ULA won 60% of the launches with SpaceX winning the remaining 40%, beating out Northrop Grumman and Jeff Bezos’ Blue Origin. Quote Link to comment Share on other sites More sharing options...
RCgothic Posted August 7, 2020 Share Posted August 7, 2020 (edited) ULA have phenomenal injection accuracy! It's definitely a unique selling point that justifies a slightly higher cost. I'd like to see what SpaceX's comparable charts look like! Edited August 8, 2020 by RCgothic Quote Link to comment Share on other sites More sharing options...

Yeah, I have to say while my current first choice to fly out and view a launch would be FH with RTLS side booster landings (because visible booster landings), DIVH is second, what a beast.

True, yes they had some very long RCS burns on that mission, but then on target monoprop is dead weight anyway outside of rotating you.

RCgothic Posted August 19, 2020 Share Posted August 19, 2020 Interesting! So basically it's not that the main burn is exceptionally accurate, but they spare nothing on vernier RCS burns! Quote Link to comment Share on other sites More sharing options...

Yes done missions like that in KSP, you have docked with the lander Moho lander so I just need an tiny bit of RCS so burn it asap, however I waited until burn point to do it but guess they have a bit better software than mechjeb And if you get an second stage problem this could save your mission.

Ultimate Steve Posted August 27, 2020 Share Posted August 27, 2020 Well I have work to do anyway and I had a nap earlier, might as well stay up for this I guess... DIVH is temperamental though so there will probably be more setbacks. Quote Link to comment Share on other sites More sharing options...

mikegarrison Posted August 27, 2020 Share Posted August 27, 2020 (edited) At least scrubbing is clean, right? (How did that word get associated with "we will not do this thing today" anyway?) Edited August 27, 2020 by mikegarrison Quote Link to comment Share on other sites More sharing options...

(How did that word get associated with "we will not do this thing today" anyway?) Good question... First known use 1828: Quote “If I were alone, I could scrub it [a visit to London], but there is no doing that with Anne” (a diary entry written March 22, 1828, and first published in The Journal of Sir Walter Scott, 1941). It was in full use WRT missions during the war (ww2). Really is hard to figure out where it came into the use meaning cancel though. Erasing a blackboard?
