NOTE: Mission managers today are discussing options available to launch Columbia on mission STS-73. Launch was scrubbed Saturday at the T-20 minute mark due to the failure of a Master Events Controller (MEC).
The MEC has been removed and replaced and successful retests were completed early this morning. If launch remains on schedule for Saturday, the countdown will begin at 4 a.m. Wednesday. Also, the crew is scheduled to arrive in two groups Wednesday evening.
IN WORK TODAY:
* Begin aft engine compartment close-outs
* Extended scrub turnaround operations
* Ordnance connect operations
* Off load cryogenic reactants from external tank and from onboard
* Remove and replace Master Events Controller no. 1
* Destow spacelab experiments
KEY OPERATIONAL MILESTONES:
* Close-out aft engine compartment (Wednesday)
* Begin countdown (4 a.m. Wednesday)
* STS-73 crew arrival at KSC (Wednesday evening)
* Spacelab final stowage operations (Thursday)
* Begin cryogenic loading of external tank for flight (1:26 a.m. Saturday)
MISSION: STS-74 -- 2nd MIR DOCKING (Docking Module)
LOCATION: Vehicle Assembly Building
TARGET LAUNCH DATE/TIME: Nov. 1 at 11:51 a.m. EST (NET & U/R)
LAUNCH WINDOW: 6 minutes
TARGET MIR DOCKING DATE: Nov. 4
TARGET KSC LANDING DATE/TIME: Nov. 9 at 9 a.m.
MISSION DURATION: 7 days, 21 hours
CREW SIZE: 5
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.6 degrees
NOTE: Operations continue on schedule to prepare Space Shuttle Atlantis for launch as early as Nov. 1. The vehicle was rolled to the Vehicle Assembly Building on Oct. 3 and is scheduled to be rolled out to pad 39A Wednesday, Oct. 11. First motion is set for 2 a.m. (Roll-out had been scheduled for today, but anticipated weather concerns caused managers to postpone the move.) The Shuttle interface verification test is currently in work in the VAB. Also, the Terminal Countdown Demonstration Test has been postponed from this week until Oct. 17-18.
Today, mission managers are discussing the Atlantis launch date. They will make a decision based on the firm launch date selected for Columbia. If Columbia is launched on Saturday, then Atlantis will likely be delayed about one week.
KEY OPERATIONAL MILESTONES (dates are target only):
* Move to Pad 39A (2 a.m. Oct. 11)
* Terminal Countdown Demonstration Test (Oct. 17-18)
* Flight Readiness Review (Oct. 19)
