Curiosity Blog, Sols 4629-4630: Feeling Hollow
NASA’s Mars rover Curiosity acquired this image of its workspace, including the small crescent-shaped rock named “Wedge Tailed Hillstar,” visible in the image just above the letters “SI” written on Curiosity’s arm. Curiosity captured the image using its Left Navigation Camera on Aug. 13, 2025 — Sol 4628, or Martian day 4,628 of the Mars Science Laboratory mission — at 08:54:46 UTC.

Earth planning date: Wednesday, Aug. 13, 2025
Today’s team investigated the texture and chemistry of the bedrock within a topographic low, or hollow, found within the greater boxwork area. We will place our APXS instrument on the “Asiruqucha” target, some light-toned, small-scale nodular bedrock in the middle of our workspace. These data will help illuminate any systematic chemical trends between the hollows and ridges in this area. We always take an associated MAHLI image with every APXS measurement to help contextualize the chemistry. We will also observe a small crescent-shaped rock named “Wedge Tailed Hillstar” with MAHLI, visible in the above Navcam image just above the letters “SI” written on Curiosity’s arm.
We will use our remote sensing instruments to continue documenting the region taking stereo Mastcam images of “Cerro Paranal,” “Rio Frio,” and “Anchoveta.” The ChemCam instrument will take an image of, and collect chemical information for, the target “Camanchaca,” as well as use its Remote Micro Imager (RMI) to take high-resolution imaging of more distant boxwork features.
Once these observations are completed Curiosity will set off on a 30-meter drive (about 98 feet), taking us to an interesting ridge feature to investigate in Friday’s plan.
As usual we will continue to take our regular atmospheric monitoring observations using REMS, RAD, and DAN.

Curiosity Blog, Sols 4627-4628: A Ridge Stop in the Boxworks
NASA’s Mars rover Curiosity acquired this close-up view of the rock target “Bococo” at the intersection of several boxwork ridges, showing bright millimeter-scale nodules likely to be calcium sulfate. Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, which uses an onboard focusing process to merge multiple images of the same target, acquired at different focus positions, to bring all (or, as many as possible) features into focus in a single image. Curiosity performed the merge on Aug. 10, 2025 — Sol 4625, or Martian day 4,625 of the Mars Science Laboratory mission — at 08:00:39 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday Aug. 11, 2025

On the Curiosity team, we’re continuing our exploration of the boxwork-forming region in Gale Crater. A successful 25-meter drive (about 82 feet) brought the rover from the “peace sign” ridge intersection to a new ridge site. Several imaging investigations were pursued in today’s plan, including Mastcam observations of a potential incipient hollow (“Laguna Miniques”), and of a number of troughs to examine how fractures transition from bedrock to regolith.
With six wheels on the ground, Curiosity was also ready to deploy the rover arm for some contact science. APXS and MAHLI measurements were planned to explore the local bedrock at two points with a brushed (DRT) measurement (“Santa Catalina”) and a non-DRT measurement (“Puerto Teresa”). A third MAHLI observation will be co-targeted with one of the LIBS geochemical measurements on a light-toned block, “Palma Seca.” Because we’re in nominal sols for this plan, we were able to plan a second targeted LIBS activity to measure the composition of a high-relief feature on another block, “Yavari” before the drive.
The auto-targeted LIBS (AEGIS) that executed post-drive on sol 4626 had fallen on a bedrock target and will be documented in high resolution via Mastcam imaging.
Two long-distance imaging mosaics were planned for the ChemCam remote imager (RMI): one on a potential scarp and lens in sediments exposed on the “Mishe Mokwa” butte in the strata above the rover’s current position, and the second on an east-facing boxwork ridge with apparently exposed cross-bedding that may be related to the previously explored “Volcán Peña Blanca” ridge.
As usual, the modern Martian environment will also be observed with camera measurements of the atmospheric opacity, a Navcam movie to watch for dust lifting, and the usual REMS and DAN passive monitoring of the temperature, humidity, and neutron flux at the rover’s location.
The next drive is planned to bring us to a spot in a hollow where we hope to plan contact science on the erosionally recessive hollow bedrock in addition to imaging with a good view of the rock layers exposed in the wall of another prominent ridge.

