SpaceX F9 : Crew Dragon In-Flight Abort Test : Jan. 19, 2020 : Discussion

Also - I know they said no FTS on this, but boy that sure looked like they unzipped it... Pretty spectacular! Humbling regardless to think of humans riding that much energy.


And comforting to see how they would have been able to get away! The Dragon really had some giddy-up.

The announcers seemed to anticipate the drogue deployment for a long time, discussing a "drogue deployment window" or somesuch.  Perhaps that timing could explain the shorter time to splashdown than expected.

I wonder which part of F9 survived... The object falling that was shown in Everyday Astronaut stream seemed to be an intact part of F9 that exploded on impact when it hit the water at terminal velocity.

Logically one would assume that the aerodynamic forces would rip apart the larger part (stage 1) and that is what we saw blow up and fully intact, fully fueled second stage is what hit the water.

But I guess I could see a scenario where interstage "airscoop" caused the second stage to rupture and caused that fireball while first stage just barreled through all that and eventually hit the water.

Something probably worth asking at the post-launch presser maybe?

My money's on that.

I thought this when I watched it live, then went back and watched it again and still think the same thing...

I'm not convinced that the main chutes fully unreefed. Visually it didn't look like they fully opened, the capsule landed ahead of anticipated time, and Jon said the they would go to reef position 3 and I only saw two unreefing events, not three.

I'm solo certified in skydiving so at least have a small inkling of what to look for.

I hope I'm wrong. Probably am.

Looking back at stream and all looked nominal from my untrained eyes on the 4 chute configurations deployment.  See 24 min in stream - you can seem them slowly unfurling to full deployment. 

Good stuff!

Is it my imagination or are the 2 seats different? White and black w/armrest  on the left. All black w/ no separate arm rest on right. Possible that they are row 1 and row 2 seats?

[winkhomewinkhome]

I find it curious that the "Dragon Specs" still noted the crew capacity as 7 people (?), thought it had be modified (at NASA's direction) to four due to constraints created by seat angle modifications...

Wow, John Kraus got a photo of the part that hit the water.

Looks like S2+Interstage.

Yeah and rewatching the SpaceX webcast, John Insprucker confirmed the loss of telemetry on 1st stage.

I think someone said awhile back that the second stage would be unfueled

Fully fueled, regular S2 just no MVac engine.

Well, I'll accept the accusation of jumping the gun and just say: "Dragon, you are go for orbit!"

"Test like you fly". It was missing a proper MVac engine, carried a mass simulator instead.

I recall hearing fueling callouts on the net prior to launch which mentioned the second stage.  I believe it had propellant.

Also frosting visible on the SpaceX youtube stream. The stage was fueled.
