LONDON: On the 46th anniversary of the Moon landings, NASA says it wants to build a stepping stone base to Mars there. How? Perhaps with terraforming robots.
The idea is ambitious: Put people back on the Moon by 2021. And have them living up there by the 2030s.
Why? To save NASA billions of dollars in recurring launch costs.
How? By mining ice buried in the dark depths of Moon craters and converting it into rocket fuel.
This would dramatically reduce the need to build enormous, fuel-hungry rockets to lift cargoes out of Earth orbit. At the moment, private contractor SpaceX charges NASA $6400 for every kilogram it blasts into space.
Under the new proposal, cargoes could be sent to the Moon on much smaller and cheaper boosters, have their fuel-tanks topped-up, and continue on their way to Mars.
