A consolidated Mössbauer spectrum for undisturbed soils from #Gusev Crater, Mars: #Spirit Rover landed on #Mars, ECU's Paulo de Souza has made a remarkable new discovery using data from the historic mission.

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.

How the #Viking1 #Mars landing 50 years ago #OTD was covered on U.S. TV news then: https://www.youtube.com/watch?v=JDiiPhNs2Xw

50 years ago #OTD NASA's #Viking1 landed on #Mars: https://en.wikipedia.org/wiki/Viking_1 - here is part of the first image sent from the surface. The camera was a horizontally rotating scanner moving left to right: the early vertical columns are brighter because dust from touch-down hadn't settled yet.

50 years ago #OTD the #Viking 1 Orbiter with its precious Lander cargo entered into orbit around #Mars: https://www.facebook.com/VikingMarsMission/posts/pfbid034yTJzsyT5ZrNHgsFeNtxrvFDRxRpFQyQfB344patQDdUr7JBCnJZgPBk9sdSuhhNl - the landing came a month later.

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.

Moments ago #Psyche came closest to #Mars during its #GravityAssist - here is the planet yesterday still as a crescent, in fan processing of the raw images https://solarsystem.nasa.gov/psyche-raw-images/ (full caption and credit in ALT).

Spatially distributed complex #organic matter detected in an ancient river valley in #Jezero crater, #Mars: #Raman spectrometer onboard the #Perseverance rover, we report the heterogeneous distribution of organic carbon within mudstones located in an ancient river valley on Mars. Measurements of two mudstones show hundreds of organic detections, making this the most robust organic detection in Jezero crater thus far, and, to our knowledge, the only detection of macromolecular carbon on a natural rock surface on Mars."

Artistic visions shape and respond to #Mars missions: https://www.pnas.org/doi/10.1073/pnas.2622471123 -> "decades before humans might actually travel through interplanetary space, artistic visions continue to help nurture those aspirations."

Hey, #Mars is back in the sky, kind of: during this dawn's #NLC observations - #Pleiades and got it photographically (1 second at f/2.8 and ISO 800) but couldn't see either object naked-eye.

A funny incident just happened on #Mars - the drill of the rover Curiosity got stuck in a rock which was then lifted up and moved around a bit before it fell off on its own: https://www.youtube.com/watch?v=ztB7lgMxr_g
