Curiosity Blog, Sols 4968-4974: Rock Climbing Towards the Discontinuity
NASA’s Mars rover Curiosity acquired this image, a frame of the “Longquimay” mosaic showing fine-scale sedimentary textures in a bedrock block near the supersurface, using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm. Curiosity acquired the image on Aug. 1, 2026 — Sol 4972, or Martian day 4,972 of the Mars Science Laboratory mission — at 23:35:43 UTC.

Earth planning date: Friday, July 31, 2026
As mentioned in the previous blog, Curiosity has been exploring a large-scale feature in Gale’s sedimentary record suspected to be an “erosional supersurface.” The “supersurface” represents a period in time when a net depositional environment changed to a net erosional one before returning to a depositional regime, thus producing a discontinuity in the rock record. The erosion can involve wind, water, or both. Sometimes there are clues about these environmental changes in the layers below and above the supersurface. So far we’ve been seeing some patterns that look like aeolian features and also some “lens” deposits that sometimes appear consistent with fluvial origins. We need higher-resolution imaging of these features.
This week Curiosity came within detailed imaging range of a section of the “Cerro Paine Grande” vertical exposure just below the candidate supersurface before climbing on top of it. Mastcam was the star of the show on both planning days this week, capturing large stereo mosaics of the vertical face of the outcrop and a 360-degree panorama after the rover climbed on top of it.
NASA’s Mars rover Curiosity acquired this image, showing the rover arm in action in the “Longquimay” workspace at the top of a steep climb. Curiosity captured the image using its Right Navigation Camera on Aug. 2, 2026 — Sol 4972, or Martian day 4,972 of the Mars Science Laboratory mission — at 00:49:52 UTC.

Roving to the top took full advantage of Curiosity’s climbing capabilities, leaving the rover at an approximate 24-degree tilt in its final parking spot. The rover planners managed to reach the right posture for contact science at the same time — quite a feat, and one that approached the mission’s contact science tilt record of 27 degrees!
Meanwhile, MAHLI and our geochemical instruments provided detailed characterization of the rock layers beneath the discontinuity. I was the Geology and Mineralogy Theme Lead for the Sol 4968 (Monday) planning cycle, during which “Puyehue” in the light-toned bedrock block of the workspace was co-targeted with APXS, MAHLI, and ChemCam LIBS. The other two targeted LIBS observations in the plan went to a similar-looking nearby bedrock block (“Lago Palena”) and an intriguing layered block off to the side of the workspace (“Piedras Juntas”). Another APXS measurement went to a sand target, “Cormudesi,” which will help us assess the consistency of sand compositions along the rover’s traverse.
In the Sol 4972 workspace atop the slope, the bedrock was sharply divided between a smooth bedding-parallel surface on the local top of the outcrop and the darker-toned, rougher, angled exposure of the same rocks. The light-toned top surface was measured by MAHLI, APXS, and the LIBS at target “Sierra de Sangre,” whereas the darker-toned laminated face was targeted by APXS and MAHLI at “Laguna del Laja.” The fine-scale sedimentary structures in the textured material were also documented by a MAHLI mosaic (“Longquimay”) supported by Mastcam M100 imaging.
Rounding out the week’s science observations were several long-distance ChemCam RMI mosaics on more distant targets such as sedimentary structures above the rover’s current stratigraphic position, and finally our regular cadence measurements of the modern Martian environment, including atmospheric opacity and a ChemCam passive-sky survey to monitor abundances of minor atmospheric gases.

Six Moons of Saturn
Explanation:How many moons does Saturn have? While the total will likely continue to grow, as of June 2026 the ringed gas giant had 293 confirmed moons. That’s easily more than any other planet of the Solar System, including ruling gas giant Jupiter with a mere 115 confirmed moons. Most of Saturn’s known moons are small, irregular satellites. Many are only few kilometers to a fraction of a kilometer across and grouped in tilted outer orbits. Six of its largest satellites can be seen here, though, in this sharp telescopic Saturnian family portrait taken on August 5. Larger than Earth’s Moon and even slightly larger than inner planet Mercury, Titan, with a diameter of 5,150 kilometers, is at lower right. You can also spot icy major moons Mimas, Tethys, Enceladus, Dione, and Rhea in the frame. Saturn’s first known natural satellite, Titan was discovered in 1655 by Dutch astronomer Christiaan Huygens. During the space age Voyager and Cassini discoveries have added to the swelling ranks of Saturnian moons.

Editor’s Note: Today’s story is the answer to the August Puzzler.
Tides are among the clearest signs of the Moon’s pull on Earth. Just 239,000 miles (385,000 kilometers) away, the Moon’s gravity pulls on Earth’s oceans and solid crust, subtly distorting them into a more oblong shape with bulges roughly extending toward and away from the Moon.
High tides happen throughout Earth’s oceans, but in some places they leave an unusually strong fingerprint on the landscape. Among those places is Roebuck Bay, a crescent-shaped feature in the Kimberley region of Western Australia.
Roebuck Bay’s tidal range can reach a remarkable 9 meters (30 feet). Rising and falling tides repeatedly inundate and expose expansive mudflats, flood broad mangrove forests and salt marshes, and feed branching networks of tidal drainage channels. Many parts of Australia have tidal ranges of 2 meters or less. But the large range at Roebuck Bay is mostly a consequence of northwestern Australia’s unusually wide, shallow continental shelf, which helps amplify tides as they approach the coast.
The image at the top of the page shows the bay on March 18, 2026, when water levels were high. Green mangrove forests grow thickly along the shoreline and line the mouths of a network of evenly spaced, linear tidal creeks. These mangrove forests are dynamic. Analysis of decades of Landsat observations shows them expanding westward by nearly 2 meters per year as sediment from the waterways to the east accumulates in the sheltered bay.
Farther inland, branching networks of tidal drainage channels connect with the tidal creeks, giving the bay its feathered appearance. These channels, partially obscured by thick vegetation in March, were more visible earlier and later in the year, when vegetation was thinner.
Around Roebuck Bay, inland vegetation greens after monsoon rains, peaking in March, and turns brown and dry by June. The Landsat 8 and 9 satellites captured these images throughout 2026.

Monsoonal rains, typically falling between December and March, transform the landscape around the bay into lush grasslands and seasonal wetlands. As the rains fade in May and June and the dry season takes hold, these ephemeral grasses and sedge ecosystems die back, turning the landscape shades of gold and brown. The consistent spacing of the tidal creeks is likely not a tidal effect; it appears to be influenced by the regular spacing of linear dunes in the broader region, as seen in the plains to the east.
The bay’s dramatic tidal and seasonal changes are striking from above, and they also support a bounty of life on the ground. The mangroves serve as nurseries for crustaceans and fish, and the mudflats teem with dozens of types of invertebrates, including snails, worms, crabs, clams, and cockles. Shells and snails can reach an abundance of 2,500 per square meter, according to the Australian government.
This bounty of marine life is a major draw for birds. The bay, one of the most important sites for migratory birds in Australia and a key stop on the East Asian-Australasian Flyway, regularly hosts hundreds of thousands of birds, including plovers, godwits, and knots.
