This film makes no sense , its a insult to basic intelligence !!
why is he trying to get Oxygen and hydrogen from desert sand and earth, to then turn into water,, very energy efficient ?? .. He would be better off bringing more Gas bottles..
Why dose he not use condensation from the contaminated water supply to get rid of the contamination ? , rather than using condensation from two dead weedy looking plants...
I think NASA needs to find better astronauts ..
