Mitsuba had two major missions. The first mission was to study how
semiconductor parts for use on the ground degrade in space. While most of the semiconductor parts typically used in nanosatellites are
commercial off-the-shelf products, such products are not certified for
radiation resistance. The semiconductor parts are tested on the ground to see whether it can still function after receiving a
absorbed dose of around 100
gray of radiation. If it passes the test, the product will be selected to fly to space. Mitsuba would have validated whether 100 gray is too weak or too strong when compared to the amount of radiation the parts will actually receive in space. The second mission was to test
USB devices in space. A general purpose USB device without space-grade modifications would have been brought to orbit to test whether it functioned properly. Mitsuba carried a USB
spectrum analyzer inside, and would have experimented whether the device could measure spectrums while in space as it would on Earth. ==See also==
