- While I hate to disagree with anyone picking on Nick :-) :-), note that
- there was no S-III stage (the Saturn V was S-IC, S-II, S-IVB) and even
- the S-IVB's on-orbit lifetime was only a few hours.
-
- However, hauling substantial amounts of LH2 to the Moon appears to pose
- no particular problem. The Apollo spacecraft all did it for their fuel
- cells, and Griffin's FLO proposal uses LH2-LOX engines (RL10s, in fact)
- in the lander's descent stage.
