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 {{convert|2|kg|adj=on}} 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]References1. ^1 {{cite web|url=http://www.nasaspaceflight.com/2012/07/japanese-h-iib-launch-htv-3-international-space-station/|title=Japanese H-IIB launches HTV-3 to the International Space Station|first=Chris|last=Bergin|publisher=NASASpaceflight.com|date=20 July 2012|accessdate=21 July 2012}} 2. ^{{cite web|url=http://www.spaceflightnow.com/h2b/htv3/launch.html|title=Japan successfully launches its freighter to space station|first=William|last=Harwood|date=20 July 2012|accessdate=21 July 2012|publisher=Spaceflight Now}} 3. ^{{cite web|url=http://www.wakayama-u.ac.jp/ifes/news/20110615.html|title=2011年6月15日 ISSからの小型衛星放出実証ミッションに採択されました |date=15 July 2012|publisher=Institute for Education in Space|accessdate=21 July 2012}} 4. ^{{cite web |url=http://news.mynavi.jp/articles/2012/01/25/j-ssod/index.html |title= JAXA、宇宙ステーションから超小型衛星を放出できる装置をプレス公開| publisher=mynavi.jp| author= 大塚実 |language=Japanese | date= 25 January 2012 | accessdate= 21 July 2012}} 5. ^{{cite web|url=http://www.astro.mech.tohoku.ac.jp/RAIKO/|title=国際宇宙ステーション放出衛星「RAIKO」（雷鼓）|publisher=Tohoku University|accessdate=21 July 2012}} 6. ^{{cite web|url=http://www.tohoku.ac.jp/english/2012/06/news20120625-03.html|title=The development of a microsatellite (RAIKO) is completed and delivered to JAXA|publisher=Tohoku University|date=25 June 2012|accessdate=21 July 2012}} 7. ^{{cite web|url=http://space.skyrocket.de/doc_sdat/raiko.htm|title=Raiko|first=Gunter|last=Krebs|work=Gunter's Space Page|accessdate=21 July 2012}} 8. ^We-Wish External links{{Portal|Japan|Spaceflight}}
