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...
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...
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...
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...
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...
Geostationary Weather Satellites: Progress Made, but Weaknesses in Scheduling, Contingency Planning, and Communicating with Users Need to Be Addressed
GAO-13-597: Published: Sep 9, 2013. Publicly Released: Sep 19, 2013.
The National Oceanic and Atmospheric Administration (NOAA) has completed the design of its Geostationary Operational Environmental Satellite-R (GOES-R) series and made progress in building flight and ground components. While the program reports that it is on track to stay within its $10.9 billion life cycle cost estimate, it has not reported key information on reserve funds to senior management. A...
Space: Defense and Civilian Agencies Request Significant Funding for Launch-Related Activities
GAO-13-802R: Published: Sep 9, 2013. Publicly Released: Sep 9, 2013.
Defense and civilian government agencies together expect to require significant funding--nearly $44 billion in "then-year" dollars that factor in anticipated future inflation--for launch-related activities from fiscal years 2014 through 2018. Procurement funding represents about $28 billion--some 65 percent--of this total, while Research, Development, Test, and Evaluation (RDT&E) constitutes appro...
NASA: Significant Challenges Remain for Access, Use, and Sustainment of the International Space Station
GAO-12-587T: Published: Mar 28, 2012. Publicly Released: Mar 28, 2012.
NASA plans to use international partner and new domestic commercial launch vehicles to access, utilize, and sustain the International Space Station from 2012 through 2020. However, the agency faces challenges in transporting cargo and crew to the ISS as well as ensuring the station is fully utilized. NASAs decision to rely on the new commercial vehicles to transport cargo starting in 2012 an...
International Space Station: Approaches for Ensuring Utilization through 2020 Are Reasonable but Should Be Revisited as NASA Gains More Knowledge of On-Orbit Performance
GAO-12-162: Published: Dec 15, 2011. Publicly Released: Dec 15, 2011.
NASAs approach to determining, obtaining, and delivering necessary spare parts to the ISS is reasonable to ensure continued utilization of the station through 2020. The statistical process and methodology being used to determine the expected lifetimes of replacement units is a sound and commonly accepted approach within the risk assessment community that considers both manufacturers pr...
Key Controls NASA Employs to Guide Use and Management of Funded Space Act Agreements Are Generally Sufficient, but Some Could Be Strengthened and Clarified
GAO-12-230R: Published: Nov 17, 2011. Publicly Released: Nov 17, 2011.
In the National Aeronautics and Space Act of 1958, Congress granted the National Aeronautics and Space Administration (NASA) authority to enter into transactions other than contracts, leases, and cooperative agreements; this gave the agency greater flexibility in achieving its mission. NASA uses its other transaction authority through three kinds of instruments known as Space Act agreements. Speci...
