How many astronauts will be able to fit in Orion, and how long will it take for Orion to get to Mars, and are you considering a flyby mission (manned or unmanned) before sending crews to the surface?

How much longer than your current mission do you think a mission to Mars would be? And would you be willing to go on a mission of that duration?

What methods would be used to extract water from the Martian regolith, and how would it be purified afterwards?
