Space Station: Delays in Dealing With Space Debris May Reduce Safety and Increase Costs
IMTEC-92-50: Published: Jun 2, 1992. Publicly Released: Jun 2, 1992.
Pursuant to a congressional request, GAO evaluated the National Aeronautics and Space Administration's (NASA) progress in its: (1) incorporation of the current estimate of the debris environment into space station requirements; (2) effort to keep the debris environment model current; and (3) overall strategy to protect the station from space debris of various sizes.GAO found that: (1) most current...
Space Shuttle: NASA Faces Challenges in Its Attempt to Achieve Planned Flight Rates
NSIAD-92-32: Published: Dec 6, 1991. Publicly Released: Jan 8, 1992.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) future space shuttle flight plans, focusing on the: (1) factors associated with achieving planned flight rates; (2) processes to ensure that NASA does not compromise safety by increasing flight rates; (3) impact of variations in flight rate estimates on subsystem and spare parts procurement...
Space Communications: Better Understanding of Scheduling System Limitations Needed
IMTEC-91-48: Published: Sep 17, 1991. Publicly Released: Sep 20, 1991.
Pursuant to a congressional request, GAO reviewed the efficiency and effectiveness of the National Aeronautics and Space Administration's (NASA) system for scheduling usage of the Tracking and Data Relay Satellite System (TDRSS).GAO found that: (1) since scheduling TDRSS usage is a complicated process, spacecraft project users generate a tentative schedule of the precise contact times and types of...
Technology Development: Future Use of NASA's Large Format Camera Is Uncertain
NSIAD-90-142: Published: Jun 6, 1990. Publicly Released: Jun 6, 1990.
In response to a congressional request, GAO reviewed: (1) why the National Aeronautics and Space Administration (NASA) had stored the Large Format Camera (LFC) since its first and only flight in 1984; and (2) possible future LFC uses.GAO found that: (1) NASA had successfully demonstrated LFC capabilities by showing that high-quality pictures could be produced in space; and (2) NASA acquired high-r...
Space Program: Space Debris a Potential Threat to Space Station and Shuttle
IMTEC-90-18: Published: Apr 6, 1990. Publicly Released: Apr 23, 1990.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) response to the space debris issue, focusing on: (1) its plans and cost estimates for protecting the planned space station from debris; (2) NASA and Department of Defense (DOD) debris tracking capabilities; and (3) the effect of orbital debris on space shuttle operations.GAO found that: (1)...
Space Shuttle: The Future of the Vandenberg Launch Site Needs to Be Determined
NSIAD-88-158: Published: Aug 3, 1988. Publicly Released: Aug 3, 1988.
GAO examined the Air Force's deactivation efforts for the space shuttle's Vandenberg Launch Site (VLS) and its plans for maintaining and reactivating the site.GAO found that the Air Force: (1) planned to complete the few remaining VLS deactivation tasks during fiscal years 1988 and 1989; (2) placed VLS in a low-maintenance status due to limited funding and the lack of a shuttle launch schedule; an...
Implications of Joint NASA/DOD Participation in Space Shuttle Operations
NSIAD-84-13: Published: Nov 7, 1983. Publicly Released: Nov 23, 1983.
Pursuant to a congressional request, GAO provided its assessment of joint National Aeronautics and Space Administration (NASA) and Department of Defense (DOD) participation in space shuttle operations and Air Force activities concerned with developing and acquiring a dedicated DOD shuttle operations control facility.GAO found that, with the advent of the space shuttle, a trend has developed toward...
NASA Must Reconsider Operations Pricing Policy To Compensate for Cost Growth on the Space Transportation System
MASAD-82-15: Published: Feb 23, 1982. Publicly Released: Feb 23, 1982.
GAO reviewed the National Aeronautics and Space Administration (NASA) pricing policy and operating cost for the Space Transportation System (STS) to determine the overall effect that STS cost increases would have on future NASA budget requests and on its other research and development.GAO found that, based on estimated future costs, NASA established a 3-year, $18 million fixed price for commercial...
DOD Participation in the Space Transportation System: Status and Issues
MASAD-81-6: Published: Feb 28, 1981. Publicly Released: Feb 28, 1981.
The operational availability of the Space Transportation System (STS) has been delayed 3.5 years. Delays have resulted from identification of new requirements, funding constraints, and development difficulties with the system. To date there has been no known operational degradation in Department of Defense (DOD) space capabilities. However, the cost of DOD participation in the program has grown fr...
NASA Should Provide the Congress Complete Cost Information on the Space Telescope Program
PSAD-80-15: Published: Jan 3, 1980. Publicly Released: Jan 3, 1980.
The National Aeronautics and Space Administration (NASA) plans to launch a space telescope aboard the space shuttle in 1983. The program is on schedule and within its budget, and all the telescope's scientific instruments should meet or exceed the established performance requirements. GAO believes that NASA should provide Congress with better financial information on this project.On a recent statu...
