quote: A manned mission to Mars is just fantasy circle jerk, the US gov is basically bankrupt and wastes more money on social programs than defense and space combined.
quote: He’s not saying those programs are a waste of money.

quote: The funding bill planned to from 2006 to 2010 slowly grow NASA's funding from $16.5B USD to $18.5B USD, in order to keep up with costs of funding the preparation for a Moon mission.
quote: 139,808,518 miles from Earth -- at its closest point -
quote: In other words: even if there were a giant lake of pre-refined rocket fuel sitting on the Moon, it still would be more efficient to just blast off straight to mars.
quote: And if they dig into cave or live underground, how much money has to be spent in order to create a living space to cater for the colonists need.
quote: You can't just go straight from Earth to Mars, silly! Going to Mars realistically requires infrastructure in space. And the ISS won't be around much longer. So that's where a Moon base comes in.
quote: It means you don't have to lug rocket fuel from Earth to the Moon.
quote: The moon base is cool-sounding, but a Mars vehicle could be assembled in LEO, couldn't it?
quote: Hydrogen on the moon is great, but you also need oxygen to burn it. You use 6x as much oxygen (by mass), which would indicate even more need to have a local source of oxidizer.
quote: Realistically? No. Constructing things in a zero gravity environment is extremely awkward and difficult. We have NO idea how to even do it.
quote: Did you miss the part where the Hydrogen is in the ice?
quote: However, I hold that you still don't need a moon base to assemble the vehicle.
quote: A permanent Moon base could give us the expertise to handle these issues
quote: Then you can do a much longer burn and have a shorter trip to Mars.
quote: You're getting pushback because the Moon lack the raw material you are talking about!
quote: Why are you adding all those trips? The Moon would be colonized, you'll leave straight from the Moon to Mars. Hellooo, wtf...
quote: It means you don't have to lug rocket fuel from Earth to the Moon. The Moon HAS it's own fuel just waiting to be used.
quote: I still prefer the idea of an elevator to LEO built on Earth. Seems more practical, long-term.
