GAO-02-403R: Published: Jun 7, 2002. Publicly Released: Jun 7, 2002.
Government, commercial, and foreign entities rely almost exclusively on information generated by the United States space surveillance network to reduce the risk of space collisions when launching and operating their respective space missions. The network is maintained and operated by the Air Force Space Command; surveillance data is processed and an unclassified portion is sent to the National Aer...
NASA: Better Mechanisms Needed for Sharing Lessons Learned
GAO-02-195: Published: Jan 30, 2002. Publicly Released: Feb 5, 2002.
The National Aeronautics and Space Administration (NASA) uses several mechanisms to capture and disseminate lessons learned. NASA has established an agency-wide Lessons Learned Information System that managers are required to review on an ongoing basis. NASA uses training, program reviews, and periodic revisions to agency policies and guidelines to communicate lessons learned. Several NASA centers...
