Mission: STS-115 - 19th International Space Station Flight (12A) -
P3/P4 Truss Segments and Solar Arrays
Vehicle: Atlantis (OV-104)
Location: Orbiter Processing Facility Bay 1
Target Launch Date: Aug. 28, 2006
Launch Pad: 39B
Crew: Jett, Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

In Orbiter Processing Facility bay 1, Atlantis has been placed on a
transporter that will be used to transfer the orbiter to the Vehicle
Assembly Building. Rollover of Atlantis is currently scheduled for
Monday morning. Once in the VAB, the orbiter will be lifted into high
bay 3 for mating to the external fuel tank and solid rocket boosters.

Discovery (OV-103)

Discovery is back in Orbiter Processing Facility bay 3 following a
13-day mission to the International Space Station. The orbiter is now
being processed for its next mission, STS-116. The payload bay doors
have been opened, and thermography inspections of the nose cap and
reinforced carbon-carbon panels on the wing leading edges are under
way. The orbiter’s main engines and the orbiter boom sensor system
will be removed next week.

Endeavour (OV-105)

Powered-up system testing continues on Endeavour in Orbiter Processing
Facility bay 2 following an extensive modification period. Functional
testing of the atmosphere revitalization pressure control system is
under way. This system maintains crew module pressure during flight.
Tile-processing work continues around the external tank doors and
nose landing gear doors. Gap filler removal and replacement continues
in the high priority areas of the orbiter’s heat shield. Workers have
installed wiring for the station-shuttle power transfer system in the
midbody. Testing of the orbiter’s air to ground communication system
is complete.
