GAO's work has shown that the National Aeronautics and Space Administration's (NASA) large-scale projects, while producing groundbreaking research and advancing our understanding of the universe, tend to cost more and take longer to develop than planned, and are often approved without evidence of a sound business case. Although space development is complex and difficult by nature, GAO has found that inherent risks are compounded by the need for better management and oversight practices. GAO has designated NASA's acquisition management a high risk area. This report provides a snapshot of how well NASA is planning and executing its acquisition of selected large-scale projects. It also provides observations about the performance of NASA's major projects and project management, outlines steps NASA is taking to improve its acquisitions, identifies challenges that contribute to cost and schedule growth, and assesses 21 NASA projects, each with an estimated life-cycle cost of over $250 million. GAO is not making any new recommendations in this report. Instead GAO is issuing another report concurrently (GAO-11- 364R) that describes in more detail some of the issues identified in this report, such as transparency in project costs and lack of a consistent design metric, and will make recommendations to address the issues.

Work Description
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 design challenges, delays, or funding issues. GAO was asked to assess (1) NASA's and the Delta II contractor's, steps to ensure resources (budget, workforce, and facilities) are available to support safe Delta II operations through the last planned NASA flight in 2011; (2) NASA's plans and contingencies for ensuring a smooth transition from current small and medium class launch vehicles to other launch vehicles for future science missions; (3) the risks associated with NASA's planned approach to fill the medium launch capability gap; and (4) technical and programmatic implications to science missions if NASA commits to new launch vehicles before they are certified and proven. GAO identified and assessed transition plans and mitigation activities and interviewed responsible NASA and government officials. GAO recommends that NASA perform a detailed cost estimate based on knowledge gained during launch vehicle certification and adequately budget for potential additional costs. NASA concurred.
