Mission parameters
- MassMassMass can be defined as a quantitive measure of the resistance an object has to change in its velocity.In physics, mass commonly refers to any of the following three properties of matter, which have been shown experimentally to be equivalent:...
:- Orbiter landing with payload: 97201 kilograms (214,291.5 lb)
- Payload: 8078 kilograms (17,808.9 lb)
- PerigeePerigeePerigee is the point at which an object makes its closest approach to the Earth.. Often the term is used in a broader sense to define the point in an orbit where the orbiting body is closest to the body it orbits. The opposite is the apogee, the farthest or highest point.The Greek prefix "peri"...

- InclinationInclinationInclination in general is the angle between a reference plane and another plane or axis of direction.-Orbits:The inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit...
: 28.5° - PeriodOrbital periodThe orbital period is the time taken for a given object to make one complete orbit about another object.When mentioned without further qualification in astronomy this refers to the sidereal period of an astronomical object, which is calculated with respect to the stars.There are several kinds of...

(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).
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.

Some of the ashes of Star Trek creator Gene Roddenberry were also carried aboard the orbiter for the duration of the mission.
