APL Development of Space Capabilities: 

APL Development of Space Capabilities APL has built 61 spacecraft (mostly DOD, small, with operational focus) and over 150 payloads since 1958. Provides prototypes that transition to industry TRANSIT to Midcourse Space Experiment Current space funding is primarily NASA Military Space and Civilian Space Technical Direction Agent Studies and Analyses, Tech Advice Data Analyses, Decision Aids Advanced Technology Development S&T components Sensors Implement Space Missions Build Spacecraft, incl. Integration, Test, Operations At the Pentagon, Richard Kershner explains the workings of the Transit Navigational System, on the day its first satellite is launched into orbit.
