Sols 4359-4361: The Perfect Road Trip Destination For Any Rover!
NASA’s Mars rover Curiosity acquired this image of its workspace, which includes several targets for investigation — “Buttress Tree,” “Forester Pass,” “Crater Mountain,” “Mahogany Creek,” and “Filly Lake.” Curiosity used its Left Navigation Camera on Nov. 8, 2024 — sol 4357, or Martian day 4.357, of the Mars Science Laboratory mission — at 00:06:17 UTC. NASA/JPL-Caltech Earth planning date: Friday, Nov. 8, 2024
After the excitement of Wednesday’s plan, it was a relief to come in today to hear that the drive toward our exit from Gediz Vallis completed successfully and that we weren’t perched on any rocks or in any other precarious position. This made for a very smooth planning morning, which is always nice on a Friday after a long week.
But that isn’t to say that Curiosity will be taking it easy for the weekend. Smooth planning means we have lots of time to pack in as much science as we can fit. Today, this meant that the geology group (GEO) got to name eight new targets, and the environmental group (ENV) got to spend some extra time contemplating the atmosphere. Reading through the list of target names from GEO felt a bit like reading a travel guide — top rocks to visit when you’re exiting Gediz Vallis!
If you look to the front of your rover, what we refer to as the “workspace” (and which you can see part of in the image above), you’ll see an array of rocks. Take in the polygonal fractures of “Colosseum Mountain” and be amazed by the structures of “Tyndall Creek” and “Cascade Valley.” Get up close and personal with our contact science targets, “Mahogany Creek,” “Forester Pass,” and “Buttress Tree.” Our workspace has something for everyone, including the laser spectrometers in the family, who will find plenty to explore with “Filly Lake” and “Crater Mountain.” We have old favorites too, like the upper Gediz Vallis Ridge and the Texoli outcrop.
After a busy day sightseeing, why not kick back with ENV and take a deep breath? APXS and ChemCam have you covered, watching the changing atmospheric composition. Look up with Navcam and you may see clouds drifting by, or spend some time looking for dust devils in the distance. Want to check the weather before planning your road trip? Our weather station REMS works around the clock, and Mastcam and Navcam are both keeping an eye on how dusty the crater is.
All good vacations must come to an end, but know that when it’s time to drive away there will be many more thrilling sights to come!

Sols 4341-4342: A Bumpy Road
This image was taken by Left Navigation Camera aboard NASA’s Mars rover Curiosity on Sol 4329 — Martian day 4,329 of the Mars Science Laboratory mission — on Oct. 10, 2024, at 05:35:08 UTC. NASA/JPL-Caltech Earth planning date: Monday, Oct. 21, 2024
After Curiosity’s busy weekend, the team is ready for another day of planning. We are able to take advantage of the Earth-Mars time offset to full plan on both sols of our plan today. For this plan, I served as Mobility Rover Planner, and planned Curiosity’s drive.
The first sol begins with some remote science. In this block, there is a ChemCam LIBS and Mastcam joint observation of “Ewe Lake,” to look for variation across the different layers in the rock. There is also a ChemCam RMI and a Mastcam of the “Olmstead Point” target, to see if there are chemical differences that make it darker than the surrounding rocks. Mastcam also is taking a stereo image of “Depressed Lake” (in order to see if this loose block belongs to the Stimson or the Sulfate units) and an image of the ChemCam AEGIS target the rover automatically found after the last drive.
After a nap, Curiosity wakes up to do some contact science on the “Chuck Pass” target, which is a piece of bedrock with laminations and nodules. We perform DRT brushing, MAHLI, and APXS observations of this rock before stowing the arm so we can be ready to drive on the second sol. In the late afternoon, to take advantage of the lighting conditions, we have another short set of Mastcam imaging — an atmospheric sky column observation and a stereo mosaic of “Fascination Turret” from this new angle.
The second sol also kicks off with some remote sensing. We follow up the contact science with ChemCam LIBS and Mastcam of Chuck Pass. ChemCam also takes an RMI looking east back to the area of the white sulfur stones below “Whitebark Pass” to get yet another viewing angle. There is also some atmospheric imaging, Navcam deck monitoring (to see how the dust is moving around on the rover’s deck) and a large dust devil survey.
After the imaging, we are ready to drive. This terrain has been very tricky. While the slopes are not steep, this is a very rocky area, as you can see in the image, making finding a safe path difficult. We don’t only need to worry about driving over things that are too big or too sharp, but we also have to make sure not to scrape the wheels along the side of a rock or steer them into a rock, making them wedge and stall. It also means that we do not have good stereo data out very far because the rocks block our view. The last complication is that we have to drive backwards — otherwise, the rover hardware will block Curiosity’s view of Earth during the time we want to send her the new plan. When we drive backwards, the rover hardware will block Curiosity’s view, so we need to turn to get a clear view in our images. We also take additional frames to be sure we can find the best path for the next drive. With all this, we ended up being able to drive about 32 meters today (about 105 feet). After a short diversion to get around a steering hazard, we were able to drive a fairly straight route along the path to our next major imaging stop. After the drive, we have our normal post-drive imaging, including a twilight MARDI image.
We have been lucky so far on this terrain and been able to successfully complete our recent drives. Hopefully this drive will also be successful!

Sols 4327-4328: On the Road Again
This image was taken by NASA’s Mars rover Curiosity using its Left Navigation Camera on sol 4326 — Martian day 4,326 of the Mars Science Laboratory mission — on Oct. 7, 2024, at 01:16:16 UTC. NASA/JPL-Caltech Earth planning date: Monday, Oct. 7, 2024
After successfully completing investigations within Gediz Vallis, Curiosity is back on the road through the Mg-sulfate (magnesium sulfate) bearing unit. The terrain under our wheels is a familiar collection of broken up blocks, and we’re keeping our rover eyes on the more distant stratigraphy and the deposits within the Gediz Vallis channel (as seen in the above Navcam image). Our traverse along this side of the channel is a great chance to understand the erosional and depositional history of Gediz Vallis from a different perspective, and to characterize variations in the sulfate unit.
I was on shift as Long-Term Planner today, and it was a pretty straightforward two-sol plan, with contact science on the first sol and driving on the second sol. The team planned a great collection of measurements to characterize the rocks in our workspace and more distant features.
The plan starts with remote sensing, including ChemCam LIBS on a gray, smooth slab at “Paloma Meadows,” followed by two long-distance RMI mosaics to assess the thickness and distribution of white clasts in Gediz Vallis. Then Mastcam will document Paloma Meadows and a distant dark clast at “Sky Parlor Meadow” to understand the variety of rock types and where they might have come from. The remote sensing block also includes a Navcam observation to search for dust devils. Later in the afternoon Mastcam will acquire a mosaic looking back towards “Whitebark Pass” including the white clasts (some of which were previously tied to observations of high sulfur) and the distribution of deposits within “Pinnacle Ridge.” Then Curiosity will use the instruments on the arm to assess one of the blocks in our workspace at “Pincushion Peak.” We’ll use the DRT, MAHLI, and APXS to assess the grain size, textures, and composition of a nodular block of bedrock. On the second sol Curiosity will acquire ChemCam LIBS and Mastcam of Pincushion Peak, which will make for a nice set of coordinated observations. The second sol also includes a long-distance RMI mosaic of an interesting dark block to assess sedimentary structures, and two Navcam observations to characterize atmospheric opacity and the movement of fines on the rover deck. Then Curiosity will continue driving, and take post-drive imaging to prepare for a similar plan on Wednesday. Looking forward to continuing to explore what’s under our wheels and on the horizon!

Sols 4289-4290: From Discovery Pinnacle to Kings Canyon and Back Again
This image shows the workspace in front of NASA’s Mars rover Curiosity, taken by the Left Navigation Camera aboard the rover on sol 4287 — Martian day 4,287 of the Mars Science Laboratory mission — on Aug. 28, 2024, at 02:23:27 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Aug. 28 2024
We are back … almost, anyways. Today’s parking location is very close to where we parked on sol 4253, and in an area near one of the previous contact science targets “Discovery Pinnacle.” You can read in this blog post that most of the team, this blogger included, was in Pasadena for our team meeting when we were last in this area. That was July and Curiosity was about to turn 12 on Mars. Coming back is a very rare occasion and is always planned carefully. Once or twice during the last 12 years it happened because we saw something “in the rear mirror.” One of the examples is the target “Old Soaker,” where we spotted mud cracks in the images from a previous parking position, and promptly went back because this was such an important discovery. At other times it was carefully planned, such as the “walkabout” at “Pink Cliffs,” which you can watch in this video from as long back as Earth year 2015. In the past few planning cycles, it’s more of the latter as we made our way from Discovery Pinnacle, where we were on sol 4253, “Just passing through” “Russell Pass” and arriving at “Kings Canyon,” our drill location, which we reached on sol 4257. You can follow all the action of the drilling at Kings Canyon on the blogs. It took a while — it always does — because it’s an activity with many steps and investigations to complete. We actually celebrated Curiosity’s 12th birthday at Kings Canyon! We departed on sol 4283, came back via “Cathedral Peak,” and are now near the Discovery Pinnacle location again. After that little walkabout through the history of (some) of Curiosity’s walkabouts, especially the very last one, let’s look at today’s plan.
