The Chinese Lunar Exploration Program (CLEP) (), also known as the Chang'e program after the Chinese moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA). The program incorporates lunar orbiters, landers, rovers and sample return spacecraft, launched using Long March rockets. Launches and flights are monitored by a Telemetry, Tracking and Command (TT&C) system, which uses radio antennas in Beijing and antennas in Kunming, Shanghai and Ürümqi to form a VLBI antenna.〔 (“嫦娥奔月”地面主干工程基本完成 云南天文台巨型射电追踪望远镜年底投入使用 )〕〔(巨型望远镜送“嫦娥”飞月-望远镜,嫦娥-北方网-科技无限 )〕 A proprietary ground application system is responsible for downlink data reception. Ouyang Ziyuan, a geologist and chemical cosmologist, was among the first to advocate the exploitation not only of known lunar reserves of metals such as titanium, but also of helium-3, an ideal fuel for future nuclear fusion power plants. He currently serves as the chief scientist of the Chinese Lunar Exploration Program. Another scientist, Sun Jiadong, was assigned as the general designer, while scientist Sun Zezhou was assigned as the deputy general designer. The leading program manager is Luan Enjie. The first spacecraft of the program, the Chang'e 1 lunar orbiter, was launched from Xichang Satellite Launch Center on 24 October 2007, having been delayed from the initial planned date of 17–19 April 2007.〔 (阅读文章 )〕 A second orbiter, Chang'e 2, was launched on 1 October 2010. Chang'e 3, which includes a lander and rover, was launched on 1 December 2013 and successfully soft-landed on the Moon on 14 December 2013. It will be followed by a sample return mission, Chang'e 5 scheduled for 2017.〔(【引用サイトリンク】title=China’s Unmanned Moon Mission To Bring Back Lunar Soil To Earth )〕 As indicated by the official insignia, in the shape of a calligraphic nascent lunar crescent with two human footprints at its center reminiscent of the Chinese character for ″moon″, the ultimate objective of the program is to pave the way for a manned mission to the Moon. Such a mission may occur in 2025–2030. ==Program structure== The Chinese Lunar Exploration Program is divided into three main operational phases, with each mission serving as a technology demonstrator in preparation for future missions. 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「Chinese Lunar Exploration Program」の詳細全文を読む スポンサード リンク
