It's supposed to be re-usable. Although it's cheating, as they throw the rocket away. Then again, the shuttle itself threw two rockets and a honking great tank away on every launch. Well I know they re-used bits of the SRBs, but not with the hoped for success.
SpaceX are getting pretty shuttley though. They've designed a re-usable capsule, and the first stage of one of their rockets is doing a test landing next week.