It is a pretty normal two-sol plan, with a one-hour science block before we drive away from this location. We were greeted by a nicely flat surface, and the engineers informed us that we have all six wheels firmly on flat and stable ground. That’s always a relief, because only then can we use the arm. That nice piece of flat rock Curiosity is so firmly parked on became our science target …well, mostly. Some of the little pebbles on the surface attracted our attention, too. The very eagle-eyed can spot a small white spot in the image above. It’s right between the arm and the rover itself, about where the C is written. That’s a rock that we likely broke up with our wheel and that has a very white part to it. We called it “Thousand Island Lake,” and will image it with MAHLI. APXS is investigating a target called “Eichorn Pinnacle,” squarely on the big flat area. LIBS is also making the most of the large target underneath and in front of us, investigating the target “Nine Lakes Basin.”
In recent blogs you will have read about the dust-storm watch making the atmospheric investigations even more important, so we don’t miss any changes. We are looking for dust devils, atmospheric opacity, and are of course monitoring the weather throughout the plan.
Our drive will hopefully — if Mars agrees — be a long one, and we will also plan an activity that we call MARDI sidewalk. That’s when we take very frequent pictures with the MARDI instrument while driving. This results in a long strip of images nicely showing the nature of the terrain the rover has driven over. This is in addition to the MARDI single frame we are taking every time the rover stops. I often get the question, why are we taking an image just downwards whenever the rover stops? Well, humans are easy to bias toward the outliers, toward the things that look special, and of course the Curiosity team is no exception. For some things this is great, because it allows for the discoveries of new things. But it doesn’t provide an unbiased overview. That’s what MARDI does: It always points down and reliably records the terrain under the rover. We don’t have to do anything but put the commands for that one image into our plan after the drive — something that’s pretty routine after 12 years now!

Sols 4287-4288: Back on the Road
This image was taken by Mast Camera (Mastcam) aboard NASA’s Mars rover Curiosity on Sol 4284 — Martian day 4,284 of the Mars Science Laboratory mission — on Aug. 24, 2024, at 20:32:43 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday, Aug. 26, 2024
Today’s planning day was a good example of how our team comes together to make quick decisions based on new information and science priorities.
The original intent of today’s plan was to perform contact science on some interesting bright-toned rubbly rocks in our workspace, seen in the image above. These rocks were just a short bump away from the location of our last sampling campaign and the team had been eyeing them for a few weeks, interested in the details of their composition from the APXS instrument and their morphology from MAHLI. However, before we ever unstow our robotic arm to perform these types of observations, our Rover Planners and Surface Property Scientists perform a “Slip Risk Assessment.” This assessment is used to determine whether the rover’s wheels are stable on the ground so that we can safely unstow the heavy robotic arm and place the arm-mounted instruments very close to the surface. In today’s case, the team determined that it was not safe to unstow our arm. If the science team was interested in observing the bright-toned rocks in our workspace, it would require adjusting the rover’s position and performing the observations in the next planning cycle, impacting our overall mission timeline.
With this information on hand, the science team had an excellent discussion, quickly assessing the pros and cons of sticking around with a small adjustment to get contact science at this location in our next plan, or continuing down the road to our next waypoint. I always enjoy listening to these discussions; they are led by our Long-Term Planners and provide the opportunity for all science advocates to voice their opinions. In today’s case, the science team decided to move along. This location had been opportunistic to begin with and more juicy science targets are certainly to come. Time is a precious resource to us, and we often consider the timeline cost of any given science observation, weighing the relative science benefit to the cost of planning cycles.
So given this reworking of priorities, today’s two-sol plan was adjusted to include targeted science on the first sol before driving away towards our next waypoint, followed by another sol with untargeted science. Our drive takes us about 25 meters north and we’ll pause part way through the drive to take Mastcam imaging of some bright nodular-appearing rocks to examine their relationship to other rock types.
Between the two sols of this plan, we’ll perform an empty-cell analysis of the CheMin cell used for our last sampling campaign, to determine if we have dumped all the sample out of it for future use with another sampling campaign. As always, we performed our normal environmental monitoring observations.
Onward, Curiosity!
