Preparations for Next Moonwalk Simulations Underway (and Underwater)
This mosaic showing the Martian surface outside of Jezero Crater was taken by NASA’s Perseverance on Dec. 25, 2024, at the site where the rover cored a sample dubbed “Silver Mountain” from a rock likely formed during Mars’ earliest geologic period.NASA/JPL-Caltech/ASU/MSSS The diversity of rock types along the rim of Jezero Crater offers a wide glimpse of Martian history.
Scientists with NASA’s Perseverance rover are exploring what they consider a veritable Martian cornucopia full of intriguing rocky outcrops on the rim of Jezero Crater. Studying rocks, boulders, and outcrops helps scientists understand the planet’s history, evolution, and potential for past or present habitability. Since January, the rover has cored five rocks on the rim, sealing samples from three of them in sample tubes. It’s also performed up-close analysis of seven rocks and analyzed another 83 from afar by zapping them with a laser. This is the mission’s fastest science-collection tempo since the rover landed on the Red Planet more than four years ago.
Perseverance climbed the western wall of Jezero Crater for 3½ months, reaching the rim on Dec. 12, 2024, and is currently exploring a roughly 445-foot-tall (135-meter-tall) slope the science team calls “Witch Hazel Hill.” The diversity of rocks they have found there has gone beyond their expectations.
“During previous science campaigns in Jezero, it could take several months to find a rock that was significantly different from the last rock we sampled and scientifically unique enough for sampling,” said Perseverance’s project scientist, Katie Stack Morgan of NASA’s Jet Propulsion Laboratory in Southern California. “But up here on the crater rim, there are new and intriguing rocks everywhere the rover turns. It has been all we had hoped for and more.”
One of Perseverance’s hazard cameras captured the rover’s coring drill collecting the “Main River” rock sample on “Witch Hazel Hill” on March 10, 2025, the 1,441st Martian day, or sol, of the mission. NASA/JPL-Caltech That’s because Jezero Crater’s western rim contains tons of fragmented once-molten rocks that were knocked out of their subterranean home billions of years ago by one or more meteor impacts, including possibly the one that produced Jezero Crater. Perseverance is finding these formerly underground boulders juxtaposed with well-preserved layered rocks that were “born” billions of years ago on what would become the crater’s rim. And just a short drive away is a boulder showing signs that it was modified by water nestled beside one that saw little water in its past.
Oldest Sample Yet?
Perseverance collected its first crater-rim rock sample, named “Silver Mountain,” on Jan. 28. (NASA scientists informally nickname Martian features, including rocks and, separately, rock samples, to help keep track of them.) The rock it came from, called “Shallow Bay,” most likely formed at least 3.9 billion years ago during Mars’ earliest geologic period, the Noachian, and it may have been broken up and recrystallized during an ancient meteor impact.
About 360 feet (110 meters) away from that sampling site is an outcrop that caught the science team’s eye because it contains igneous minerals crystallized from magma deep in the Martian crust. (Igneous rocks can form deep underground from magma or from volcanic activity at the surface, and they are excellent record-keepers — particularly because mineral crystals within them preserve details about the precise moment they formed.) But after two coring attempts (on Feb. 4 and Feb. 8) fizzled due to the rock being so crumbly, the rover drove about 520 feet (160 meters) northwest to another scientifically intriguing rock, dubbed “Tablelands.”
Data from the rover’s instruments indicates that Tablelands is made almost entirely of serpentine minerals, which form when large amounts of water react with iron- and magnesium-bearing minerals in igneous rock. During this process, called serpentinization, the rock’s original structure and mineralogy change, often causing it to expand and fracture. Byproducts of the process sometimes include hydrogen gas, which can lead to the generation of methane in the presence of carbon dioxide. On Earth, such rocks can support microbial communities.
Coring Tablelands went smoothly. But sealing it became an engineering challenge.
