IonStorm Posted September 21, 2023 Share Posted September 21, 2023 (edited) The burn on 8/17/23 was a ∆V of 3 mm/s. (Not even the smallest burn in OSIRIS-REx history. There was a burn to adjust the phasing of the orbit around Bennu of 0.1 mm/s It is described in the latest blog https://blogs.nasa.gov/osiris-rex/2023/09/19/osiris-rex-makes-final-course-adjustment-before-sept-24-sample-delivery/ (I wrote the one on May 23 about science https://blogs.nasa.gov/osiris-rex/2023/05/23/guest-blog-bennu-and-some-of-the-biggest-science-questions-of-our-generation/).

Gargamel Posted September 22, 2023 Share Posted September 22, 2023 IIRC there was some issue getting the sample container to close correctly? Is there any lingering issues with this? Quote Link to comment Share on other sites More sharing options...

Is there any lingering issues with this? There are two different things. The sample collection device (TAGSAM) was overflowing with sample. So material was leaking into space since the mylar flap was wedged open with rocks. We stowed it quickly to prevent losing more. Still, we collected 250±101g from our 60g requirement. https://www.asteroidmission.org/wp-content/uploads/2020/10/5_deg_fast_cropped-3-frame-slowed86.gif We stowed the sample head and checked that it was locked in place. https://www.asteroidmission.org/wp-content/uploads/2020/10/src_stow_head.png Then closed the sample return capsule (SRC) lid. https://www.asteroidmission.org/wp-content/uploads/2020/10/StowCam_SRC-Close-Gif.gif No lingering issue.

Remarkable & inspiring to me that a collection of very capable & dedicated humans have the skills & team work to design & build & navigate a machine to a tiny aggregate pile, where even solar radiation/particles observably alters orbits, effectively put a 'mosquito' in orbit around a 1 ton sphere (ok I get that probably means nothing to anyone else but is was a running joke my peers & I had in one physics class eons ago...), adapt to challenges, collect a sample, & send that sample on a collision course with Earth...due for arrival in Utah in about 40 hours...

HebaruSan Posted September 24, 2023 Share Posted September 24, 2023 The on-scene air force commander said it's planned to land in a weapons testing area that might have hazards like unexploded ordinance. I'm sure it'll be fine, but it sounded surprisingly dangerous for an object whose integrity they want to ensure. It must be hard to find an uninhabited area with plenty of helicopters.

Minmus Taster Posted September 24, 2023 Share Posted September 24, 2023 I had a pretty strange dream, I saw the parachute on the capsule failing and the sample plummeting to the ground. Of course I then saw it crashing into a city and maybe also smacking Air Force 1 out of the sky? This is why I don't believe in dreams but you never know Quote Link to comment Share on other sites More sharing options...

That doesn't add up to me. A higher parachute deployment should result in a longer descent. Perhaps they mean the parachute deployed at 5000 ft at the time when they expected it to still be at 20000 ft? Without telemetry I can't say.

That seems odd I didn't catch the exact name of the source and don't want to rewind and miss the present, but it was from one of the teams communicating with the live stream commentators. Possibly the ones that were going to study the re-entry trajectory. Harmless operational surprises have been the rule on this mission. The rubble being looser than expected, the sample container overflowing. First helicoper now on site. 6 minutes ago, cubinator said: That doesn't add up to me.

Well, the live stream announcer just repeated it. I'm not sure how to get further confirmation; hard to imagine a news article covering it after this. Presumably 20000 ft was significantly earlier in the trajectory, so maybe we lost 5 minutes of coasting and gained 2 minutes of chute (for example)? On scene commander and one other walking over for safety check. Quote Link to comment Share on other sites More sharing options...
