Houston replies: So just solve it! No option. No excuse.
628,540 gallons (372,800 pounds) are used in all during
Shuttle vehicle loading. Before final loading begins, some
liquid hydrogen is used to pre-chill fuel lines and the hydrogen
compartment of the tank; additionally, during fueling,
some boils off as a gas.
The Power Reactant Storage and Distribution System
(PRSDS) also uses liquid hydrogen. About 2,000 gallons
are used in all for PRSDS loading because of pre-chill operations,
boil-off and ground storage tank dumping.
Gaseous hydrogen is used for fuel cell purging during
operations in the Orbiter Processing Facility and while the
orbiter is on the launch pad.
The hydrogen used at KSC is produced from natural
gas by a steam-reforming process in New Orleans, La. It is
shipped in 13,000-gallon mobile tankers.
The current price of hydrogen is 98 cents a gallon.

Let's say we knew the date of the end of the world and it's next year(comet impact or whatever). Wouldn't you be happy and proud if it was your kids that were the ones being sent out to colonize space?
I'd wager that if you polled NASA employees and astronauts, you'd find a very high degree of happiness and motivation. I'd say that the people that have been working with lunar missions, Mars rovers and the hubble telescope(when they are working) are the most satisfied people on the planet.

Life about Happiness..!
I fear that such unnatural surroundings and pressures will make us even more miserable than we are today..!
I doubt our cavemen ancestors were more miserable, soulless and stressed out than we are..!
For space to be feasible we will have to find a planet hospitable for life. There hasn't been one discovered yet..!
Man in space is a waste given our current energy dilemma. I would however continue with R&D satellites and space probes..!
We're also preparing for peak because we want to survive and we want our kids to survive. Isn't that what colonizing space is also attempting to do..?
The planet currently thinks in a capitalist way and this system is based around the individual being able to achieve happiness for himself through financial success and the pursuit of his own individual success. Most peoples career goals involve getting a job, having a family and settling down in the suburbs all nice and secure..!
It will take a revolutionary step in human thinking to overcome these obstacles let alone even believe we can live on Mars..!
Until that happens I'm going to pack my shotgun, my tent and my canned soup and head for the hills..!
628,540 gallons of propellants & fluids..!
There certainly exists NO planet in the solar system that can support human life, other than earth of course, and lots of places on earth are impossible too..!
How many people could you save? Certainly not billions. Or even millions..!
To colonise space you'd need to be a rich, advanced, enormous energy consuming industrial nation..!
Why can't we just scale everything down and return to a simpler more happy way of life, on Earth? If some comet comes, at least we'd die happy..!
Americans did that to get to the Moon..!
The reality of diminishing energy supplies is what happened..!
Taikonauts & Astronauts shaking hands..!
