Because of a number of key properties, anodized aluminum continues to be one of the more common spacecraft surfaces in use today. It is perhaps most commonly used because its optical properties, especially absorptivity (α) and emissivity (ɛ), can be tailored to produce a surface having excellent thermal control properties. Furthermore, since it is an oxide and is almost impervious to atomic oxygen, it is ideal for use in Low Earth Orbit (LEO) where AO attack is a major design issue. In addition to these traditional uses of the material, the recent introduction of high-voltage space power systems has caused designers to take note of the excellent insulating properties of this material. As a result, a great deal of laboratory work as well as limited space testing has been performed. We will report here on a sample of material from the Solar Array Module Plasma Interaction Experiment (SAMPIE). We believe our findings to apply generally to this material as we assess its value as a high voltage insulator in space.
