But if we're talking colony, mass is going to be huge so Mars might actually make more sense from a pure "how much fuel will we need to move all that stuff" point of view.
Sending humans at all is the silly part IMO, send robots to build/maintain everything, or if you can't, send other robots to learn how to build robots to build everything. |
Is this where they are determining that they resupply every two years? Is that the approximate time between launch windows for a earth/mars transfer?
