"The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy."

NASA Installs Heat Shield on First Private Spacecraft Bound for Venus

Thu, 02/27/2025 - 2:03pm
NASA/Brandon Torres Navarrete

Engineers at NASA’s Ames Research Center in California’s Silicon Valley, Bohdan Wesely, right, and Eli Hiss, left, complete a fit check of the two halves of a space capsule that will study the clouds of Venus for signs of life.

Led by Rocket Lab of Long Beach, California, and their partners at the Massachusetts Institute of Technology in Cambridge, Rocket Lab’s Venus mission will be the first private mission to the planet.

NASA’s role is to help the commercial space endeavor succeed by providing expertise in thermal protection of small spacecraft. Invented at Ames, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) – the brown, textured material covering the bottom of the capsule in this photo – is a woven heat shield designed to protect spacecraft from temperatures up to 4,500 degrees Fahrenheit. The probe will deploy from Rocket Lab’s Photon spacecraft bus, taking measurements as it descends through the planet’s atmosphere.

Teams at Ames work with private companies, like Rocket Lab, to turn NASA materials into solutions such as the heat shield tailor-made for this spacecraft destined for Venus, supporting growth of the new space economy. NASA’s Small Spacecraft Technology program, part of the agency’s Space Technology Mission Directorate, supported development of the heat shield for Rocket Lab’s Venus mission.

5 Min Read NASA’s Hubble Provides Bird’s-Eye View of Andromeda Galaxy’s Ecosystem

A view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away.

Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don’t see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive.

These satellite galaxies represent a rambunctious galactic “ecosystem” that NASA’s Hubble Space Telescope is studying in unprecedented detail. This ambitious Hubble Treasury Program used observations from more than a whopping 1,000 Hubble orbits. Hubble’s optical stability, clarity, and efficiency made this ambitious survey possible. This work included building a precise 3D mapping of all the dwarf galaxies buzzing around Andromeda and reconstructing how efficiently they formed new stars over the nearly 14 billion years of the universe’s lifetime.

This is a wide-angle view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away. The Hubble Space Telescope was used to study the entire population of 36 mini-galaxies circled in yellow. Andromeda is the bright spindle-shaped object at image center. All the dwarf galaxies seem to be confined to a plane, all orbiting in the same direction. The wide view is from ground-based photography. Hubble’s optical stability, clarity, and efficiency made this ambitious survey possible. Hubble close up snapshots of four dwarf galaxies are on image right. The most prominent dwarf galaxy is M32 (NGC 221), a compact ellipsoidal galaxy that might be the remnant core of a larger galaxy that collided with Andromeda a few billion years ago. NASA, ESA, Alessandro Savino (UC Berkeley), Joseph DePasquale (STScI), Akira Fujii DSS2

In the study published in The Astrophysical Journal, Hubble reveals a markedly different ecosystem from the smaller number of satellite galaxies that circle our Milky Way. This offers forensic clues as to how our Milky Way galaxy and Andromeda have evolved differently over billions of years. Our Milky Way has been relatively placid. But it looks like Andromeda has had a more dynamic history, which was probably affected by a major merger with another big galaxy a few billion years ago. This encounter, and the fact that Andromeda is as much as twice as massive as our Milky Way, could explain its plentiful and diverse dwarf galaxy population.

Surveying the Milky Way’s entire satellite system in such a comprehensive way is very challenging because we are embedded inside our galaxy. Nor can it be accomplished for other large galaxies because they are too far away to study the small satellite galaxies in much detail. The nearest galaxy of comparable mass to the Milky Way beyond Andromeda is M81, at nearly 12 million light-years.

This bird’s-eye view of Andromeda’s satellite system allows us to decipher what drives the evolution of these small galaxies. “We see that the duration for which the satellites can continue forming new stars really depends on how massive they are and on how close they are to the Andromeda galaxy,” said lead author Alessandro Savino of the University of California at Berkeley. “It is a clear indication of how small-galaxy growth is disturbed by the influence of a massive galaxy like Andromeda.”

“Everything scattered in the Andromeda system is very asymmetric and perturbed. It does appear that something significant happened not too long ago,” said principal investigator Daniel Weisz of the University of California at Berkeley. “There’s always a tendency to use what we understand in our own galaxy to extrapolate more generally to the other galaxies in the universe. There’s always been concerns about whether what we are learning in the Milky Way applies more broadly to other galaxies. Or is there more diversity among external galaxies? Do they have similar properties? Our work has shown that low-mass galaxies in other ecosystems have followed different evolutionary paths than what we know from the Milky Way satellite galaxies.”

For example, half of the Andromeda satellite galaxies all seem to be confined to a plane, all orbiting in the same direction. “That’s weird. It was actually a total surprise to find the satellites in that configuration and we still don’t fully understand why they appear that way,” said Weisz.

This animation begins with a view of the neighboring Andromeda galaxy. We zoom through a scattering of foreground stars and enter the inky blackness of intergalactic space. We cross 2.5 million light-years to reach the Andromeda system, consisting of 36 dwarf satellite galaxies orbiting the giant spindle-shaped Andromeda galaxy at image center. An ambitious survey by the Hubble Space Telescope was made to plot the galaxy locations in three-dimensional space. In this video we circle around a model of the Andromeda system based on real Hubble observational data.

The brightest companion galaxy to Andromeda is Messier 32 (M32). This is a compact ellipsoidal galaxy that might just be the remnant core of a larger galaxy that collided with Andromeda a few billion years ago. After being gravitationally stripped of gas and some stars, it continued along its orbit. Galaxy M32 contains older stars, but there is evidence it had a flurry of star formation a few billion years ago. In addition to M32, there seems to be a unique population of dwarf galaxies in Andromeda not seen in the Milky Way. They formed most of their stars very early on, but then they didn’t stop. They kept forming stars out of a reservoir of gas at a very low rate for a much longer time.

