Atlantis/OV-104 (STS-74) Russian MIR-2 Docking Module
OPF Bay 2
Today the Russian MIR-2 Docking Module is being transported from the Operations and Checkout Building to OPF Bay 2 and will be installed into the payload bay of Atlantis late this afternoon. The Interface Verification Test (IVT) to verify the mechanical and electrical connections is scheduled for Monday and Tuesday next week. The orbiter docking system (ODS) was installed into the payload bay over the weekend and electrical connections are being made today. The heat shields are being installed around the three main engines.
In the Vehicle Assembly Building, the external tank is being mated to the solid rocket boosters today. For schedule reasons, a decision has been made to repair the STS-74 solid rocket booster nozzles in the VAB instead of at the launch pad.
OPF Bay 1
Work continues to deconfigure and deservice Discovery in preparation for the ferry flight to Palmdale. Discovery will be towed to the Shuttle Landing Facility on Sept. 25 for mating to the 747 Shuttle Carrier Aircraft. The ferry flight is scheduled to begin on Sept. 26.
At NASA Hangar AF on Cape Canaveral Air Station, removal of the solid rocket booster nozzles will be completed today. They will be shipped to Thiokol in Utah on Tuesday to begin inspections of the nozzle joint O-ring seals. The disassembly and analysis will take approximately two weeks.
