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
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.

Here is a 360° panorama captured by Curiosity at her current location, with North at center and South at both ends, on top of two large and small scale maps with her position.
There are many geological features in the panorama, can you find them in the maps?
#PPOD: This stunning photo was taken by the High Resolution Stereo Camera (HRSC) onboard the ESA's Mars Express spacecraft. Phobos is the larger and closer of Mars's two moons, the other being Deimos. One hypothesis of their origin involves the possible capture of primitive asteroids. Unfortunately, Phobos is being pulled apart and closer by Mars's tidal forces and gravity. Credit: ESA/DLR/FUBerlin/ @andrealuck CC BY (https://www.flickr.com/photos/192271236@N03/53635851891/)
Remember the X8.7 solar flare on May 14, as sunspot region 3664 was rotating away from earth?
The #CME from that flare reached Mars on May 19. Mars rover Curiosity took some nighttime images of the Martian sky hoping to catch an #aurora.
#Mars lacks a global magnetic field, hence Martian aurorae are not concentrated at the poles, but instead appear as a “global diffuse aurora” associated with Mars’ ancient, magnetized crust.
"#SpaceX satellites threaten to hide asteroids that pose danger to humanity
The International Astronomical Union demands that urgent action be taken against the uncontrolled proliferation of these devices. #Starlink satellites make it difficult to search for objects at risk of impacting the Earth"
