Raiko (Japanese: 雷鼓, literally thunder drum) is a Japanese satellite which was built and operated by Tohoku and Wakayama Universities. A two-unit CubeSat, Raiko was deployed from the International Space Station on October 4, 2012, having been launched in July.
Raiko was launched aboard the Kounotori 3 spacecraft,[2] atop an H-IIB carrier rocket flying from Pad 2 of the Yoshinobu Launch Complex at the Tanegashima Space Centre. The launch occurred at 02:06 UTC on 21 July 2012.[1] Four other CubeSats were launched with Raiko; We-Wish, Niwaka, TechEdSat and F-1. The five CubeSats was delivered to the International Space Station for deployment. CubeSats were deployed from Japanese Experiment Module Kibo via the J-SSOD system on October 4, 2012 .[3][4]
Named after a Japanese god of thunder,[5] Raiko is a 2-kilogram (4.4 lb) spacecraft, which will be used for technology demonstration. It carries a camera with a fish-eye lens for Earth imaging,[6] a prototype star tracker, a deployable membrane to slow the satellite, lowering its orbit, a photographic system to measure the satellite's movement relative to the International Space Station, and a Ku-band antenna for communications and Doppler ranging experiments.[7]
We-Wish, Raiko, FITSat 1, F-1, and TechEdSat travelled to orbit aboard HTV-3.[8]
