Curiosity Blog, Sols 4641-4648: Thinking Outside and Inside the ‘Boxwork’
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on Aug. 28, 2025 — Sol 4643, or Martian day 4,643 of the Mars Science Laboratory mission — at 20:45:52 UTC.

Earth planning week: Aug. 25, 2025.
This week Curiosity has been exploring the boxwork unit, investigating both the ridges and the hollows to better characterize them and understand how they may have formed. We’ve been doing lots of remote science, contact science, and driving in each plan. In addition, we have our standard daily environmental observations to look at dust in the atmosphere. We can still see distant targets like the crater rim, but temperatures will soon begin to warm up as we start moving into a dustier part of the year. And after each drive, we also use AEGIS to do some autonomous target selection for ChemCam observations. I was the arm rover planner for the 4645-4648 plan on Friday.
For Monday’s plan (sols 4641-4642), after a successful weekend drive Curiosity began on the edge of a boxwork ridge. We did a lot of imaging, including Mastcam mosaics of “El Alto,” an upturned rock near a wheel, the ridge forming the south side of the Mojo hollow, “Sauces,” our contact science target, and “Navidad,” an extension of our current workspace. We also took ChemCam LIBS of Sauces and an RMI mosaic. The rover planners did not find any bedrock large enough to brush, but did MAHLI and APXS on Sauces. Ready to drive, Curiosity drove about 15 meters (about 49 feet) around the ridge to the south and into the next hollow, named “Mojo.”
In Wednesday’s plan (sols 4643-4644), Curiosity was successfully parked in the Mojo hollow. We started with a lot of imaging, including Mastcam mosaics of the ridges around the Mojo hollow, a nearby trough and the hollow floor to look for regolith movement. We also imaged a fractured float rock named “La Laguna Verde.” ChemCam planned a LIBS target on “Corani,” a thin resistant clast sticking out of the regolith, a RMI mosaic of a target on the north ridge named “Cocotoni,” and a long-distance RMI mosaic of “Babati Mons,” a mound about 100 kilometers (about 62 miles) away that we can see peeking over the rim of Gale crater! With no bedrock in the workspace, the rover planners did MAHLI and APXS observations on a regolith target named “Tarapacá.” The 12-meter drive in this plan (about 39 feet) was challenging; driving out of the hollow and up onto the ridge required the rover to overcome tilts above 20 degrees, where the rover can experience a lot of slip. Also, with the drive late in the day, it was challenging to determine where Curiosity should be looking to track her slip using Visual Odometry without getting blinded by the sun or losing features in shadows. Making sure VO works well is particularly important on drives like this when we expect a lot of slip.
Friday’s plan, like most weekend plans, was more complex — particularly because this four-sol plan also covers the Labor Day holiday on Monday. Fortunately, the Wednesday drive was successful, and we reached the desired parking location on the ridge south of Mojo for imaging and contact science. The included image looks back over the rover’s shoulder, where we can see the ridge and hollow. We took a lot of imaging looking at hollows and the associated ridges. We are taking a Mastcam mosaic of “Jorginho Cove,” a target covering the ridge we are parked on and the next hollow to the south, “Pica,” a float rock that is grayish in color, and a ridge/hollow pair named “Laguna Colorada.” We also take ChemCam LIBS observations of Pica and two light-toned pieces of bedrock named “Tin Tin” and ”Olca.” ChemCam takes RMI observations of “Briones,” which is a channel on the crater rim, “La Serena,” some linear features in the crater wall, and a channel that feeds into the Peace Vallis fan.
After a week of fairly simple arm targets, the rover planners had a real challenge with this workspace. The rocks were mostly too small and too rough to brush, but we did find one spot after a lot of looking. We did DRT, APXS, and MAHLI on this spot, named “San Jose,” and also did MAHLI and APXS on another rock named “Malla Qullu.” This last drive of the week is about 15 meters (about 49 feet) following along a ridge and then driving onto a nearby one.

Patricia White is a contracting officer at NASA’s Stennis Space Center, where she contributes to NASA’s Artemis program that will send astronauts to the Moon to prepare for future human exploration of Mars. NASA/Danny Nowlin When NASA’s Artemis II mission launches in 2026, it will inspire the world through discovery in a new Golden Age of innovation and exploration.
It will be another inspiring NASA moment Patricia White can add to her growing list.
White supports the Artemis program to send astronauts to the Moon to prepare for future human exploration of Mars as a contracting officer at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
White takes special pride in the test operations contract she helped draft. The contract provides support to the Fred Haise Test Stand, which tests the RS-25 engines that will help power NASA’s SLS (Space Launch System) rocket on Artemis missions.
“I was awestruck the first time I witnessed an engine test,” White said. “I remember how small I felt in comparison to this big and fascinating world, and I wondered what that engine would see that I would never be able to see.”
Four RS-25 engines tested at NASA Stennis will help launch Artemis II with four astronauts to venture around the Moon. As the first crewed Artemis mission, it will represent another milestone for the nation’s human space exploration effort.
From Interstate Signs to NASA Career
White describes NASA Stennis as a hidden gem. Growing up in nearby Slidell, Louisiana, she had driven by the interstate signs pointing toward NASA Stennis her entire life.
When she heard about a job opportunity at the center, she immediately applied. Initially hired as a contractor with only a high school diploma in February 2008, White found her motivation among NASA’s ranks.
“I work with very inspiring people, and it only took one person to say, ‘You should go to college’ to give me the courage to go so late in life,” she said.
Hard But Worth It
White began college classes in her 40s and finished at 50. She balanced a marriage, full-time job, academic studies, and household responsibilities. When she started her educational journey, her children were either toddlers or newborns. They were growing up as she stayed in school for nine years while meeting life’s challenges.
“It was hard, but it was so worth it,” she said. “I love my job and what I do, and even though it is crazy busy, I look forward to working at NASA every single day.”
She joined NASA officially in 2013, going from contractor to civil servant.
Setting an Example
White’s proudest work moment came when she brought home the NASA Early Career Achievement award and medal. It served as a tangible symbol of her success she could share with her family.
“It was a long road from being hired as an intern, and we all made extraordinary sacrifices,” she said. “I wanted to share it with them and set a good example for my children.”
As Artemis II prepares to carry humans back to lunar orbit for the first time in over 50 years, White takes pride knowing her work helps power humanity’s return to deep space exploration. Her work is proof that sometimes the most important journeys begin right in one’s own backyard.