Sealing the “Green Gardens” sample — collected by NASA’s Perseverance Mars rover from a rock dubbed “Tablelands” along the rim of Jezero Crater on Feb. 16, 2025 — pre-sented an engineering challenge. The sample was finally sealed on March 2.NASA/JPL-Caltech/ASU/MSSS Flick Maneuver
“This happened once before, when there was enough powdered rock at the top of the tube that it interfered with getting a perfect seal,” said Kyle Kaplan, a robotics engineer at JPL. “For Tablelands, we pulled out all the stops. Over 13 sols,” or Martian days, “we used a tool to brush out the top of the tube 33 times and made eight sealing attempts. We even flicked it a second time.”
During a flick maneuver, the sample handling arm — a little robotic arm in the rover’s belly — presses the tube against a wall inside the rover, then pulls the tube away, causing it to vibrate. On March 2, the combination of flicks and brushings cleaned the tube’s top opening enough for Perseverance to seal and store the serpentine-laden rock sample.
Eight days later, the rover had no issues sealing its third rim sample, from a rock called “Main River.” The alternating bright and dark bands on the rock were like nothing the science team had seen before.
Up Next
Following the collection of the Main River sample, the rover has continued exploring Witch Hazel Hill, analyzing three more rocky outcrops (“Sally’s Cove,” “Dennis Pond,” and “Mount Pearl”). And the team isn’t done yet.
“The last four months have been a whirlwind for the science team, and we still feel that Witch Hazel Hill has more to tell us,” said Stack. “We’ll use all the rover data gathered recently to decide if and where to collect the next sample from the crater rim. Crater rims — you gotta love ’em.”
More About Perseverance
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover is characterizing the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and is the first mission to collect and cache Martian rock and regolith.
NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program portfolio and the agency’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

Sols 4505-4506: Up, up and onto the Devil’s Gate
This image was taken by Left Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4503 (2025-04-07 00:33:50 UTC). NASA/JPL-Caltech Written by Catherine O’Connell-Cooper, Planetary Geologist at University of New Brunswick
Earth planning date: Monday, April 7, 2025
Over the weekend, we completed our drive up the steep side of a canyon, up onto “Devil’s Gate,” a small butte which forms part of the ridge along the top of the canyon and now we can see down into the next canyon. It is always true that we are going somewhere no one has been before – that’s the idea of an exploratory mission after all, and everyone kind of gets used to it, we don’t stop to think about it. But today, coming over the top of a hill like this and fully looking for the first time into an area that we have only had glimpses of before, it really brings it home that the mission is doing something extraordinary, something out of this world …. and brings that feeling of awe back into focus.
We did not pass SRAP (Slip Risk Assessment Process) a couple of times as we climbed up the side of this canyon, meaning that the contact science instruments (APXS and MAHLI) had to stand down for that day’s planning. However, this morning, in addition to a brand new vista, we saw that all six wheels are firmly on the ground and we passed SRAP quickly this morning, which must have been a relief to the rover planner in charge of assessing it today! (no one wants to be the bearer of bad news, day after day!)
Bedrock here has both flat bedrock and amazing large nodular features, which appear to have “wind tails” caused by winds consistently blowing in the same direction. This is a Touch and Go plan, so APXS and MAHLI are focusing on a single target, the brushed “Coronado” target on the flat bedrock in front of us. ChemCam will use LIBS to investigate the nodular features at “La Cumbre Peak.”
Near the rover, Mastcam will image some small diagenetic features at “Boulder Oaks” and the LIBS target. The 3×2 (2 rows of 3 images) “La Jolla Valley” mosaic focuses on a very nodular patch, just outside of the workspace reachable by the arm. Further from the rover, the 6×2 mosaic (2 rows of 6 images) “Los Penasquitos” looks at an amazing almost vertical vein. This discontinuous vein stretches for about 6 meters (about 18 feet), with vein fins sticking above the surface at various points, like a series of shark fins breaking the bedrock surface. Much further afield, ChemCam will acquire a long distance image on “Condor Peak,” which appears to have large scale vein networks, known as “boxwork structures” and may be an early example of the boxworks we are hoping to reach in Fall 2025.
The ENV (Environmental and Atmospheric group) planned a Mastcam “tau” measurement, to look at dust in the atmosphere. There is a paired Navcam activity, looking at dust devils towards the north of the crater on the first sol and towards the south on the second sol. A suprahorizon movie and our usual DAN and REMS measurements round out this plan.