“Star formation really continued to much later times, which is not at all what you would expect for these dwarf galaxies,” continued Savino. “This doesn’t appear in computer simulations. No one knows what to make of that so far.”

“We do find that there is a lot of diversity that needs to be explained in the Andromeda satellite system,” added Weisz. “The way things come together matters a lot in understanding this galaxy’s history.”

Hubble is providing the first set of imaging where astronomers measure the motions of the dwarf galaxies. In another five years Hubble or NASA’s James Webb Space Telescope will be able to get the second set of observations, allowing astronomers to do a dynamical reconstruction for all 36 of the dwarf galaxies, which will help astronomers to rewind the motions of the entire Andromeda ecosystem billions of years into the past.

The Hubble Space Telescope has been operating for over three decades and 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.

NASA Selects Participating Scientists to Join Lucy Asteroid Mission

NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early solar system trapped on stable orbits associated with — but not close to — the planet Jupiter. 

NASA’s Lucy mission, shown in this artist’s concept, is the first mission to explore the Jupiter Trojan asteroids.

NASA’s Lucy in the L4 Trojans Participating Scientist Program supports scientists to carry out new investigations that address outstanding questions related to the Jupiter Trojan asteroids as part of the Lucy mission. Launched in 2021, the Lucy spacecraft is currently on its way to the L4 Trojan swarm, which leads Jupiter in its orbit around the Sun. This is the first selection of Lucy participating scientists, who will become mission science team members for the four major asteroid encounters that the Lucy spacecraft will have in the L4 swarm in 2027 and 2028, and who will remain on the team for subsequent scientific analysis until 2030. 

The newly selected participating scientists are:

  • Harrison Agrusa, Observatoire de la Côte d’Azur in Nice, France
  • Benjamin Byron, University of Central Florida in Orlando
  • Emily Costello, University of Hawaii, Honolulu
  • Masatoshi Hirabayashi, Georgia Tech Research Corporation in Atlanta
  • Fiona Nichols-Fleming, Smithsonian Institution in Washington
  • Norbert Schorghofer, Planetary Science Institute in Tucson, Arizona
  • Jennifer Scully, NASA’s Jet Propulsion Laboratory in Southern California
  • Anne Verbiscer, University of Virginia, Charlottesville

Lucy’s principal investigator, Hal Levison, is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built and operates the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program.

Liftoff! NASA Tech, Science En Route to Moon with Intuitive Machines

Thu, 02/27/2025 - 9:49am

Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Intuitive Machines’ Nova-C lunar lander (IM-2) and NASA’s Lunar Trailblazer soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 7:16 p.m. EST, Wednesday, Feb. 26. The IM-2 launch, which is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, is carrying NASA technology and science demonstrations, and other commercial payloads to Mons Mouton, a lunar plateau to advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions.

The next set of NASA science and technology demonstrations is on its way to the lunar surface, where they will gather data about Earth’s nearest neighbor and help pave the way for American astronauts to explore the Moon and beyond, for the benefit of all.

Carrying NASA instruments as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines’ IM-2 mission launched at 7:16 p.m. EST, Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Intuitive Machines’ lunar lander is scheduled to touch down on Thursday, March 6, in Mons Mouton, a plateau in the Moon’s South Pole.

“With each CLPS mission, the United States is leading the way in expanding our reach and refining our capabilities, turning what was once dreams into reality,” said NASA acting Administrator Janet Petro. “These science and technology demonstrations are more than payloads – they represent the foundation for future explorers who will live and work on the Moon. By partnering with American industry, we are driving innovation, strengthening our leadership in space, and preparing for sending humans farther into the solar system, including Mars.”

Once on the Moon, the NASA CLPS investigations will aim to measure the potential presence of volatiles or gases from lunar soil – one of the first on-site demonstrations of resource use on the Moon. In addition, a passive Laser Retroreflector Array on the top deck of the lander will bounce laser light back at any future orbiting or incoming spacecraft to give them a permanent reference point on the lunar surface. Other technology instruments on this delivery will demonstrate a robust surface communications system and deploy a propulsive drone designed to hop across the lunar surface.

NASA’s Lunar Trailblazer spacecraft, which launched as a rideshare with the IM-2 mission, also began its journey to lunar orbit, where it will map the distribution of the different forms of water on the Moon. Lunar Trailblazer will discover where the Moon’s water is, what form it is in, and how it changes over time. Observations gathered during its two-year prime mission will contribute to the understanding of water cycles on airless bodies throughout the solar system while also supporting future human and robotic missions to the Moon by identifying where water is located. 

NASA’s Artemis campaign includes conducting more science to better understand planetary processes and evolution, to search for evidence of water and other resources, and support long-term, sustainable human exploration.

The NASA science and technology instruments that launched aboard the IM-2 mission are:

  • Polar Resources Ice Mining Experiment-1 (PRIME-1): This experiment will explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate the ability to extract and analyze lunar soil to detect volatile chemical compounds that turn into gas. The two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to better understand the Moon’s surface and how to work with and on it.
  • Laser Retroreflector Array (LRA): This collection of eight retroreflectors will enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The LRA is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come.   
  • Micro Nova Hopper: Funded by NASA’s Space Technology Mission Directorate Tipping Point initiative, Intuitive Machines’ Micro Nova hopper, Grace, is designed to enable high-resolution surveying of the lunar surface under its flight path. This autonomous propulsive drone aims to deploy to the surface and hop into a nearby crater to survey the lunar surface and send science data back to the lander. It’s designed to hop in and out of a permanently shadowed region, providing a first look into undiscovered regions that may provide critical information to sustain a human presence on the Moon.
  • Nokia Lunar Surface Communications System (LSCS): Also developed with funding from NASA’s Tipping Point initiative, Nokia’s LSCS 4G/LTE communications system will demonstrate cellular communications between the Intuitive Machines lander, a Lunar Outpost rover, and the Micro Nova hopper. Engineered to transmit high-definition video, command-and-control messages, and sensor and telemetry data, the LSCS aims to demonstrate an ultra-compact advanced communication solution for future infrastructure on the Moon and beyond.

