Recent NASA estimates peg the shuttle program's cost through the end of last year at $209 billion (in 2010 dollars), yielding a per-flight cost of nearly $1.6 billion. And the orbiter fleet never flew more than nine missions in a single year. The shuttle program is drawing to a close...

Because NASA lacked support for the actual cost of completed space station elements and subsystems, GAO could not determine whether NASA's costs were reasonable. Also, the act does not require NASA to charge all relevant obligations against the space station and shuttle limits. As a result, ...
NASA's cost estimates at each stage have been very optimistic, and the GAO objects to the agency's decision to monitor cost via the five-year production and operations cost estimate. The GAO report says these are poor tools to control costs, and NASA hasn't even been consistent about updat...

Now,task force operations are expected to cost $6 million, based on a return toflight in July. Drachlis said 90 percent of the moneyhad been spent by late May. Included in the total: the cost of an office near JohnsonSpace Center in Houston; hourly wages and travel expenses for the 26...
It was lampooned after its launch when a wonky mirror meant that its images were blurred almost to the point of uselessness, and a mission by the Space Shuttle to fix the problem cost hundreds of millions of dollars. 在它发射之后因为一个镜片晃动造成像模糊而被讽刺是毫无用处的,并且一个用航...
The Enterprise cost around $10 billion to construct and almost a decade. It became the first shuttle to fly freely when a Boeing 747 airplane lifted it 25,000 feet and let it glide. "The space shuttle prototype ...
