Red Rocks with Green Spots at ‘Serpentine Rapids’
NASA’s Mars Perseverance rover acquired this image, a nighttime mosaic of the Malgosa Crest abrasion patch at “Serpentine Rapids,” using its SHERLOC WATSON camera, located on the turret at the end of the rover’s robotic arm. The diameter of the abrasion patch is 5 centimeters (about 2 inches) and the large green spot in the upper center left of the image is approximately 2 millimeters (about 0.08 inch) in diameter. Mosaic source images have been debayered, flat-fielded, and linearly color stretched. This image was acquired on Aug. 19, 2024 (sol 1243, or Martian day 1,243 of the Mars 2020 mission) at the local mean solar time of 19:45:30. NASA/JPL-Caltech After discovering and sampling the “leopard spots” of “Bright Angel,” it became apparent that Perseverance’s journey of discovery in this region was not yet finished. Approximately 20 sols (Martian days) after driving south across Neretva Vallis from Bright Angel, the rover discovered the enigmatic and unique red rocks of “Serpentine Rapids.”
At Serpentine Rapids, Perseverance used its abrading bit to create an abrasion patch in a red rock outcrop named “Wallace Butte.” The 5-cm diameter abrasion patch revealed a striking array of white, black, and green colors within the rock. One of the biggest surprises for the rover team was the presence of the drab-green-colored spots within the abrasion patch, which are composed of dark-toned cores with fuzzy, light green rims.
On Earth, red rocks — sometimes called “red beds” — generally get their color from oxidized iron (Fe3+), which is the same form of iron that makes our blood red, or the rusty red color of metal left outside. Green spots like those observed in the Wallace Butte abrasion are common in ancient “red beds” on Earth and form when liquid water percolates through the sediment before it hardens to rock, kicking off a chemical reaction that transforms oxidized iron to its reduced (Fe2+) form, resulting in a greenish hue. On Earth, microbes are sometimes involved in this iron reduction reaction. However, green spots can also result from decaying organic matter that creates localized reducing conditions. Interactions between sulfur and iron can also create iron-reducing conditions without the involvement of microbial life.
Unfortunately, there was not enough room to safely place the rover arm containing the SHERLOC and PIXL instruments directly atop one of the green spots within the abrasion patch, so their composition remains a mystery. However, the team is always on the lookout for similar interesting and unexpected features in the rocks.
The science and engineering teams are now dealing with incredibly steep terrain as Perseverance ascends the Jezero Crater rim. In the meantime, the Science Team is hanging on to the edge of their seats with excitement and wonder as Perseverance makes the steep climb out of the crater it has called home for the past two years. There is no shortage of wonder and excitement across the team as we contemplate what secrets the ancient rocks of the Jezero Crater rim may hold.

Sols 4307-4308: Bright Rocks Catch Our Eyes
NASA’s Mars rover Curiosity captured this image while exploring a rock-strewn channel of Gediz Vallis on the Red Planet. Mission scientists were particularly intrigued to investigate several bright-toned rocks (at the middle-right, bottom-right and bottom-center of the image), similar to rocks that Curiosity had encountered previously that were unexpectedly rich in sulfur. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4306 — Martian day 4,306 of the Mars Science Laboratory Mission — on Sept. 16, 2024 at 12:47:18 UTC. NASA/JPL-Caltech Earth planning date: Monday, Sept. 16, 2024
We made good progress through Gediz Vallis in the weekend drive, landing in a segment of the channel containing a mix of loose rubble and other channel-filling debris. Amongst the jumbled scene, though, particular objects of interest caught our eye: bright rocks. In past workspaces in Gediz Vallis, similar bright rocks have been associated with very high to almost pure sulfur contents. As all good geologists know, however, color is not diagnostic, so we cannot assume these are the same as sulfur-rich rocks we have encountered previously. The only way to know is to collect data, and that was a significant focus of today’s plan.
We planned multiple mosaics across the examples of bright rocks visible in the image above. Mastcam and ChemCam RMI will cover “Bright Dot Lake” and “Sheep Creek” both in the right midfield of the image. Mastcam imaged the example in the bottom right corner of the image at “Marble Falls,” and ChemCam LIBS targeted one of the small bright fragments along the bottom of the image at “Blanc Lake.” There was also a small bit of bright material in the workspace, but unfortunately, it was not reachable by APXS. APXS analyzed a spot near the bright material, at target “Frog Lake,” and MAHLI was able to tack on a few extra images around that target that should capture the bright material. MAHLI also imaged a vuggy target in the workspace at “Grasshopper Flat.” The wider context of the channel was also of interest for imaging, so we captured the full expanse of the channel with one Mastcam mosaic, and focused another on mounds distributed through the channel at target “Copper Creek.”
