		NiH2 Battery A lightweight NiH2 Common Pressure Vessel (CPV) battery (15 Ampere-Hour, 22 cell), developed under a Cooperative Research and Development Agreement (CRADA) between the NRL and Johnson Controls, Inc., provided energy storage for use during eclipses and high power usage activities. The Clementine mission was the first space flight use of a single container NiH2 CPV battery. GaAs/Ge Solar Arrays The solar arrays, developed by Applied Solar Energy Corporation, provided the power generation for all spacecraft subsystems. The solar arrays were the thinnest (0.14 mm) GaAs/Ge solar cells flown to date. The spacecraft had two "wings" of solar arrays. They were independently gimbaled in a single axis and could track the Sun autonomously. The solar array power generated depended upon the mission phase. During LEO and the TTI burn, the solar arrays were stowed at varying angles to the Sun and provided 160 W to 268 W of power. After solar array deployment following the TTI burn, they autonomously tracked the sun and provided up to 360 W of power.