Sols 4466-4468: Heading Into the Small Canyon

Wed, 02/26/2025 - 9:31pm
Curiosity Navigation

4 min read

Sols 4466-4468: Heading Into the Small Canyon NASA’s Mars rover Curiosity produced this image from its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm. This image is a combination of two MAHLI images, merged on the rover on Feb. 25, 2025 — sol 4464, or Martian day 4,464 of the Mars Science Laboratory mission — at 22:36:53 UTC. NASA/JPL-Caltech/MSSS

Written by Susanne Schwenzer, Planetary Geologist at The Open University

Earth planning date: Wednesday, Feb. 26, 2025

The fine detail of the image above reminds us once again that geoscience — on Mars and on Earth — is an observational science. If you look at the image for a few moments, you will see that there are different areas made of different textures. You will also observe that some features appear to be more resistant to weathering than others, and as a consequence stand out from the surface or the rims of the block. Sedimentologists will study this and many other images in fine detail and compare them to similar images we have acquired along the most recent drive path. From that they put together a reconstruction of the environment billions of years in the past: Was it water or wind that laid down those rocks, and what happened next? Many of the knobbly textures might be from water-rock interaction that happened after the initial deposition of the material. We will see; the jury is out on what these details tell us, and we are looking closely at all those beautiful images and then will turn to the chemistry data to understand even more about those rocks.

In the caption of the image above it says “merged” images. This is an imaging process that happens aboard the rover — it takes two (or more) images of the same location on the same target, acquired at different focus positions, and merges them so a wider range of the rock is in focus. This is especially valuable on textures that have a high relief, such as the above shown example. The rover is quite clever, isn’t it?

In today’s plan MAHLI does not have such an elaborate task, but instead it is documenting the rock that the APXS instrument is measuring. The team decided that it is time for APXS to measure the regular bedrock again, because we are driving out of an area that is darker on the orbital image and into a lighter area. If you want, you can follow our progress on that orbital image. (But I am sure many of the regular readers of this blog know that!)

That bedrock target was named “Trippet Ranch.” ChemCam investigates the target “San Ysidro Trail,” which is a grayish-looking vein. As someone interested in water-rock interactions for my research, I always love plans that have the surrounding rock (the APXS target in this case) and the alteration features in the same location. This allows us to tease out which of the chemical components of the rock might have moved upon contact with water, and which ones have not.

As we are driving through very interesting terrain, with walls exposed on the mesas — especially Gould mesa — and lots of textures in the blocks around us, there are many Mastcam mosaics in today’s plan! The mosaics on “Lytle Creek,” “Round Valley,” “Heaton Flat,” “Los Liones,” and the single image on “Mount Pinos” all document this variety of structures, and another mosaic looks right at our workspace. It did not get a nice name as it is part of a series with a more descriptive name all called “trough.” We often do this to keep things together in logical order when it comes to imaging series. The long-distance RMIs in today’s plan are another example of this, as they are just called “Gould,” followed by the sol number they will be taken on — that’s 4466 — and a and b to distinguish the two from each other. Gould Mesa, the target of both of them, exposes many different structures and textures, and looking at such walls — geologists call them outcrops — lets us read the rock record like a history book! And it will get even better in the next few weeks as we are heading into a small canyon and will have walls on both sides. Lots of science to come in the next few downlinks, and lots of science on the ground already! I’d better get back to thinking about some of the data we have received recently, while the rover is busy exploring the ever-changing geology and mineralogy on the flanks of Mount Sharp.

NASA Remembers Long-Time Civil Servant John Boyd

Wed, 02/26/2025 - 5:45pm
Portrait of John Boyd, whose contributions to NASA spanned more than 70 years.Credit: NASA

John Boyd, known to many as Jack and whose career spanned more than seven decades in a multitude of roles across NASA as well as its predecessor, the National Advisory Committee for Aeronautics (NACA), died Feb. 20. He was 99. Born in 1925, and raised in Danville, Virginia, he was a long-time resident of Saratoga, California.

Boyd is being remembered by many across the agency, including Dr. Eugene Tu, director, NASA’s Ames Research Center in California’s Silicon Valley, where Boyd spent most of his career.

“Jack brought an energy, optimism, and team-based approach to solving some of the greatest technological challenges humanity has ever faced, which remains part of our culture to this day,” said Tu. “There are few careers as wide-ranging and impactful as Jack’s.”

In 1947, Boyd began his career at the then-called Ames Aeronautical Laboratory in Moffett Field, California, as an aeronautical engineer working to design and test various wing shapes using the center’s 1-by-3-foot supersonic wind tunnel. Boyd continued conducting research in wind tunnels, testing designs that led to dramatic increases in the efficiency of the supersonic B-58 bomber, as well as the F-102 and F-106 fighters.

In 1958, just before Ames became part of a newly established NASA, Boyd recalled thinking, “Maybe someday we’ll go out into the far blue yonder, and if we do, what are we going to fly? How are we going to bring it back into the atmosphere safely?” He and a team of engineers turned their attention to studying the dynamics of high-speed projectiles in hypervelocity ranges, filled with different mixtures of gases to mimic the atmospheres of Mars and Venus, in preparation for sending spacecraft out into space and safely back again or to the surface of other worlds.

