Orbiter Integration

Once the payloads have been installed in the Orbiter payload bay by the PGHM, the cables to the Orbiter are mated and interface verification testing is begun. All testing of payloads in the payload bay is done from one of the firing rooms at the Launch Control Center (LCC). It is possible for payload personnel to monitor these tests from the Launch Processing System (LPS) consoles in the LCC or the payload user's ground checkout station consoles located in the PPF (if prearranged). The LPS hardware and software allows monitoring of only the Orbiter General Purpose Computer payload information telemetered through Orbiter system.

If it is required, an end-to-end test will be performed in the payload bay as an optional service. This includes the Johnson Space Center Mission Control Center, the user's Payload Operations Control Center (POCC), and any other centers required to support the mission. Once payload testing has been completed, the final ordnance connections are mad, safing completed, and closeouts for flight performed.

The payload bay doors are closed and any requirements for late servicing, such as battery charging, will be accomplished through the Orbiter umbilicals as part of the total Shuttle countdown.

The other elements of the STS are now readied and the Shuttle is launched.
