What is being done to reduce the cost it takes to get things into space? The cost just to get into orbit is big.

Studies for reusable rockets.
Not sure what the breakdown is for the "Curiosity" mission to Mars, I think about 2.5bil total. Thats a big difference then how Nasa started, looking at low cost!
The pathfinder mission was done for under 300 mil, Yeah what happened to low cost.
I wonder how far a helocopter could get you! It's already built to land, even one of those Hurriar jets would be great!
Helicopters need a dense atmosphere to support their rotors. So they can't go all that high up. What is more promising is a technology similar to Virgin Galactic'c White Knight or to how Boeing X-37 is launched. The main draw back is that the payload may not weight much.
My money's on three ideas: air-augmented rockets (to draw oxidizer in from the atmosphere you're flying through, it can save something like 40% of your mass on the pad but requires some nasty aerodynamic hurdles to get through) and multi-staged air-aspirated motors: ramjet, scramjet, pulsed scramjet, then going for orbit (but it's hard to tell how this will work out, if you'll add more mass with your propulsion units than you would lose from the fuel saved).
Hundreds of little things are being done, and some big ones (CCDev), but it's not like it's something that is able to be done overnight.
Red bull stratos, X-prize. Are they just the start?
