He is back from the international space station ISS after 18 months floating around in Space! The social robot Kirobo’s responsibility on board was speaking with the astronauts!

The space ship has been away from the earth since it was shot up in August 2013! Here is a video where you can see Kirobo and Koichi speaking with each other!
