Tethered Satellite System (TSS). EURECA was deployed a day later than scheduled because of a problem with its data handling system. Seven and a half hours after deployment, the spacecraft's thrusters were fired to boost EURECA to its planned operating altitude of around 310 miles. However, thruster firing was cut to six minutes from 24 minutes because of unexpected attitude data from the spacecraft. The problem was resolved and EURECA was successfully boosted to its operational orbit on the mission's sixth day. TSS deployment also was delayed one day because of the problems with EURECA. During deployment, the satellite reached a maximum distance of only 860 feet from the orbiter instead of the planned 12.5 miles because of a jammed tether line. After numerous attempts over several days to free the tether, TSS operations were curtailed and the satellite was stowed for return to Earth. Secondary payloads included: Evaluation of Oxygen Integration with Materials/Thermal Management Processes (EOIM-III/TEMP 2A), Consortium for Materials Development in Space Complex Autonomous Payload (CONCAP II and CONCAP III), IMAX
Cargo Bay Camera (ICBC), Limited Duration Space Environment Candidate Materials Exposure (LDCE), Air Force Maui Optical Site (AMOS), Pituitary Growth Hormone Cell Function (PHCF), and Ultraviolet Plume Instrument (UVPI). Mission extended extra day to complete scientific objectives.
STS-46 marked the 150th human spaceflight to achieve orbit.
(The mission that continued with the Tethered Satellite System program was STS-75
, taking place on late February 1996.)

- 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"...
