Re: What about Oxygen?
All of those are good replies... I was just a bit concerned, because rockets do use a ridiculous amount of fuel... I kinda remembered, that the Falcon 9 FT first stage has a LOX capacity of 287400kg.... But then again, the first stage has to punch through a whole lot more atmosphere than the actual lander thingy, so the number I had in my head was just way too large.
