STS-85

STS-85 was a Space Shuttle Discovery mission dedicated to atmospheric science, technology demonstrations, and hardware tests for future International Space Station operations. NASA lists Curtis Brown as commander, Kent Rominger as pilot, Robert Curbeam, Stephen Robinson, and N. Jan Davis as mission specialists, and Canadian Space Agency astronaut Bjarni Tryggvason as payload specialist. The mission deployed and retrieved the CRISTA-SPAS-02 free flyer, operated hitchhiker and technology payloads, tested systems related to station assembly, and carried Canadian microgravity-vibration research hardware.

Destination
Low Earth orbit at approximately 173 statute miles altitude and 51.6° inclination for free-flying CRISTA-SPAS-02 middle-atmosphere observations, Japanese Manipulator Flight Development and ISS-assembly technology tests, and TAS-01/IEH-02 hitchhiker experiments
End Date
1997-08-19
Landing Facility
Launch Site
Outcome
Successfully deployed and retrieved CRISTA-SPAS-02 after more than 200 hours of free flight and 38 atmospheric profiles, completed all TAS-1 experiments, exercised Japanese ISS robotics hardware, and performed additional atmospheric, ultraviolet, microgravity, and ISS-assembly technology work.
