After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, the Sombrero galaxy’s huge bulge, the tightly packed group of stars at the galaxy’s center, is illuminated, while the dust in the outer edges of the disk blocks some stellar light.
Image A: Sombrero Galaxy (NIRCam) NASA’s James Webb Space Telescope’s new image of the famous Sombrero galaxy in near-infrared wavelengths shows dust from the outer ring blocking stellar light from the inner portions of the galaxy. NASA, ESA, CSA, STScIStudying galaxies like the Sombrero at different wavelengths, including the near-infrared and mid-infrared with Webb, as well as the visible with NASA’s Hubble Space Telescope, helps astronomers understand how this complex system of stars, dust, and gas formed and evolved, along with the interplay of that material.
When compared to Hubble’s visible light image, the dust disk doesn’t look as pronounced in the new near-infrared image from Webb’s NIRCam (Near-Infrared Camera) instrument. That’s because the longer, redder wavelengths of infrared light emitted by stars slip past dust more easily, so less of that stellar light is blocked. In the mid-infrared image, we actually see that dust glow.
Image B: Sombrero Galaxy (NIRCam/MIRI) The Sombrero galaxy is split diagonally in this image: near-infrared observations from NASA’s James Webb Space Telescope are at the left, and mid-infrared observations from Webb are at the right. NASA, ESA, CSA, STScIThe Sombrero galaxy is located about 30 million light-years away from Earth at the edge of the Virgo galaxy cluster, and has a mass equal to about 800 billion Suns. This galaxy sits “edge on” to us, meaning we see it from its side.
Studies have indicated that hiding behind the galaxy’s smooth dust lane and calming glow is a turbulent past. A few oddities discovered over the years have hinted this galaxy was once part of a violent merger with at least one other galaxy.
The Sombrero is home to roughly 2,000 globular clusters, or collections of hundreds of thousands of old stars held together by gravity. Spectroscopic studies have shown the stars within these globular clusters are unexpectedly different from one another.
Stars that form around the same time from the same material should have similar chemical ‘fingerprints’ – for example, the same amounts of elements like oxygen or neon. However, this galaxy’s globular clusters show noticeable variation. A merger of different galaxies over billions of years would explain this difference.
Another piece of evidence supporting this merger theory is the warped appearance of the galaxy’s inner disk.
While our view is classified as “edge on,” we’re actually seeing this nearly edge on. Our view six degrees off the galaxy’s equator means we don’t see it directly from the side, but a little bit from above. From this view, the inner disk appears tilted inward, like the beginning of a funnel, instead of flat.

The first image shows visible light observed by the Hubble Space Telescope’s Advanced Camera for Surveys. The second is in near-infrared light and shows NASA’s Webb Space Telescope’s look at the galaxy using NIRCam (Near-Infrared Instrument). The final image shows mid-infrared light observed by Webb’s MIRI (Mid-Infrared Instrument).Credit: NASA, ESA, CSA, STScI
The powerful resolution of Webb’s NIRCam also allows us to resolve individual stars outside of, but not necessarily at the same distance as, the galaxy, some of which appear red. These are called red giants, which are cooler stars, but their large surface area causes them to glow brightly in this image. These red giants also are detected in the mid-infrared, while the smaller, bluer stars in the near-infrared “disappear” in the longer wavelengths.
Also in the NIRCam image, galaxies of diverse shapes and colors are scattered throughout the backdrop of space. The variety of their colors provides astronomers with clues about their characteristics, such as their distance from Earth.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

c-FIRST Team Sets Sights on Future Fire-observing Satellite Constellations
Two NASA-developed technologies are key components of a new high-resolution sensor for observing wildfires: High Operating Temperature Barrier Infrared Detector (HOT-BIRD), developed with support from NASA’s Earth Science Technology Office (ESTO), and a cutting-edge Digital Readout Integrated Circuit (DROIC), developed with funding from NASA’s Small Business Innovation Research (SBIR) program.
NASA’s c-FIRST instrument could provide high resolution data from a compact space-based platform in under an hour, making it easier for wildfire managers to detect and monitor active burns. Credit: NASA/JPLA novel space-based sensor for observing wildfires could allow first responders to monitor burns at a global scale, paving the way for future small satellite (SmallSat) constellations dedicated entirely to fire management and prevention.
