Unobscured Vision Posted February 16, 2018 Share Posted February 16, 2018 Yeesh, really big one. That'll be a good one. Not the heaviest they've pushed uphill, but it's a good 'un. Link to comment Share on other sites More sharing options...
anthdci Posted February 16, 2018 Share Posted February 16, 2018 looks like two expendables in a row then. Unless this is an early block 5 which I doubt. Link to comment Share on other sites More sharing options...
DocM Posted February 16, 2018 Author Share Posted February 16, 2018 (edited) Block 5 starts with core B1046.1 You'll know it when you see it. Unobscured Vision 1 Share Link to comment Share on other sites More sharing options...
Unobscured Vision Posted February 16, 2018 Share Posted February 16, 2018 They won't be tossing away any Block-5's ... unless they want to make a statement. I think there will be a "special" mission they'll wanna do that with -- perhaps a super-heavy CRS one with a Cargo Dragon absolutely stuffed to the gills, loaded down as heavy as they can get it ...

DocM Posted February 16, 2018 Author Share Posted February 16, 2018 (edited) The most likely Block 5 ditching would be an expended Falcon Heavy center core, but that only gains you about 5% in payload mass - about 3,190 kg to LEO and less elsewhere.

anthdci Posted February 24, 2018 Share Posted February 24, 2018 how much repair work was needed for OCISLY after FH? Seems like a quick turnaround, I thought it took out 2 engines at least. Link to comment Share on other sites More sharing options...
flyingskippy Posted February 24, 2018 Share Posted February 24, 2018 Do they mean the pneumatic separation system or do they really pressurize the whole fairing? Link to comment Share on other sites More sharing options...
DocM Posted February 26, 2018 Author Share Posted February 26, 2018 (edited) The fairings internal pressure is ambient. The consensus seems to be they're working on the system which pressurizes the cold gas thrusters used for recovery maneuvering. Launch: March 1 Window: 0034 Eastern, 0534 UT The short gap between Falcon 9 and Atlas V GOES-S at 1702 Eastern, 2202 UT is possible because of Falcon 9's Autonomous Flight Safety System (AFSS).

DocM Posted March 1, 2018 Author Share Posted March 1, 2018 Quote If SpaceX still intends to recover the first stage, the earliest the launch could take place is next week. Or, they could expend it. Lots of that happening with Block 5 so close. Unobscured Vision 1 Share Link to comment Share on other sites More sharing options...
