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...
Space Program Safety: Funding for NASA's Safety Organizations Should Be Centralized
NSIAD-90-187: Published: Aug 16, 1990. Publicly Released: Aug 16, 1990.
GAO reviewed the National Aeronautics and Space Administration's (NASA) safety-related programs to determine whether NASA complied with recommendations that it establish an independent organization with direct authority for safety programs.GAO found that: (1) NASA established the Office of Safety, Reliability, Maintainability and Quality Assurance (SRM&QA), under which field center safety organiza...
Space Transportation: NASA Has No Firm Need for Increasingly Costly Orbital Maneuvering Vehicle
NSIAD-90-192: Published: Jul 31, 1990. Publicly Released: Jul 31, 1990.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) Orbital Maneuvering Vehicle (OMV) program, focusing on: (1) the need to continue the OMV program in light of reductions in OMV capabilities; and (2) the reasons for changes in OMV program costs and schedules.GAO found that: (1) the OMV conceptual design has evolved over a number of years; (...
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 Operations: NASA's Communications Support for Earth Orbiting Spacecraft
IMTEC-89-41: Published: Apr 7, 1989. Publicly Released: May 12, 1989.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) plans for providing emergency backup communications support for earth-orbiting spacecraft.GAO found that NASA: (1) before implementation of its space-based Tracking and Data Relay Satellite System (TDRSS), primarily relied on its worldwide network of ground stations to provide communication...