Developed with support from NASA’s Earth Science Technology Office (ESTO), the “Compact Fire Infrared Radiance Spectral Tracker” (c-FIRST) is a small, mid-wave infrared sensor that collects thermal radiation data across five spectral bands. Most traditional space-based sensors dedicated to observing fires have long revisit times, observing a scene just once over days or even weeks. The compact c-FIRST sensor could be employed in a SmallSat constellation that could observe a scene multiple times a day, providing first responders data with high spatial resolution in under an hour.
In addition, c-FIRST’s dynamic spectral range covers the entire temperature profile of terrestrial wild fires, making it easier for first-responders to detect everything from smoldering, low-intensity fires to flaming, high intensity fires.
“Wildfires are becoming more frequent, and not only in California. It’s a worldwide problem, and it generates tons of by-products that create very unhealthy conditions for humans,” said Sarath Gunapala, who is an Engineering Fellow at NASA’s Jet Propulsion Laboratory (JPL) and serves as Principal Investigator for c-FIRST.
The need for space-based assets dedicated to wildfire management is severe. During the Palisade and Eaton Fires earlier this year, strong winds kept critical observation aircraft from taking to the skies, making it difficult for firefighters to monitor and track massive burns.
Space-based sensors with high revisit rates and high spatial resolution would give firefighters and first responders a constant source of eye-in-the-sky data.
“Ground-based assets don’t have far-away vision. They can only see a local area. And airborne assets, they can’t fly all the time. A small constellation of CubeSats could give you that constant coverage,” said Gunapala.
c-FIRST leverages decades of sensor development at JPL to achieve its compact size and high performance. In particular, the quarter-sized High Operating Temperature Barrier Infrared Detector (HOT-BIRD), a compact infrared detector also developed at JPL with ESTO support, keeps c-FIRST small, eliminating the need for bulky cryocooler subsystems that add mass to traditional infrared sensors.
With HOT-BIRD alone, c-FIRST could gather high-resolution images and quantitative retrievals of targets between 300°K (about 80°F) to 1000°K (about 1300°F). But when paired with a state-of-the-art Digital Readout Integrated Circuit (DROIC), c-FIRST can observe targets greater than 1600°K (about 2400°F).
Developed by Copious Imaging LLC. and JPL with funding from NASA’s Small Business Innovation Research (SBIR) program, this DROIC features an in-pixel digital counter to reduce saturation, allowing c-FIRST to capture reliable infrared data across a broader spectral range.
Artifical intelligence (AI) will also play a role in c-FIRST’s success. Gunapala plans to leverage AI in an onboard smart controller that parses collected data for evidence of hot spots or active burns. This data will be prioritized for downlinking, keeping first responders one step ahead of potential wildfires.
“We wanted it to be simple, small, low cost, low power, low weight, and low volume, so that it’s ideal for a small satellite constellation,” said Gunapala.
Gunapala and his team had a unique opportunity to test c-FIRST after the Palisade and Eaton Fires in California. Flying their instrument aboard NASA’s B-200 Super King Air, the scientists identified lingering hot spots in the Palisades and Eaton Canyon area five days after the initial burn had been contained.
Now, the team is eyeing a path to low Earth orbit. Gunapala explained that their current prototype employs a standard desktop computer that isn’t suited for the rigors of space, and they’re working to incorporate a radiation-tolerant computer into their instrument design.
But this successful test over Los Angeles demonstrates c-FIRST is fit for fire detection and science applications. As wildfires become increasingly common and more destructive, Gunapala hopes that this tool will help first responders combat nascent wildfires before they become catastrophes.
“To fight these things, you need to detect them when they’re very small,” said Gunapala.
A publication about c-FIRST appeared in the journal “Society of Photo-Optical Instrumentation Engineers” (SPIE) in March, 2023.

