Global Positioning System: Observations on Quarterly Reports from the Air Force
GAO-17-162R: Published: Oct 17, 2016. Publicly Released: Oct 17, 2016.
The Air Force’s first Global Positioning System (GPS) quarterly report provided important information on some of the programs’ efforts and details about its full and long-term cost, schedule, performance, testing, and risk. The report included individual program schedules and costs for some programs. However, it did not include an integrated master schedule—key information needed to demonstr...
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...
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...
James Webb Space Telescope: Project Facing Increased Schedule Risk with Significant Work Remaining
GAO-15-483T: Published: Mar 24, 2015. Publicly Released: Mar 24, 2015.
James Webb Space Telescope (JWST) project officials report that the effort remains on track toward the schedule and budget established in 2011. However, the project is now in the early stages of its extensive integration and testing period. Maintaining as much schedule reserve as possible during this phase is critical to resolve challenges that will likely surface and negatively impact the schedul...
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...
James Webb Space Telescope: Project Meeting Commitments but Current Technical, Cost, and Schedule Challenges Could Affect Continued Progress
GAO-14-72: Published: Jan 8, 2014. Publicly Released: Jan 8, 2014.
The James Webb Space Telescope (JWST) project is generally executing to its September 2011 revised cost and schedule baseline; however, several challenges remain that could affect continued progress. The National Aeronautics and Space Administration (NASA) has requested funding that is in line with the rebaseline and the project is maintaining 14 months of schedule reserve prior to its launch date...
Global Positioning System: A Comprehensive Assessment of Potential Options and Related Costs is Needed
GAO-13-729: Published: Sep 9, 2013. Publicly Released: Sep 9, 2013.
GAO found the Air Force, the military branch responsible for Global Positioning System (GPS) acquisition, in its report on Lower Cost Solutions for Providing Global Positioning System Capability, broadly addressed all four congressional requirements--system capability, implementation approaches, technical and programmatic risks, and estimated costs--for each option presented for the space segment...
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...
Additional Cost Transparency and Design Criteria Needed for National Aeronautics and Space Administration (NASA) Projects
GAO-11-364R: Published: Mar 3, 2011. Publicly Released: Mar 3, 2011.
GAO published its third annual assessment of selected large-scale NASA projects. During this assessment we identified several issues that merit NASA's management attention. The federal government faces real fiscal limitations and will have to make difficult choices about upcoming priorities. This reality makes it more important than ever that NASA manage its programs and projects as efficiently an...
