We have a special page just for this sort of thought... mark.
I disagree with you entirely, Astromark. A simple nested collapsable tube (10 sections, each 12 feet long, for about 100 feet of acceleration). Propulsion system? Compressed air. G's? Let's say 5 Gs (most satellites can handle that).

5 Gs for 100 ft. How much delta-V would that provide? Would it be worth the weight (probably 250 lbs), or could we do much better with an ion engine over a much longer duration?

It's not ATM. It's simply a different look at getting a satellite headed in the right direction.

If I set the budget, we'd have Ares and more. Unfortunately, I don't set the budget, and Ares is just too expensive and too far out for us to accomplish our goals within the budget we were given.

If we halt the ISS, all versions of Ares, and transport Orion and Altair aboard DIRECTv3's Jupiter family of Shuttle-Derived Launch Vehicles, we just might make it back to the Moon by 2020.
