LDEF (Prelaunch), S0001 : Space Debris Impact Experiment, Tray D06 The Space Debris experiment consist of two (2) one third (1/3rd) tray anodized aluminum detector plates. The chromic anodize on the experiment detector plate is not an experiment requirement but is used as a major contributor to the passive thermal control of the LDEF. The green and/or pink tint seen on the detector plates is produced by the chromic anodizing process and has no impact on the experiment objectives or data analyses. The Space Debris experiment is mounted to the aluminum tray structure with nonmagnetic fasteners.
