PCSAT 2 is part of the Materials International Space Station Experiment (MISSE) using a Passive Experiment Container (PEC) to fly space environment samples to space and back. It has flown four times including a year on MIR as MEEP. It was attached to the exterior of the ISS during an EVA to expose its samples to space.

These samples are high-tech solar cells, provided by the U.S. Department of Defense, on the side of MISSE that faces the sun. On the back side, the U.S. Naval Academy has provided an Amateur Satellite Communications system similar to what it is flying on PCsat.