By the mid-60s, Boyd was promoted into leadership and tapped to become deputy director for Aeronautics and Flight Systems at NASA Ames. In the late 1960s, as America was redefining its space exploration goals and sending humans to the Moon, Boyd served as the center’s lead to assist NASA Headquarters in Washington consolidate and create new research programs.

In 1979, Boyd served as the deputy director at NASA’s Dryden Flight Research Center (now known as NASA’s Armstrong Flight Research Center) in Edwards, California, and prepared the center for its role as a landing site for the space shuttle. He briefly returned to Ames before heading to NASA Headquarters to be associate administrator for management under James M. Beggs. Boyd left government service in 1985, taking a position as chancellor for research and an adjunct professor of aerodynamics, engineering, and the history of spaceflight for the University of Texas System.

Boyd returned to NASA and California’s Silicon Valley in 1993, inspiring students through educational outreach initiatives, and serving as the senior advisor to the director, senior advisor for history, and the center ombudsman until his retirement in 2020.

Boyd credits his interest in airplanes to a cousin who was a paratrooper and gave him a ride in a biplane in the 1940s. In 1943, he enrolled and became the first in his family to earn a degree with a bachelor of science in aeronautical engineering from Virginia Polytechnic Institute and State University in Blacksburg, Virginia. He was a recipient of the NASA Exceptional Service Award, the NASA Outstanding Leadership Award, the NASA Equal Employment Opportunity Medal, the Presidential Rank of Meritorious Executive, the NASA Distinguished Service Medal, the Army Command Medal, and the NASA Headquarters History Award. He also was a Fellow of the American Institute of Aeronautics and Astronautics and a Sloan Fellow at Stanford University.

“The agency and the nation thank and honor Jack as a member of the NASA family and the highest exemplar of a public servant who believed investing in others is the greatest contribution one can make,” added Tu. “He will be deeply missed.”

Fourth Launch of NASA Instruments Planned for Near Moon’s South Pole

Wed, 02/26/2025 - 5:39pm
A SpaceX Falcon 9 rocket stands vertical on Tuesday, Feb. 25, 2025, at Launch Complex 39A at NASA’s Kennedy Space Center ahead of Intuitive Machines’ IM-2 mission as part of the agency’s Commercial Lunar Payload Services initiative and Artemis campaign. SpaceX

Sending instruments to the Moon supports a growing lunar economy on and off Earth, and the next flight of NASA science and technology is only days away. NASA’s CLPS (Commercial Lunar Payload Services) initiative is a lunar delivery service that sends NASA science and technology instruments to various geographic locations on the Moon using American companies. These rapid, cost-effective commercial lunar missions at a cadence of about two per year improve our understanding of the lunar environment in advance of future crewed missions to the Moon as part of the agency’s broader Artemis campaign.  

Of the 11 active CLPS contracts, there have been three CLPS launches to date: Astrobotic’s Peregrine Mission One, which collected data in transit but experienced an anomaly that prevented it from landing on the Moon; Intuitive Machines’ IM-1 mission, which landed, tipped over, and operated on the lunar surface; and Firefly Aerospace’s Blue Ghost Mission One that is currently enroute and scheduled to land in early March 2025. The CLPS contract awards cover end-to-end commercial payload delivery services, including payload integration, launch from Earth, landing on the surface of the Moon, and mission operations. 

NASA’s fourth CLPS flight is from Intuitive Machines with their IM-2 mission. The IM-2 mission is carrying NASA science and technology instruments to Mons Mouton, a lunar plateau just outside of 5 degrees of the South Pole of the Moon, closer to the pole than any preceding lunar mission.  

Scheduled to launch no earlier than Wednesday and land approximately eight days later, Intuitive Machines’ Nova-C lander, named Athena, will carry three NASA instruments to the lunar South Pole region – the Polar Resources Ice Mining Experiment-1 (PRIME-1) suite and the Laser Retroreflector Array (LRA). 

The PRIME-1 suite consists of two instruments, the TRIDENT drill (The Regolith Ice Drill for Exploring New Terrain) and MSolo (Mass Spectrometer observing lunar operations), which will work together to extricate lunar soil samples, known as regolith, from the subsurface and analyze their composition to further understand the lunar environment and gain insight on potential resources that can be extracted for future examination. 

The meter-long TRIDENT drill is designed to extract lunar regolith, up to about three feet below the surface. It will also measure soil temperature at varying depths below the surface, which will help to verify existing lunar thermal models that are used for ice stability calculations and resource mapping. By drilling into the lunar regolith, information is gathered to help answer questions about the lunar regolith geotechnical properties, such as soil strength, both at the surface and in the subsurface that will help inform Artemis infrastructure objectives. The data will be beneficial when designing future systems for on-site resource utilization that will use local resources to create everything from landing pads to rocket fuel. The lead development organization for TRIDENT is Honeybee Robotics, a Blue Origin Company. 

The MSOLO instrument is a mass spectrometer capable of identifying and quantifying volatiles (or gasses that easily evaporate) found at or beneath the lunar surface, including– if it’s present in the regolith within the drill’s reach – water and oxygen, brought to the surface by the TRIDENT drill. This instrument can also detect any gases that emanate from the lander, drilling process, and other payloads conducting operations on the surface. Using MSolo to study the volatile gases found on the Moon can help us understand how the lander’s presence might alter the local environment. The lead development organization is INFICON of Syracuse, New York, in partnership with NASA’s Kennedy Space Center in Florida. 

NASA’s LRA is a collection of eight retroreflectors that enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The LRA instrument is passive, meaning it does not power on. It will function as a permanent location marker on the Moon for decades to come, similar to its predecessors. The lead development organization is NASA’s Goddard Space Flight Center in Greenbelt, Maryland. 

