SPATIU - MARTE - PERSEVERANCE ROVER
July 25, 2024: This image shows: NASA's Perseverance Mars rover used its Mastcam-Z instrument to view this workspace around the sample collected from a rock nicknamed ''Cheyava Falls.'' A drill hole is visible (far left) where a sample was collected on July 21, 2024. At right is a rock nicknamed ''Steamboat Mountain.'' A circular white abrasion patch can be seen on each rock; these are where the rover used an abrasion tool to clear away the top surface, allowing instruments to study the rocks' composition...The images that make up this composite were taken by the rover's Mastcam-Z instrument on July 23, 2024, the 1217th day, or sol, of the mission...NASA’s Perseverance rover has discovered a rock on Mars that contains what scientists believe may be signs of ancient life..The rock, dubbed “Cheyava Falls†by the rover’s science team, exhibits intriguing characteristics that suggest it may have hosted life billions of years ago..Analysis conducted by Perseverance’s onboard instruments indicates that a core sample contains chemical signatures and structures potentially formed by life when the area was rich with flowing water. While these features could indicate ancient microbial life, alternative explanations are still being considered, and further research is essential to confirm this hypothesis..The rock, which is the rover’s 22nd rock core sample, was collected on 21 July as the rover navigated the northern edge of Neretva Vallis. This ancient river valley, measuring a quarter-mile wide, was once carved by water flowing into Jezero Crater..Nicola Fox, associate administrator of the Science Mission Directorate at NASA Headquarters, remarked on the significance of the find: “This trip through the Neretva Vallis riverbed paid off as we found something we’ve never seen before, which will give our scientists so much to study.â€.Ken Farley, Perseverance project (Credit Image: © Cover Images via ZUMA Press)
