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 data from the #Mars flyby by the #Psyche spacecraft in May have been received: #asteroid Psyche in 2029.

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.

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."
