NASA Space Shuttle Processing Status 18 Jun 2004

Discovery (OV-103)

Discovery’s month-long power-down period continues for its
Return to Flight mission, STS-114, to the International Space
Station. The Forward Reaction Control System was moved
Wednesday from the Hypergolic Maintenance Facility to the
Orbiter Processing Facility (OPF). Installation on the
vehicle is scheduled for tomorrow morning.

Return to Flight modifications continue, including the
orbiter boom sensor system wiring and preparations for
installation of the wing leading edge sensors. Both Freon
Coolant Loop No. 1 and 2 have been drained, and water coolant
loop No. 2 leak checks are in work.

Atlantis (OV-104)

Atlantis’ four-month power-down period continues in the OPF
in support of Return to Flight modifications, as well as
structural and baseline wire inspections. On Wednesday,
right-hand radiator No. 3 and 4 were removed from the
vehicle.

Left-hand Reinforced Carbon-Carbon panels No. 19 and 20 have
been removed to support the addition of wing leading edge
sensor instrumentation. The sensors will allow mission
managers to receive data that will help to determine any
impacts to the wing during launch.

Endeavour (OV-105)

Space Shuttle Endeavour is in its Orbiter Major Modification
period, which began last December. Electrical modifications
continue in the crew module. Wire inspections are ongoing in
the Environmental Control and Life Support System bay.

Installation of left-hand radiator No. 1 is scheduled for
today, with the No. 2 radiator scheduled for installation
early next week. Flex hose inspections continued throughout
the week.
