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, remainâ€”such as development of the service module and the crew capsule heatshield, among othersâ€”that could cause cost increases and schedule delays as the prog...
GPS: Actions Needed to Address Ground System Development Problems and User Equipment Production Readiness
GAO-15-657: Published: Sep 9, 2015. Publicly Released: Sep 9, 2015.
The Air Force has experienced significant difficulties developing the Global Positioning System (GPS) next generation operational control system (OCX) and consistently overstated progress to the Office of the Secretary of Defense (OSD) compared to advisory independent assessments it received. It needs $1.1 billion and 4 years more than planned to deliver OCX due to poor acquisition decisions and a...
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 practiceâ€”credibility. While an independent NASA office reviewed the estimate developed by the program and as a result...
Space Acquisitions: Space Based Infrared System Could Benefit from Technology Insertion Planning
GAO-15-366: Published: Apr 3, 2015. Publicly Released: Apr 3, 2015.
The Air Force assessed options for replacing older technologies with newer onesâ€”called technology insertionâ€”in the Space Based Infrared System (SBIRS) geosynchronous earth orbit (GEO) satellites 5 and 6. However, the assessment was limited in the number of options it could practically consider because of timing and minimal early investment in technology planning. The Air Force assessed the fea...
Environmental Satellites: Improvements Needed in NOAA's Mitigation Strategies as It Prepares for Potential Satellite Coverage Gaps
GAO-15-386T: Published: Feb 12, 2015. Publicly Released: Feb 12, 2015.
The National Oceanic and Atmospheric Administration's (NOAA) $11.3 billion 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 schedule delays could increase the potential for a near-term satellite data gap. In addition, wh...
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...
Environmental Satellites: Focused Attention Needed to Improve Mitigation Strategies for Satellite Coverage Gaps
GAO-13-865T: Published: Sep 19, 2013. Publicly Released: Sep 19, 2013.
National Oceanic and Atmospheric Administration (NOAA) has made progress on both the Joint Polar Satellite System (JPSS) and Geostationary Operational Environment Satellite-R series (GOES-R) programs, but key challenges remain to ensure that potential gaps in satellite data are minimized or mitigated. On the JPSS program, NOAA has made noteworthy progress in using Suomi National Polar-orbiting Par...
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...
