摘要

Solar TErrestrial RElations Observatory (STEREO) is the third mission in NASA's Solar Terrestrial Probes program, and is scheduled to launch aboard a single Delta II 7925 launch vehicle. This two-year mission will employ two nearly identical space-based observatories, one ahead of Earth in its orbit, and the other trailing behind, to provide the first-ever stereoscopic measurements to study the sun and the nature of its coronal mass ejections, or CMEs. The STEREO stacked observatory utilizes four sets of solar arrays, each of which experiences a two stage deployment on orbit. This paper illustrates material considerations in the solar array subsystem design. It first focuses on the solar array substrate, considering material coefficient of thermal expansion (CTE) concerns when choosing a substrate laminate to which to adhere the solar cells. It then explores a similar issue when choosing a substrate insert material. Next, the focus shifts to material considerations in the solar array hinge design. This design was driven not just by function, but by a host of different material considerations, ranging from mass savings to fabrication time and cost.
