You like Mars? Of course you do, you wouldn't be following me otherwise (or would you? 😏)
Anyway, here is the treat : a ready-to-follow list of other amazing Martians, only one click away. What are still waiting for? 👇

Awesome imagery captured two days ago by Curiosity, from its location within a trough of the boxwork structure. This is part of a larger, 360° Mastcam panorama.

I think Perseverance may have spotted interstellar comet 3I/Atlas last night from Mars!
After stacking 20 images from Mastcam-Z, I found a faint smudge of light in the constellation Corona Borealis close to the location where the comet was expected. 🔭

A recent vista from Mars obtained by the Perseverance Rover on its 1635th Martian day, or 'Sol', Clouds far above the eternal dust pall are unusually well shown in this afternoon view. This is a mosaic of two wide angle color Navcam images.

I am so happy for Lauren, an MSL team member and Martian planetary geologist! ☺️
I'm absolutely THRILLED to hear my Mars colleague, Dr. Lauren Edgar was selected for the 2025 ASCAN Class. She will be an unbelievable addition to the Astronaut Corps- representing our Mars geology community well- and joining our current Mars geology NASA Astronaut, Dr. Jessica Watkins.

While at CDS, the Aladin project mainly deals with deep sky images, we also map planetary surfaces.
We released the HiPS of China's Tianwen-1 MoRIC images, a true-color map of Mars at 76m resolution.
