The search for ice on the Moon features prominently in NASA's plans for Artemis, and the results of the search may define the near future of human spaceflight beyond low Earth orbit. theconversation.com/scientis…

Scientists suspect there’s ice hiding on the Moon, and a host of missions from the US and beyond...

Some dark craters on the Moon are never exposed to light − ice could be hiding in these permanently shadowed regions, and India’s Chandrayaan-3 mission marked a big step toward finding it.

En route to the AAS/DPS meeting (with EPSC this year) where I'll be sharing some hot-off-the-presses research on Europa's surface composition and interactions with Jupiter's magnetosphere! Looking forward to seeing what everyone else is up to

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

Some of the first data coming down from India's @isro Vikram lander show the extreme thermal gradient in the top few centimeters of the lunar soil. Colder temperatures are expected beneath the surface during local daytime. Ice would be stable at -160 C.

Chandrayaan-3 Mission: Here are the first observations from the ChaSTE payload onboard Vikram Lander. ChaSTE (Chandra's Surface Thermophysical Experiment) measures the temperature profile of the lunar topsoil around the pole, to understand the thermal behaviour of the moon's surface. It has a temperature probe equipped with a controlled penetration mechanism capable of reaching a depth of 10 cm beneath the surface. The probe is fitted with 10 individual temperature sensors. The presented graph illustrates the temperature variations of the lunar surface/near-surface at various depths, as recorded during the probe's penetration. This is the first such profile for the lunar south pole. Detailed observations are underway. The payload is developed by a team led by the Space Physics Laboratory (SPL), VSSC vssc.gov.in/spl.htmlin collaboration with PRL, Ahmedabad prl.res.in/prl-eng/

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.

Our new paper, led by recent CU graduate Dr. Andrew Wilcoski, investigates the possibility of ice in caves on the Moon. We find that they make poor cold traps compared to craters at similar latitudes.

Thermal Environments and Volatile Stability Within Lunar Pits and Caves doi.org/10.1029/2023JE007758 High-latitude pits make poor cold traps for ice because they lose heat inefficiently and become warmer than craters at similar latitudes.

This is devastating news. An Yin was a bright light on the faculty at UCLA, mentor to some of my best grad-school friends, who adored him. At conferences I enjoyed discussing his "crazy ideas" about Mars tectonics, always presented with earnest good humor. He'll be missed dearly

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.
