Writing off the booster is cheaper than losing the payload, at least until companies take advantage of cheap launch costs with cheaper payloads Pretty sure that is in software already as in the extra fuel is an emergency reserve. This was one of the thought behind powered landings. It would make sense to use old boosters for starlink launches as the satellites are cheap Quote Link to comment Share on other sites More sharing options...

NSEP Posted June 30, 2018 Share Posted June 30, 2018 (edited) Will it only be Block 5s from this point or will there be more B3 launches? Edited June 30, 2018 by NSEP Quote Link to comment Share on other sites More sharing options...

Xd the great Posted July 1, 2018 Share Posted July 1, 2018 Block 4 is thrown away as it is designed to demonstrate reuseability. Therefore, the cost and time of refurbrishment is high. Block 5 is designed for more rapid reuseability, probably under 24 hours. Also, these are cheaper to reuse. Bye, block 4 rockets. Quote Link to comment Share on other sites More sharing options...
TheDestroyer111 Posted July 2, 2018 Share Posted July 2, 2018 Block 5 will still get improved, by the time it gets to 24 hour multi-reuse it might well be called "block 6", however these upgrades are likely going to come out with every launch, so no more revolutionary "blocks".

I never thought that block 6 is real. I thought block 5 is final version, designed to man the ISS Quote Link to comment Share on other sites More sharing options...

But they need to stop making changes in order for it to get man-rated for Crew Dragon. So it's likely that this will be a stable design for some time, unless the early block 5 flights uncover some catastrophic unanticipated issues.

Pretty sure Block 5 is not getting any more improvements as it simply can't if they want to man rate it. There won't be any more versions. Unless we're talking FH launches. Even Block 5s need to be modified to be used as FH boosters and core stages (AFAIK). Quote Link to comment Share on other sites More sharing options...

Under Section 1605 of the current draft, the Evolved Expendable Launch Vehicle (EELV) program is renamed the “National Security Space Launch Program”. This is a step forward in recognizing that reusability can and should be part of our nation’s launch portfolio, but the key developments follow next. That same section also outlines a requirement that the Secretary of Defense pursue a strategy that includes reusability — partial or fully reusable rockets — in national security launches; mandates the continuation of certification processes to validate the use of these components; and requires justification for why a national security launch contract awards excludes reusable rockets.

Wjolcz Posted July 5, 2018 Share Posted July 5, 2018 3 minutes ago, NSEP said: You don't have to use the main engines at all to land back and be reused. You can easily just glide back to destination, especially when the main engines cut-off at near-orbital velocity, when you just have to wait an hour to hit the atmosphere and glide back to the space centre and land on a runway. I don't think an RTLS would be possible in this scenario. And the payload would probably be reduced too. I don't think discussing reusable SLS makes much sense. Especially that this is the SpaceX thread and NASA doesn't plan to do anything like that anyway. Quote Link to comment Share on other sites More sharing options...
