Brotoro Posted July 27, 2023 Share Posted July 27, 2023 Seems to be more of those lately. I wonder if they have tightened up the windows for acceptable data values. Quote Link to comment Share on other sites More sharing options...

AckSed Posted July 27, 2023 Share Posted July 27, 2023 Aiya. Though a SpaceX launch may be normal, it's never routine to the people in charge of it. Quote Link to comment Share on other sites More sharing options...

The scrub before this one for instance Quote Link to comment Share on other sites More sharing options...

Why do you immediately assume it is an issue with the reuse feature, without finding out what happened? Quote Link to comment Share on other sites More sharing options...
RCgothic Posted July 27, 2023 Share Posted July 27, 2023 3 cores, three times the number of sensor limits that could be violated. I also think talk of reusability limits being violated is premature. Also, the centre core is never before flown and the side boosters have flown twice. This falcon heavy is a rookie by falcon standards. It could be they've recently encountered a new fleet issue that they're currently keeping an enhanced eye on, or it may be a higher number of scrubs right now is just dumb luck.

AckSed Posted July 27, 2023 Share Posted July 27, 2023 (edited) Side note: Remember the cut-down nozzle on the Merlin Vacuum on some of the second stages? 8 minutes in, the announcer dropped the fact that there are three 2nd stage configurations: standard, medium and long coast, depending on how long it needs to operate after launch. If the short Mvac is related to those, is the cut-down the new Standard? Edited July 27, 2023 by AckSed Quote Link to comment Share on other sites More sharing options...

If the short Mvac is related to those, is the cut-down the new Standard? Nozzle size impacts efficiency but it wouldn't be particularly meaningful for operation duration. The longer-coasting upper stages have the grey solar-thermal band around the kerosene tank to prevent freezing, plus extra COPVs to support ullage repress and more engine restarts. I'm guessing long-coast simply has more extra COPVs than medium-coast. Quote Link to comment Share on other sites More sharing options...
RCgothic Posted July 27, 2023 Share Posted July 27, 2023 (edited) I'm not sure. Length of coast isn't necessarily related to DV performance, though certainly higher energy manoeuvres such as GEO insertion or LO insertion requires longer coasts so there is some correlation. But if you burn immediately for a high energy earth departure then you'll need a regular nozzle but won't need endurance mods. It could make sense that Standard is the new half-cut MVac, Medium is Falcon Upper Stage Classic, and Long Coast is upper stage with endurance mods. Alternatively Standard could be the regular upper stage, Medium is with the usual long-coast mods, and Long-Coast is a new ultra-long coast spec for lunar missions and such, with short MVacs an option on all of them. I'm speculating. Definitely interested to find out more. Edited July 27, 2023 by RCgothic Quote Link to comment Share on other sites More sharing options...
