Sols 4316-4317: Hunting for Sulfur
This image was taken by the Left Navigation Camera (NavCam) aboard NASA’s Mars rover Curiosity, and captures the bright stones of the “Sheep Creek” target — just above the rover wheel – which strongly resemble elemental sulfur blocks identified earlier in the traverse. This image was taken on sol 4314, Martian day 4,314 of the Mars Science Laboratory mission, on Sept. 24, 2024, at 20:24:50 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Sept. 25, 2024
Navigating the rugged, unforgiving Martian terrain is always a challenge, and our recent attempt to reach the “Sheep Creek” target highlights this. We had aimed for small, distant bright rocks, but from 50 meters away (about 164 feet), the limited resolution of our images made it difficult to fine-tune navigation. After an ambitious drive, the rover came agonizingly close — stopping just short of these small bright rocks. The rocks, with their distinctive rounded and pitted “weathering” pattern (pictured), strongly resemble elemental sulfur blocks that we’ve encountered before. Frustratingly, although the target rocks were right under the front wheel and clearly visible in our navigation cameras, they remained just out of reach of the rover’s arm.
While the rover’s arm couldn’t quite reach the bright stones of Sheep Creek, we didn’t let that stop us and planned to use other onboard instruments to help us analyze the composition, textures, and context before we move to our next position. As the Keeper of the Plan for the Geology and Mineralogy theme group, my role was to ensure all those activities were recorded in the plan.
To find out the composition of the stones of Sheep Creek, we used ChemCam (our onboard laser) to observe two promising stones we’ve named “Arch Rock” and “Ash Mountain.” We’re hoping to see if they have any evidence of elemental sulfur as their appearance suggests. For a closer look at the texture, we will take high-resolution, color images with Mastcam (which you can also view in 3D with red and blue anaglyph glasses!). We also want to look at an interesting transition between light-colored and dark-colored bedrock nearby, which we will cover with more high-resolution, colored images. This transition could give us clues about where the unusual white rocks of Sheep Creek came from and how they formed.
We had our eye on another bright rock in the area, named “Beryl Lake.” It had an interesting bright-toned crusty appearance and as we could reach it with the rover arm, we used our APXS tool (think of it as a chemical scanner) to see its composition and if it had any traces of sulfur. We took a closer look with our rover hand lens (MAHLI) at a rock called “Aster Lake,” which had intriguing white patches that might be similar to the stones of Sheep Creek. Ultimately, our science goal this plan was to collect data on whether these bright-toned stones had evidence of elemental sulfur and increase our understanding on how they formed.
Next, we’ll carefully reposition the rover to move closer to these interesting targets — a maneuver that we call a “bump” — so that next plan, set to occur over the weekend, we’ll be able to get up close and personal with the white stones of Sheep Creek. While the rover waits for the weekend plan, we’re setting up the rover to do some “untargeted” science after the drive. This includes using an automated tool called AEGIS that finds interesting targets on its own and zaps them with the ChemCam laser. Plus, it’s a good time to record some observations of the modern Martian environment, so we’ll make the most of the time to measure dust levels, take movies that will hopefully capture some dust devils, and look at clouds — if any — in the Martian sky.
We’re looking forward to the weekend plan to hopefully get another chance to do some contact science on targets that may be rich in sulfur!

NASA/Joel Kowsky NASA launched its reimagined art program by unveiling two murals on Sept. 23, 2024. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. The vision of this next phase is to inspire and engage the Artemis Generation with community murals and other art projects for the benefit of humanity.
NASA has long used art to tell the story of its awe-inspiring missions. Soon after its inception, the agency started a formal program commissioning artists to develop inspiring pieces like portraits and paintings that highlighted an unexpected side of the agency. In 1962, NASA’s then Administrator James Webb tasked staffer and artist James Dean with implementing the new program, and with the help of the National Gallery of Art, Dean laid the framework to artistically capture the inspiration of NASA’s Apollo program. As the NASA Art Program continues to evolve, the agency remains focused on inspiring and engaging the next generation of explorers – the Artemis Generation – in new and unexpected ways, including through art.

