      Thermal Cycling of Mir Cooperative Solar Array (MCSA) Test Panels The Mir Cooperative Solar Array (MCSA) project was a joint US/Russian effort to build a photovoltaic (PV) solar array and deliver it to the Russian space station Mir. The MCSA is currently being used to increase the electrical power on Mir and provide PV array performance data in support of Phase 1 of the . the Mir Environmental Effects Payload (MEEP) utilized hardware returned from low-Earth-orbit (LEO) to study and measure space and spacecraft-induced environmental effects. A section of a solar array tetm_ted fi'om the Mir space station has also been extensively studied for power degradation, micrometeoroid, and contamination effects. "Research.

    "The Solar Cell Array Design Handbook is written at a practicing engineering level and provides a comprehensive compilation of explanatory notes, design practices, analytical models, solar cell characteristics, and material properties data of interest to personnel engaged in solar cell array performance specifications, hardware design, analysis Author: California Hans S. Rauschenbach with Jet Propulsion Laboratory, California Institute of Technology - Pasadena. This solar tracker study is similar to our project. In project, we use 4 part in reference system,but instead of LDR, we use solar cell for each platform. Figure 1. Tracking Sensor Internal Design. 5. Figure 2.

Silicone contamination on the back surface of the solar array optical solar reflectors retrieved from Mir are shown in figure 8. As can be seen from figure 8, the silica contaminant is highly visible in contrast to the area which was cleaned by tape peeling (where the contaminant readily separated from the surface of the optical solar reflector).
