Missions to demonstrate small satellite deployment technologies were carried out on October 4 and 5, 2012.
This mission used the functions of the Japanese Experiment Module (JEM), known as Kibo, which is the only module with an air lock and robotic arm on the International Space Station (ISS). The goal is to establish operational procedures for deploying a small satellite into space from Kibo.
RAIKO and WE WISH were deployed on October 4 at 11:37 pm, and FITSAT-1 was deployed on October 5 at 0:44 am.
