Any more than it did with the previous "we're going to Mars" pushes. (...) (...) (18 years ago, 4-Feb-07, to lugnet.space)

And honestly a rocket is not a very good way to use the energy: you have to launch at high speed (rocket equation (...) (18 years ago, 6-Feb-07, to lugnet.space)

Building a plane specifically designed for high altitude super sonic launching of "rocket ships" is one easy (...) (18 years ago, 7-Feb-07, to lugnet.space)

I agree, it's a nice mechanism to get away from the atmosphere problem, but so do balloons (for a far lower cost, actually). no offense to Space Ship (...) (18 years ago, 8-Feb-07, to lugnet.space)
