Yesterday SpaceX launched its first satellite payload into geosynchronous orbit, at a price 75% lower than currently charged by other commercial launch providers.  Even more impressive is the fact that SpaceX has been steadily developing the required technology to slow down and return first stage boosters back to earth, which would even further decrease costs.

Watching this take off and landing test of the SpaceX Falcon 9 rocket reminds me of Buck Rogers:
