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.
