Welcome everyone!
About OSIRIS-REx
NASA’s OSIRIS-REx, the first U.S. mission to collect a sample from an asteroid, will return to Earth on Sept. 24, 2023, with material from asteroid Bennu. When it arrives, the OSIRIS-REx spacecraft will release the sample capsule for a safe landing in the Utah desert. The pristine material from Bennu – rocks and dust collected from the asteroid’s surface in 2020 – will offer generations of scientists a window into the time when the Sun and planets were forming about 4.5 billion years ago. NASA’s live coverage of the OSIRIS-REx sample capsule landing starts at 10 a.m. EDT (8 a.m. MDT).

As someone not into astronomy much, what are the practical specific questions nasa hopes these samples will help answer?
Is this more knowledge-expanding, general knowledge or is there some specific goal for these samples?
The thing with looking at rocks and stuff on our planet is that we have weather that constantly erodes them and we have a molten core that makes a rock stew that gets spewed out of volcanoes. Asteroids, on the other hand, are sailing around through empty space looking just the way they did when they were formed four and a half billion years ago. So we can learn a lot about the formation of the universe by looking at those rocks that have been frozen in time.
Oh, I see. Thanks, I appreciate it, looking at an artifact frozen in time puts the whole endeavor into perspective for me.
Touchdown!
Parachute deploy!
Any updates yet? Did they find the thing moving inside yet
No aliens, just rocks. End-of-day update:
NASA’s OSIRIS-REx clean room team has finished disassembling the sample capsule and packaging its components, including the unopened sample canister. Now packed in shipping containers – along with the environmental samples the recovery team collected around the capsule’s landing site this morning – the items are scheduled to be delivered on Monday, Sept. 25, to their permanent home at NASA’s Johnson Space Center in Houston.
Helicopter is now transporting the capsule to the clean room.
Sample return capsule has been wheeled into the clean room. Next step is to carefully extract the sample canister from the capsule.
