As the article on p. 4 describes, a team of Livermore researchers, in collaboration with Los Alamos and Sandia national laboratories and the Air Force Research Laboratory, is working to improve the nation’s capabilities for detecting and monitoring objects orbiting Earth to enable a more accurate assessment of whether or not orbiting objects pose a threat to any satellites. As part of this effort, experts at Livermore have been designing a comprehensive set of analysis, modeling, simulation, and visualization tools that together are called the Testbed Environment for Space Situational Awareness.
