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 (ISS) on 4 October 2012, having been launched on 21 July 2012.
RAIKO was launched aboard the Kounotori 3 (HTV-3) spacecraft,[3] atop an H-IIB launch vehicle flying from pad LC-Y2 of the Yoshinobu Launch Complex at the Tanegashima Space Center. The launch occurred at 02:06:18 UTC on 21 July 2012.[1] Four other CubeSats were launched with RAIKO; WE WISH, FITSAT-1, TechEdSat-1 and F-1. The five CubeSats was delivered to the International Space Station for deployment. CubeSats were deployed from Japanese Experiment Module (JEM) Kibō via the J-SSOD system on 4 October 2012.[4][5]
Named after a Japanese god of thunder,[6] RAIKO is a 2 kg (4.4 lb) spacecraft, which was used for technology demonstration. It carries a camera with a fish-eye lens for Earth imaging,[7] 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.[8]
WE WISH, RAIKO, FITSat 1, F-1, and TechEdSat-1 travelled to orbit aboard Kounotori 3 (HTV-3).[9]
