STATUS REPORT : S-19950808
 
 
NASA's Space Shuttle Processing Status Report
 
 
MISSION: STS-69 -- WSF-2 & SPARTAN 201-03

VEHICLE: Endeavour/OV-105
LOCATION: Vehicle Assembly Building
TARGET LAUNCH DATE/TIME: NET late-August
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: TDB
MISSION DURATION: 10 days, 20 hours, 29 minutes
CREW SIZE: 5
ORBITAL ALTITUDE and INCLINATION: 230 statute miles/28.45 degrees

NOTE: The Space Shuttle Endeavour was returned to pad 39-A this morning with first motion from the Vehicle Assembly Building occurring at about 1:55 a.m. (Endeavour was moved off the pad to the VAB on Aug. 1 as Hurricane Erin approached the east coast of Florida.) The vehicle was spotted at the pad at about 8:30 a.m. today.

Endeavour’s launch remains on indefinite hold pending engineering analysis and repair of the solid rocket booster nozzle O-ring seals. Booster repairs are expected to begin early next week.

IN WORK TODAY:
* Pad validations
* Mechanical and electrical connections at pad

WORK SCHEDULED:
* Space shuttle main engine flight readiness test (Thursday)
* Begin set-up for solid rocket booster nozzle repairs (Thursday)

MISSION: STS-73 -- U.S. MICROGRAVITY LABORATORY-2

VEHICLE: Columbia/OV-102
LOCATION: Orbiter Processing Facility bay 3
TARGET LAUNCH DATE/TIME: Sept. 21 at 9:31 a.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: Oct. 7 at 7:25 a.m.
MISSION DURATION: 15 days, 22 hours
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 172 statute miles/39 degrees

NOTE: Engineering analysis has indicated that the no. 2 main engine on Columbia is unacceptable for flight and will be removed and replaced with an engine originally slated to fly on mission STS-74. The engine replacement has delayed Columbia’s move to the Vehicle Assembly Building by about five days.

IN WORK TODAY:
* Final payload bay cleaning
* Aft engine compartment and orbiter mid-body close-outs
* Orbiter structural inspections

KEY OPERATIONAL MILESTONES (dates are target only):
* Remove and replace space shuttle main engine no. 2 (Saturday/Sunday)
* Roll to Vehicle Assembly Building (Aug. 21)
* Roll out to pad 39-B (Aug. 26)

MISSION: STS-74 -- 2nd MIR DOCKING (Docking Module)

VEHICLE: Atlantis/OV-104
LOCATION: Orbiter Processing Facility bay 2
TARGET LAUNCH DATE/TIME: Oct. 26 at 3:08 p.m. EDT
LAUNCH WINDOW: 7 minutes
ESTIMATED MIR DOCKING DATE/TIME: Oct. 29 at 8:05 a.m. EST
TARGET KSC LANDING DATE/TIME: Nov. 3 at 11:05 a.m. EST
MISSION DURATION: 7 days, 20 hours
CREW SIZE: 5
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.6 degrees

NOTE: Preparations are underway to remove the forward reaction control system tonight and send it to the Hypergolic Maintenance Facility to replace a faulty valve.

KEY OPERATIONAL MILESTONES (dates are target only): * Install space shuttle main engines (Aug. 24-25)

DISCOVERY/OV-103 -- Pre-Orbital Maintenance Down Period

VEHICLE: Discovery/OV-103
LOCATION: Orbiter Processing Facility bay 1
TARGET DATE OF DEPARTURE FOR PALMDALE FOR OMDP: Sept. 26

NOTE: Discovery is scheduled to be delivered to Palmdale, Calif., for a nine-month Orbital Maintenance Down Period (OMDP). During this time, the vehicle will be outfitted with a 5th set of cryogenic tanks and an external airlock to support missions to the international Space Station. Discovery is scheduled to depart Kennedy Space Center via the 747 Shuttle Carrier Aircraft on or about Sept. 26.
Discovery’s next flight, the second mission to service the Hubble Space Telescope, is targeted for launch in early 1997. The space shuttle main engines are scheduled to be removed beginning Friday.

KEY OPERATIONAL MILESTONES (dates are target only):
* Remove forward reaction control system (Aug. 8)
* Remove space shuttle main engines (Aug. 11)
