A space spookfest

Escape of the asteroid samples! NASA’s OSIRIS-REx mission collected a lot materials from asteroid Bennu final week that the pattern head’s Mylar flap couldn’t absolutely shut, permitting rocks and dirt to drift out into space (pictured). The mission staff determined to stow the pattern as shortly as attainable, and that process went easily. The pattern of Bennu is now safely saved and prepared for its journey to Earth in March 2021. Hear extra in regards to the mission on this week’s Planetary Radio with visitor Dante Lauretta, principal investigator for OSIRIS-REx.

Other scientists utilizing completely different methods to course of the unique knowledge haven’t been capable of finding it, both.A world gone rogue! Scientists have introduced the invention of what will be the smallest-ever rogue planet. Rogue planets start their lives round different stars earlier than gravitational interactions with different worlds or stars fling them into interstellar space. Because rogue planets don’t mirror close by starlight, they’re normally discovered utilizing a way referred to as microlensing, the place the gravity of a planet briefly magnifies the sunshine from a background star.
Howling on the water on the Moon! NASA’s flying SOFIA observatory, which The Planetary Society toured in 2016, has detected water in sunlit areas of the Moon’s floor. The findings might assist scientists be taught extra about the place Earth’s water got here from and the way the Moon shaped. If you need to mine Moon water, the completely shadowed craters close to the poles are nonetheless your greatest guess; sunlit lunar soil remains to be 100 occasions drier than the Sahara Desert.