In addition to the CLPS instruments, two technology demonstrations aboard IM-2 were developed through NASA’s Tipping Point opportunity. These are collaborations with the agency’s Space Technology Mission Directorate and industry that support development of commercial space capabilities and benefit future NASA missions.  

Intuitive Machines developed a small hopping robot, Grace, named after Grace Hopper, computer scientist and mathematician. Grace will deploy as a secondary payload from the lander and enable high-resolution imaging and science surveying of the lunar surface, including permanently shadowed craters around the landing site. Grace is designed to bypass obstacles such as steep inclines, boulders, and craters to cover a lot of terrain while moving quickly, which is a valuable capability to support future missions on the Moon and other planets, including Mars. 

Nokia will test a Lunar Surface Communications System that employs the same cellular technology here on Earth. Reconceptualized by Nokia Bell Labs to meet the unique requirements of a lunar mission, this tipping point technology aims to demonstrate proximity communications between the lander, a Lunar Outpost rover, and the hopper. 

Launching as a rideshare alongside the IM-2 mission, NASA’s Lunar Trailblazer spacecraft also will begin its journey to lunar orbit where it will map the distribution of water – and other forms of water – on the Moon. 

Future CLPS flights will continue to send payloads to the near side, far side, and South Pole regions of the Moon where investigations and exploration are informed by each area’s unique characteristics. With a pool of 13 American companies under CLPS, including a portfolio of 11 lunar deliveries by five vendors sending more than 50 individual science and technology instruments to lunar orbit and the surface of the Moon, NASA continues to advance long-term exploration of the Moon, and beyond to Mars.

Sols 4464-4465: Making Good Progress NASA’s Mars rover Curiosity acquired this image using its Front Hazard Avoidance Camera (Front Hazcam) on Feb. 23, 2025 — sol 4462, or Martian day 4,462 of the Mars Science Laboratory mission — at 21:43:37 UTC. NASA/JPL-Caltech

Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center

Earth planning date: Monday, Feb. 24, 2025

Over the weekend Curiosity drove about 48 meters (about 157 feet) to the southwest, continuing to march along on our traverse past Texoli butte and Gould Mesa. I was on shift as the LTP today, and it was great to see the good drive progress, interesting workspace, and exciting stratigraphy that lies ahead.

Today’s two-sol plan includes contact science and a drive on the first sol, followed by untargeted remote sensing on the second sol. The Geology theme group got straight to work evaluating contact science targets, and decided on a nodular block named “Matilija Poppy” for APXS and MAHLI observations. Then the team turned their attention to the remote sensing activities. There are a variety of interesting rock textures near the rover, so the team spent some time planning Mastcam imaging and ChemCam LIBS activities to assess the diversity. Some blocks have polygonal fractures with raised ridges, while other blocks are more nodular or well-laminated. In addition to looking at the bedrock, Mastcam will document local troughs in the loose sand between blocks, to understand more recent surface processes. The team planned a ChemCam LIBS observation on one of the polygonal fractures at a target named “East Fork” and two long-distance ChemCam RMI mosaics of Gould Mesa to assess the distant stratigraphy. Then Curiosity will drive about 30 meters (about 98 feet) further to the south, and take post-drive imaging to prepare for Wednesday’s plan.

On the second sol Curiosity will take an autonomously selected ChemCam target, along with multiple environmental monitoring observations to search for dust devils, monitor atmospheric dust, and evaluate clouds. It was a pretty smooth day of planning, and it’s always nice to see how the team works together to accomplish a lot of great science. Looking forward to continuing to make great progress as we start climbing uphill again!

6 Things to Know About NASA’s Lunar Trailblazer

Wed, 02/26/2025 - 4:25pm

5 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) Sunlight gleams off NASA’s Lunar Trailblazer as the dishwasher-size spacecraft orbits the Moon in this artist’s concept. The mission will discover where the Moon’s water is, what form it is in, and how it changes over time, producing the best-yet maps of water on the lunar surface.Lockheed Martin Space

The small satellite mission will map the Moon to help scientists better understand where its water is, what form it’s in, how much is there, and how it changes over time.

Launching no earlier than Wednesday, Feb. 26, NASA’s Lunar Trailblazer will help resolve an enduring mystery: Where is the Moon’s water? After sharing a ride on a SpaceX Falcon 9 rocket with Intuitive Machines’ IM-2 launch — part of NASA’s CLPS (Commercial Lunar Payload Services) initiative — the small satellite will take several months to arrive in lunar orbit.

Here are six things to know about the mission.

1. Lunar Trailblazer will produce high-resolution maps of water on the lunar surface.

One of the biggest lunar discoveries in recent decades is that the Moon’s surface has quantities of water, but little about its nature is known. To investigate, Lunar Trailblazer will decipher where the water is, what form it is in, how much is there, and how it changes over time. The small satellite will produce the best-yet maps of water on the lunar surface. Observations gathered during the two-year prime mission will also contribute to the understanding of water cycles on airless bodies throughout the solar system.

2. The small satellite will use two state-of-the-art science instruments.

Key to achieving these goals are the spacecraft’s two science instruments: the High-resolution Volatiles and Minerals Moon Mapper (HVM3) infrared spectrometer and the Lunar Thermal Mapper (LTM) infrared multispectral imager. NASA’s Jet Propulsion Laboratory in Southern California provided the HVM3 instrument, while LTM was built by the University of Oxford and funded by the UK Space Agency.  

HVM3 will detect and map the spectral fingerprints, or wavelengths of reflected sunlight, of minerals and the different forms of water on the lunar surface. The LTM instrument will map the minerals and thermal properties of the same landscape. Together they will create a picture of the abundance, location, and form of water while also tracking how its distribution changes over time and temperature.

