Title: The 1992 Shuttle Small Payloads Symposium

Abstract

The 1992 Shuttle Small Payloads Symposium is a continuation of the Get Away Special Symposium convened from 1984 through 1988, and is proposed to continue as an annual conference. The focus of this conference is to educate potential Space Shuttle Payload Bay users as to the types of carrier systems provided and for current users to share experiment concepts. Separate abstracts have been prepared for papers in this report.

  • The flight experiment was developed to obtain benchmark atomic oxygen reactivity data and was conducted during Space Transportation System Mission 46 (STS 46), July 31 to August 7, 1992. In this paper, we present an overview of EOIM-III and the results of the materials reactivity and mass spectrometer/carousel experiments. Mass spectrometer calibration methods are discussed briefly, as a prelude to a detailed discussion of the mass spectrometric results produced during STS-46. Mass spectrometric measurements of ambient O-atom flux and fluence are in good agreement with the values calculated using the MSIS-86 model of the thermosphere as well as estimates basedmore » on the extent of O-atom reaction with Kapton polyimide. Mass spectrometric measurements of gaseous products formed by O-atom reaction with C{sup 13} labeled Kapton revealed CO, CO{sub 2}, H{sub 2}O, NO and NO{sub 2}. By operating the mass spectrometer so as to detect naturally occurring ionospheric species, we characterized the ambient ionosphere and detected the gaseous reaction products formed when ambient ions interacted with the C{sup 13} Kapton carousel sector. By direct comparison of the results of on-orbit O-atom exposures with those conducted in ground-based laboratory systems, we have demonstrated the strong translational energy dependence of O-atom reactions with a variety of polymers. A ``line-of-centers`` reactive scattering model was shown to provide a reasonably accurate description of the translational energy dependence of polymer reactions with O atoms over a three order-of-magnitude range in translational energy and a four order-of-magnitude range in reaction efficiency. Postflight studies of the polymer samples by x-ray photoelectron spectroscopy and infrared spectroscopy demonstrate that O-atom attack is confined to within 50 to 100 Angstroms of the surface.« less