Sols 4311–4313: A Weekend of Engineering Curiosity
NASA’s Mars rover Curiosity captured this image of its rover wheels using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, on February 5, 2024, Sol 4088 — Martian day 4,088 of the Mars Science Laboratory Mission — on Feb. 5, 2024 at 10:40:14 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Friday, Sept. 20, 2024
Today, we planned for 3 sols over the weekend. On Sol 4311, we have a lot of science activities planned, including some ChemCam and Mastcam observations of the “Obelisk” target. These activities will allow our instruments to gather data about rock features of interest within the rover workspace, including a LIBS analysis which will give us more insight into chemical composition. We will also take some landscape images of the ridges within the upper Gediz Vallis channel.
But we don’t only plan for science activities – as a robotic arm engineer, I’m looking forward to a new in-flight activity we are executing on Sol 4311. We are testing parallelism between arm activities and a telecommunications window between the rover and an orbiter. As we get further and further into the mission, we have been testing what activities we might be able to do in parallel (ie: they are happening at the same time on the rover!) in order to be more efficient during our on time. After this execution, we’ll be able to get more information on how both activities went, and if it was successful, this will be able to save us a lot of time in the future!
On 4312, we have some remote science planned, including a Navcam dust devil movie, a ChemCam active observation, and some Mastcam imaging. Equally exciting, though, is our planned full MAHLI wheel imaging. This is a traverse activity where we do a short drive, take photos of the wheels, do another short drive and take more photos, such that we are getting imaging of the entire circumference of our wheels. This is an activity we do periodically to assess the state and health of the wheels. For full documentation of our wheel state, we will drive seven meters over the course of about three hours. I’ve included an image above of the last time we performed full MAHLI wheel imaging (on Sol 4088).
On 4313, we will execute some more science activities. This includes more remote science with a Navcam suprahorizon movie and a dust devil survey, and ChemCam AEGIS execution. Recall that AEGIS is our autonomous targeting system that will be able to pick out targets of interest around our new location post-drive. We’ll also execute some early morning science including a Mastcam tau atmospheric observation to measure dust in the atmosphere.
From an engineering perspective, I am looking forward to seeing how our parallelism test went, and to view the updated imaging of our wheels. It will definitely be an exciting weekend for our little rover!

Sols 4309–4310: Leaning Back, Driving Back
NASA’s Mars rover Curiosity captured this image of a large fractured slab of bedrock, taken by Right Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4307 — Martian day 4,307 of the Mars Science Laboratory Mission — on Sept. 17, 2024 at 15:50:36 UTC. Earth planning date: Wednesday, Sept. 18, 2024
The lengthy drive planned on Monday executed as expected, and we came in today to find our rover parked at a jaunty angle on a sloped ridge. There were some worries that the slope might limit our ability to use the arm for contact science in this plan (we don’t want to do anything that might cause the rover to slide down the slope!), but after some careful consideration, we received the good news that all six of our wheels are holding on firmly to the ground, so there was no risk of slipping.
On Monday, two different options for today’s plan were laid out. The first option, a “full contact science” plan where we don’t drive, was to be executed if Monday’s drive put us exactly where we hoped. The second, a “touch-and-go” plan where we do some light contact science before driving away, was to be executed if the drive didn’t put us where we wanted to be. As it happened, the rover was a little too enthusiastic about driving, and actually put our desired workspace under its body rather than in front where the arm could reach it. There’s always a little uncertainty in the final position after such a long drive! So, we decided to stick with a touch-and-go plan that includes a tiny backwards drive of less than a metre to reposition our desired target in front of the rover.
Although we need to re-position, we aren’t slowing down on science for even a second. We are parked in front of a large fractured slab of bedrock, which can be seen in the above image. This slab became the contact science target for this plan with DRT and APXS activities on “The Minster.” Mastcam is getting a workout today as well, with large mosaics of “North Channel,” “Buckeye Ridge,” “Quinn,” and “Island Pass.” These mosaics are all documenting various aspects of the ridge we’re sat on and the edge of the Gediz Vallis Channel, including sedimentary rocks, white sulphate materials, and gravels and fine-grained materials. ChemCam is also taking a turn on the bedrock slab with a LIBS activity on “Grand Sentinel” and a mosaic of some exposed white stones off in the distance.
The second sol of the plan, after our short drive, is largely taken over by environmental science activities, though there is our usual post-drive ChemCam AEGIS. These activities include a Mastcam tau and Navcam line-of-sight to measure the amount of dust in the atmosphere around and above us, as well as a dust devil movie, suprahorizon cloud movie, and some Navcam deck monitoring to see if our driving or the wind is moving around any of the sand and dust on the rover deck. The team is also taking the usual set of REMS, RAD, and DAN observations.