Fueled and attached to an adaptor used for secondary payloads, NASA’s Lunar Trailblazer is seen at SpaceX’s payload processing facility within NASA’s Kennedy Space Center in Florida in early February 2025. The small satellite is riding along on Intuitive Machines’ IM-2 launch.SpaceX 3. Lunar Trailblazer will take a long and winding road to the Moon.

Weighing only 440 pounds (200 kilograms) and measuring 11.5 feet (3.5 meters) wide with its solar panels fully deployed, Lunar Trailblazer is about the size of a dishwasher and relies on a relatively small propulsion system. To make the spacecraft’s four-to-seven-month trip to the Moon (depending on the launch date) as efficient as possible, the mission’s design and navigation team has planned a looping trajectory that will use the gravity of the Sun, Earth, and Moon to guide Lunar Trailblazer to its final science orbit — a technique called low-energy transfer.

4. The spacecraft will peer into the darkest parts of the Moon’s South Pole.

Lunar Trailblazer’s science orbit positions it to peer into the craters at the Moon’s South Pole using the HVM3 instrument. What makes these craters so intriguing is that they harbor cold traps that may not have seen direct sunlight for billions of years, which means they’re a potential hideout for frozen water. The HVM3 spectrometer is designed to use faint reflected light from the walls of craters to see the floor of even permanently shadowed regions. If Lunar Trailblazer finds significant quantities of ice at the base of the craters, those locations could be pinpointed as a resource for future lunar explorers.

5. Lunar Trailblazer is a high-risk, low-cost mission.

Lunar Trailblazer was a 2019 selection of NASA’s SIMPLEx (Small Innovative Missions for Planetary Exploration), which provides opportunities for low-cost science spacecraft to ride-share with selected primary missions. To maintain a lower overall cost, SIMPLEx missions have a higher risk posture and lighter requirements for oversight and management. This higher risk acceptance allows NASA to enable science missions that could not otherwise be done.

6. Future missions will benefit from Lunar Trailblazer’s data.

Mapping the Moon’s water supports future human and robotic lunar missions. With knowledge from Lunar Trailblazer of where water is located, astronauts could process lunar ice to create water for human use, breathable oxygen, or fuel. And they could conduct science by sampling the ice for later study to determine the water’s origins.

More About Lunar Trailblazer

Lunar Trailblazer is led by Principal Investigator Bethany Ehlmann of Caltech in Pasadena, California. Caltech also leads the mission’s science investigation, and Caltech’s IPAC leads mission operations, which includes planning, scheduling, and sequencing of all spacecraft activities. NASA JPL manages Lunar Trailblazer and provides system engineering, mission assurance, the HVM3 instrument, and mission design and navigation. JPL is managed by Caltech for NASA. Lockheed Martin Space provided the spacecraft, integrated the flight system, and supports operations under contract with Caltech. The University of Oxford developed and provided the LTM instrument, funded by the UK Space Agency. Lunar Trailblazer, part of NASA’s Lunar Discovery Exploration Program, is managed by NASA’s Planetary Mission Program Office at Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

NASA Open Data Turns Science Into Art

NASA Open Data Turns Science Into Art Guests enjoy Beyond the Light, a digital art experience featuring open NASA data, at ARTECHOUSE in Washington, D.C. on September 19, 2023. NASA/Wade Sisler

An art display powered by NASA science data topped the Salesforce Tower in San Francisco, CA throughout December 2024. Nightly visitors enjoyed “Synchronicity,” a 20-minute-long video art piece by Greg Niemeyer, which used a year’s worth of open data from NASA satellites and other sources to bring the rhythms of the Bay Area to life.

Data for “Synchronicity” included atmospheric data from NASA and NOAA’s GOES (Geostationary Operational Environmental Satellites), vegetation health data from NASA’s Landsat program, and the Sun’s extreme ultraviolet wavelengths as captured by the NASA and ESA (European Space Agency) satellite SOHO (Solar and Heliospheric Observatory). Chelle Gentemann, the program scientist for the Office of the Chief Science Data Officer within NASA’s Science Mission Directorate, advised Niemeyer on incorporating data into the piece.

Greg Niemeyer’s “Synchronicity” was displayed on Salesforce Tower in San Francisco, CA, in December 2024. A recording of the piece on the tower’s display and the original animation are shown here. The video art piece was created using open NASA data, as well as buoy data from the National Oceanographic and Atmospheric Administration (NOAA). Greg Niemeyer/Emma Strebel

“Artists have a lot to contribute to science,” Gentemann said. “Not only can they play a part in the actual scientific process, looking at things in a different way that will lead to new questions, but they’re also critical for getting more people involved in science.”

NASA’s history of engaging with artists goes back to the 1962 launch of the NASA Art Program, which partnered with artists in bringing the agency’s achievements to a broader audience and telling the story of NASA in a different and unexpected way. Artists such as Andy Warhol, Norman Rockwell, and Annie Leibovitz created works inspired by NASA missions. The Art Program was relaunched in September 2024 with a pair of murals evoking the awe of space exploration for the Artemis Generation.

The inaugural murals for the relaunched NASA Art Program appear side-by-side at 350 Hudson Street, Monday, Sept. 23, 2024, in New York City. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. NASA/Joel Kowsky

The use of NASA data in art pieces emerged a few decades after the NASA Art Program first launched. Several in-house agency programs, such as NASA’s Scientific Visualization Studio, create stunning animated works from science data. In the realm of audio, NASA’s Chandra X-ray Observatory runs the Universe of Sound project to convert astronomy data into “sonifications” for the public’s listening pleasure.

Collaborations with external artists help bring NASA data to an even broader audience. NASA’s commitment to open science – making it as easy as possible for the public to access science data – greatly reduces the obstacles for creatives looking to fuse their art with cutting-edge science.