Credit: NASA/Jef Janis This summer, NASA’s Glenn Research Center in Cleveland hosted the NASA Glenn High School Engineering Institute, a free, work-based learning experience designed to prepare rising high school juniors and seniors for careers in the aerospace workforce.
“The institute immerses students in NASA’s work, providing essential career readiness tools for future science, technology, engineering, and mathematics-focused academic and professional pursuits,” said Jerry Voltz of NASA Glenn’s Office of STEM Engagement.
Throughout the five-day sessions (offered three separate weeks in July), students used authentic NASA mission content and collaborated with Glenn’s technical experts. They gained a deeper understanding of the engineering design process, developed practical engineering solutions to real-world challenges, and tested prototypes to address key mission areas such as:
Acoustic dampening: How can we reduce noise pollution from jet engines? Power management and distribution: How can we develop a smart power system for future space stations? Simulated lunar operations: Can we invent tires that don’t use air? NASA Glenn Research Center High School Engineering Institute participants, left to right: Adriana Pudloski, Anadavel Sakthi, Aditya Rohatgi, and Alexa Apshago, make modifications to the control system program for their rover on Friday, July 18, 2025. Credit: NASA/Jef Janis Voltz said he hoped students left the program with three key takeaways: a deeper curiosity and excitement for STEM careers, firsthand insight into how cutting-edge technology developed in Cleveland contributes to NASA’s most prominent missions, and most importantly, a feeling of empowerment gained from engaging with some of NASA’s brightest minds in the field.

Curiosity Blog, Sols 4624-4626: A Busy Weekend at the Boxwork
NASA’s Mars rover Curiosity captured this image of the three intersecting ridges in front of it this weekend that make a sort of “peace sign” shape. Curiosity acquired the image using its Left Navigation Camera on Aug. 8, 2025 — Sol 4623, or Martian day 4,623 of the Mars Science Laboratory mission — at 06:20:38 UTC. NASA/JPL-Caltech Written by Alex Innanen, Atmospheric Scientist at York University
Earth planning date: Friday, Aug. 8, 2025
We continue to progress through the boxwork structures, arriving today at the “peace sign” ridges we were aiming for in our last drive. We’re spending the first two sols of the weekend at this location, learning everything we can about the boxwork ridges all around us. Then we’re driving further along and spending our third sol at our next location doing a bit more untargeted science.
Our first sol includes three contact science targets, “Palmira,” “Casicasi,” and “Bococo,” which both MAHLI and APXS will be checking out nice and close. ChemCam is also using its LIBS laser to check out Bococo, and taking a mosaic of some more distant boxwork ridges. Not to be left out, Mastcam is taking a mosaic of the intersecting peace-sign-shaped ridges, which have been given the name “Ayopaya,” as well as another mosaic of the edge of one of the nearby ridges. The environmental science group (ENV) is also taking a dust-devil movie and a surpahorizon cloud movie.
On our second sol, ChemCam has another LIBS observation of “Britania.” Mastcam has some more mosaics, today looking back at our wheel tracks to see what we might have turned up on our drive, as well as out to the more distant ridges. We also have another cloud movie coinciding with imaging from above by the CaSSIS camera on board the Trace Gas Orbiter, trying to spot the same clouds from above and below. After our drive Curiosity gets to take a nice long snooze before waking up early for our typical weekend morning ENV block, which includes three different cloud observations (it’s still the cloudy season, after all!) and two observations to look at dust in the crater and in the sky above. Later on this sol ChemCam will use AEGIS to autonomously pick a LIBS target, we’ll have a 360-degree survey to try to catch dust devils. Finally, we’re setting our sights back on the clouds, using cloud shadows on Mount Sharp to estimate cloud altitudes.
