 device that is used on HST to provide pointing information for the spacecraft and is used as a scientific instrument for astrometric science. The Solid State Recorder (SSR) will replace one of HST's current reel-to-reel tape recorders. The SSR provides much more flexibility than a reel-to-reel recorder and can store ten times more data. One of Hubble's four Reaction Wheel Assemblies (RWA) will be replaced with a refurbished spare. The RWA is part of Hubble's Pointing Control Subsystem. The RWAs use spin momentum to move the telescope into position. The wheels also maintain the spacecraft in a stable position. The wheel axes are oriented so that the telescope can provide science with only three wheels operating, if required.

Mission Results

STS-82 demonstrated anew the capability of the Space Shuttle to service orbiting spacecraft as well as the benefits of human spaceflight

 in December 1993. Hawley, who originally deployed the telescope, operated the orbiter Remote Manipulator System arm on STS-82 to retrieve HST for second servicing at 3:34 am EST, 13 Feb., and positioned it in payload bay less than half an hour later.

Relying on more than 150 tools and crew aids, Lee and Smith performed EVAs 1, 3 and 5, and Harbaugh and Tanner did EVAs 2 and 4. EVA 1 began at 11:34 pm EST, 13 February, and lasted six hours, 42 minutes. One of Hubble's solar arrays was unexpectedly disturbed by gust of air from Discovery's airlock when it was depressurized, but was not damaged.

 (NICMOS), respectively. STIS expected to shed further light on supermassive black holes. NICMOS features more capable infrared detectors and will give astronomers their first clear view of the universe at near infrared wavelengths between 0.8 and 2.5 micrometers.

EVA 2 began at 10:25 pm, 14 February, and lasted seven hours, 27 minutes. Harbaugh and Tanner replaced a degraded Fine Guidance Sensor and a failed Engineering and Science Tape Recorder with new spares. Also installed a new unit called the Optical Control Electronics Enhancement Kit, which will further increase the capability of the Fine Guidance Sensor. During this EVA astronauts noted cracking and wear on thermal insulation on side of telescope facing sun and in the direction of travel.

EVA 3 began at 9:53 pm, 15 February, and lasted seven hours, 11 minutes. Lee and Smith removed and replaced a Data Interface Unit on Hubble, as well as an old reel-to-reel- style Engineering and Science Tape Recorder with a new digital Solid State Recorder (SSR) that will allow simultaneous recording and playback of data. Also changed out one of four Reaction Wheel Assembly units that use spin momentum to move telescope toward a target and maintain it in a stable position. After this EVA, mission managers decided to add EVA 5 to repair the thermal insulation on HST.

EVA 4 began at 10:45 pm, 16 February, and lasted six hours, 34 minutes. Harbaugh and Tanner replaced a Solar Array Drive Electronics package which controls the positioning of Hubble's solar arrays. Also replaced covers over Hubble's magnetometers and placed thermal blankets of multi-layer material over two areas of degraded insulation around the light shield portion of the telescope just below the top of the observatory. Meanwhile, inside Discovery Horowitz and Lee worked on the middeck to fabricate new insulation blankets for HST.

Final space walk, EVA 5, lasted five hours, 17 minutes. Lee and Smith attached several thermal insulation blankets to three equipment compartments at the top of the Support Systems Module section of the telescope which contain key data processing, electronics and scientific instrument telemetry packages. STS-82 EVA total of 33 hours, 11 minutes is about two hours shy of total EVA time recorded on first servicing mission.

Discovery's maneuvering jets fired several times during mission to reboost telescope's orbit by eight nautical miles. Hubble redeployed on 19 Feb. at 1:41 am and is now operating at the highest altitude it has ever flown, a 335 nautical miles (620.4 km) by 321 nautical miles (594.5 km) orbit. Initial checkout of new instruments and equipment during mission showed all were performing nominally. Calibration of two new science instruments was to take place over a period of several weeks with first images and data anticipated in about eight to 10 weeks.
