Mars water surprise in Curiosity rover soil samples
"If you think about a cubic foot of this dirt and you just heat it a little bit - a few hundred degrees - you'll actually get off about two pints of water - like two water bottles you'd take to the gym," Dr Leshin explained.This is huge for Mars exploration by humans.1. We can send unmanned expeditions to stockpile large tanks of water.2. This would allow us to literally 3D print structures on the surface and allow us to significantly decrease the amount of materials we need to transport to the surface in order to build a habitat.Edit: 
3. And ALICE rocket fuel could be created using this water and the aluminum found in the Martian soil.
