MISSION: STS-84 -- 6th MIR DOCKING & SPACEHAB DM (image)

• VEHICLE: Atlantis/OV-104
• LOCATION: Orbiter Processing Facility bay 3
• TARGET KSC LAUNCH DATE/TIME: May 15 at about 4:07 a.m.
• LAUNCH WINDOW: 7-10 minutes
• TARGET KSC LANDING DATE/TIME: May 25 at about 8:27 a.m. (under review)

• CREW: Precourt, Collins, Foale, Noriega, Lu, Clervoy, Kondakova
• ORBITAL ALTITUDE and INCLINATION: 160 nautical miles/51.6 degrees

NOTE: Yesterday, Shuttle managers decided to use three additional bolts and a fabricated clamp for added strength to securely fasten each of the two "pyro cans" and plate assemblies in Atlantis’ aft compartment. In addition to the original two bolts, three new bolts will be placed into existent holes in each assembly plate.

Technicians reinstalled the "pyro cans" last night and the additional work on the assembly will be performed at the pad. Atlantis should roll over to the VAB at about 4 p.m. on Saturday and be hard mated to the external tank by late Sunday.
