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".
Flight dynamics (spacecraft) given above in Powered flight: A simple lunar trajectory stays in one plane, resulting in lunar flyby or orbit within a small range of inclination to the Moon's equator. This also permits a "free return", in which the spacecraft would return to the appropriate position for reentry into the Earth's atmosphere if it were not injected into lunar orbit. Relatively small velocity changes are usually required to correct for trajectory errors. Such a trajectory was used for the Apollo 8, Apollo 10, Apollo 11, and Apollo 12 manned lunar missions. Greater flexibility in lunar orbital or landing site coverage (at
