Just released: NEW images of Phobos over Mars by @esa.int Mars Express 🔭🧪

This view shows Phobos above Olympus Mons!

Captured on May 14, 2025 | Image ID: HQ967
Raw data from: psa.esa.int

A high-resolution color image of Mars with the small, dark, potato shaped satellite Phobos, seen in sharp contrast as it passes over the massive volcano Olympus Mons. Phobos appears irregular and shadowed against the softly rust colored Martian surface. In the distance, two other volcanic features Ascraeus Mons (upper right) and the flatter Alba Mons (upper left) are visible. Wisps of light clouds and the blackness of space frame the planet’s curved horizon.

Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar #comet 3I/Atlas flying by the red planet.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

Today some of NASA's Mars fleet is observing Comet 3I/Atlas. This is something their instruments aren't really designed to do, but fingers crossed some useful data comes down. (Won't be able to post anything until after the shutdown.) Simulated view in "Eyes on the Solar System" go.nasa.gov/4goaV2t

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. 🔭

image of the night sky showing a starfield with several dark and bright stars that are quite elongated due to the long exposure time.

the stars of the constellation corona borealis are annotated in green. a faint smudge, perhaps comet 3I/Atlas is marked with a red circle.

This photo from the Perseverance rover captured in early March, may be my favorite Mars image from this year.

It shows Mars' smaller moon Deimos over the hills of the Nili Planum region in the dark skies before dawn. 🔭

A picture of Mars taken during astronomical twilight (the sun was 13° below the horizon). It shows a dimly lit reddish landscape with some hills at the horizon. Deimos, Mars' smaller moon shines with a small halo in the pale sky above.

Vous cherchez un spot pour faire de l'escalade 🧗‍♂️?
J'ai ce qu'il vous faut : admirez ces superbes falaises sur Mars photographiées par le rover Curiosity. Celle au centre fait ~39m de haut et avec la faible gravité martienne (1/3 de la pesanteur terrestre), il sera plus facile de grimper !

Last night, NASA's Perseverance rover attempted to photograph the interstellar comet 3I/Atlas from the surface of Mars.

A first look at the image sequence shows some stars in the constellation Hercules where 3I/Atlas is currently located. 🔭

I finally decided to tackle an issue with the Perseverance Navigation camera images which show some strange artefacts when the sun overexposes the sensor.

The highlight recovery is done through gradient estimation, inpainting and channel ratio tricks to restore the color of the overexposed areas.

Afternoon image from Perseverance showing the sun low in the sky. The landscape is mostly dark because of the short exposure.
The sun is overexposed and has a weird dark purple ring on it that is probably caused by the correlated double sampling applied by the camera.

The same Afternoon image from Perseverance showing the sun low in the sky. However, the overexposed area of the sun is now considerably smaller and the weird color fringe is gone, giving a much more natural appreance.

Star trail images made with time-lapse sequences photographed by astronauts from ISS Expedition 67.

Each sequence was restored, remastered & retimed using frame interpolation for a 35m15s film called 'Space Night'.
