The spacecraft's apogee kick motor later circularized LAGEOS 2 orbit at its operational altitude of 5,900 km (3,700 mi).USMP-1 experiments were: Lambda Point Experiment; Matériel pour l'Étude des Phénomènes Intéressant la Solidification sur eT en Orbite (MEPHISTO),[6] sponsored by the French agency Centre National d'Études Spatiales (CNES); and Space Acceleration Measurement System (SAMS).[7] A small, specially marked satellite, the Canadian Target Assembly (CTA), was deployed on day nine, to support SVS experiments.[9] The Tank Pressure Control Experiment/Thermal Phenomena (TPCE/TP) was contained in a Getaway Special (GAS) canister in the orbiter's cargo bay.[10] Some of the ashes of Star Trek creator Gene Roddenberry were also carried aboard the orbiter for the duration of the mission.
