The dark blocks that occasionally appear in the rover’s path are called floating rocks, and the team is looking higher into the hills to determine their origin. As intriguing as these blocks and boulders are, they pose a serious challenge for the rover’s drivers. They managed to get the rover to its intended stopping point, which is a significant achievement in itself. The mixture of large rocks and sand is completely unfavorable for movement. The risk of the rover shifting at the wrong moment, and the robotic arm colliding with a rock that the instrument is currently exploring, would be too great.<\/span><\/p>\n

On December 5, 2024, the rover successfully arrived at a new exploration quadrangle\u2014the Altadena quadrangle<\/span><\/strong><\/span>, named after the city on Earth located very close to the Jet Propulsion Laboratory. The initial activity in the Altadena quadrangle was fairly typical, including observations both near and far from the rover, depending on what was visible on the ground. Thousands of meters from the rover (five-eighths of a mile and beyond), ChemCam captured a mosaic of wind-sculpted structures known as yardangs crowning Mount Sharp.<\/span><\/p>\n

On December 8, 2024, the rover continued to navigate the large Texoli hill. Much of the bedrock it recently traversed looked quite similar\u2014pale, layered bedrock\u2014but this workspace had several interesting features, including a “direction of travel” image that shows the rover’s future route.<\/span><\/p>\n

There were numerous cracks and darker areas near the rover. The cracks or veins were too far from the rover for contact science, but ChemCam LIBS was able to target one of the most prominent ones in the “Garlock Rift.” Fortunately for the contact science instruments (APXS and MAHLI), the darker areas were within arm’s reach. Some of the darker areas were flatter and plate-like in appearance, while others had a more amorphous, teardrop-shaped shape. Both types have their own challenges. The flatter ones collect dust on their flat surfaces, so ideally they should be cleaned with a DRT (dust removal tool) before we analyze them, but they often appear too fragile, and we worry that some of the layers may chip or peel off. The amorphous ones have uneven surfaces that can collect sand and dust, making it difficult to achieve a good placement.<\/span><\/p>\n

On December 12, 2024, Curiosity continued to make steady progress through the bedrock of Mount Sharp and spent time exploring the northern base of Texoli Hill, with beautiful views of nearby Wilkerson Hill and Gould Mesa, while digging around the work area to complete an impressive to-do list for a traveling geologist on Mars.<\/span><\/p>\n

The rocks beneath the rover’s wheels were dusty, pale bedrock with varying textures. Scientists used the Dust Removal Tool (DRT), MAHLI, and APXS instruments to study the lighter, smoother bedrock at Calabasas Peak and the slightly darker, coarser bedrock at Triunfo Canyon. The ChemCam team used laser-induced emission spectroscopy (LIBS) to analyze the composition of the coarser bedrock at Chilao Peak and a vein cutting through the bedrock at Ojai Peak, and Mastcam provided imagery to document each target.<\/span><\/p>\n

On February 5, 2025,<\/span><\/strong><\/span>\u00a0Mars reached 40 degrees solar longitude. Solar longitude is how we prefer to measure our position in the Martian year. Each year begins at 0 degrees and increases to 360 degrees by the end of the year. For those working on the Environmental Science Ventures (ENV) team, 40 degrees is a special time, as it marks the beginning of the annual Aphelion Cloud Belt (ACB) observation campaign. At this time of year, the north polar ice cap is exposed to sunlight, causing it to sublimate and release water vapor into the atmosphere. At the same time, the atmosphere as a whole is cooler because Mars is near aphelion (its greatest distance from the Sun).<\/span><\/p>\n

Together, these two factors mean that Mars’ atmosphere is actively forming clouds at this time of year.<\/span><\/p>\n

The drive ended prematurely, having traveled only about 4 meters instead of the planned 38 (about 13 feet versus 125 feet). Initially, the research team thought this might be due to the rover’s left front wheel hitting a large rock, but after motion data was collected, it turned out that the right front wheel’s steering motor was also signaling a rock on that side, so Curiosity stopped driving, awaiting further instructions from Earth.<\/span><\/p>\n

Color images taken with Mastcam will reveal more about the textures of this rock and perhaps shed light on the geological forces that shaped it into this comical shape. The team has chosen a very appropriate name for this pyramid-shaped Martian feature: Pyramid Lake.<\/span><\/p>\n

On the second sol of the plan, instruments on Curiosity’s “arm” were used to collect data on rocky features at our feet, including “Strawberry Peak”\u2014a jagged patch of bedrock; “Lake Arrowhead”\u2014a smooth patch of bedrock; and “Skyline Trail”\u2014a dark floating rock.

Sol 4458-4460: Winter Schminter, February 18, 2025.<\/span><\/strong><\/span>\u00a0Operating Curiosity on Mars requires attention to a number of factors\u2014power, data volume, terrain roughness, temperature\u2014that impact the rover’s performance and safety. Winter means more heat to warm the rover’s gears and mechanisms and instruments, but the energy spent on heating means less energy for science observations.<\/span><\/p>\n

The goal of additional Mastcam and ChemCam images was to document a feature that, unlike Marker Band, had been and would be in the rover’s field of view for a long time: Texoli Hill. Observations of potential sedimentary structures on the slope of Texoli motivated the RMI mosaic, and the opportunity to capture structures along its southeastern flank inspired the Mastcam mosaic. Good exposures of additional nearby bedrock structures on Mount Lukens and Chantry Flat attracted Mastcam attention, while another small mosaic focused on a type of linear depression in the sand bordering bedrock slabs. Environmental observations included Navcam movies of clouds and dust devils, Mastcam observations of atmospheric dust, and REMS and RAD measurements distributed over three sols.<\/span><\/p>\n

Although the previous plan successfully advanced the rover approximately 21 meters south (about 69 feet), the drive ended with an awkwardly positioned wheel. Unfortunately, this made it too risky to open the robotic arm for contact exploration as part of this plan.<\/span><\/p>\n

Several close-range Mastcam mosaics captured some layering and diagenetic structure in adjacent blocks, as well as some modern aeolian depressions in the finer-grained material around them.<\/span><\/p>\n

The season on Mars (L_s ~ 50, or solar longitude near 50 degrees, approaching the southern winter) brings with it the opportunity to observe some recurring atmospheric phenomena: this is the season of the aphelion cloud belt, as well as the season of the Hadley cell transition, during which a more southerly air mass crosses Gale Crater.<\/span><\/p>\n

This plan includes atmospheric observations with APXS (without moving your hand!) to measure argon and passive sky observations with ChemCam to measure O2, which is a small (less than 1%) but measurable component of the Martian atmosphere. The plan also includes dedicated cloud height observations, sky phase analysis, and video acquisition at the zenith and below the horizon to study clouds. As usual, the rover continues to monitor the current environment, measuring atmospheric opacity with images, temperature and humidity with REMS, and the local neutron environment with DAN.<\/span><\/p>\n

Sols 4473-4474, March 5, 2025.<\/span><\/strong><\/span>\u00a0This image shows a rather unusual texture next to more ordinary-looking layered rocks. Just compare the small, lighter block in the foreground with the darker, larger rock in the center of the image. How to interpret this? Well, that’s the question. Did these sedimentary textures form at the time the rock was deposited, or shortly thereafter, or are they textures that formed much later, when water infiltrated the rock and formed new minerals within the existing rock?<\/span><\/p>\n

The landscape immediately surrounding the rover also features interesting textures and, most importantly, more familiar-looking bedrock. The team defines bedrock as the rocks that make up the portion of the hill Curiosity is driving over. Dark blocks like the one shown here, which also occasionally appear along the rover’s path, are called floating rocks, and we always look higher into the hills to figure out where they might have come from. As interesting as all these blocks and boulders are, they pose a serious challenge for the rover’s drivers. They managed to get the rover to its intended stopping point, which is a significant achievement in itself. The mixture of large rocks and sand is completely unfavorable for movement. The risk of the rover shifting at the wrong moment and the robotic arm colliding with a rock the rover is currently exploring would have been too great.

