James,
I have high hopes for the Delta Clipper and other SSTOs (Single Stage To Orbit) under development. The vast majority of energy is expended getting to LEO (Low Earth Orbit), once there it is pretty cheap energy wise to get anywhere else in the Solar System. Getting established on the moon is the key to the rest of the System IMO. It would be easy to launch material into Lunar orbit with electromagnetic launchers from the surface of the moon and there is plenty of Solar power for the taking there plus all the raw materials for making whatever is needed. A mission to Mars would most easily be assembled in Lunar orbit from resources mined on the Moon.

Given the absolute certainty that an asteroid or comet of sufficient size to destroy civilization or even all human life is going to hit Earth in the future (maybe tomorrow, in which case we are out of luck) unless we stop it, any price to get off planet will be cheap. This is part of why I support SDI research and development as it may offer a way to divert or destroy such a comet or asteroid, provided we see it in time.

We must declare war on possible extinction now. ggggg Had to tie this little essay to the topic somehow.
