The Hartebeesthoek Radio Astronomy Observatory (HartRAO) is a radio astronomy observatory, located in a natural bowl of hills at Hartebeesthoek just south of the Magaliesberg mountain range, Gauteng, South Africa, about 50 km west of Johannesburg. It is a National Research Facility run by South Africa's National Research Foundation. HartRAO was the only major radio astronomy observatory in Africa until the construction of the KAT-7 test bed for the future MeerKAT array. ==History== The observatory was originally named ''Deep Space Station 51'' and was built in 1961 by the National Aeronautics and Space Administration (NASA).〔(【引用サイトリンク】title=National Facilities - Hartebeesthoek Radio Astronomy Observatory )〕 In this role the station assisted in tracking many unmanned United States space missions, including the Ranger, Surveyor and Lunar Orbiter spacecraft (which landed on the Moon or mapped it from orbit), the Mariner missions (which explored the planets Venus and Mars) and the Pioneer missions (which measured the Sun's winds). The first Mars surface images from Mariner 4 were received at DSS 51. NASA withdrew from the station in 1975, handing it over to South Africa's Council for Scientific and Industrial Research (CSIR), who converted it to a radio astronomy observatory. In 1988 the observatory became a National Facility operated by the Foundation for Research Development (FRD); in 1999 the FRD was restructured as the National Research Foundation (NRF). , NASA continues to contract for launch tracking services on an as-needed basis, and did so for the launch of the Mars Science Laboratory on 26 November 2011.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hartebeesthoek Radio Astronomy Observatory」の詳細全文を読む スポンサード リンク
