Environmental Satellites: Focused Attention Needed to Mitigate Program Risks
GAO-12-841T: Published: Jun 27, 2012. Publicly Released: Jun 27, 2012.
As requested, this statement summarizes our two reports being released today on (1) the status, plans, and risks for JPSS and (2) the status, schedule management process, and risk management process within the GOES-R program. We found that the JPSS cost and GOES-R contractor cost data were sufficiently reliable for our purposes. Further, while we found that the GOES-R schedule and management reser...
NASA: Assessments of Selected Large-Scale Projects
GAO-12-207SP: Published: Mar 1, 2012. Publicly Released: Mar 1, 2012.
GAO assessed 21 NASA projects with a combined life-cycle cost that exceeds $43 billion. Of those 21 projects, 6 were in an early phase of development called formulation, and 15 had entered the implementation phase where cost and schedule baselines were established. Five of the 15 projects in implementation successfully launched in 2011, and two of them met their cost and schedule baselines. NASA...
Commercial Launch Vehicles: NASA Taking Measures to Manage Delays and Risks
GAO-11-692T: Published: May 26, 2011. Publicly Released: May 26, 2011.
Since the National Aeronautics and Space Administration (NASA) created the strategy for the Commercial Orbital Transportation Services (COTS) project in 2005, the space landscape has changed significantly--the Space Shuttle program is retiring and the Ares I will not be available--increasing the importance of the timely development of COTS vehicles. The lack of alternatives for supplying the Inter...
NASA: Assessments of Selected Large-Scale Projects
GAO-10-227SP: Published: Feb 1, 2010. Publicly Released: Feb 1, 2010.
The National Aeronautics and Space Administration (NASA) plans to invest billions in the coming years in science and exploration space fl ight initiatives. The scientifi c and technical complexities inherent in NASA's mission create great challenges in managing its projects and controlling costs. In the past, NASA has had diffi culty meeting cost, schedule, and performance objectives for many of i...
Commercial Space Transportation: Development of the Commercial Space Launch Industry Presents Safety Oversight Challenges for FAA and Raises Issues Affecting Federal Roles
GAO-10-286T: Published: Dec 2, 2009. Publicly Released: Dec 2, 2009.
Since the Government Accountability Office (GAO) reported on the commercial space launch industry in 2006, the industry has evolved and moved further toward space tourism. Commercial space tourism promises to make human space travel available to the public for the first time. The Federal Aviation Administration (FAA) oversees the safety of commercial space launches, licensing and monitoring the sa...
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 Has Taken Steps Toward Making Sound Investment Decisions for Ares I but Still Faces Challenging Knowledge Gaps
GAO-08-51: Published: Oct 31, 2007. Publicly Released: Nov 29, 2007.
One of the first steps in the National Aeronautics and Space Administration's (NASA) efforts to implement the President's plan to return humans to the moon and prepare for eventual human space flight to Mars is the development of the Ares I Crew Launch Vehicle. In 2005, NASA outlined a framework for implementing the President's plan and has awarded contracts for Ares I and the Orion Crew Explorati...
NASA's Space Vision: Business Case for Prometheus 1 Needed to Ensure Requirements Match Available Resources
GAO-05-242: Published: Feb 28, 2005. Publicly Released: Mar 22, 2005.
In 2003, the National Aeronautics and Space Administration (NASA) initiated the Prometheus 1 project to explore the outer reaches of the Solar System. The Prometheus 1 spacecraft is being designed to harness nuclear energy that will increase available electrical power from about 1,000 watts to over 100,000 watts and enable the use of electric propulsion thrusters. Historically, NASA has had diffic...
Space Shuttle: Further Improvements Needed in NASA's Modernization Efforts
GAO-04-203: Published: Jan 15, 2004. Publicly Released: Feb 13, 2004.
The Columbia tragedy has accentuated the need to modernize the 20-year-old space shuttle, the only U.S. launch system that carries people to and from space. The shuttle will now be needed for another two decades. As it ages, the spacecraft's components will also age, and it may become increasingly unreliable. GAO examined the National Aeronautics and Space Administration's (NASA) plans to upgrade...
Space Exploration: Power Sources for Deep Space Probes
NSIAD-98-102: Published: May 29, 1998. Publicly Released: May 29, 1998.
Pursuant to a congressional request, GAO reviewed the use of nuclear power systems for the Cassini spacecraft and other space missions, focusing on: (1) the processes the National Aeronautics and Space Administration (NASA) used to assess the safety and environmental risks associated with the Cassini mission; (2) NASA's efforts to consider the use of a non-nuclear power source for the Cassini miss...
