Le rover Curiosity a brisé une roche en roulant dessus, dévoilant des cristaux clairs et laiteux. La zone étant riche en sulfates, il est très probable que ce soit des cristaux de gypse, parmi les plus beaux que je vois depuis le début de la mission ! 1/3
#PPOD: This scene is a mosaic of two Right Mastcam-Z camera images taken by NASA's Perseverance rover on 27 May 2024 at a local time of 3:15 pm. The color approximates natural human vision. Most boulders are largely basaltic, with evidence of being rounded by wind. We can't wait to learn the composition of the lighter-toned one in the middle of the scene, though, as it appears to be something different. Credit: NASA/JPL-Caltech/ASU/Paul Byrne
Martian meteorites are turning out to be quite an asset. These tiny bits of rock were chipped off of Mars, flung into space, and eventually landed on Earth about 11 million years ago. Today they’re giving scientists new insight into the fine structure of the outer later of the red planet. Science Alert explains: https://flip.it/Lb8hDb #Science#Mars#Earth#Meteorites
Zooming in on a peculiar white rock in Neretva Vallis
This is a combination of three SuperCam RMI images and one Mastcam-Z image taken by the #Perseverance mars rover.
The images were taken two days ago on Sol 1164.
#PPOD: Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude. The crater is 81.4 kilometers in diameter and contains about 2,200 cubic kilometers of water ice, comparable in volume to Great Bear Lake in northern Canada.
