It includes a few extra images that were lagging behind, completing the picture of the rim of Jezero Crater behind the rover.

Bridging the 1970s: Lunar Viking (1970) The story of spaceflight told through missions and programs that did not happen - that is, the great majority of them.

I have a question for all you Mars rover aficionados - could the Curiosity and Perseverance rovers operate on the Moon?

This study I wrote about assumed that the Viking Mars lander could be used at the Moon, which got me to thinking.

Thanks for sharing! Since this week the same images can be viewed also on Android phones with the free areoHDR app, the same app as is already available since a year for iPhone.

Nebulous blue gas surrounded by red gas against a sea of stars. Looks a bit like a galactic flower.

The ancient remains of Abell 31, a planetary nebula that is dissolving back into the Milky Way as its central star nears the white dwarf stage.

@mapperwocky.bsky.social do you know if Percy is at Lac de Charmes now? From the location pinpointed in the map below, I would say that Percy is ~ 200 meters NNW of it. Thanks! D.

Fascinating: selfie with mast head looking down, and also capturing, to the left of the mosaic, a shadow selfie of the instrumented turret at the end of the robotic arm, from where the selfie is taken, by the SHERLOC WATSON camera... #Mars 🧪🔭

A mosaic of images captured by the SHERLOC WATSON camera located on the instrumented turret mounted on the Perseverance rover's robotic arm. The cameras on the mast head look straight at us. Rover tracks are seen in the background.

Totally awesome new selfie captured by Percy, with the rim of Jezero Crater at her back, and her latest abrasion patches on the rock to the left.
