical charges generated by particles rubbing together would seem likely to influence dust transport on Mars as well. How dust travels on Mars plays a central role in the planet’s climate but remains poorly understood.
Confirming the presence of electrostatic discharges will also help NASA understand potential risks to the electronic equipment of current robotic missions. That no adverse electrostatic discharge effects have been reported in several decades of Mars surface operations may attest to careful spacecraft grounding practices. The findings could also inform safety measures developed for future astronauts exploring the Red Planet.

Three Martian dust devils can be seen near the rim of Jezero Crater in this short video made of images taken by a navigation camera aboard NASA’s Perseverance rover on Sept. 6, 2025. The microphone on the rover’s SuperCam previously captured audio when a dust devil passed over.NASA/JPL-Caltech/SSIPerseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters.
NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars.
A frequent occurrence on the Red Planet, dust devils form from rising and rotating columns of warm air. Air near the planet’s surface becomes heated by contact with the warmer ground and rises through the denser, cooler air above. As other air moves along the surface to take the place of the rising warmer air, it begins to rotate. When the incoming air rises into the column, it picks up speed like spinning ice skaters bringing their arms closer to their body. The air rushing in also picks up dust, and a dust devil is born.

Hubble Seeks Clusters in ‘Lost Galaxy’
Hubble Seeks Clusters in ‘Lost Galaxy’
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname ‘Lost Galaxy’. With a mirror spanning nearly eight feet (2.4 meters) across and its location above Earth’s light-obscuring atmosphere, Hubble can easily observe dim galaxies like NGC 4535 and pick out features like its massive spiral arms and central bar of stars.
This image features NGC 4535’s young star clusters, which dot the galaxy’s spiral arms. Glowing-pink clouds surround many of these bright-blue star groupings. These clouds, called H II (‘H-two’) regions, are a sign that the galaxy is home to especially young, hot, and massive stars that blaze with high-energy radiation. Such massive stars shake up their surroundings by heating their birth clouds with powerful stellar winds, eventually exploding as supernovae.
The image incorporates data from an observing program designed to catalog roughly 50,000 H II regions in nearby star-forming galaxies like NGC 4535. Hubble released a previous image of NGC 4535 in 2021. Both the 2021 image and this new image incorporate observations from the PHANGS observing program, which seeks to understand the connections between young stars and cold gas. Today’s image adds a new dimension to our understanding of NGC 4535 by capturing the brilliant red glow of the nebulae that encircle massive stars in their first few million years of life.
