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...
International Space Station: U.S. Life-Cycle Funding Requirements
NSIAD-98-147: Published: May 22, 1998. Publicly Released: Jun 1, 1998.
Pursuant to a congressional request, GAO reviewed issues associated with the National Aeronautics and Space Administration's (NASA) International Space Station program, focusing on: (1) estimates of the station's development, assembly, and operations costs and comparing this estimate with the estimate in GAO's June 1995 report; (2) program uncertainties that may affect those costs; (3) potential d...
Environmental Cleanup Costs: NASA Is Making Progress in Identifying Contamination, but More Effort Is Needed
NSIAD-97-98: Published: Jun 27, 1997. Publicly Released: Jul 28, 1997.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) environmental cleanup costs, focusing on NASA's: (1) determination of the extent of contamination it may be responsible for cleaning up and progress in its cleanup program; (2) cost estimates for accomplishing cleanup; and (3) efforts to determine whether "potentially responsible parties" s...
Space Station: Cost Control Difficulties Continue
NSIAD-96-135: Published: Jul 17, 1996. Publicly Released: Jul 24, 1996.
Pursuant to congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) International Space Station (ISS) program, focusing on: (1) the program's cost and schedule status; and (2) NASA efforts to improve its cost reporting.GAO found that: (1) over the past several years, ISS flight hardware has been produced; (2) as of April 1996, the ISS prime contract was about...
Navy Aviation: F/A-18E/F will Provide Marginal Operational Improvement at High Cost
NSIAD-96-98: Published: Jun 18, 1996. Publicly Released: Jun 18, 1996.
GAO reviewed the Navy's plan to procure with F/A-18E/F aircraft, focusing on: (1) whether operational deficiencies in the F/A-18C/D cited by the Navy to justify the need for the F/A-18E/F have materialized and, if they have, the extent to which the F/A-18E/F would correct them; (2) whether the F/A-18E/F will provide an appreciable increase in operational capability over the F/A-18C/D; and (3) the...

NSIAD-94-253: Published: Aug 16, 1994. Publicly Released: Aug 16, 1994.
Pursuant to a congressional request, GAO reviewed the Department of Defense's (DOD) space programs and activities.GAO found that: (1) since 1989, the government's efforts to acquire a new space launch system have been unsuccessful; (2) the administration's current national space transportation strategy does not identify a mechanism for implementing high-level management within the Executive Office...
Military Space Programs: Comprehensive Analysis Needed and Cost Savings Available
T-NSIAD-94-164: Published: Apr 14, 1994. Publicly Released: Apr 14, 1994.
GAO discussed two Department of Defense (DOD) satellite programs. GAO noted that: (1) DOD has an opportunity to assess its needs for early missile warning information, since it cancelled the most recent follow-on program for its Defense Support Program (DSP) and replaced DSP with the Alert, Locate, and Report Missiles System (ALARM) which has more tactical emphasis; (2) DOD needs to review and val...
