Technical Operations Support (TOPS) II. Delivery Order 0011: Summary Status of MISSE-1 and MISSE-2 Experiments and Details of Estimated Environmental Exposures for MISSE-1 and MISSE-2

The purpose of this report is to provide a description of the exposure conditions experienced by the hardware and materials specimens from the MISSE-1 (Materials International Space Station Experiment) and MISSE-2 space flight experiments. Figure 1 shows an image of MISSE-1 and MISSE-2 deployed on ISS. The nominal ram-facing sides of each experiment are visible in this image. Quantitative values are provided when possible for selected environmental factors. There are still a number of measurements that need to be complete, details of background contamination levels to be determined, and perhaps additional consideration of the effects of secondary scattering of atomic oxygen, but it is not likely that the overall conclusions and observations in this report will change significantly. An overview of this report was presented at the National Space and Missile Materials Symposium, held in Orlando, FL, on 26-30 Jun 2006.
