MISSION MILESTONES:
14 January 1997 ET-86 arrives on dock KSC
8 April 1997 OV-102 returns to OPF-1 following Mission-83/STS-83. MSL payload remained in teh payload bay during servicing while in the OPF. Note: Columbia pushed Endeavour out of the OPF-1 due to its unexpected early return. Endeavour was stored temporarily in the VAB HB-2. Endeavour returns to OPF-1 on 5 June.
13 May 1997 ET-86/SRB mate in VAB High Bay-1. Note: STS-83R utilized the SRB set planned for STS-85
4 June 1997 OV-102 rollover from the OPF to the VAB High Bay-1 for stacking overnight.
11 June 1997 Stack rollout to Pad 39A, 1st motion at 2:45 am, hard down at 8:00 am EDT
Not Applicable TCDT countdown dress rehearsal NOT conducted due to crew readiness following the 14 March TCDT
28 June 1997 "Call to stations" 43 hr countdown started at 3:00 pm EDT. Astronaut arrival at KSC.
1 July 1997 Launch
17 July 1997 Landing at KSC, returning to the OPF-2 that same day
