PHOTOS: Inside Endeavour's engine compartment

Enclosed within a maze of work platforms, the shuttle Endeavour has spent most of its life inside one of three Orbiter Processing Facility bays at Kennedy Space Center.
When the orbiter fleet is gone from KSC, the shuttle hangars will be decommissioned and potentially handed over to commercial space firms or other NASA programs. One of the three OPFs will be used by Boeing to assemble their CST-100 commercial crew capsule, if the vehicle is selected in a competition by NASA.
Narrow corridors, steep ladders and extensive support equipment surround the shuttle inside the hangar. They give workers access to virtually every nook of the ship.
When Spaceflight Now collected these photos in early March, Endeavour was without its three main engines, yielding views inside the shuttle's aft compartment, where massive propellant lines, avionics, heavy-duty actuators, and other components reside.
Endeavour's two rear maneuvering rocket pods were also gone.
Engine nozzles and OMS pods will be added to the shuttle before it departs in September for the California Science Center in Los Angeles, where Endeavour will be put on public display.