Curiosity Blog, Sols 4638-4640: Imaging Extravaganza Atop a Ridge
NASA’s Mars rover Curiosity acquired this image on Aug. 21, 2025, looking across the ridge that the rover is currently parked near the edge of, looking down into the “Thumb” region that mission planners hope to be exploring next week. Curiosity captured this image using its Left Navigation Camera on Sol 4636, or Martian day 4,636 of the MArs Science Laboratory mission, at 16:09:13 UTC.

Earth planning date: Friday, Aug. 22, 2025
Curiosity is continuing its winding path through the mysterious boxwork structures that have been a major focus of the last several months of the mission. After driving away from “Río Frío,” we are now parked on top of a ridge overlooking a topographic depression that we’ve nicknamed the “Thumb.” The image on this post shows that ridge running along the “thumb’s” edge. Our goal today is to characterize this ridge before we drive down into the Thumb.
Because we had a lot of power and three sols available to play around with, this weekend plan is packed with a lot of good science. The boxwork structures in our immediate vicinity get a lot of attention, with Mastcam images planned of the targets “Wallatiri,” “Wallatiri 2,” “Mojo,” “Samaipata,” “Fort Samaipata,” and “Río Lluta,” as well as a nearby trough. ChemCam will be taking LIBS measurements of both Samaipata and Fort Saaipata as well. Samaipata gets even more attention from MAHLI, in addition to the targets “Vitichi” and “Tartagalita,” both of which will also be observed by APXS.
The boxwork structures don’t get all of the fun today, though. In addition to all of the boxwork observations, Mastcam will be documenting the ChemCam AEGIS target from Monday’s plan, and will also be doing some more imaging of the “Mishe Mokwa” butte. The highlight of Mastcam’s work in this plan (at least in my opinion) is the large 44-image mosaic of the north crater rim, taking advantage of the particularly low dust content of the atmosphere at this time of year. ChemCam will be taking several RMI images of Mishe Mokwa and a distant outcrop at “Dragones” that we will be driving towards over the next several months, as well as the usual post-drive AEGIS.
Rounding out this plan is a collection of observations of the atmosphere. In addition to typical DAN, REMS, and RAD activities, Curiosity’s Navcams will be put to work with a dust-devil movie, dust-devil survey, five cloud movies, and two line-of-sight observations of the north crater rim. Mastcam also gets involved in the environmental fun with a tau to track the amount of dust in the air.
Even with all of these activities, we decided that we aren’t yet done with this area. The drive in today’s plan is a short bump of about 2 meters (about 6.6 feet), so we’re all looking forward to continuing our investigation of this ridge on Monday.

Curiosity Blog, Sols 4636-4637: Up Against a Wall
NASA’s Mars rover Curiosity acquired this image, showing itself parked at the wall of a fracture named “Río Frío.” Curiosity used its Left Navigation Camera on Aug. 19, 2025 — Sol 4634, or Martian day 4,634 of the Mars Science Laboratory mission — at 14:51:33 UTC. NASA/JPL-Caltech Written by Michelle Minitti, MAHLI Deputy Principal Investigator, Framework
Earth planning date: Wednesday, Aug. 20, 2025
What does a good rover do when her back is up against a wall? Fight for science!
Curiosity indeed fought the good fight at “Río Frío,” the wall of one of the many ridges cutting through the boxwork terrain we have been systematically exploring. The observations along the wall today provide insight into the internal structure and chemistry of the ridges, hopefully giving us clues as to why they are standing proud relative to the surrounding terrain.
The structural story will be told by the large Mastcam mosaics we planned, covering the ridge from base to top, and from a MAHLI mosaic covering a horizon of the wall filled with resistant nodules and smooth, swooping surfaces cutting in all directions that are likely veins. The mosaic target, “Jardín de las Delicias,” will surely yield a surfeit of Martian delights. The chemical story will be told by APXS analysis of the nodule-filled target “Minimini” and SuperCam analysis of a vein at “El Tapado.” In contrast to the ridge itself, we planned a Mastcam mosaic of part of the hollow at the base of the ridge at target “Playa Zapatilla.”
Beyond the ridge, we planned Mastcam and ChemCam imaging of the “Paniri” and “Mishe Mokwa” buttes, respectively, and sky observations with Navcam and Mastcam. DAN, RAD, and REMS run periodically through the plan keeping their eye on the Martian environment. Our drive will take us to a smaller ridge perpendicular to Río Frío, where we will once again fight to learn the secrets these ridges have to tell about Mars’ past.
