LIMITED DURATION SPACE ENVIRONMENT CANDIDATE MATERIALS EXPOSURE (LDCE)
The primary objective of the Limited Duration Space Environment
Candidate Material Exposure (LDCE) is to introduce development
composite materials to a flux atomic oxygen atoms in low-Earth orbit.
The candidate materials-polymeric, coated polymeric, and light
metallic composites will have undergone extensive ground based
material performance testing prior to being attached to reusable test
fixtures designed for multi-mission Space Shuttle use.
The LDCE, configuration C, consists of two standard 5-cubic-foot
GAS cans with Motorized Door Assemblies (MDA's). A crewmember uses
the Autonomous Payload Control System to control the payload from the
aft flight deck. The LDCE is a simple exposure experiment that
utilizes an MDA on each can but does not contain any batteries or
fluids.
