As with the First and Second Symposia, the abstract books for the Third Symposium will be distributed at the conference and the full-length papers will be published as a NASA Conference Publication at a later date. The First Post-Retrieval Symposium was held in Kissimmee, Florida in The Conference Publication is NASA CP First LDEF Post-Retrieval Symposium abstracts: June , , Hyatt Orlando, Kissimmee, Florida. LDEF, 69 months in space: first post-retrieval symposium. Edited by Arlene S. Levine. Washington, D.C.: National Aeronautics and Space Administration, Office of Management, Scientific and Technical Information Program. The LDEF analysis effort has been a superb training exercise, from which lessons learned need to be applied to future missions - right back to the early phases of mission planning. A year ago at the First Long Duration Exposure Facility (LDEF) Post-Retrieval Symposium, detailed measurements on trunnion sections, as well as results from 'intentional' samples (Co, Ni, In, Ta, and V) and spacecraft .

The basic intention for LDEF was to develop a retrievable platform which would provide lower-cost and more frequent access to space for the scientific and engineering community. A broad range of scientific and engineering experiments were integrated into LDEF for the first one-year mission which was deployed from Challenger (STSD) in April Cited by: 2. The assembly of the test specimens in the flight canister and in the control canister was managed by NASA's Langley Research Center (LaRC). The flight canister, shown in Figure 2, was provided with a drawer that opened and closed on command to expose the . Jun 01,  · Results are presented of the comparison between the Long Duration Exposure Facility (LDEF) Thermal Measurements Systems (THERM) recorded temperature data and the predicted values as calculated prior to the LDEF deployment. The postflight thermal model was verified and calculated temperature uncertainties were reduced to under + or - 18 F from the preflight uncertainties of + or - Cited by: 2. The systematics of induced radioactivity on the Long Duration Exposure Facility (LDEF) were studied in a wide range of materials using low level background facilities for detection of gamma rays. Approx. samples of materials processed from structural parts of the spacecraft, as well as materials from onboard experiments, were analyzed at national facilities.

Abstract. A compilation of papers presented at the First Long Duration Exposure Facility (LDEF) Post-Retrieval Symposium is presented. The papers represent the preliminary data analysis of the 57 experiments flown on the LDEF. The experiments include materials, coatings, thermal systems, power and propulsion, science (cosmic ray, interstellar Author: Arlene S. Levine.