Let’s see what the next drive will reveal to us!

Sols 4502-4504: Sneaking Past Devil’s Gate
NASA’s Mars rover Curiosity acquired this image of the terrain around it on April 3, 2025, showing a small ridgeline on the right side, “Devil’s Gate,” and the base of Texoli butte, visible on the left side of the image. Curiosity acquired the image using its Left Navigation Camera on Sol 4500, or Martian day 4,500 of the Mars Science Laboratory mission, at 23:08:35 UTC. NASA/JPL-Caltech Written by Michelle Minitti, Planetary Geologist at Framework
Earth planning date: Friday, April 4, 2025
We continue to make progress driving up Mount Sharp, each day gaining new perspectives on the spectacular, towering buttes surrounding our path. To get to the next canyon we can ascend, we have to swing around the north end of a small ridgeline, “Devil’s Gate,” which is on the right side of the image above.
The blocks scattered around the base of Devil’s Gate are ripe with interesting structures, which motivated the acquisition of an RMI mosaic across the ridge. Those blocks are also inconvenient for driving and parking the rover with all six wheels firmly on the ground, the latter of which is needed to be able to unstow the arm for APXS and MAHLI observations. Our last drive ended with our front wheels not quite on solid ground, so we had to forego arm work this weekend. But as you can imagine with the view around us, Devil’s Gate was not the only feature that the team was excited to image. ChemCam added a second RMI mosaic along the base of “Texoli” butte, which you can see the flank of on the left side of the image above. Mastcam planned a mosaic across an expanse of bedrock that looks like rolling waves frozen in place at “Maidenhair Falls.”
The rocks right in front of the rover were also wonderfully complex in their textures and structures. ChemCam targeted two different textures expressed in the workspace — one across fine layers at “Arroyo Burro” and one across rough, platy, and gray material at “Arroyo Conejo.” Mastcam documented the block containing both these targets with a stereo mosaic that will give us a three-dimensional view of its structures.
We planned a drive to get us further around the base of Devil’s Gate, after which we will acquire an autonomously-targeted ChemCam LIBS raster and early morning Navcam and Mastcam mosaics looking back on the path we have recently traveled. DAN is scheduled for about seven hours of data collecting across the plan, both during science blocks and our drive. The sky gets a lot of attention in this plan with suites of observations taken at two different times — near midday and early morning — to assess variability across the day. Each window of time had Navcam dust-devil and cloud movies, and measurements of the amount of dust in the atmosphere. The early morning block of observations also had multiple cloud movies cover the full sky. REMS and RAD have regular measurements across the sols.
See you Monday, when we are a bit farther past Devil’s Gate!

Sols 4500-4501: Bedrock With a Side of Sand
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on March 28, 2025 — Sol 4494, or Martian day 4,494 of the Mars Science Laboratory mission — at 17:06:34 UTC. NASA/JPL-Caltech Written by Sharon Wilson Purdy, Planetary Geologist at Smithsonian National Air and Space Museum
Earth planning date: Wednesday, April 2, 2025
Wow, sol 4500. What an impressive number of sols (Martian days) exploring the Red Planet! This delightfully even sol number made me wonder where the Mars Exploration Rover (MER) Opportunity was at this point in her mission (Opportunity’s twin rover, Spirit, explored Gusev crater on Mars for roughly 2210 sols). As it turns out, Opportunity was driving over fairly smooth terrain on sol 4500 and was approaching a light-toned rounded hill named “Spirit Mound” on the western rim of Endeavour crater in Meridiani Planum.
I am always so impressed and proud when I stop to think about the incredible fleet of rovers we have safely landed and operated on Mars, and the amazing scientific discoveries that have resulted from these missions!
Today I served on science operations as the “keeper of the plan” for the geology and mineralogy theme group. In this role, I assembled the activities in our team planning software for this two-sol plan. Our small plan becomes part of a much larger set of instructions that will be relayed up to the rover later today. Currently, the Curiosity rover is driving up Mount Sharp over broken-up blocks of bedrock and sand through a small canyon en route to the boxwork structures ahead. This bumpy terrain can sometimes make it hard to pass the “Slip Risk Assessment Process” (SRAP) where all six wheels are required to be stable on the ground before we can unstow our robotic arm to use the contact science instruments. After our successful 8-meter drive (about 26 feet) from yestersol we passed SRAP and got to work selecting targets for contact and remote observations.
