Canopus Posted December 20, 2019 Share Posted December 20, 2019 So the Mission timer on the Spacecraft was set wrong. Interesting Problem. Quote Link to comment Share on other sites More sharing options...

tater Posted December 20, 2019 Share Posted December 20, 2019 Plan to land here in NM in ~48 hours. Uncrewed rendezvous and docking not required for a crew flight, but nice to have. Their backup was to send a command, but it was between TDRS, and command didn't get there in time. Quote Link to comment Share on other sites More sharing options...
tater Posted December 20, 2019 Share Posted December 20, 2019 Crew of course could have just done the burn themselves. Quote Link to comment Share on other sites More sharing options...
tater Posted December 20, 2019 Share Posted December 20, 2019 Bridenstine saying two things now. That astronauts might well have simply flown it to station, and that given the situation, the call to "protect White Sands" was correct (protect the ability to do EDL and nominally land at WSMR).

Ultimate Steve Posted December 20, 2019 Share Posted December 20, 2019 Bridenstine just confirmed that going to the spac station is off the table given the fuel levels. Quote Link to comment Share on other sites More sharing options...
sevenperforce Posted December 20, 2019 Share Posted December 20, 2019 Too bad. Shocking that the mission clock is a single failure point. Quote Link to comment Share on other sites More sharing options...

It says something about their ground testing as well that they did not catch it. I presume they have "flown" countless simulations before... it'll be interesting to see what the deal was with this.

Uncrewed rendezvous and docking not required for a crew flight, but nice to have. Their backup was to send a command, but it was between TDRS, and command didn't get there in time. Don't get this, the delta 5 is automated and in control until capsule is released, on release Pe is say 100 km and Ap is at specified orbit, I assume they had already programmed in an circulation burn for the capsule in case of issues with communication or ground control. However as its an chance the launch itself might have issues even stuff like short holds or small inacuracies in the delta burn so want to update capsule burn with better values, I also assume this burn is made so intercepting ISS is cheap. You would start calculating that burn as soon as you are in cruise toward Ap. Not sure if centaur does an second burn here, I almost assume not since capsule does circulation, if so you also want to update it. Granted with GPS on rocket or capsule could do this itself, you still want an human in loop as the rocket would not know that one fail state is to get the capsule into an stable orbit so you can show it can work in orbit and land even if you can not reach ISS. And orbital burns are always automated, or at least you tell the system for too long to burn, on an modern capsule I assume you also tell it to point in one direction manual backup. You can dock manually as an backup, this can also be done remotely. In short I don't understand that went wrong here, was the clock in the capsule control ahead so it burned early?

kerbiloid Posted December 21, 2019 Share Posted December 21, 2019 (edited) Spoiler Was outside of KerbNet visibility, so didn't perform the burn in time. Also maybe they should extend the antennas earlier. Edited December 21, 2019 by kerbiloid Quote Link to comment Share on other sites More sharing options...

Scotius Posted December 21, 2019 Share Posted December 21, 2019 Wonder what the verdict will be... "Yeahhhhh...sure. You don't have to do rendez-vous and docking. We know each other for so long - one out of control spaceship is nothing between old pals *wink wink nudge nudge*" Quote Link to comment Share on other sites More sharing options...
Wjolcz Posted December 22, 2019 Share Posted December 22, 2019 So was rendezvous and docking a part of the submitted certification profile/outline/whetever (I'm really not sure what it should be called)? Because if it was and they didn't do it why should SpaceX commit to their IFA plan then? Quote Link to comment Share on other sites More sharing options...

This flight might prove the vehicle suitable for human flight and then the first manned mission will be used to qualify the rendezvous and docking systems. Assuming the reentry and landing goes to plan and they sort the clock issue out. Quote Link to comment Share on other sites More sharing options...
