LDEF (Postflight), AO038 : Interstellar Gas Experiment, Tray H06
LDEF (Postflight), AO038 : Interstellar Gas Experiment, Tray H06 The post landing photograph was taken from the Orbiter's cargo bay access hatch during post landing operations to prepare the Orbiter for the ferry flight from the Dryden Flight Research Center to the Kennedy Space Center. A very light contamination stain is present on the experiment tray flanges and on the most of the visible LDEF structure. The exception being a much darker stain on the structure adjacent to thermal covers that provide venting for the LDEF interior. The paint dot adjacent to the thermal cover vent area is heavily coated with the brown contamination stain while the paint dot adjacent to the center end cover plate has a very light coating. The color of the white thermal control paint on the IGE has changed and now varies from offwhite to a dark brown. The darker brown areas on the experiment baseplate, around the grid voltage cable connectors, appear to have come from contaminants flowing from inside the LDEF. A dark stain area can be seen on the tray's lower sidewall and in the upper left corner of the tray. A lighter stain coats portions of the experiment baseplate and the outside of the canister housing. A beryllium copper collector foil is clearly visible within the canister housings as are the baffles and reflected light from the fine wire mesh grid near the top of the canister housing. Due to an experi- ment system malfunction, the canister collector foils that are visible were exposed for the total mission.
