    Your source is outdated. That's what they had hoped to achieve from the Shuttle, but they found it was more expensive to operate than they predicted. Yes, the shuttle is reusable; but getting it flight-ready after each mission is where the vast majority of expenses come from. The Shuttle itself is 166,000 Ib completely unloaded, yet its payload capacity is some 50,000 Ib. That means you're sacrificing three times more for the vehicle than the payload. It would have been far better if they just skipped with the shuttle altogether and redesigned the external tank to function as a rocket stage. That would then allow you to potentially lift four times the cargo for roughly the same price as a single shuttle launch.
