NASA has published new photos taken by its venerable Mars Rover Opportunity, which after 14 Earth years and 5,000 Sols – Martian days – continues its scientific mission on the planet Mars. In the ancient valley called Perseverance Valley it found a soil with a texture that resembles certain very particular rock strips on some mountain slopes on the Earth. These formations can be created by cycles of freezing and thawing of moist soil or wind, downhill transport or other processes.

NASA has published photographs of star-shaped and swallowtail rock formations discovered by the Mars Rover Curiosity during the exploration of the area of Gale Crater on Mars called Vera Rubin Ridge. This ridge is offering interesting research cues, in this case gypsum crystals similar to those found in lakes that dried up on Earth, for example in Scotland. This is another clue of the fact that in Gale Crater in ancient times there was a lake.

NASA has published a series of images taken by its Mars Rover Curiosity in the Gale Crater area of Mars called the Vera Rubin Ridge created putting together photos taken using filters that allow the mission scientists to identify some minerals. The instruments that have this capability are the MastCam (Mast Camera) and ChemCam (Chemistry and Camera). On this occasion, the MastCam allowed to highlight an iron oxide called hematite.

NASA’s Mars Rover Opportunity is working in an ancient valley on the edge of Endeavour Endeavour’s rim called “Perseverance Valley” examining rocks and driving around the area to carry out a survey of the place. According to plans, once these tasks are completed Opportunity will go down to the lower part of the valley but the maneuver will have to be even more cautious than expected due to a problem encountered in one of the wheels’ steering system.

An article published in the journal “Earth and Planetary Science Letters” describes a study of the first samples taken in the lower layers of Mount Sharp on Mars by NASA’s Mars Rover Curiosity. A team of scientists in the ARES Division at NASA’s Johnson Space Center compared the minerals found in the first samples analyzed, which show the different environmental conditions that existed over time.
