KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
4:30 PM EDT
KSC Public Affairs Contact: Joel Wells (fax 407-867-2692)
MISSION: STS-83 -- Microgravity Science Laboratory-1
LAUNCH DATE/TIME: April 4 at 2:20:32 p.m. EST
TARGET KSC LANDING DATE/TIME: April 8 at about 2:33 p.m. EDT
MISSION DURATION: 3 days, 23 hours, 12 minutes
CREW: Halsell, Still, Voss, Thomas, Gernhardt, Linteris, Crouch
ORBITAL ALTITUDE and INCLINATION: 160 nautical miles/28.45 degrees
NOTE: Shuttle managers decided Sunday to cut short the STS-83 mission because of a problem with fuel cell No. 2. Since launch, the fuel cell displayed evidence of internal voltage degradation. Though 2 of the 3 fuel cells on Columbia are in working order, flight rules require that all three be functioning well to continue a mission. KSC is the primary landing site for Tuesday, April 8.
The solid rocket boosters were returned to Hangar AF on Sunday evening and preliminary inspections show no evidence of nozzle erosion.
