LDEF (Postflight), S0001 : Space Debris Impact Experiment, Tray E04
The postflight photograph was taken in the SAEF II at KSC prior to experiment removal from the LDEF. The originally white paint dot on clamp block at the center of the left tray flange and at the right end of the upper tray flange are dark brown. Since this tray is located adjacent to the LDEF's trailing edge, very little, if any, contamination has been cleaned away by atomic oxygen impacts. The greenish-gray and pink tints on the two (2) debris panels are a by-product of the chromic anodize coating process and not attributed to contamination and/or exposure to the space environment. The finger prints along the bottom edge of the panels that was observed in the flight photograph are still visible. Those seen previously along the top edges have been washed out by the lighting. The light band along the sides and across the top of the panels is caused by light reflecting from the tray sidewalls.
