NASA’s OSIRIS-REx spacecraft completed its final task for this mission when it released its sample capsule toward Earth less than an hour ago. About 20 minutes after doing so, the spacecraft fired its engines to divert past Earth toward its new mission to asteroid Apophis and was renamed OSIRIS-APEX.

Roughly 1,000 feet wide, Apophis will come within 20,000 miles of Earth – less than one-tenth the distance between Earth and the Moon – in 2029. OSIRIS-APEX is scheduled to enter orbit of Apophis soon after the asteroid’s close approach of Earth to see how the encounter affected the asteroid’s orbit, spin rate, and surface.

NASA’s live coverage of the  OSIRIS-REx  capsule landing starts at 10 a.m. EDT (8 a.m. MDT) on Sunday, Sept. 24, and will air on NASA TV, the NASA app, and the agency’s website.

Daniel Parrott at Siding Spring observatory, Australia managed to observe the separation of the sample return capsule from OSIRIS-REX:

OSIRIS-REx: Now 1 hour to atmospheric entry; the OSIRIS-REx sample return capsule will hit the discernible atmosphere at 10:42am EDT (0242 UTC) at an altitude of 82 miles while traveling at ~27,650 mph; from that point to touchdown at the Utah Test and Training Range: 13 minutes

The #OSIRISREx spacecraft has released the capsule containing a piece of asteroid Bennu. The capsule will plummet through space for four hours, enter the atmosphere over California and land about 13 minutes later in Utah. https://go.nasa.gov/3POfkA2

I got a chance to see the UTTR from the back seat of an F-16 several times including several strafing runs. Interesting views

The SRC has entered the atmosphere and deployed its parachute.

Seemed to be very fast. Did the droque deploy at all? The main did.

RedSky · « **Reply #289 on:** 09/24/2023 03:00 pm »

I was really worried. The IR tracking shot never showed drogue deploy, even after it was past due, and I heard a call that a signal was sent for drogue deploy. Was waiting for another Genesis smash, and was amazed when they showed the main chute out.

Landing time was 10:52 local I think the prediction was 10:55? The drogue is only 31inches in size so maybe it just didn't show up in the video. The main parachute is 24 feet wide.

TOUCHDOWN! The #OSIRISREx sample capsule landed at the Utah Test and Training Range at 10:52am ET (1452 UTC) after a 3.86-billion mile journey. This marks the US's first sample return mission of its kind and will open a time capsule to the beginnings of our solar system.

NASA commentator says the main chute deployed at 20,000 feet, instead of the expected 5,000 feet, and that resulted in the early touchdown. However I think he has that backwards (for whatever reason) and we'll get clarification on that later.

That descent was indeed terrifying, especially when we started seeing the GROUND in the background of the aerial shot. Normally you see the ground in the view only seconds before touchdown, and at the time it wasn't even under chute yet (not visibly, at least). Now of course it's obvious that the aerial shot was from VERY high up. Can't wait for the post-landing presser ...

Maybe they meant "Drogue Chute"? They were saying it had deployed but in the television image it was hard to tell. It looked like the SRC was coming down very quickly for being under any kind of chute.

Nice shots of capsule nose down

landed fairly near some sort of facility as was visible in the helicopter video. https://www.google.com/maps/place/40%C2%B022'18.8%22N+113%C2%B014'23.3%22W/@40.3726451,-113.238996,606m/data=!3m1!1e3!4m4!3m3!8m2!3d40.3719!4d-113.2398?entry=ttu

First Stu Wylie from @usairforce and Vicky Thiem from @LockheedMartin conduct a safety survey of the surrounding area and the #OSIRISREx capsule itself before the rest of the team approaches.