Hubble Filters a Barred Spiral This NASA/ESA Hubble Space Telescope image features the barred spiral galaxy NGC 1385. ESA/Hubble & NASA, R. Chandar, J. Lee and the PHANGS-HST teamThis NASA/ESA Hubble Space Telescope image features a luminous tangle of stars and dust called the barred spiral galaxy NGC 1385, located about 30 million light-years away. Hubble released an earlier image of NGC 1385, but the two images are notably different. This more recent image has far more pinkish-red and umber shades, whereas cool blues dominate the earlier image. This chromatic variation is not just a creative choice, but also a technical one, that represents the different number and types of filters used to collect the data that comprises the respective images.

A Star Like No Other
An unusual star (circled in white at right) behaving like no other seen before and its surroundings are featured in this composite image released on May 28, 2025. A team of astronomers combined data from NASA’s Chandra X-ray Observatory and the Square Kilometer Array Pathfinder (ASKAP) radio telescope on Wajarri Country in Australia to study the discovered object, known as ASKAP J1832−0911 (ASKAP J1832 for short).
ASKAP J1832 belongs to a class of objects called “long period radio transients” discovered in 2022 that vary in radio wave intensity in a regular way over tens of minutes. This is thousands of times longer than the length of the repeated variations seen in pulsars, which are rapidly spinning neutron stars that have repeated variations multiple times a second. ASKAP J1832 cycles in radio wave intensity every 44 minutes, placing it into this category of long period radio transients. Using Chandra, the team discovered that ASKAP J1832 is also regularly varying in X-rays every 44 minutes. This is the first time that such an X-ray signal has been found in a long period radio transient.

What’s Up: June 2025 Skywatching Tips from NASA
Venus and Saturn separate, while Mars hangs out in the evening. Plus the June solstice, and dark skies reveal our home galaxy in all of its glory.
Skywatching HighlightsAll Month – Planet Visibility:
- Venus: Rises about 2 hours before the Sun in June, and shines very brightly, low in the eastern sky, in the morning all month.
- Mars: Visible in the west for a couple of hours after sunset all month. Drops lower in the sky as June continues, and passes very close to Regulus in the constellation Leo on June 16 and 17. (They will be about half a degree apart, or the width of the full moon.)
- Jupiter: Visible quite low in the west after sunset for the first week of June, then lost in the Sun’s glare after. Will re-appear in July in the morning sky.
- Mercury: Becomes visible low in the west about 30 to 45 minutes after sunset in the last week and a half of June.
- Saturn: Rises around 3 a.m. in early June, and around 1 a.m. by the end of the month. Begins the month near Venus in the dawn sky, but rapidly pulls away, rising higher as June goes on.
Daily Highlights:
June 19 – Moon & Saturn – The third-quarter moon appears right next Saturn this morning in the hours before dawn. The pair rise in the east together around 1:30 a.m.
June 22 – Moon & Venus – Venus rises this morning next to a slender and elegant crescent moon. Look for them in the east between about 3 a.m. and sunrise.
June 20 – June Solstice – The June solstice is on June 20 for U.S. time zones (June 21 UTC). The Northern Hemisphere’s tilt toward the Sun is greatest on this day. This means the Sun travels its longest, highest arc across the sky all year for those north of the equator.
June 16 & 17 – Mars & Regulus – Mars passes quite close to the bright bluish-white star Regulus, known as the “heart” of the lion constellation, Leo. They will appear about as far apart as the width of the full moon, and should be an excellent sight in binoculars or a small telescope.
June 21-30 – Mercury becomes visible – For those with a clear view to the western horizon, Mercury becomes visible for a brief period each evening at the end of June. Look for it quite low in the sky starting 30 to 45 minutes after the Sun sets.
All month – Mars: The Red Planet can be observed for a couple of hours after dark all month. It is noticeably dimmer than it appeared in early May, as Earth speeds away in its orbit, putting greater distance between the two worlds.
All month – Milky Way core: The bright central bulge of our home galaxy, the Milky Way, is visible all night in June, continuing through August. It is best observed from dark sky locations far from bright city lights, and appears as a faint, cloud-like band arching across the sky toward the south.
TranscriptWhat’s Up for June? Mars grazes the lion’s heart, a connection to ancient times, and the galaxy in all its glory.
