This image from NASA’s Mars Perseverance rover, a fusion-processed SuperCam Remote Micro Imager (RMI) mosaic, shows part of the “St. Pauls Bay” target, acquired from the lower Witch Hazel Hill area of the Jezero crater rim. The image reveals hundreds of strange, spherical-shaped objects comprising the rock. Perseverance acquired this image on March 11, 2025, or sol 1442 — Martian day 1,442 of the Mars 2020 mission.

Mars Perseverance Examines A Rock With Hundreds Of Millimeter-sized Spheres

by Keith CowingMarch 25, 2025March 25, 2025

Last week the Perseverance Science Team were astonished by a strange rock comprised of hundreds of millimeter-sized spheres and the team are now working hard to understand their origin.

Perseverance Observes Unusual White Float Rocks On Mars

by Keith CowingNovember 15, 2024November 15, 2024

During its recent exploration of the crater rim, Perseverance diverted to explore a strange, scattered field of bright white rocks which sparked the interest of the team scientists.

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

Mars Perseverance Rover Observes Red Rocks With Green Spots at Serpentine Rapids – Possible Biosignatures?

by Keith CowingOctober 27, 2024October 27, 2024

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 […]

NASA’s Perseverance rover discovered “leopard spots” on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.
