STS-52 Patch

STS-52 Patch Mission Highlights The primary mission objectives were the deployment of the Laser Geodynamic Satellite II (LAGEOS-II) and operation of the U.S. Microgravity Payload-1 (USMP-1). LAGEOS-II, a joint effort between NASA and the Italian Space Agency (ASI), was deployed on day two and boosted into an initial elliptical orbit by ASI’s Italian Research Interim Stage (IRIS). The spacecraft’s apogee kick motor later circularized LAGEOS orbit at its operational altitude of 3,666 miles. The USMP-1, which was activated on day one, included three experiments mounted on two connected Mission Peculiar Equipment Support Structures (MPESS) mounted in the orbiter’s cargo bay. USMP-1 experiments were: Lambda Point Experiment; Materiel Pour L’Etude Des Phenomenes Interessant La Solidification Sur Et En Orbite (MEPHISTO), sponsored by the French agency Centre National d’Etudes Spatiales; and Space Acceleration Measurement System (SAMS). Secondary payloads: (1) Canadian experiment, CANEX-2, loc
