Would on-orbit refueling work with cryo? I imagine the fuel/oxidizer would boil away too fast for that to work well, unless you sent everything up at once perhaps.
- dasmoth 14y agoDepends how well you insulate things. There are plans around to get LOX boil-off to zero and keep LH2 boil-off pretty low.
- ChuckMcM 14y agoThe ULA guys are talking about keeping cryo fuels in depots. They have some thoughts about hydrogen boil off (which they use in their internal combustion engine (H2 + O2) to both do station keeping and temperature management. I have not seen proposals for on-orbit cryo fuel transfer. But I'm sure they are out there.
