Space Shuttle Atlantis | Payload Bay Operations

Radiator Operation

The Space Shuttle has four radiators to dissipate heat from the coolant loops - two on the inside of each of the payload bay doors. The forward radiator panels on each side can be deployed when the doors are open; the aft panels are fixed. The bay doors and radiators are operated by using the switches on panel R13L. Note that the software interface for operating the doors is not currently simulated.
