Ground penetrating radar observations of ancient large-scale deltaic structures in Jezero crater, #Mars: https://www.science.org/doi/10.1126/sciadv.adz6095 -> Perseverance’s radar revealed ancient subsurface river delta on Mars: https://arstechnica.com/science/2026/03/perseverances-radar-revealed-ancient-subsurface-river-delta-on-mars/ - there may be a river delta hidden under the obvious delta in a Martian crater.

It might not yet have reached Earth orbit, but #RelativitySpace has announced plans for a mission to #Mars carrying a NASA payload: #Aeolus and scheduled for 2028, will launch a Mars orbiter carrying four NASA-built instruments.

More #Psyche images of #Mars, now with NASA's own processing (but further improved in contrast here) from #GravityAssist went well: with the ion engine on again the spacecraft should reach the asteroid Psyche in August 2029.

Why Mars astronauts need more than just space greenhouses
Thinking about food systems in deep space likely brings to mind something like The Martian where an astronaut is scratching barely enough food to survive out of potatoes grown in Martian regolith. Or perhaps a fancy hydroponic system on an interplanetary transport ship, with artificial lighting and all the associated technological wizardry. But a new paper published in Acta Astronautica by Tor Blomqvist and Ralph Fritsche points out that growing food is only one small part of the whole cycle of…

Yay, the #Mars close-up images taken by the #Psyche spacecraft during its #GravityAssist two days ago have begun to appear on https://solarsystem.nasa.gov/psyche-raw-images/ - severe image processing required ...

Meanwhile some Slope Streaks in Amazonis Planitia on #Mars from the MRO: https://www.uahirise.org/hipod/ESP_076980_2115 - a paper had proposed this location as a candidate site for recurring slope lineae (RSL), where slope streaks were also observed.

And another #Psyche #Mars image from the #GravityAssist, just in as https://solarsystem.nasa.gov/psyche_images/6658/ - see also https://bsky.app/profile/thomasappere.bsky.social/post/3mm2lwu6qrk23 for a great mosaic from images appearing previously on https://solarsystem.nasa.gov/psyche-raw-images/

Two more #Psyche pictures from the #Mars #GravityAssist two days ago - https://solarsystem.nasa.gov/psyche-raw-images/ is taking off, but a lot of contrast-boosting remains necessary.

Almost like the real thing: Three years before ESA's #ExoMars rover #RosalindFranklin is scheduled to land on #Mars,
