LDEF (Postflight), S0001 : Space Debris Impact Experiment, Tray H05

The Space Debris Impact Experiment con sists of a three sixteenth (3/16) of an inch thick chromic anodized aluminum panel mounted in a three (3) inch deep LDEF experiment tray. The side of the plate exposed to the LDEF interior is painted with Chemglaze Z-306 flat black paint over a Chemglaze 9924 wash primer. The panels are attached to the aluminum tray structure with non-magnetic stainless steel fasteners. The panel coatings, a thin layer of chromic anodize facing out and the Chemglaze Z-306 black paint facing the LDEF interior, contribute significantly to thermal control of the LDEF spacecraft. The postflight photograph was taken in SAEF II at the KSC after the experiment was removed from the LDEF. A brown discoloration can be seen on the upper tray flange and a lighter discol oration on the lower tray flange not covered by the experiment tray clamp blocks. Irregular shaped tan discolorations are also visible on the experiment tray sidewall with a darker stain in the right tray corners