June Planet Observing
Starting with planet observing for this month, find Saturn and Venus in the eastern sky during the couple of hours before dawn each morning throughout the month. Saturn rapidly climbs higher in the sky each day as the month goes on. You’ll find the third quarter moon next to Saturn on the 19th, and a crescent moon next to Venus on the 22nd.
Sky chart showing Mercury with the crescent Moon following sunset in late June, 2025. NASA/JPL-CaltechMercury pops up toward the end of the month. Look for it quite low in the west, just as the glow of sunset is fading. It’s highest and most visible on the 27th.
Mars is still visible in the couple of hours after sunset toward the west, though it’s noticeably fainter than it was in early May. Over several days in mid-June, Mars passes quite close to Regulus, the bright star at the heart of the constellation Leo, the lion.

June means that Milky Way “Core Season” is here. This is the time of year when the Milky Way is visible as a faint band of hazy light arching across the sky all night. You just need to be under dark skies away from bright city lights to see it. What you’re looking at is the bright central core of our home galaxy, seen edge-on, from our position within the galaxy’s disk.
Long-exposure photos make the Milky Way’s bright stars and dark dust clouds even clearer. And while our eyes see it in visible light, NASA telescopes observe the galaxy across the spectrum — peering through dust to help us better understand our origins.
However you observe it, getting out under the Milky Way in June is a truly remarkable way to connect with the cosmos.
June Solstice
June brings the summer solstice for those north of the equator, which is the winter solstice for those south of the equator. In the Northern Hemisphere, this is when the Sun is above the horizon longer than any other day, making it the longest day of the year. The situation is reversed for the Southern Hemisphere, where it’s the shortest day of the year.
Illustration from a NASA animation showing the tilt of Earth’s axis in June (Northern Hemisphere summer) with respect to the Sun, the planet’s orbit, and the North Star, Polaris. NASA’s Goddard Space Flight CenterEarth’s tilted rotation is the culprit. The tilt is always in the same direction, with the North Pole always pointing toward Polaris, the North Star. And since that tilt stays the same, year round, when we’re on one side of the Sun in winter, the north part of the planet is tilted away from the Sun. But six months later, the planet moves halfway around its annual path, carrying us to the opposite side of Earth’s orbit, and the northern part of the planet now finds itself tilted toward the Sun. The June solstice is when this tilt is at its maximum. This is summertime for the north, bringing long days, lots more sunlight, and warmer temperatures.
The June solstice marks a precise moment in Earth’s orbit – a consistent astronomical signpost that humans have observed for millennia. Ancient structures from Stonehenge to Chichén Itzá were built, in part, to align with the solstices, demonstrating how important these celestial events were to many cultures.
So whether you’re experiencing long summer days in the northern hemisphere or the brief daylight hours of winter in the south, find a quiet spot to watch the sunset on this special day and you’ll be participating in one of humanity’s oldest astronomical traditions, connecting you to observers across thousands of years of human history.

What’s Up: June 2025 Skywatching Tips from NASA
Venus and Saturn separate, while Mars hangs out in the evening. Plus the June solstice, and dark skies reveal our home galaxy in all of its glory.
Skywatching HighlightsAll Month – Planet Visibility:
- Venus: Rises about 2 hours before the Sun in June, and shines very brightly, low in the eastern sky, in the morning all month.
- Mars: Visible in the west for a couple of hours after sunset all month. Drops lower in the sky as June continues, and passes very close to Regulus in the constellation Leo on June 16 and 17. (They will be about half a degree apart, or the width of the full moon.)
- Jupiter: Visible quite low in the west after sunset for the first week of June, then lost in the Sun’s glare after. Will re-appear in July in the morning sky.
- Mercury: Becomes visible low in the west about 30 to 45 minutes after sunset in the last week and a half of June.
- Saturn: Rises around 3 a.m. in early June, and around 1 a.m. by the end of the month. Begins the month near Venus in the dawn sky, but rapidly pulls away, rising higher as June goes on.
Daily Highlights:
June 19 – Moon & Saturn – The third-quarter moon appears right next Saturn this morning in the hours before dawn. The pair rise in the east together around 1:30 a.m.
