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...
Weather Satellites: Economies Available by Converging Government Meteorological Satellites
NSIAD-87-107: Published: Apr 23, 1987. Publicly Released: Apr 23, 1987.
GAO reviewed the United States' two separate, but similar, polar-orbiting meteorological satellite systems to determine if the two systems could be combined to eliminate duplicative practices and overlapping functions, and continue to provide necessary services to the systems' users.GAO found that: (1) national policy supports the convergence of polar meteorological satellite systems; (2) converge...
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...
A Second Launch Site for the Shuttle? An Analysis of Needs for the Nation's Space Program
PSAD-78-57: Published: Aug 4, 1978. Publicly Released: Aug 4, 1978.
The National Aeronautics and Space Administration (NASA) is constructing space shuttle facilities at Kennedy Space Center (KSC), the primary launch, landing, and orbiter refurbishment site which is scheduled to become operational in mid-1980. A second site, Vandenberg Air Force Base (VAFB), will be funded by the Department of Defense (DOD) and is expected to become operational in June 1983 at a co...
National Aeronautics and Space Administration Should Provide the Congress with More Information on the Pioneer Venus Project
PSAD-77-65: Published: Nov 7, 1977. Publicly Released: Nov 7, 1977.
Pioneer Venus is a space flight project designed to increase knowledge of our nearest planetary neighbor and to obtain information for solving atmospheric problems on earth. The project involves launching two spacecraft to Venus in 1978.Costs for the project have grown and technical problems have cropped up in the project. The National Aeronautics and Space Administration's (NASA'S) quality assura...
NASA Report May Overstate the Economic Benefits of Research and Development Spending
PAD-78-18: Published: Oct 18, 1977. Publicly Released: Oct 18, 1977.
The National Aeronautics and Space Administration (NASA) contracted with Chase Econometrics Associates, Inc., to evaluate how research and development (R&D) spending affects the U.S. economy.The Chase report "The Economic Impact of NASA R&D Spending" concluded that this spending produced many benefits between 1960 and 1974, although it did not try to evaluate how effectively NASA carried out its p...
The SEASAT-A Project: Where It Stands Today
PSAD-77-126: Published: Sep 16, 1977. Publicly Released: Sep 16, 1977.
SEASAT-A is an ocean dynamics satellite scheduled for launch in 1978 with sensors to measure winds, waves, ocean currents, sea temperatures, ice coverage, and atmospheric and water vapor.The National Aeronautics and Space Administration (NASA) has experienced cost, schedule, and performance difficulties with the SEASAT-A because of technical problems and an estimated $5 million increase in the cos...
