Description
Cosmic Coffee Time’s resident space rock expert and NASA mission scientist Greg Brennecka is back again to preview the return to Earth of NASA’s incredible OSIRIS-REx mission. OSIRIS-REx is coming to the end of an epic seven year journey to collect a rock and soil sample from asteroid Bennu. Greg is a mission scientist on OSIRIS-REx and will be doing analysis on the Bennu sample in his own lab. It’s breathtakingly rare to get a pristine sample from an asteroid in another part of the solar system, and Greg shares with us the plans for this sample and what this 60 gram sample of asteroid could teach us.  If you want to learn more about rocks from space, check out Greg's book 'Impact' at Harper Collins here     Follow Cosmic Coffee Time on Twitter for some special content   twitter.com/CosmicCoffTime   You can request a topic for the show!
