OSIRIS-REx Asteroid Sample Return [video]
- placesalt 3y agoPretty exciting stuff, showing a live image of the capsule entering right now Edit: Neat seeing EDL from an earth POV, too. Kind of reverses the usual formula for eg landing on Mars. Edit edit: touchdown!

- qingcharles 3y agoGreat live images on this all the way from the point it hit the atmosphere!
- Symmetry 3y agoFor a moment I was afraid the drogue shoot had failed to deploy. But congrats to NASA for getting an asteroid sample safely back to Earth!
- oittaa 3y agoI saw people speculating that maybe the drogue failed to deploy and that's why it landed 3 minutes earlier than predicted. https://twitter.com/DJSnM/status/1705958092842615042 https://twitter.com/DJSnM/status/1705958092842615042
- dotnet00 3y agoThere are also reports the main chute deployed much earlier, which doesn't seem like it'd fit with the early landing https://twitter.com/cbs_spacenews/status/1705961833893400593 https://twitter.com/cbs_spacenews/status/1705961833893400593
- placesalt 3y agoThey said during the broadcast that it deployed at 20kft instead of the planned 5kft. But GGP is correct, it really did look for a little while there like it maybe hadn't deployed on time.
- abracadaniel 3y agoIt certainly looked that way from the stream, but the drogue chutes can be on much longer tethers, so maybe it was out of frame? If they were able to do it without the drogue, that’s pretty impressive.
- didgeoridoo 3y agoPerhaps the coolest thing to me about this mission is that they pulled off this historic sample return, and then the craft swung back around to head out for another mission. This would be really fun to try in KSP.
- Tuna-Fish 3y agoI wish it had an another sample return capsule, but at least it's going to get to poke Apophis with a stick and record the spectrum of what is thrown off.
- dotnet00 3y agoIt's worth remembering that being able to head back out is itself a bonus. It just so happened that another asteroid happened to be in the right place for the spacecraft to get to.
- throw0101a 3y agoIn the top-left corner there is a counter with "OSIRIX-REx Landing \n G+x". Never heard of "G+" time before.
- dmix 3y agoIt's pretty amazing they launched it to an asteroid, landed something on it, brought it back up, then flew it back to earth and managed to drop it within a specific small zone of the Utah desert. And then on top of that the spacecraft is going to continue on studying another asteroid. I guess they figured out a lot of this stuff with the first moon rock samples in 1969 but still it's amazing thinking about all the moving parts. They also apparently learned a lot from the failed solar wind sample return called Genesis. https://en.wikipedia.org/wiki/Sample-return_mission https://en.wikipedia.org/wiki/Sample-return_mission
- neilv 3y agoSometimes I imagine that we're all some superbeing's figurative ant farm, and that it's delighting them when we collaborate to understand the nature of our space and physics. Maybe this partly redeems us, from all the times they're tempted to discard us, and disinfect the ant farm enclosure with bleach.

- eh_why_not 3y agoBeautiful! I was reading that there have been sample returns from asteroids before, like Hayabusa (by JAXA) in 2010. It's said that asteroid sample returns could shed light on the early days of our solar system. Anyone know what kind of new insights they were able to derive from those samples in the past 13 years?
- echelon 3y agohttps://en.wikipedia.org/wiki/Sample-return_mission https://en.wikipedia.org/wiki/Sample-return_mission Check out the article for each mission for a high level summary of at least some of the findings.
- eh_why_not 3y agoUnfortunately there isn't much in those pages (hence the question) [0], and the journal articles referenced are paywalled [1]. Seems the main result was a suggestion (confirmation, maybe?) that meteorites came from asteroids. Was wondering if anyone here has some deeper/hands-on knowledge of this stuff.

- ianai 3y agoRead a headline indicating this asteroid might impact earth one day.
- gremlinsinc 3y ago> Sir Brian May, of Queen, has told Nasa TV he is “immensely proud” to be a team member of Osiris-Rex. May was among those who helped to identify the location on Bennu where the samples would be collected. Can you say overachiever? I mean best rock band ever and still doing astrophysicist work? Seriously though I'm in awe someone can accomplish so much, I often feel I can barely keep everything afloat.