Another recent blend of NASA data and art came when digital art gallery ARTECHOUSE created “Beyond the Light,” a 26-minute immersive video experience featuring publicly available images from the James Webb Space Telescope and Hubble Space Telescope. The experience has been running at various ARTECHOUSE locations since September 2023. The massive potential for art to incorporate science data promises to fuel even more of these collaborations between NASA and artists in the future.

“One of the integral values of open science is providing opportunities for more people to participate in science,” Gentemann said. “I think that by getting the public interested in how this art is done, they also are starting to play with scientific data, maybe for the first time. In that way, art has the power to create new scientists.”

NASA’s X-59 Completes Electromagnetic Testing

Tue, 02/25/2025 - 6:48pm

3 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s F-15D research aircraft is positioned adjacent to the X-59 during electromagnetic compatibility testing at U.S. Air Force Plant 42 in Palmdale, California. Researchers activated the F-15D’s radar, C-band transponder, and radios at different distances from the X-59 to evaluate potential electromagnetic interference with the aircraft’s flight-critical systems, ensuring the X-59 can operate safely with other aircraft. These tests showed that the aircraft’s integration is maturing and cleared a major hurdle that moves it one step closer to first flight.NASA/Carla Thomas

NASA’s quiet supersonic X-59 research aircraft has cleared electromagnetic testing, confirming its systems will work together safely, without interference across a range of scenarios.

“Reaching this phase shows that the aircraft integration is advancing,” said Yohan Lin, NASA’s X-59 avionics lead. “It’s exciting to see the progress, knowing we’ve cleared a major hurdle that moves us closer to X-59’s first flight.”

Electromagnetic interference occurs when an electric or magnetic field source affects an aircraft’s operations, potentially impacting safety. This interference, whether from an external source or the aircraft’s own equipment, can disrupt the electronic signals that control critical systems – similar to effects that lead to static or crackling on a radio from a nearby emitting device, like a phone.

The tests, conducted at contractor Lockheed Martin Skunk Works’ facility in Palmdale, California, ensured that the X-59’s onboard systems – such as radios, navigation equipment, and sensors – did not interfere with one another or cause unexpected problems. During these tests, engineers activated each system on the aircraft one at a time while they monitored the other systems for possible interference.

NASA’s X-59 quiet supersonic research aircraft successfully completed electromagnetic interference (EMI) testing at Lockheed Martin Skunk Works in Palmdale, California. During EMI tests, the team examined each of the X-59’s internal electronic systems, ensuring they worked with one another without interference. The X-59 is designed to fly faster than the speed of sound while reducing the loud sonic boom to a quieter sonic thump.NASA/Carla Thomas

“This testing helped us determine whether the systems within the X-59 are interfering with each other,” Lin said. “It’s called a source-victim test – essentially, we activate one system and monitor the other for issues like noise, glitches, faults, or errors.”

The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA’s Quesst mission, which will provide regulators with information that could help lift current bans on commercial supersonic flight over land. Currently, the aircraft is progressing through ground tests to ensure safety and performance. These included the recent, successful completion of a set of engine tests. The electromagnetic interference testing to examine the X-59’s internal electronic systems followed.

Other electromagnetic interference testing involved the team looking at the operation of the X-59’s landing gear, ensuring this critical component can extend and retract without affecting other systems. And they tested that the fuel switch shutoff was functioning properly without interference.

Electromagnetic compatibility was also assessed during this testing – making sure the X-59’s systems will function properly when it eventually flies near NASA research aircraft.

NASA test pilot Jim Less prepares to exit the cockpit of the quiet supersonic X-59 aircraft in between electromagnetic interference (EMI) testing. The EMI testing ensures an aircraft’s systems function properly under various conditions of electromagnetic radiation. The X-59 is the centerpiece of the NASA’s Quesst mission, designed to demonstrate quiet supersonic technology and provide data to address a key barrier to commercial supersonic travel.NASA/Carla Thomas

Researchers staged the X-59 on the ground in front of NASA’s F-15D, placing them 47 feet apart, then 500 feet apart. The proximity of the two aircraft replicated conditions needed for the F-15D to use a special probe to gather measurements about the shock waves the X-59 will produce.

“We want to confirm there’s compatibility between the two aircraft, even at close proximity,” Lin said.

For the electromagnetic compatibility testing, the team powered up the X-59’s engine while turning on the F-15D’s radar, C-band radar transponder, and radios. Data from the X-59 were transmitted to NASA’s Mobile Operations Facility, where control room staff and engineers monitored for anomalies.

“You want to make discoveries of any potential electromagnetic interference or electromagnetic compatibility issues on the ground first,” Lin said. “This reduces risk and ensures we’re not learning about problems in the air.”

Now that electromagnetic testing is complete, the X-59 is ready to move on to aluminum bird tests – during which data will be fed to the aircraft on the ground under both normal and failure conditions – and then taxi tests before flight.

NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora

Tue, 02/25/2025 - 3:41pm
5 Min Read NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora

High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can lead to effects such as power outages. In March, NASA plans to launch its EZIE (Electrojet Zeeman Imaging Explorer) mission to learn more about these powerful currents, in the hopes of ultimately mitigating the effects of such space weather for humans on Earth.

Results from EZIE will help NASA better understand the dynamics of the Earth-Sun connection and help improve predictions of hazardous space weather that can harm astronauts, interfere with satellites, and trigger power outages.

The EZIE mission includes three CubeSats, each about the size of a carry-on suitcase. These small satellites will fly in a pearls-on-a-string formation, following each other as they orbit Earth from pole to pole about 350 miles (550 kilometers) overhead. The spacecraft will look down toward the electrojets, which flow about 60 miles (100 kilometers) above the ground in an electrified layer of Earth’s atmosphere called the ionosphere.