Even with all this rock imaging, we did not miss a beat with our environmental monitoring. We planned regular RAD, REMS, and DAN measurements, mid and late day atmospheric dust observations, a cloud movie, and dust devil imaging.
Our drive is planned to take us up onto one of the ridges in the channel. Will we find more bright rocks there? Or something new and unexpected that was delivered down Gediz Vallis by some past Martian flood or debris flow? Only the channel knows!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A Terrier Improved Malemute sounding rocket carrying RockSat-X student developed experiments being raised on the launch rail on Wallops IslandNASA NASA’s Wallops Flight Facility in Virginia is scheduled to launch a sounding rocket carrying student-developed experiments for the RockSat-X mission on Tuesday, Aug. 13.
The Terrier-Improved Malemute rocket is expected to reach an altitude of about 100 miles (162 kilometers) before descending by parachute into the Atlantic Ocean to be recovered. The launch window for the mission is 6 a.m. to 9 a.m. EDT, Aug. 13, with backup days of Aug. 14, 15, and 16. The Wallops Visitor Center’s launch viewing area will open at 5 a.m. for launch viewing. A livestream of the mission will begin 15 minutes before launch on the Wallops YouTube channel. Launch updates are also available via the Wallops Facebook page. The launch may be visible in the Chesapeake Bay region.
The rocket will carry experiments developed by nine university and community college teams as part of NASA’s RockSat programs.
“The RockSat program provides unique hands-on experiences for students in the development of scientific experiments and working in teams, so these students are ready to enter STEM careers,” said Dr. Joyce Winterton, Wallops senior advisor for education and leadership development.

The University of Alabama Huntsville is flying two primary experiments: Joint Union of Payload Information and Technology between Experiments and Rockets (JUPITER), a custom spacecraft bus-like system that connects experiment hardware with existing launch vehicle electronics. SwingSat will increase the technology readiness level of momentum exchange tether technology in the context of satellite constellation deployments. The University of Alberta will demonstrate instruments for characterizing plasma wave activity and electron microburst precipitation, specifically by resolving precipitating relativistic and sub-relativistic electrons. The project will be capable of measuring magnetic plasma wave oscillations, including chorus waves and ground-based Very Low Frequency transmitters. The outcome of this mission will improve the Technology Readiness Level. Clemson University’s experiment will measure electron density and temperature of the E region ionosphere, between 56- 93 miles (90-150 kilometers). The College of the Canyons experiment will deploy three capsules to gather data on greenhouse gases in the upper atmosphere to aid in the fight against climate change. The Community Colleges of Colorado, a collaboration of Arapahoe and Red Rocks Community Colleges, aims to evaluate how microgravity affects the mechanical properties of lunar regolith simulants sintered during suborbital flight. The mission will also create a cost-efficient star tracker using off-the-shelf materials and open-source software. Northwest Nazarene University is testing a space-rated robotic arm capable of tracking and capturing objects. The arm will deploy and catch three balls, then stow itself for reentry, and will also capture video footage of all the catch attempts. The University of Puerto Rico will collect environmental data of the atmosphere using humidity, temperature, and pressure sensors. Using an Ultra High Frequency antenna, telecommunications will use open-source protocols to beam down data to ground stations at Wallops. Uninterrupted Virtual Reality footage of flight will be used for STEM engagement. Virginia Tech’s experiment tests a space tether that provides a small CubeSat with power and a mechanical connection. West Virginia Space Collaboration, a collaboration of five West Virginia universities, will conduct nine independent experiments flying on the 2024 RockSat-X mission. Included are: Lower Ionosphere Electric Field Double Probes (LIEF), which will study plasma and electric field densities throughout the flight. A mycelium properties experiment that will study the mechanical properties of mycelium under space flight conditions. A flight dynamics module that will record data on rocket and space flight conditions. A Geiger counter to detect radiation density during flight. A heat study that will analyze heat dissipation during space flight and reentry. A study on the effect of spaceflight on microbes in soil during flight and reentry.

