Nathan Hubbard<p>Live stream of the Barnard-Seyfert Astronomical Society meeting. Tonight we’re excited to hear from NASA astrobiologist Dr. Jason Dworkin as he shares insights from the OSIRIS-REx mission, which returned over 120 grams of asteroid Bennu to Earth—revealing clues about the early solar system and recently published in Nature Astronomy! 🚀🌍 <a href="https://macaw.social/tags/OSIRISREx" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OSIRISREx</span></a> <a href="https://macaw.social/tags/Astrobiology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Astrobiology</span></a> <a href="https://www.youtube.com/watch?v=XpuVuPqnDLI" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=XpuVuPqnDL</span><span class="invisible">I</span></a> <a href="https://macaw.social/tags/space" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>space</span></a></p>

OSIRIS-REx Failed to Deploy its Drogue Chute Properly. Now NASA has Figured out Why

Universe Today · OSIRIS-REx Failed to Deploy its Drogue Chute Properly. Now NASA has Figured out WhyOn September 24, 2023, NASA’s OSIRIS-REx mission returned a precious sample of rocky material from asteroid Bennu to Earth. The capsule landed safely under its main parachute, but it arrived more than a minute early. The cause: a small drogue parachute, designed to slow the spacecraft down prior to the main chute’s deployment, failed to … Continue reading "OSIRIS-REx Failed to Deploy its Drogue Chute Properly.

When the OSIRIS-REx sample return capsule landed successfully on Sep 24, NASA had reported that the parachute system did not deploy properly. NASA offered an explanation today that the sequence of operations to deploy and to cut free the drogue parachute were executed in reverse order!

The diagram below describes what transpired.

Root cause: Incorrect wiring due to mislabeling in schematic.

There had been a severe parachute anomaly during the return of the #OSIRISREx sample capsule - the touchdown speed was acceptable nonetheless and no damage done, but in blogs.nasa.gov/osiris-rex/2023 NASA finally explains what went wrong. And it is pretty embarrassing ...

TONIGHT (11/28) at 12:30 UTC/21:30 JST it'll be the LAST AND GREATEST public seminar on sample return missions.

And... I will be chairing 🪑, asking BLISTERING QUESTIONS to our panel, who include NASA & JAXA people working on the curation of grains from Apollo, #OSIRISREx, #Hayabusa2 and the upcoming #MMX mission, and the Smithsonian Museum who grabbed a grain from asteroid Bennu to display.
