Launch 8 April 1993 @ 0129:00.043 EDT
Orbital incl: 57.00
Max alt: 302.6 km.
Orbits: 147
Dur: 9:06:08:19

Launch Info: Orbiter - Discovery 103-16 Pad 39B KSC (MLP-1) - First attempt on
6 April aborted at T-11 seconds (2:32 am) due to instrumentation problem in a high point
bleed valve on ME-1 (lead to a 2 day delay), also on 6 April an 11 hour delay due to
SLF crosswinds before RSLS abort. Landed on runway 33 KSC/SLF. 15th KSC
landing. Landing was postponed one day due to weather conditions at SLF. A second
reefing line was added to the drag chute to provide additional stability.
