The @NASAMars Sample Return Mission Independent Review Board (IRB) has released their findings and recommendations for the first mission to return samples from Mars. As we establish our response to the report, we are eager for the robust Moon to Mars exploration approach. Mars remains a rich destination for scientific discovery and understanding the Red Planet supports the @NASAArtemis program to ultimately send humans to Mars. nasa.gov/feature/nasa-releas…

Since so many have asked, here’s my hot take on the spherules Loeb found and the manuscript he’s loudly rushed to the world. These are pretty typical cosmic spherules. Had he done the *obvious*--a control sample 100 km away from the meteor--he’d have found the same thing. 1/20

The future astronauts of the @NASAArtemis III mission to the Moon will perform geology tasks designed by a newly-announced team of 12 lunar scientists led by @JHUAPL: go.nasa.gov/45mAI4E The team will plan moonwalk activities including sampling, imagery, and taking measurements.

The rock is reflected in the helmet visor. In the back right is another astronaut taking photographs of the lunar surface. Their helmet lights are on. Credit: NASA

1/3 Our JWST team sees a HUGE plume of water spraying from Saturn's moon Enceladus! Enceladus (Cassini image w/ south-pole jets) fits inside the tiny red box, but EVERY blue point in the JWST image has a corresponding spectrum that shows water! See webbtelescope.org/contents/n… 1/3

We’ve received another incredible photo from the camera onboard our Mission 1 lander! Seen here is the lunar Earthrise during solar eclipse, captured by the lander-mounted camera at an altitude of about 100 km from the lunar surface. (1/2)

PRESS RELEASE: buff.ly/3ZtCmOt For the first time scientists have observed how the debris excavated by an impact into an asteroid disperses into space and how a tail can form from such an event. On Sept. 26, 2022, NASA’s DART crashed a spacecraft into asteroid Dimorphos.

There's snow on Mars. You likely couldn't ski on it, but you might be able to snowshoe. Read more in @TheAtlantic featuring LASP researchers @PlanetaryNoora and @phayne. theatlantic.com/science/arch…

There’s Snow on Mars

And it would be strangely beautiful to behold.

Transport of Water Into the Polar Regions of Mars Through Scavenging by CO2 Snowfall doi.org/10.1029/2022JE007386 Water ice in the atmosphere acts as a seed onto which the CO2 ice condenses, forming CO2 snow clouds. When that snow falls, it removes water from the atmosphere.

To allow @SpaceX to perform additional pre-flight checks of the launch vehicle, we are no longer targeting Dec. 1 for our HAKUTO-R M1 launch. An announcement will be made once a new target launch date is confirmed. #ispace #HAKUTO_R #space #lunarlander #lunarquest

Everyone say hello to my very cheesy paper on my work looking at the water vapour contribution from Swiss cheese terrain at Mars' south pole with @melandisphd @phayne and @ArcticSaxifrage. I think it's pretty gouda 🧀 iopscience.iop.org/article/1…

Two years until the three-week launch period opens for @EuropaClipper - we have made great progress and still have much to do to get ready. Thankfully, we have a fantastic team! #DareMightyThingsTogether #GoEuropaClipper 🚀
