VAB - March 23,1985
PAD - March 28, 1985
April 12, 1985, 8:59:05 a.m. EST. Launch set for March 19 rescheduled to March 28 due to remanifesting of payloads from canceled mission 51-E. Delayed further due to damage to orbiter's payload bay door when facility access platform dropped. Launch April 12 delayed 55 minutes when ship entered restricted solid rocket booster recovery area. Launch Weight: 250,891 lbs.
Inclination: 28.5 degrees
Duration: Six days, 23 hours, 55 minutes, 23 seconds.
Distance: 2,889,785 miles
ET : 18/LWT-11
MLP : 1
April 19, 1985,8:54:28 a.m. EST, Runway 33, Kennedy Space Center, Fla. Rollout distance: 10,430 feet. Rollout time: 63 seconds. Extensive brake damage and blown tire during landing prompted landing of future flights at Edwards Air Force Base until implementation of nose wheel steering. Landing Weight: 198,014 lbs.
TELESAT-l (ANIK C-1) communications satellite deployed, attached to Payload Assist Module (PAM-D) motor. SYNCOM IV-3 (also known as LEASAT-3) deployed. But spacecraft sequencer failed to initiate antenna deployment, spin.up and ignition of perigee kick motor. Mission extended two days to make certain sequencer start lever in proper position. Griggs and Hoffman performed space walk to attach Flyswatter devices to remote manipulator system. Seddon engaged LEASAT lever using remote manipulator system but post deployment sequence did not begin. Other payloads: Continuous Flow Electrophoresis System (CFES) III, flying for sixth time; two Shuttle Student Involvement Program (SSIP) experiments; American Flight Echocardiograph (AFE); two Get Away Specials; Phase Partitioning Experiments (PPE); astronomy Photography verification test; medical experiments and `toys in space, an informal study of the behavior of simple toys in weightless environment, with results to be made available to school students.
