Sols 4321-4322: Sailing Out of Gediz Vallis

A grayscale, extreme wide-angle, or fish-eye, view of Martian terrain shows a large butte in the distance, on the exaggerated, curved horizon. In the middle of the image, medium gray soil, looking like windblown sand, dominates the scene. In the foreground, amid a shadow of parts of the rover at the bottom of the frame, numerous very bright-toned rocks stand out from the darker surrounding soil.
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.

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.

A grayscale photograph of the Martian surface from the Curiosity rover captures medium gray, very uneven terrain in front of the rover, with many angular, lighter-toned, medium-sized rocks protruding from the smooth soil. The bottom of the frame shows part of the rover, running from the middle left to the lower right corner of the image, including part of its robotic arm which carries a nameplate imprinted with “Curiosity” outlined in all capital letters, and to the right of that a line drawing of the rover.

A grayscale photograph of the Martian surface shows, in the foreground, medium gray soil that looks like wind-blown sand dunes, with a few rounded, medium-sized rocks poking up from the ground. Beyond this area, and covering the upper half of the frame in this circular image, is much more rocky terrain, with both sharp and rounded rocks of all sizes covering the ground.

Sols 4368-4369: The Colors of Fall – and Mars

A grayscale landscape photo from Mars, showing a broad, medium gray, rock-strewn plain in the foreground extending far into the distance, surrounded by several hills. The closest hill, in the lower right corner, rises up toward the side of the frame, and is darker than the floor below. A little farther out, on the left, a gentle slope rises from the low middle of the frame to middle of the left side; it’s about the same color as the valley floor, except for a band at its farthest edge, which darkens abruptly as if covered in shadow. The terrain appears softer than the ground below, more sandy than rocky. Beyond that along the same rising plane is a much lighter area, with scattered tiny peaks that are darker – looking like the top of a baked meringue pie. The channel floor runs between these hills, then appears to curve toward the right, behind the first hill and in front of the second. Finally, one other rounded peak appears above the horizon, behind these other two hills in the lower right of the frame, all of this below a light-gray sky filling more than half of the frame above.
