sh1pman Posted December 11, 2017 Share Posted December 11, 2017 It’s going to get even more sooty after this one. That’s a few kilos of dead weight every flight. Remember those magnificent CGI videos of shiny BFRs flying around? In reality they are going to be pitch black. Quote Link to comment Share on other sites More sharing options...
Lukaszenko Posted December 11, 2017 Share Posted December 11, 2017 It highlights the fact that it IS used, they are confident that it will fly, and they plan to do it again. Often, quickly, and cheaply. Such that they don't even bother cleaning it. You know when you go check out a used car and it's been so well cleaned that it's suspicious? I think it's kind of like that. Quote Link to comment Share on other sites More sharing options...

cubinator Posted December 12, 2017 Share Posted December 12, 2017 What sort of soot is on the used boosters, and what is needed to clean it off? Why can't they just rinse it off every few flights with, I don't know, a million gallons of soapy water? Quote Link to comment Share on other sites More sharing options...
tater Posted December 12, 2017 Share Posted December 12, 2017 RP-1 soot. Quote Link to comment Share on other sites More sharing options...
Ultimate Steve Posted December 12, 2017 Share Posted December 12, 2017 Stripes! And reused stuff! And CRS-13 on December 13 because that worked so well last time! And a launch time during school. And a school internet filter that blocks YouTube livestreams. Hooray... Quote Link to comment Share on other sites More sharing options...

If this was the upper stage, it would mean a 2-3 kilogram reduction in payload, which wouldn't be a problem for Falcon 9. But on the lower stage, we're talking about maybe a dozen grams of payload reduction, thanks to the rocket equation. Quote Link to comment Share on other sites More sharing options...

DVDRW Posted December 12, 2017 Share Posted December 12, 2017 (edited) What maximum time is allowed between Launch and Static fire? Falcon heavy launch probably in 2019? Crew Dragon ~2022? BFR launch ~2100? Edited December 12, 2017 by DVDRW Quote Link to comment Share on other sites More sharing options...

I have no idea when the image was taken. It was upright yesterday. The delay has to do with the new pad, they are running though everything multiple times, it seems. Perhaps they took her horizontal, then will go vertical again as part of dealing with last minute checks to the new, improved SLC-40.

Might as well burn up the aluminum ones they still have in stock; not like they're going to use them for anything else. Quote Link to comment Share on other sites More sharing options...