During every orbit, each EZIE spacecraft will map the electrojets to uncover their structure and evolution. The spacecraft will fly over the same region 2 to 10 minutes apart from one another, revealing how the electrojets change.

Previous ground-based experiments and spacecraft have observed auroral electrojets, which are a small part of a vast electric circuit that extends 100,000 miles (160,000 kilometers) from Earth to space. But for decades, scientists have debated what the overall system looks like and how it evolves. The mission team expects EZIE to resolve that debate. 

“What EZIE does is unique,” said Larry Kepko, EZIE mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “EZIE is the first mission dedicated exclusively to studying the electrojets, and it does so with a completely new measurement technique.”

This technique involves looking at microwave emission from oxygen molecules about 10 miles (16 kilometers) below the electrojets. Normally, oxygen molecules emit microwaves at a frequency of 118 Gigahertz. However, the electrojets create a magnetic field that can split apart that 118 Gigahertz emission line in a process called Zeeman splitting. The stronger the magnetic field, the farther apart the line is split.

Each of the three EZIE spacecraft will carry an instrument called the Microwave Electrojet Magnetogram to observe the Zeeman effect and measure the strength and direction of the electrojets’ magnetic fields. Built by NASA’s Jet Propulsion Laboratory (JPL) in Southern California, each of these instruments will use four antennas pointed at different angles to survey the magnetic fields along four different tracks as EZIE orbits.

The technology used in the Microwave Electrojet Magnetograms was originally developed to study Earth’s atmosphere and weather systems. Engineers at JPL had reduced the size of the radio detectors so they could fit on small satellites, including NASA’s TEMPEST-D and CubeRRT missions, and improved the components that separate light into specific wavelengths.

NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission will investigate Earth’s auroral electrojets, which flow high above Earth’s polar regions when auroras (northern and southern lights) glow. By providing unprecedented measurements of these electrical currents, EZIE will answer decades-old mysteries. Understanding these currents will also improve scientists’ capabilities for predicting hazardous space weather. NASA/Johns Hopkins APL

The electrojets flow through a region that is difficult to study directly, as it’s too high for scientific balloons to reach but too low for satellites to dwell.

“The utilization of the Zeeman technique to remotely map current-induced magnetic fields is really a game-changing approach to get these measurements at an altitude that is notoriously difficult to measure,” said Sam Yee, EZIE’s principal investigator at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.

The mission is also including citizen scientists to enhance its research, distributing dozens of EZIE-Mag magnetometer kits to students in the U.S. and volunteers around the world to compare EZIE’s observations to those from Earth. “EZIE scientists will be collecting magnetic field data from above, and the students will be collecting magnetic field data from the ground,” said Nelli Mosavi-Hoyer, EZIE project manager at APL.

The EZIE spacecraft will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California as part of the Transporter-13 rideshare mission with SpaceX via launch integrator Maverick Space Systems.

The mission will launch during what’s known as solar maximum — a phase during the 11-year solar cycle when the Sun’s activity is stronger and more frequent. This is an advantage for EZIE’s science.

“It’s better to launch during solar max,” Kepko said. “The electrojets respond directly to solar activity.”

The EZIE mission will also work alongside other NASA heliophysics missions, including PUNCH (Polarimeter to Unify the Corona and Heliosphere), launching in late February to study how material in the Sun’s outer atmosphere becomes the solar wind.

According to Yee, EZIE’s CubeSat mission not only allows scientists to address compelling questions that have not been able to answer for decades but also demonstrates that great science can be achieved cost-effectively.

“We’re leveraging the new capability of CubeSats,” Kepko added. “This is a mission that couldn’t have flown a decade ago. It’s pushing the envelope of what is possible, all on a small satellite. It’s exciting to think about what we will discover.”

The EZIE mission is funded by the Heliophysics Division within NASA’s Science Mission Directorate and is managed by the Explorers Program Office at NASA Goddard. APL leads the mission for NASA. Blue Canyon Technologies in Boulder, Colorado, built the CubeSats.

NASA’s Lucy Spacecraft Takes Its 1st Images of Asteroid Donaldjohanson

Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid  Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.

Lucy will pass within 596 miles (960 km) of the 2-mile-wide asteroid on April 20. This second asteroid encounter for the Lucy spacecraft will serve as a dress-rehearsal for the spacecraft’s main targets, the never-before-explored Jupiter Trojan asteroids. Lucy already successfully observed the tiny main belt asteroid Dinkinesh and its contact-binary moon, Selam, in November 2023. Lucy will continue to image Donaldjohanson over the next two months as part of its optical navigation program, which uses the asteroid’s apparent position against the star background to ensure an accurate flyby.

Donaldjohanson will remain an unresolved point of light during the spacecraft’s long approach and won’t start to show surface detail until the day of the encounter.

From a distance of 45 million miles (70 million km), Donaldjohanson is still dim, though it stands out clearly in this field of relatively faint stars in the constellation of Sextans. Celestial north is to the right of the frame, and the 0.11-degree field of view would correspond to 85,500 miles (140,000 km) at the distance of the asteroid. In the first of the two images, another dim asteroid can be seen photobombing in the lower right quadrant of the image. However, just as the headlights of an approaching car often appear relatively stationary, Donaldjohanson’s apparent motion between these two images is much smaller than that of this interloper, which has moved out of the field of view in the second image.

These observations were made by Lucy’s high-resolution camera, the L’LORRI instrument — short for Lucy LOng Range Reconnaissance Imager — provided by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.

Asteroid Donaldjohanson is named for anthropologist Donald Johanson, who discovered the fossilized skeleton — called “Lucy” — of a human ancestor. NASA’s Lucy mission is named for the fossil.

Lucy’s principal investigator, Hal Levison, is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the Science Mission Directorate at NASA Headquarters in Washington.
