Evolved Expendable Launch Vehicle: DOD Is Addressing Knowledge Gaps in Its New Acquisition Strategy [Reissued on August 13, 2012]
GAO-12-822: Published: Jul 26, 2012. Publicly Released: Jul 26, 2012.
The Department of Defense (DOD) has numerous efforts in progress to address the knowledge gaps and data deficiencies identified in the GAO report. Of the seven recommendations GAO made to the Secretary of Defense, two have been completely addressed. While two of GAO’s recommendations have actions underway that are expected to be completed, two recommendations need more action for completion and...
Environmental Satellites: Focused Attention Needed to Mitigate Program Risks
GAO-12-841T: Published: Jun 27, 2012. Publicly Released: Jun 27, 2012.
As requested, this statement summarizes our two reports being released today on (1) the status, plans, and risks for JPSS and (2) the status, schedule management process, and risk management process within the GOES-R program. We found that the JPSS cost and GOES-R contractor cost data were sufficiently reliable for our purposes. Further, while we found that the GOES-R schedule and management reser...
Geostationary Weather Satellites: Design Progress Made, but Schedule Uncertainty Needs to be Addressed
GAO-12-576: Published: Jun 26, 2012. Publicly Released: Jun 27, 2012.
The Geostationary Operational Environmental Satellite-R series (GOES-R) program has made progress by completing its early design milestones and is nearing the end of the design phase for its spacecraft, instrument, and ground system components. While the program continues to make progress, recent technical problems with the instruments and spacecraft, as well as a significant modification to the g...
Evolved Expendable Launch Vehicle: DOD Needs to Ensure New Acquisition Strategy is Based on Sufficient Information
GAO-11-641: Published: Sep 15, 2011. Publicly Released: Oct 17, 2011.
The Department of Defense (DOD) and the National Reconnaissance Office (NRO) plan to spend about $15 billion for launch services from fiscal year 2013 to fiscal year 2017 through DOD's Evolved Expendable Launch Vehicle (EELV) program. The program launches satellites for military, intelligence, civil, and commercial customers. In 2009, DOD and the NRO decided the program's business model needed imp...
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...
Space Acquisitions: DOD Delivering New Generations of Satellites, but Space System Acquisition Challenges Remain
GAO-11-590T: Published: May 11, 2011. Publicly Released: May 11, 2011.
Despite decades of significant investment, most of the Department of Defense's (DOD) large space acquisition programs have collectively experienced billions of dollars in cost increases, stretched schedules, and increased technical risks. Significant schedule delays of as much as 9 years have resulted in potential capability gaps in missile warning, military communications, and weather monitoring...
Commercial Space Transportation: Industry Trends and Key Issues Affecting Federal Oversight and International Competitiveness
GAO-11-629T: Published: May 5, 2011. Publicly Released: May 5, 2011.
Since GAO reported on the commercial space launch industry in 2006 and 2009, the industry has evolved and moved further toward space tourism. Commercial space tourism promises to make human space travel available to the public for the first time. In addition, the National Aeronautics and Space Administration (NASA) plans to use private companies to transport cargo, and eventually personnel, to the...
Geostationary Operational Environmental Satellites: Improvements Needed in Continuity Planning and Involvement of Key Users
GAO-10-799: Published: Sep 1, 2010. Publicly Released: Oct 1, 2010.
The Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), with the aid of the National Aeronautics and Space Administration (NASA), is to procure the next generation of geostationary operational environmental satellites, called Geostationary Operational Environmental Satellite-R (GOES-R) series. The GOES-R series is to replace the current series of satellites, which will...
Global Positioning System: Challenges in Sustaining and Upgrading Capabilities Persist
GAO-10-636: Published: Sep 15, 2010. Publicly Released: Sep 20, 2010.
The Global Positioning System (GPS) provides positioning, navigation, and timing (PNT) data to users worldwide. The U.S. Air Force, which is responsible for GPS acquisition, is in the process of modernizing the system. Last year GAO reported that it was uncertain whether the Air Force could acquire new satellites in time to maintain GPS service without interruption. GAO was asked to assess (1) the...
Next Generation Air Transportation System: FAA and NASA Have Improved Human Factors Research Coordination, but Stronger Leadership Needed
GAO-10-824: Published: Aug 6, 2010. Publicly Released: Aug 6, 2010.
To address challenges to the aviation industry's economic health and safety, the Federal Aviation Administration (FAA) is collaborating with the National Aeronautics and Space Administration (NASA) and other federal partners to plan and implement the Next Generation Air Transportation System (NextGen). NextGen will transform the current radar-based air traffic control system into a satellite-based...
