Japan Station: the Japanese Experiment Module (Kibo) was added to the station during Space Shuttle assembly flights in 2008. The space probe "Akatsuki" was launched May 20, 2010, and achieved orbit around Venus on December 9, 2015. Japan's plans in space exploration include: developing the "Mercury Magnetospheric Orbiter" to be launched in 2018; and building a moon base by 2030. On September 14, 2007, it launched lunar explorer SELENE (Selenological and Engineering Explorer) on a H-IIA (Model H2A2022) carrier rocket from Tanegashima Space Center. SELENE is also known as Kaguya, after the lunar princess of "The Tale of the Bamboo Cutter".
Explorer 50 Explorer 50 Explorer 50, also known as IMP-J or IMP-8, was a NASA satellite launched to study the magnetosphere. It was the eighth and last in a series of the Interplanetary Monitoring Platform. Explorer 50 was launched on 23 October 1973 at 02:26:03 UTC, by a Delta 1604 rocket from Cape Canaveral AFS, Florida. The spacecraft functioned nominally until 7 October 2006. The satellite orbited the Earth once every 12 days, at an inclination of 28.6 degrees. Its perigee was 22 earth radii and apogee was 45 earth radii. Explorer 50 was a drum-shaped spacecraft, across and height, with propulsion
