tater Posted April 16, 2018 Share Posted April 16, 2018 A ballute of some kind (assume disposable) could seriously reduce the wear on BFS coming in hot (Mars EDL, or hot Earth EDL) I'd think. Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted April 16, 2018 Share Posted April 16, 2018 (edited) First they will use balloons to deorbit the 2nd stage, Then they will realize that they can lift it with balloons, too. No more 1st stage. At last they will build Dragon v3 orbital airship with balloons, without rockets. It will get to Lagrange point, puncture several balloons to make some thrust and stay there To deorbit, or to lower the orbit, or even to go to the Moon, it will puncture several balloons more. Several balloons below the capsule will soften the landing. Edited April 16, 2018 by kerbiloid Quote Link to comment Share on other sites More sharing options...

kerbinorbiter Posted April 16, 2018 Share Posted April 16, 2018 It makes sense, the Falcon 9 uses helium in second stage why bot use the rest of the leftover helium in stage 2 to blow up balloons Quote Link to comment Share on other sites More sharing options...

Technical Ben Posted April 16, 2018 Share Posted April 16, 2018 Tried a Ballute in KSP... works great except I get flip city if I don't eject it. As it's KSP, I can just use a rocket landed option (either secondary engines, or the normal ones providing they perform). But mainly as no nozzle damage from pressure in KSP. Soft landings on engines is nice and elegant. But bouncy castles is probably cheaper. Quote Link to comment Share on other sites More sharing options...

Spaceception Posted April 16, 2018 Share Posted April 16, 2018 It's happening!! Any idea on how soon we could hear about TESS candidates? What will their numbering be like? TESS-1, TESS-234, similarly to like Kepler-556 or whatever? Quote Link to comment Share on other sites More sharing options...
StarStreak2109 Posted April 16, 2018 Share Posted April 16, 2018 I sincerely hope they are aware of that. Not that they are building a design error into that flying contraption of theirs... We wouldn't want that, would we...??? Quote Link to comment Share on other sites More sharing options...

TESS cannidates probably wont be available until at least the first, and probably the second, eliptical orbit periapse after the initial lunar slingshot. it's a 13.7 day orbit, so call it 27 days, an even Lunar Month from launch.

Well, the side protrusions of the "flying brick" Space Shuttle was called wings. Unless this one is going to be even more brick-ish in flying.

Ultimate Steve Posted April 16, 2018 Share Posted April 16, 2018 AWW YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!! Although the diagram seems to be outdated, with the same 106m height and only 2 SL Raptors, so no new info from that. BUT YEAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!
