This photo was selected by public vote and featured as “Image of the Week” for Week 244 (Oct. 12 – 18, 2025) of the Perseverance rover mission on Mars.

NASA's Mars Perseverance rover acquired this image, a nighttime mosaic of the Malgosa Crest abrasion patch at “Serpentine Rapids,” using its SHERLOC WATSON camera, located on the turret at the end of the rover's robotic arm. The diameter of the abrasion patch is 5 centimeters (about 2 inches) and the large green spot in the upper center left of the image is approximately 2 millimeters (about 0.08 inch) in diameter. Mosaic source images have been debayered, flat-fielded, and linearly color stretched. This image was acquired on Aug. 19, 2024 (sol 1243, or Martian day 1,243 of the Mars 2020 mission) at the local mean solar time of 19:45:30. NASA/JPL-Caltech Larger image

Editor’s note: I will make this simple: did NASA find evidence of life on Mars? No. Did NASA find an interesting rock feature that might signal or indicate that there […]
