| next_mission = Chang'e 2 | programme = Chinese Lunar Exploration Program }} Chang'e 1 (; ) was an unmanned Chinese lunar-orbiting spacecraft, part of the first phase of the Chinese Lunar Exploration Program. The spacecraft was named after the Chinese Moon goddess, Chang'e. Chang'e 1 was launched on 24 October 2007 at 10:05:04 UTC from Xichang Satellite Launch Center. It left lunar transfer orbit on 31 October and entered lunar orbit on 5 November.〔http://www.efluxmedia.com/news_Chinas_Change_I_Enters_Moon_Orbit_10279.html 〕 The first picture of the Moon was relayed on 26 November 2007. On 12 November 2008, a map of the entire lunar surface was released, produced from data collected by Chang'e 1 between November 2007 and July 2008.〔(【引用サイトリンク】 title=China publishes first map of whole lunar surface )〕〔(【引用サイトリンク】 title=Chang'E-1 Lunar Mission: An Overview and Primary Science Results )〕 The mission was scheduled to continue for a year, but was later extended and the spacecraft operated until 1 March 2009, when it was taken out of orbit. It impacted the surface of the Moon at 08:13 UTC. Data gathered by Chang'e 1 was able to create the most accurate and highest resolution 3-D map ever created of the lunar surface.〔("China's map leaps over the moon" ) ''Asia Times''〕 Chang'e 1 is the first lunar probe to conduct passive, multi-channel, microwave remote sensing of the Moon by using a microwave radiator.〔("Chang'e - 1 (Lunar-1 Mission of China)" )〕 Its sister orbital probe Chang'e 2 was launched on 1 October 2010. == Objectives == The Chang'e 1 mission had four major goals:〔〔(【引用サイトリンク】 Chang'e-1 - new mission to Moon lifts off )〕 # Obtaining three-dimensional images of the landforms and geological structures of the lunar surface, so as to provide a reference for planned future soft landings. The orbit of Chang'e 1 around the Moon was designed to provide complete coverage, including areas near the north and south poles not covered by previous missions. # Analysing and mapping the abundance and distribution of various chemical elements on the lunar surface as part of an evaluation of potentially useful resources on the Moon. China hopes to extend the number of elements studied to 14 (potassium (K), thorium (Th), uranium (U), oxygen (O), silicon (Si), magnesium (Mg), aluminium (Al), calcium (Ca), tellurium (Te), titanium (Ti), sodium (Na), manganese (Mn), chromium (Cr), and lanthanum (La)),〔 compared with the 10 elements (K, U, Th, Fe (iron), Ti, O, Si, Al, Mg, and Ca) previously probed by NASA's Lunar Prospector. # Probing the features of the lunar soil and assessing its depth, as well as the amount of helium-3 (³He) present.〔 # Probing the space environment between 40,000 km and 400,000 km from the Earth, recording data on the solar wind and studying the impact of solar activity on the Earth and the Moon. In addition, the lunar probe engineering system, composed of five major systems – the satellite system, the launch vehicle system, the launch site system, the monitoring and control system and the ground application system – accomplished five goals: * Researching, developing and launching China's first lunar probe * Mastering the basic technology of placing satellites in lunar orbit * Conducting China's first scientific exploration of the Moon * Initially forming a lunar probe space engineering system * Accumulating experience for the later phases of China's lunar exploration program 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「Chang'e 1」の詳細全文を読む スポンサード リンク
