tater Posted July 1, 2020 Author Share Posted July 1, 2020 Of course in February they said they were delivering 2 engines to ULA in May. It;s now July, and that picture is 1 engine (I assume if they had 2, they'd take a picture of 2). Quote Link to comment Share on other sites More sharing options...

XB-70A Posted July 18, 2020 Share Posted July 18, 2020 Turns out Parker Solar Probe (nor Solar Orbiter) doesn't have a dedicated thread, so I will leave those beautiful pictures here, on the launch provider's topic. Quote Link to comment Share on other sites More sharing options...
RCgothic Posted July 21, 2020 Share Posted July 21, 2020 Vulcan Heavy Heavy spotted: And a few words on upper stage endurance: Quote Link to comment Share on other sites More sharing options...
tater Posted July 21, 2020 Author Share Posted July 21, 2020 A Vulcan Heavy done that way has SLS Block 1 throw to TLI (more, actually, about 30t) if the relative performance of F9e vs FHe is any sort of benchmark. Quote Link to comment Share on other sites More sharing options...
RCgothic Posted July 21, 2020 Share Posted July 21, 2020 It's a difficult equation. Without SRBs Vulcan's payload is much reduced and I'm not sure the core stage can withstand side cores plus SRBs. The absolute limit, assuming Centaur Heavy gets to orbit basically full and has a similar dry mass ratio to Centaur III is ~64t to TLI. That's frankly incredible, and isn't that unreasonable given the sustainer architecture. It probably can't take off with that much payload, but there's some seriously impressive EOR missions to be had with an upper stage that powerful...

Yes only weird thing that their attitude during stream at the time around the start of injection burn was up to 5 km below Pe. Have fun trying to do that in KSP Looked a bit weird as the values kept updating. Quote Link to comment Share on other sites More sharing options...
