Sols 4321-4322: Sailing Out of Gediz Vallis
This image was taken by Front Hazard Avoidance Camera (Front Hazcam) aboard NASA’s Mars rover Curiosity on Sol 4319 — Martian day 4,319 of the Mars Science Laboratory mission — on Sept. 29, 2024 at 21:31:07 UTC. NASA/JPL-Caltech Earth planning date: Monday, Sept. 30, 2024
For the past few plans, Curiosity has been wrapping up its science campaign within Gediz Vallis. Over the weekend, the rover completed analyses on white stones encountered while departing the channel, before continuing along the western margin of Gediz Vallis. As we exit the channel, a metaphorical red buoy to our left, uncharted terrain lay ahead.
Today’s two-sol plan commenced with APXS and MAHLI completing a thorough sounding of the target “Flat Note Lake,” the seemingly brighter rock in the left-middle of the image just below a darker cobble and on the margin of swell-like sand ripples. Curiosity also focused ChemCam’s telescope on several key beacons in the landscape. The first target, “Cactus Point,” received a number of laser shots from ChemCam, akin to signaling with a lighthouse to assess its elemental message back to the ship. ChemCam’s RMI captured high-definition mosaics of key formations including rugged yardangs, formations that would not take too kindly to contact with a vessel’s hull. Mastcam complemented these observations with its own survey of the local area, capturing targets that included “Tombstone Ridge,” “Balloon Dome,” “Pinnacle Ridge,” “Clyde Spires,” “Confusion Lake” and “Pilot Peak” in addition to Cactus Point. A lengthy DAN passive measurement was completed in parallel, akin to a depth sounder probing the terrain beneath our hull. With the scientific reconnaissance of the first sol complete, Curiosity tested its metaphorical rigging in the form of trying out some Feed-Extended Sample Transfer arm activities in parallel with a telecommunications window before setting course out of the channel. This is similar to the test we did sols 4311-4313, and will hopefully help us become more efficient in the future.
The second sol of the plan was primarily focused on gathering environmental data and performing post-departure imaging in preparation for Wednesday’s plan, analogous to a ship trimming its sails and adjusting the helm as it exits a sheltered cove. ChemCam completed a calibration activity, fine-tuning its sextant in preparation for its next round of observations. Environmental monitoring and a SAM activity rounded out the second sol of the plan.

Sols 4302-4303: West Side of Upper Gediz Vallis, From Tungsten Hills to the Next Rocky Waypoint
This photo taken by NASA’s Mars rover Curiosity of ‘Balloon Dome’ covers a low dome-like structure formed by the light-toned slab-like rocks. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4301 — Martian day 4,301 of the Mars Science Laboratory mission — on Sept. 11, 2024, at 09:14:42 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Sept. 11, 2024
The rover is on its way from the Tungsten Hills site to the next priority site for Gediz Vallis channel exploration, in which we plan to get in close enough for arm science to one of the numerous large dark-toned “float” blocks in the channel and also to one of the light-toned slabs. We have seen some dark blocks in the channel that seem to be related to the Stimson formation material that the rover encountered earlier in the mission, but some seem like they could be something different. We don’t think any of them originated in the channel so they have to come from somewhere higher up that the rover hasn’t been, and we’re interested in how they were transported down into the channel.
We aren’t there yet, but the 4302-4303 plan’s activities include some important longer-range characterization of the dark-toned and light-toned materials via imaging. Context for the future close-up science on the dark-toned blocks will be provided by the Mastcam mosaics named “Bakeoven Meadow” and “Balloon Dome.” The broad Balloon Dome mosaic also covers a low dome-like structure formed by the light-toned slab-like rocks (pictured). Smaller mosaics will cover a pair of targets that include contacts where other types of light-toned and dark-toned material occur next to each other in the same block: “Rattlesnake Creek” which appears to be in place, and “Casa Diablo Hot Springs,” which is a float.
The rover’s arm workspace provided an opportunity for present-day aeolian science on the sandy-looking ripple, Sandy Meadow. Mastcam stereo imaging will document the shape of the ripple, while a suite of high-resolution MAHLI images will tell us something about the particle size of the grains in it. The modern environment will also be monitored via a suprahorizon observation, a dust devil survey, and imaging of the rover deck to look for dust movement.
The workspace included small examples of the dark float blocks, so the composition of one of them will be measured by both APXS and ChemCam LIBS as targets “Lucy’s Foot Pass” and “Colt Lake” respectively.
In the meantime, the Mastcam Boneyard Meadow mosaic will provide a look back at the Tungsten Hills dark rippled block along its bedding plane to try to narrow down the origin of the ripples and the potential roles of water vs. wind in their formation.
Communication remains a challenge for the rover in this location. During planning, the rover’s drive was shifted from the second sol to the first sol in order to increase the downlink data volume available for the post-drive imaging, thereby enabling better planning at the science waypoint we expect to reach in the weekend plan. However, maintaining communications will require the rover to end its drive in a narrow range of orientations, which could make approaching our next science target a bit tricky. We’ll find out on Friday!
