You know a whole the size of a quarter can wreck the entire spacecraft and make it effectively throw away? Also, you'd want to use this many times. Making a system robust while not requiring months of refurbishment is really really hard.
- ceejayoz 5mo agoThe Space Shuttle had that problem because it was aluminum with a much lower melting point. It’s one of the reasons they’re using steel. We’ve seen much larger holes than that in previous tests. Some of the control fins burned completely through.
- GuB-42 5mo agoFor some of the tests, they removed a few tiles before launch, presumably to test that. Starship did fine.
- fooblaster 5mo agocoming back in one piece, and being good enough to use for 5 more missions are two very different things. For example, all existing reentry vehicles come back "fine" but they need to be completely remade to go up again.
- ceejayoz 5mo agoI remember this being the same argument used against the Falcon 9 when it first stuck its landings. "Oh, they'll need to do it 10x to be profitable!" Now they do, as a matter of course.
- fooblaster 5mo agoJust because you defeat popular consensus of what is possible in one place doesn't mean you can continue to do it again and again. This stuff is hard.
- hdgvhicv 5mo agoYes reusing falcon 9 was hard too. Being a cynical naysay isn’t hard.
- fooblaster 5mo agouncritically believing this design will succeed, despite having all the signs of Elon interfering and massively shifting requirements, isn't "hard" either
- laughing_man 5mo agoI doubt that. It's made of stainless steel. If it gets home safely they can patch it.
- peebee67 5mo agoDeliberately testing its survivability with that failure mode over different parts of the vehicle has been one of the major foci throughout the entire test campaign, and it has proven remarkably resilient. That generalisation pretty much does not hold for starship.
- aeternum 5mo agoThey already demonstrated that entire tiles can be removed without wrecking the spacecraft. The quarter thing may have been true for the space shuttle, that doesn't make it true in general.
