The Japan Aerospace Exploration Agency is Japan's national space agency; it conducts space, planetary, and aviation research, and leads development of rockets and satellites. It is a participant in the International Space Station: the Japanese Experiment Module (Kibō) was added to the station during Space Shuttle assembly flights in 2008. The space probe ''Akatsuki'' was launched in 2010 and achieved orbit around Venus in 2015. Japan's plans in space exploration include building a moon base and landing astronauts by 2030. In 2007, it launched lunar explorer SELENE (Selenological and Engineering Explorer) from Tanegashima Space Center. The largest lunar mission since the Apollo program, its purpose was to gather data on the moon's origin and evolution. The explorer entered a lunar orbit on October 4, 2007, and was deliberately crashed into the Moon on June 11, 2009.