The team chose to characterize a bedrock target in front of us called “Chuckwalla” using the dust removal tool (DRT), APXS, and MAHLI. ChemCam used its LIBS instrument to analyze the chemistry of a nearby bedrock target with a knobby texture, “Pechacho,” and took a long distance RMI image to study the interesting layering in the “Devil’s Gate” butte. Mastcam assembled an impressive portfolio of observations in this two-sol plan. The team imaged variations in bedrock textures at “Jalama” and “Julian” and documented the nature of the “Mishe Mokwa” ridgeline. In addition, Mastcam imaged darker rocks within a previously acquired mosaic of Devil’s Gate and investigated narrow troughs (small depressions) within the sand in the workspace.
The environmental theme group, with their eye on the sky, included activities to measure the optical depth of the atmosphere, constrain aerosol scattering properties, and observe clouds. A very busy day of planning for sols 4500-4501, with many more to come!

Sols 4498-4499: Flexing Our Arm Once Again
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on March 30, 2025 — Sol 4496, or Martian day 4,496 of the Mars Science Laboratory mission — at 20:12:48 UTC. NASA/JPL-Caltech Written by Conor Hayes, Graduate Student at York University
Earth planning date: Monday, March 31, 2025
Planning today began with two pieces of great news. First, our 50-meter drive (about 164 feet) from the weekend plan completed successfully, bringing us oh-so-close to finally driving out of the small canyon that we’ve been traversing through and toward the “boxwork” structures to our southwest. Second, we passed our “Slip Risk Assessment Process” (SRAP), confirming that all six of Curiosity’s wheels are parked firmly on solid ground. Avid readers of this blog will be familiar with last week’s SRAP challenges, which prevented us from using the rover’s arm for the entire week. With a green light on SRAP, we were finally able to put our suite of contact science instruments back to work today.
The arm gets to work early on the first sol of this plan, with an APXS integration on “Los Osos,” a bedrock target in our workspace, after it has been cleared of the ubiquitous Martian dust by DRT. The rest of our arm activities consist of a series of MAHLI observations later in the afternoon, both of Los Osos and “Black Star Canyon.”
Of course, just because we managed to get contact science in this plan doesn’t mean we’re letting our remote sensing instruments take a break. In fact, we have more than two hours of remote sensing, split between the two sols and the two science teams (Geology and Mineralogy [GEO] and Atmosphere and Environment [ENV]). GEO will be using Mastcam to survey both the highs and the lows of the terrain, with mosaics of “Devil’s Gate” (some stratigraphy in a nearby ledge) and some small troughs close to the rover. We’ll also be getting even more Mastcam images of “Gould Mesa,” an imaging target in many previous plans, as we continue to drive past it. ChemCam gets involved with a LIBS observation of “Fishbowls,” which will also be imaged by Mastcam, a post-drive AEGIS, and two RMI mosaics of Gould Mesa and “Torote Bowl,” which was also imaged over the weekend.
ENV’s activities are fairly typical for this time of year as Curiosity monitors the development of the Aphelion Cloud Belt (ACB) with several Navcam cloud movies, as well as seasonal changes in the amount of dust in and above Gale with Navcam line-of-sight observations and Mastcam taus. We’ll also be taking a Navcam dust devil movie to see if we can catch any cold-weather wind-driven dust movement. ENV also filled this plan with their usual set of REMS, RAD, and DAN observations.
The drive planned today is significantly shorter than the one over the weekend, at just about 10 meters (about 33 feet). This is because we’re driving up a small ridge, which limits our ability to see what’s on the other side. Although our rover knows how to keep itself safe, we still prefer not to drive through terrain that we can’t see in advance, if it can be avoided. Once we’ve got a better eye on what lies in front of us, we will hopefully be able to continue our speedy trek toward the boxwork structures.