At the center of the rover’s work area was a large patch of soil and sand, which MAHLI and APXS jointly explored in the vicinity of a target named “Angeles Crest.” Nearby, Mastcam photographed depressions (depressions) along the axis of the sand ridge to understand their formation mechanisms. Mastcam’s map included several other targets that imaged the work area and surrounding areas, including “Potrero John,” a knobby rock within the work area; a rock with a similar knobby texture in the distance called “Modjeska Peak”; and a light-brown rock with a dome-shaped structure in the area of \u200b\u200b”Humber Park.”<\/span><\/p>\n\n

ChemCam selected a bedrock slab and loose rock within the study area to study their geochemical characteristics using the LIBS instrument at Millard Canyon and Cajon Pass, respectively.

One observation, at the Yerba Buena Ridge target, encompasses the structures evident along the outcrop front in the image above. The second target, Sepulveda Pass, has an interesting texture that required several stereo imaging options. The final target MAHLI shared with APXS was the South Fork target. This was the clearest location for APXS to deploy onto uncut bedrock blocks.<\/span><\/p>\n

ChemCam also provided chemical data on a number of targets with varying textures. The “Ridge Route” target covered low-lying bedrock with fine layering consistently observed in the sulfate sequence, while “Toyon Canyon” covered a more lumpy portion of the Humber Park outcrop above Yerba Buena Ridge. The “Mount Lawlor” target was a mixture of both Ridge Route and Toyon Canyon\u2014layered but located on an elevated portion of the outcrop, which also featured several unusual depression chains. ChemCam added two long-range mosaics of “Gould Mesa,” which captured various structures on this impressive hill approximately 100 meters ahead of the rover.<\/span><\/p>\n

Mastcam focused on covering the entire Humber Park with a stereo mosaic, adding smaller mosaics across a sand trough and a bedrock block with potential cross-bedding in Rancho Los Feliz.

NASA’s Mars rover Curiosity captured this image of its footprints on July 26, 2025.<\/span><\/strong><\/span>\u00a0The robotic scientist is exploring the area at the base of Mount Sharp, a 5-kilometer (3-mile) high mountain. The mountain’s pale peak is visible at the upper right; the rim of Gale Crater, where the mountain is located, is visible on the horizon at the upper left. Curiosity landed on the crater floor 13 years ago.<\/span><\/p>\n

A month earlier, the rover entered an area filled with box-shaped formations. Studying these formations could help determine whether microbial life could have survived in the depths of Mars billions of years ago, extending the planet’s habitability even further during its drying period.<\/span><\/p>\n

The dark blocks that occasionally appear in the rover’s path are called floating rocks, and the team is looking higher into the hills to determine their origin. As intriguing as these blocks and boulders are, they pose a serious challenge for the rover’s drivers. They managed to get the rover to its intended stopping point, which is a significant achievement in itself. The mixture of large rocks and sand is completely unfavorable for movement. The risk of the rover shifting at the wrong moment, and the robotic arm colliding with a rock that the instrument is currently exploring, would be too great.<\/p>\n","protected":false},"author":1,"featured_media":2069,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[542,40],"tags":[959,958,647],"class_list":{"0":"post-2068","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-mars","8":"category-kosmos","9":"tag-box-shaped-structures","10":"tag-curiosity","11":"tag-mars-rover"},"_links":{"self":[{"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/posts\/2068","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/comments?post=2068"}],"version-history":[{"count":4,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/posts\/2068\/revisions"}],"predecessor-version":[{"id":2219,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/posts\/2068\/revisions\/2219"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/media\/2069"}],"wp:attachment":[{"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/media?parent=2068"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/categories?post=2068"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/planeta21vek.ru\/eng\/wp-json\/wp\/v2\/tags?post=2068"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
