Pcsat 2
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.
