LDEF (Postflight), S0001 : Space Debris Impact Experiment, Tray E01
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 blocks around the periphery of the experiment tray show the results of contamination and exposure to the space environment. The variation in color, from off-white along the top flange to brown at other locations, is attributed to variations in the atomic oxygen flux intensity. A surfaces exposed to a higher intensity of atomic oxygen flux will have less contamination due to the scrubbing or cleaning action that occurs when the atomic oxygen molecules impact that surface. The pink and the greenish-gray tints on the two (2) debris panels are by-product of the chromic anodize coating process and not attributed to contamination and/or exposure to the space environment. The light band along the bottom of the panels is caused by light reflecting from the tray sidewalls.
