KSC-97pc350

KENNEDY SPACE CENTER, Fla. -- Under the cover of darkness, the Space Shuttle orbiter Discovery glides in for a landing on Runway 15 at KSC's Shuttle Landing Facility at the conclusion of a 10-day mission to service the orbiting Hubble Space Telescope (HST). New runway centerline lights provide an additional visual aid for the nighttime landings. STS-82 is the ninth Shuttle nighttime landing, and the fourth nighttime landing at KSC. The seven-member crew performed a record-tying five back-to-back extravehicular activities (EVAs) or spacewalks to service the telescope, which has been in orbit for nearly seven years. Two new scientific instruments were installed, replacing two outdated instruments. Five spacewalks also were performed on the first servicing mission, STS-61, in December 1993. Only four spacewalks were scheduled for STS-82, but a fifth one was added during the flight to install several thermal blankets over some aging insulation covering three HST compartments containing key data processing, electronics and scientific instrument telemetry packages. Crew members are Mission Commander Kenneth D. Bowersox, Pilot Scott J. "Doc" Horowitz, Payload Commander Mark C. Lee, and Mission Specialists Steven L. Smith, Gregory J. Harbaugh, Joseph R. "Joe" Tanner and Steven A. Hawley. STS-82 was the 82nd Space Shuttle flight and the second mission of 1997