June 22 – Moon & Venus – Venus rises this morning next to a slender and elegant crescent moon. Look for them in the east between about 3 a.m. and sunrise.
June 20 – June Solstice – The June solstice is on June 20 for U.S. time zones (June 21 UTC). The Northern Hemisphere’s tilt toward the Sun is greatest on this day. This means the Sun travels its longest, highest arc across the sky all year for those north of the equator.
June 16 & 17 – Mars & Regulus – Mars passes quite close to the bright bluish-white star Regulus, known as the “heart” of the lion constellation, Leo. They will appear about as far apart as the width of the full moon, and should be an excellent sight in binoculars or a small telescope.
June 21-30 – Mercury becomes visible – For those with a clear view to the western horizon, Mercury becomes visible for a brief period each evening at the end of June. Look for it quite low in the sky starting 30 to 45 minutes after the Sun sets.
All month – Mars: The Red Planet can be observed for a couple of hours after dark all month. It is noticeably dimmer than it appeared in early May, as Earth speeds away in its orbit, putting greater distance between the two worlds.
All month – Milky Way core: The bright central bulge of our home galaxy, the Milky Way, is visible all night in June, continuing through August. It is best observed from dark sky locations far from bright city lights, and appears as a faint, cloud-like band arching across the sky toward the south.
TranscriptWhat’s Up for June? Mars grazes the lion’s heart, a connection to ancient times, and the galaxy in all its glory.
June Planet Observing
Starting with planet observing for this month, find Saturn and Venus in the eastern sky during the couple of hours before dawn each morning throughout the month. Saturn rapidly climbs higher in the sky each day as the month goes on. You’ll find the third quarter moon next to Saturn on the 19th, and a crescent moon next to Venus on the 22nd.

Mars is still visible in the couple of hours after sunset toward the west, though it’s noticeably fainter than it was in early May. Over several days in mid-June, Mars passes quite close to Regulus, the bright star at the heart of the constellation Leo, the lion. Have a peek on the 16th and 17th with binoculars or a small telescope to see them as close as the width of the full moon.

Apocalypse When? Hubble Casts Doubt on Certainty of Galactic Collision

NASA, ESA, the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration, and B. Whitmore (STScI)
As far back as 1912, astronomers realized that the Andromeda galaxy — then thought to be only a nebula — was headed our way. A century later, astronomers using NASA’s Hubble Space Telescope were able to measure the sideways motion of Andromeda and found it was so negligible that an eventual head-on collision with the Milky Way seemed almost certain.
A smashup between our own galaxy and Andromeda would trigger a firestorm of star birth, supernovae, and maybe toss our Sun into a different orbit. Simulations had suggested it was as inevitable as, in the words of Benjamin Franklin, “death and taxes.”
But now a new study using data from Hubble and the European Space Agency’s (ESA) Gaia space telescope says “not so fast.” Researchers combining observations from the two space observatories re-examined the long-held prediction of a Milky Way – Andromeda collision, and found it is far less inevitable than astronomers had previously suspected.
“We have the most comprehensive study of this problem today that actually folds in all the observational uncertainties,” said Till Sawala, astronomer at the University of Helsinki in Finland and lead author of the study, which appears today in the journal Nature Astronomy.
His team includes researchers at Durham University, United Kingdom; the University of Toulouse, France; and the University of Western Australia. They found that there is approximately a 50-50 chance of the two galaxies colliding within the next 10 billion years. They based this conclusion on computer simulations using the latest observational data.
These galaxy images illustrate three possible encounter scenarios between our Milky Way and the neighboring Andromeda galaxy. Top left: Galaxies M81 and M82. Top right: NGC 6786, a pair of interacting galaxies. Bottom: NGC 520, two merging galaxies. Science: NASA, ESA, STScI, DSS, Till Sawala (University of Helsinki); Image Processing: Joseph DePasquale (STScI)Sawala emphasized that predicting the long-term future of galaxy interactions is highly uncertain, but the new findings challenge the previous consensus and suggest the fate of the Milky Way remains an open question.
