Spacecraft

The micrometeoroid satellite Explorer XIII was the payload of Scout vehicle ST-6, and contained five experiments to obtain information regarding micrometeoroids. These experiments consisted of the following detectors: pressurized cells, steel-covered grids, copper-wire cards, cadmium-sulfide cells, and impact detectors. In addition, a series of temperature measurements were made at selected places throughout the satellite. Voltage measurements were made on test solar cells to measure degradation of the cells.
