Losat-X (Low Altitude Satellite Experiment), built for SDIO, was to gather multi-spectral data on ground-launched rocket plumes and the space environment. It also was used for development and testing of other technologies (wide field-of-view star camera).
Originally planned to be launched with LACE and RME, Losat-X was delayed and finally launched with GPS-2A 2. The spacecraft was sidemounted on the second stage of the Delta-7925 launch vehicle and was spring-ejected after the deployment of the third stage.
Planned for a three-month lifetime, the main objectives were accomplished during the first day in orbit, but Losat-X was lost due to a failure in the command receiver after nine days.
