Launch from Cape Canaveral (
KSC);
landing on Cape Canaveral (
KSC). The launch was originally planned for mid
October 1992. Technical problems with one of the main engines forced the
NASA to replace it. This work was done on the launch
pad.
Primary mission objectives were 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 2 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, 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;
Matériel Pour L'Etude Des Phénomènes Intéressant La
Solidification Sur Et En Orbite (MEPHISTO), sponsored by the French agency
Centre National d'Études Spatiales; and Space Acceleration Measurement
System (SAMS), which had already flown in several mission
before.
Secondary payloads: (1) Canadian experiment,
CANEX-2,
located in both the orbiter's cargo bay and middeck and which consisted of
Space Vision System (SVS); Materials Exposure in Low-Earth Orbit (MELEO);
Queen's University Experiment in Liquid-Metal Diffusion (QUELD); Phase
Partitioning in Liquids (PARLIQ); Sun Photospectrometre Earth Atmosphere
Measurement-2 (SPEAM-2); Orbiter Glow-2 (OGLOW-2); and Space Adaptation Tests
and Observations (SATO). A small, specially marked satellite, the Canadian
Target Assembly, was deployed on day nine, to support SVS experiments. (2) ASP,
featuring three independent sensors mounted on a Hitchhiker plate in the cargo
bay -, Modular Star Sensor (MOSS), Yaw Earth Sensor (YES) and Low Altitude
Conical Earth Sensor (LACES), all provided by the European Space
Agency.
Other middeck payloads: Commercial Materials Dispersion
Apparatus Instrument Technology Associates Experiments; Commercial Protein
Crystal Growth experiment; Chemical Vapor Transport Experiment; Heat Pipe
Performance Experiment; Physiological Systems Experiment (involving 12
rodents); and Shuttle Plume Impingement Experiment. The orbiter also was used
as a reference point for calibrating an Ultraviolet Plume Instrument on an
orbiting Strategic Defense Initiative Organization satellite.