“Even using the latest and most precise observational data available, the future of the Local Group of several dozen galaxies is uncertain. Intriguingly, we find an almost equal probability for the widely publicized merger scenario, or, conversely, an alternative one where the Milky Way and Andromeda survive unscathed,” said Sawala.
The collision of the two galaxies had seemed much more likely in 2012, when astronomers Roeland van der Marel and Tony Sohn of the Space Telescope Science Institute in Baltimore, Maryland published a detailed analysis of Hubble observations over a five-to-seven-year period, indicating a direct impact in no more than 5 billion years.
“It’s somewhat ironic that, despite the addition of more precise Hubble data taken in recent years, we are now less certain about the outcome of a potential collision. That’s because of the more complex analysis and because we consider a more complete system. But the only way to get to a new prediction about the eventual fate of the Milky Way will be with even better data,” said Sawala.
100,000 Crash-Dummy SimulationsAstronomers considered 22 different variables that could affect the potential collision between our galaxy and our neighbor, and ran 100,000 simulations called Monte Carlo simulations stretching to 10 billion years into the future.
“Because there are so many variables that each have their errors, that accumulates to rather large uncertainty about the outcome, leading to the conclusion that the chance of a direct collision is only 50% within the next 10 billion years,” said Sawala.
“The Milky Way and Andromeda alone would remain in the same plane as they orbit each other, but this doesn’t mean they need to crash. They could still go past each other,” said Sawala.
Researchers also considered the effects of the orbits of Andromeda’s large satellite galaxy, M33, and a satellite galaxy of the Milky Way called the Large Magellanic Cloud (LMC).
“The extra mass of Andromeda’s satellite galaxy M33 pulls the Milky Way a little bit more towards it. However, we also show that the LMC pulls the Milky Way off the orbital plane and away from Andromeda. It doesn’t mean that the LMC will save us from that merger, but it makes it a bit less likely,” said Sawala.
In about half of the simulations, the two main galaxies fly past each other separated by around half a million light-years or less (five times the Milky Way’s diameter). They move outward but then come back and eventually merge in the far future. The gradual decay of the orbit is caused by a process called dynamical friction between the vast dark-matter halos that surround each galaxy at the beginning.
In most of the other cases, the galaxies don’t even come close enough for dynamical friction to work effectively. In this case, the two galaxies can continue their orbital waltz for a very long time.
The new result also still leaves a small chance of around 2% for a head-on collision between the galaxies in only 4 to 5 billion years. Considering that the warming Sun makes Earth uninhabitable in roughly 1 billion years, and the Sun itself will likely burn out in 5 billion years, a collision with Andromeda is the least of our cosmic worries.
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/JPL-CaltechWritten by Abigail Fraeman, Planetary Geologist at NASA’s Jet Propulsion Laboratory
Earth planning date: Wednesday, May 28, 2025
We came in early this morning and learned that part of Tuesday’s plan didn’t execute on Mars due to a temporary issue with the arm. We collected APXS data on the target “Palo Verde Mountains,” but were not able to take the corresponding MAHLI images or drive away. So it was a straightforward decision for the planning team today to pick up where we left off yesterday, giving ourselves a second chance to collect the MAHLI observation and then complete the same 29.5-meter drive to the west (about 97 feet) that we had planned on Tuesday.
We love making lemonade from lemons when things don’t go exactly as expected in rover tactical planning, and today was no exception. Since we’re sticking around for a little bit longer, the science team decided to collect additional mosaics of impressive nearby features, including a 15×2 Mastcam mosaic of the “Mishe Mokwa” hill and an 11×2 Mastcam mosaic of fractures near “Lake Cachuma.” We’re also having another go at taking the epically long, long-distance RMI mosaic of a crater 91 kilometers away from Curiosity (almost 57 miles) that we planned yesterday, and we’re playing around with the focus settings to see if we can get a sharper image.
The team also had time for a second RMI mosaic of our very well-imaged “Texoli” butte, and a ChemCam LIBS observation on a target named “Santa Monica Bay,” which is just above the “Sisquoc River” target we observed yesterday on the bumpy rock in our workspace. As usual, we will also continue to monitor the environment around us with REMS, RAD, Navcam, and Mastcam observations.
