Space Transportation: Critical Areas NASA Needs to Address in Managing Its Reusable Launch Vehicle Program
GAO-01-826T: Published: Jun 20, 2001. Publicly Released: Jun 20, 2001.
This testimony discusses the National Aeronautics and Space Administration's (NASA) X-33 and X-34 reusable launch vehicle programs. The two programs experienced difficulties achieving their goals primarily because NASA did not develop realistic cost estimates, timely acquisition and risk management plans, and adequate and realistic performance goals. In particular, neither program fully (1) assess...
Space Station: Cost to Operate After Assembly is Uncertain
NSIAD-99-177: Published: Aug 6, 1999. Publicly Released: Aug 18, 1999.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) estimate for the cost to operate the International Space Station after assembly is completed, focusing on: (1) whether any space station-related costs are not included in NASA's estimate; (2) the level of uncertainty in the cost estimate for operations, especially with regard to the potenti...
