Behind the STP-1 is the Air Force Program 675 (AFP-675) experiment support structure (ESS) with ESS tape recorders (left), Uniformly Redundant Array (URA) (front),and Cryogenic Infrared Radiance Instrumentation for Shuttle 1A (CIRRIS-1A) (center back) visible. The ESS pallet power distribution system thermal covering (gold-colored) is visible at the bottom. AFP-675 is a Department of Defense (DOD)-sponsored collection of experiments whose objective is to gather data on the Earth's atmosphere (aurora, Earth limb, and airglow), celestial objects, and the environment in and around the PLB.
