Although they were showing an empty barge for so long after the ticker said it should have landed that I thought they lost the booster. Was happy to see it magically sitting there. Hide contents So we have the hosers Bob and Doug in space now. Apparently (according to a post somewhere my wife read) the Aviation Analyst covering the launch for CNN is named Miles O'Brien. Name seem familiar? Chief engineering Officer on NCC 1701-D! Yep, I was worried too. We haven't seen loss of signal from the droneship in a while. I strongly suspect that they intentionally planned to cut the feed at landing to avoid broadcasting an exploding booster while Bob and Doug were still strapped to F9US.

Probably; I was mostly paying attention to the gauges. Once the numbers stopped changing so quickly, my KSP experience told me that those guys were in a stable orbit. Someone on Imgur commented on my album and asked "Can you imagine 19 hours without toilet breaks?" Quote Link to comment Share on other sites More sharing options...

We've already seen American astronauts say that Soyuz is smoother than the Shuttle because the SRBs were so shaky. I am certain F9 is even smoother than Soyuz. The gee-loading is different, too. I believe that with the Shuttle the SRBs had a lower burnout TWR than the SSMEs; here the first-stage burnout TWR is higher. Quote Link to comment Share on other sites More sharing options...

Do they have plans to stuff it a bit more, or to shorten the trunk or something ? Is this the default rendezvous maneuver procedure, or is there a shorter or longer one ? Dragon trunk is not carrying any comanifested cargo today because it is the first crewed test flight. I am sure they will begin comanifesting unpressed cargo as needed during operational missions. Rendezvous varies a bit depending on launch window. Quote Link to comment Share on other sites More sharing options...

KSK Posted May 30, 2020 Share Posted May 30, 2020 Oh man - that was awesome! That's how its done - and that's a real modern-day spacecraft they've got there. Got chills listening to the abort mode callouts and that over-the-astronaut's-shoulder view was... it just was. Quote Link to comment Share on other sites More sharing options...
Delay Posted May 30, 2020 Share Posted May 30, 2020 Hang on, they're using the Dracos for orbital maneuvering, right? The Superdracos are only for LES, yes? Quote Link to comment Share on other sites More sharing options...
sevenperforce Posted May 30, 2020 Share Posted May 30, 2020 Our half-centaur-in-chief got to watch it live and in person from a rooftop. I am jealous. He doesn't know the front end of the rocket from the back end. Quote Link to comment Share on other sites More sharing options...

In fact the very last abort mode before abort-to-orbit would have called for separation and firing of the nosecone Dracos to hit the Ireland coast.

You know, I wonder how "Are you currently playing, or have you ever played, Kerbal Space Program?" as a job interview question for NASA/SpaceX would affect the kind of employees those companies would get. Would the company do better or worse if they got KSP veterans (as well as qualified individuals)?

The Orion space toilet would fit on Crew Dragon with room to spare. Does anyone know if they doff the suits en route to the ISS? Also have we heard what they named the capsule?

Interesting that they did a burn rather than a propulsive vent. I guess they reserved hella margins for this mission. I wonder who decided to do a single-engine landing burn. Reserving extra props for a single-engine burn means a lower staging velocity, which means lower S2 residuals. Probably like an 0.0000001% greater chance of LOCV in exchange for a better shot at a norminal landing. Quote Link to comment Share on other sites More sharing options...

Delay Posted May 30, 2020 Share Posted May 30, 2020 What was this temperature outlier about? Before the phase burn started, they said they had an out-of-family temperature reading. It didn't pose a threat to the mission, but they'd look into it. Quote Link to comment Share on other sites More sharing options...

Maybe they consider the vent a burn in this particular situation? Quote Link to comment Share on other sites More sharing options...
