Over the last few years, the National Aeronautics and Space Administration (NASA) has increasingly relied on its authority under the Space Act of 1958 to enter into agreements, commonly referred to as Space Act agreements (SAA), to stimulate private sector development of systems capable of transporting cargo and crew to the International Space Station and to assist partner firms in developing thei...
NASA: Key Management and Program Challenges
GAO-10-387T: Published: Feb 3, 2010. Publicly Released: Feb 3, 2010.
The National Aeronautics and Space Administration (NASA) is in the midst of many changes and one of the most challenging periods in its history. The space shuttle is slated to retire this year, the International Space Station nears completion but remains underutilized, and a new means of human space flight is under development. Most recently, the administration has proposed a new direction for NAS...
NASA: Constellation Program Cost and Schedule Will Remain Uncertain Until a Sound Business Case Is Established
GAO-09-844: Published: Aug 26, 2009. Publicly Released: Sep 25, 2009.
NASA's Constellation program is developing the Ares I Crew Launch Vehicle and the Orion Crew Exploration Vehicle as the agency's first major efforts in a plan to return to the moon and eventually send humans to Mars. GAO has issued a number of reports and testimonies on various aspects of this program, and made several recommendations. GAO was asked to assess NASA's progress in implementing GAO's...
NASA: Agency Faces Challenges Defining Scope and Costs of Space Shuttle Transition and Retirement
GAO-08-1096: Published: Sep 30, 2008. Publicly Released: Sep 30, 2008.
The Space Shuttle Program (SSP) is scheduled to retire in 2010, and the transition and retirement of its facilities and assets will be an immense undertaking involving approximately 654 facilities worth an estimated $5.7 billion and equipment with an estimated value of more than $12 billion. NASA plans to retire the SSP in 2010 to make resources available for the Constellation program, which is pr...
Space Acquisitions: Uncertainties in the Evolved Expendable Launch Vehicle Program Pose Management and Oversight Challenges
GAO-08-1039: Published: Sep 26, 2008. Publicly Released: Sep 26, 2008.
The Department of Defense (DOD) plans to spend over $27 billion acquiring launch services through the Evolved Expendable Launch Vehicle (EELV) program over the next 12 years. The EELV program uses two families of commercially owned and operated vehicles to launch satellites. Partly because the commercial space market did not develop as expected, the EELV program has undergone significant changes....
NASA: Challenges in Completing and Sustaining the International Space Station
GAO-08-581T: Published: Apr 24, 2008. Publicly Released: Apr 24, 2008.
The International Space Station (ISS), the most complex scientific space project ever attempted, remains incomplete. NASA expects the station's final construction cost will be $31 billion and expects sustainment costs through the station's planned retirement in fiscal year 2016 to total $11 billion. The space shuttle, the only vehicle capable of transporting large segments of the station into orbi...
