I expect the more difficult part is getting the necessary fuel to Mars to escape. Obviously you could do it if you took enough trips, but that would likely be prohibitively expensive.
- baq 12y agothe plan that makes most sense is to produce fuel on site. allegedly there's water below Mars surface, so LOX/LH should be doable. maybe there's more stuff to synthesize methane, RP-1 or other fuels.
- tsotha 12y agoOne plan I've seen for ISRU on the moon is to use a Al-Lox hybrid engine, since Al2O3 is all over the moon's surface. I wonder if there's enough on Mars to do the same thing, or if you could do something with iron oxide.
