[Smithsonian] Scientists Discover That Mars is Full of Water - Page 6

post #51 of 52
If they have access to a lot of water then they could, theoretically, make it a return mission.

With enough water, unlimited power (nuclear or even solar) and enough time you can break it down to hydrogen and oxygen. Pressurise and store the hydrogen and oxygen and you have rocket fuel.

Now you couldn't do a launch like we do on Earth, the towers and so on would be too hard to construct, but you could launch something along the lines of Space Ship One - a super high flying plane.

It would mean sending out some extra hardware, or designing the outgoing craft with return in mind, but it removes the biggest challenge - carrying enough fuel for the return trip.

Plus with SpaceX operating its relatively cheap cargo service we can get a lot of material into orbit - then slowly send it on it's way to Mars. It doesn't matter if cargo spends a year or two travelling.
