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...
Military Space Programs: Opportunities to Reduce Missile Warning and Communication Satellites' Costs
T-NSIAD-94-108: Published: Feb 2, 1994. Publicly Released: Feb 2, 1994.
GAO discussed the status and future plans for the Department of Defense's (DOD) Defense Support Program (DSP) and Milstar satellite communications system. GAO noted that: (1) DOD has decided to terminate and replace its current DSP follow-on program to reduce costs and consider new tactical requirements; (2) DOD needs to evaluate the new DSP system's effectiveness and affordability before systems...
Hubble Space Telescope
NSIAD-93-247R: Published: Jul 29, 1993. Publicly Released: Jul 29, 1993.
GAO provided information on the National Aeronautics and Space Administration's (NASA) mission to service the Hubble Space Telescope (HST). GAO found that: (1) NASA use of independent review teams and input from individual experts has increased the probability of successfully servicing HST because these sources have effectively identified potential problems and ensured implementation of solutions;...
