Raven Industries Posted November 18, 2019 Share Posted November 18, 2019 My back of the napkin math says that assuming SpaceX reaches its 100 ton to lunar surface goal, and ignoring volume constraints, it could take an entire fully fueled SLS to the surface of the Moon in ~25 launches. If you dump the fuel, it only takes ~3 launches. Who knows, that might actually be cheaper than making SLS fly. Quote Link to comment Share on other sites More sharing options...

Same that will happen with NASA's 6-phase Mars sample return shoebox - Starship will get there and the astronauts will pose for a photo next to it on break from shoveling 50 tons of rock into their cargo bay.

If you brought the solid fuel (IDK how many launches that would take) and then made the hydrolox from ice they may be able to launch it from the moon assuming they built a launch pad.

Ultimate Steve Posted November 18, 2019 Share Posted November 18, 2019 We're not supposed to directly copy and paste pictures from the NSF thread but there are pictures there suggesting that the Starship Mk1 was pressurized, at least in the top tank.

sh1pman Posted November 19, 2019 Share Posted November 19, 2019 (edited) So how many refillings does it need to land 100t on the Moon and return? Must be around 6-7 in GTO, right? Edited November 19, 2019 by sh1pman Quote Link to comment Share on other sites More sharing options...

Depends on if it has to return. CLPS is just landing cargo. For just landing 5-6 from LEO? Quote Link to comment Share on other sites More sharing options...

RealKerbal3x Posted November 19, 2019 Share Posted November 19, 2019 I’ve always wondered how Falcon 9 boosters are returned to horizontal position after landing (or returning to port on a droneship)? How do they do it? Quote Link to comment Share on other sites More sharing options...
