NASA Human Space Exploration: Opportunity Nears to Reassess Launch Vehicle and Ground Systems Cost and Schedule
GAO-16-612: Published: Jul 27, 2016. Publicly Released: Jul 27, 2016.
The National Aeronautics and Space Administration's (NASA) new launch vehicle, the Space Launch System (SLS), has resolved some technical issues and matured its design since GAO's July 2015 report, but pressure remains on the program's limited cost and schedule reserves. This pressure, in turn, threatens its committed November 2018 launch readiness goal. The program has made progress in resolving...
Orion Multi-Purpose Crew Vehicle: Action Needed to Improve Visibility into Cost, Schedule, and Capacity to Resolve Technical Challenges
GAO-16-620: Published: Jul 27, 2016. Publicly Released: Jul 27, 2016.
The National Aeronautics and Space Administration's (NASA) Orion Multi- Purpose Crew Vehicle (Orion) program has overcome several technical challenges and made design changes to the crew capsule to reduce risk. Known challenges, however, remain—such as development of the service module and the crew capsule heatshield, among others—that could cause cost increases and schedule delays as the prog...
Space Launch System: Management Tools Should Better Track to Cost and Schedule Commitments to Adequately Monitor Increasing Risk
GAO-15-596: Published: Jul 16, 2015. Publicly Released: Jul 16, 2015.
The cost and schedule estimates for the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) program substantially complied with five of six relevant best practices, but could not be deemed fully reliable because they only partially met the sixth best practice—credibility. While an independent NASA office reviewed the estimate developed by the program and as a resul...
NASA: Human Space Exploration Programs Face Challenges
GAO-15-248T: Published: Dec 10, 2014. Publicly Released: Dec 10, 2014.
In 2014, GAO reported on a number of issues related to the National Aeronautics and Space Administration's (NASA) human exploration programs: the Space Launch System (SLS) vehicle, the Orion Multi-Purpose Crew Vehicle (Orion), and the Ground Systems Development and Operations (GSDO). For example, in July 2014, GAO found that NASA had not matched resources to requirements for the SLS program and wa...
NASA: Actions Needed to Improve Transparency and Assess Long-Term Affordability of Human Exploration Programs
GAO-14-385: Published: May 8, 2014. Publicly Released: May 8, 2014.
The scope of the National Aeronautics and Space Administration's (NASA) preliminary cost estimates for the Space Launch System (SLS), Orion Multi-Purpose Crew Vehicle (Orion), and associated ground systems encompasses only the programs' initial capabilities and does not include the long-term, life cycle costs associated with the programs or significant prior costs:The SLS estimate is based on the...
Space Acquisitions: DOD Is Overcoming Long-Standing Problems, but Faces Challenges to Ensuring Its Investments Are Optimized
GAO-13-508T: Published: Apr 24, 2013. Publicly Released: Apr 24, 2013.
Most of the Department of Defense's (DOD) major satellite programs are in mature phases of development, that is, the initial satellites have been designed, fabricated, and launched into orbit while additional satellites of the same design are being produced. For the portfolio of major satellite programs, new cost and schedule growth is not as widespread as it was in prior years, but DOD is still e...
NASA: Earned Value Management Implementation across Major Spaceflight Projects Is Uneven
GAO-13-22: Published: Nov 19, 2012. Publicly Released: Nov 19, 2012.
The National Aeronautics and Space Administration's (NASA) 10 major spaceflight projects discussed in this report have not yet fully implemented earned value management (EVM). As a result, NASA is not taking full advantage of opportunities to use an important tool that could help reduce acquisition risk. GAO assessed the 10 projects against three fundamental EVM practices that, according to GAO's...
Polar Satellites: Agencies Need to Address Potential Gaps in Weather and Climate Data Coverage
GAO-11-945T: Published: Sep 23, 2011. Publicly Released: Sep 23, 2011.
Environmental satellites provide critical data used in weather forecasting and measuring variations in climate over time. In February 2010, the White House's Office of Science and Technology Policy disbanded the National Polar-orbiting Operational Environmental Satellite System (NPOESS)--a tri-agency satellite acquisition that had encountered continuing cost, schedule, and management problems--and...
Space Acquisitions: DOD Delivering New Generations of Satellites, but Space System Acquisition Challenges Remain
GAO-11-590T: Published: May 11, 2011. Publicly Released: May 11, 2011.
Despite decades of significant investment, most of the Department of Defense's (DOD) large space acquisition programs have collectively experienced billions of dollars in cost increases, stretched schedules, and increased technical risks. Significant schedule delays of as much as 9 years have resulted in potential capability gaps in missile warning, military communications, and weather monitoring...
NASA: Medium Launch Transition Strategy Leverages Ongoing Investments but Is Not Without Risk
GAO-11-107: Published: Nov 22, 2010. Publicly Released: Nov 22, 2010.
The National Aeronautics and Space Administration (NASA) has long relied on the Delta II medium class launch vehicle to launch science missions. Delta II, however, is no longer in production, and no other vehicle in the relative cost and performance range is currently certified for NASA use. Thus, NASA faces a potential gap in the availability of medium class launch vehicles that could cause desig...
