Above: Atlantis' aft section as viewed from the side. The reflective insulation would normally be covered by one of the shuttle's two orbital maneuvering system (OMS) engine pods. The pods are being serviced and cleaned to make them safe for Atlantis' public display.
Above: The circular openings for Atlantis' three main engines. The engines will not be reinstalled as they are being retained by NASA for future re-use with the heavy-lift Space Launch System. Instead, replica engines comprised mostly of spent nozzles will be installed in the complete engines' place.
Above: The work platforms that surround Atlantis inside Orbiter Processing Facility-2 make it difficult at times to recognize the spacecraft enveloped within. The top of Atlantis' wings can be seen just below one of the levels.