Sols 4250-4252: So Many Rocks, So Little Time
This image was taken by Right Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4248 – Martian day 4,248 of the Mars Science Laboratory mission – on July 19, 2024, at 02:34:33 UTC. Earth planning date: Friday, July 19, 2024
As usual with our weekend plans, we are packing a lot of science into today’s three-sol plan. I had the fun of planning a complex and large set of arm activities as the Arm Rover Planner today. Since we did not drive in Wednesday’s plan, we still are looking at targets in the same workspace – shown in the image with the arm down on a contact science target. We are finishing up the observations at our current location on “Fairview Dome.”
In our first set of imaging, we begin with a Navcam dust devil movie. Then, ChemCam is taking a LIBS observation on “Koip Peak” (a nodular bedrock) and an RMI mosaic on Texoli butte. We also have Mastcam imaging on Koip Peak, “Amphitheater Dome” (Wednesday’s contact science target), the channel wall, and the AEGIS target from sol 4247. After a nap, we’re ready for the arm. The arm work was challenging today, as we had a lot to do. We start by taking MAHLI images of a target named “Saddlebag Lake,” a bumpy, rough part of the bedrock. We then brush and take MAHLI images of “Eagle Scout Peak,” which is a dusty portion of the same bedrock. We are also running an experiment today to see if we can run the DRT brush in parallel with using our UHF antenna, to downlink data without impacting the data. After integrating with APXS on Eagle Scout Peak, we take nighttime MALHI imaging (using the LEDs) of the CheMin inlet to look for any signs of stuck sample and stow the arm. We are also cleaning out the sample from the CheMin instrument, by “dumping” it out and then running an analysis on the empty cell.
The second sol begins with more atmospheric observations. We have another ChemCam LIBS observation of the “Smith Peak” target, which is a dark and dusty spot on the bedrock, and Mastcam mosaics of “Virginia Peak” (the gray edge of the rock), the summit of “Milestone Peak”, and “McDonald Pass” (a nearby piece of bedrock that looks similar to our recent drill target, “Whitebark Pass”). We’re then ready to drive. Today’s drive is taking us about 30 meters south (about 98 feet). We’re driving cross-slope, which is always a challenge because we have to account for sliding sideways, away from the planned path. Fortunately there are no major hazards in the area, so we can tolerate some deviation from our path. This drive should take us close to our next potential drill location! We’re also testing, for the first time on Mars, a new capability that helps the rover make more precise arc turns, which can reduce the amount of steering we need to do, and help preserve our wheels. After taking our normal post-drive imaging, our final activity on this sol is an APXS atmospheric observation.
On our third sol, around noon, we are taking a ChemCam AEGIS observation and a lot of atmospheric observations, including another dust devil survey and Mastcam solar tau. Finally, just before handing things over to Monday’s plan, we take additional atmospheric observations in the early morning.

Bright Rocks and “Bright Angel”
NASA’s Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. This image was acquired on May 29, 2024 (Sol 1164) at the local mean solar time of 12:40:40.
NASA/JPL-Caltech/ASU Last week the Perseverance rover descended into Neretva Vallis, an ancient river channel that brought water into Jezero Crater billions of years ago. Rocks found in Neretva Vallis could have come from far upstream, giving us the opportunity to examine material which may have come from many kilometers away. Turning north into the channel has allowed us to complete longer drives, a refreshing change of pace from the rugged terrain we tackled in the Western Margin.
Dodging dunes at Dunraven Pass, we approached Mount Washburn, an outcrop which our Mastcam-Z camera identified from a distance as having spectrally diverse boulders and patches of lighter-toned bedrock. Upon arriving, we were amazed by the variety of colors and textures in the rocks around the rover and immediately got to work planning observations with our remote sensing instruments. Much of our focus was on “Atoko Point”, a bright boulder with dark speckles. After acquiring numerous Mastcam-Z multispectral images and zapping Atoko Point with our SuperCam laser, we began to look towards our next goal: “Bright Angel”. This exposure of light-toned rock, northwest of our current location, stands out vividly in orbital imagery. By examining outcrops at Bright Angel and assessing stratigraphic relationships (i.e. the vertical sequence and stacking of different sets of rocks), it is hoped that we can understand its connection to Neretva Vallis and the crater rim.
Intrigued by what we have found at Mount Washburn, our first stop in the channel, we have now turned to the terrain to the north, where we will add yet another chapter to Perseverance’s story at “Bright Angel”.
