SEEDS-2

The Space Engineering EDucation Satellite 2 (SEEDS-2) is a Japanese amateur CubeSat picosatellite, built and operated by Nihon University. It was launched by the Indian Space Research Organisation, aboard a PSLV rocket, on 28 April 2008. It was built to replace the SEEDS satellite, which was lost in a launch failure on a Dnepr rocket in July 2006.

It carries a number of sensors to investigate the environment of space, and its own status. It also contains a voice transmitter, intended to play back messages to amateur radio operators.
