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...
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...
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: Assessments of Selected Large-Scale Projects [Reissued on March 26, 2015]
GAO-15-320SP: Published: Mar 24, 2015. Publicly Released: Mar 24, 2015.
The National Aeronautics and Space Administration's (NASA) portfolio of major projects experienced cost and schedule growth in 2015, although that growth remains relatively low compared to historical levels. Cumulative cost growth was 2.4 percent and average schedule growth was 3 months. The growth within the past year is attributable to only a few projects. However, five projects, including the S...
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...
Polar Weather Satellites: NOAA Needs To Prepare for Near-term Data Gaps [Reissued on January 16, 2015]
GAO-15-47: Published: Dec 16, 2014. Publicly Released: Jan 15, 2015.
The Joint Polar Satellite System (JPSS) program has recently completed significant development activities and remains within its cost and schedule baselines; however, recent cost growth on key components is likely unsustainable and risks remain that could increase the potential for near-term satellite data gaps. For example, technical issues experienced while developing a key instrument have led t...
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...
Space Acquisitions: Acquisition Management Continues to Improve but Challenges Persist for Current and Future Programs
GAO-14-382T: Published: Mar 12, 2014. Publicly Released: Mar 12, 2014.
Most of the Department of Defense's (DOD) major satellite acquisition programs are in later stages of acquisition, with the initial satellites having been designed, produced, and launched into orbit while additional satellites of the same design are being produced. A few other major space programs, however, have recently experienced setbacks. For example: the Missile Defense Agency's Precision Tra...
