The really exciting thing is that they're working on making things reusable since that seems to be the major barrier to affordable launches. Things like reusable rocket stages: http://spaceflightnow.com/news/n1209/24grasshopper/ and reusable spacecraft: http://en.wikipedia.org/wiki/Dragon_(spacecraft)

I always found it mindblowing that we spent billions on systems that we then destroyed to get things out of our gravity well. I'm really exited about what the future will bring, what a great time to be alive.
