NASA Commercial Crew Program: Schedule Pressure Increases as Contractors Delay Key Events
GAO-17-137: Published: Feb 16, 2017. Publicly Released: Feb 16, 2017.
Both of the Commercial Crew Program's contractors have made progress developing their crew transportation systems, but both also have aggressive development schedules that are increasingly under pressure. The two contractors—Boeing and Space Exploration Technologies, Corp. (SpaceX)—are developing transportation systems that must meet the National Aeronautics and Space Administration's (NASA) s...
James Webb Space Telescope: Project Meeting Cost and Schedule Commitments but Continues to Use Reserves to Address Challenges
GAO-17-71: Published: Dec 7, 2016. Publicly Released: Dec 7, 2016.
The National Aeronautics and Space Administration's (NASA) James Webb Space Telescope (JWST) project is still operating within its committed schedule while in its riskiest phase of development, integration and test. Most hardware deliveries and two of five major integration and test efforts have been completed. Two other integration and test efforts are underway, with the final effort to begin in...
Commercial Space: FAA Should Examine How to Appropriately Regulate Space Support Vehicles
GAO-17-100: Published: Nov 25, 2016. Publicly Released: Nov 25, 2016.
Company officials GAO interviewed identified potential uses for “space support vehicles”—which include a variety of aircraft from high-performance jets to balloons and the aircraft portion of a hybrid launch systems (a vehicle that contains elements of both an aircraft and a rocket-powered launch vehicle)—but the size of the market for these uses is unclear. Company officials said they pla...
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...
NASA: Assessments of Major Projects
GAO-16-309SP: Published: Mar 30, 2016. Publicly Released: Mar 30, 2016.
The cost and schedule performance of the National Aeronautics and Space Administration's (NASA) portfolio of major projects has improved over the past 5 years, and most current projects are adhering to their committed cost and schedule baselines. Over the last 2 years, eight projects in the portfolio established cost and schedule baselines. As the figure below shows, as the average age of the port...
NASA: Preliminary Observations on Major Acquisition Projects and Management Challenges
GAO-16-461T: Published: Feb 25, 2016. Publicly Released: Feb 25, 2016.
GAO's ongoing work indicates that the National Aeronautics and Space Administration (NASA) has made progress over the past 5 years in a number of key acquisition management areas, but it faces significant risks in some of its major projects. On the positive side, the cost and schedule performance of NASA's portfolio of major projects in development has improved and most current projects are adheri...
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...
International Space Station: Challenges to Increased Utilization May Affect Return on Investment
GAO-15-722T: Published: Jul 10, 2015. Publicly Released: Jul 10, 2015.
Based on GAO analysis of the National Aeronautics and Space Administration's (NASA) fiscal year 2016 budget estimate, the agency anticipates that the costs to operate, sustain, perform research, and provide crew and cargo transportation to the International Space Station (ISS) are projected to increase by almost $1 billion—or almost 53 percent—from fiscal year 2015 to fiscal year 2020 when the...
International Space Station: Measurable Performance Targets and Documentation Needed to Better Assess Management of National Laboratory
GAO-15-397: Published: Apr 27, 2015. Publicly Released: May 27, 2015.
The Center for the Advancement of Science in Space (CASIS), manager of the International Space Station (ISS) National Laboratory, has taken steps to fulfill its management responsibilities contained in its cooperative agreement with the National Aeronautics and Space Administration (NASA), and has initiated the activities required by the NASA Authorization Act of 2010. GAO found that CASIS impleme...
