From Steve Blyth
Can anyone explain why George Bush is so keen to climb out of one deep gravity well (Earth) just to jump down another (Mars)?
It makes much more sense, if (wo)manned space exploration is the aim, to target low-mass bodies such as moons, asteroids and comets where habitation resources and fuel for (far easier) onward trips also exist. Surely the moral is, when you’re in a hole, stop digging; not, let’s dive in another! Or is this just a case of the mountaineer’s motive “Because it’s there”?
