Chang'e 1 ( /tʃæŋˈʌ/; simplified Chinese: 嫦娥一号; traditional Chinese: 嫦娥一號; pinyin: Cháng'é yī hào) was an uncrewed 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.[4] It left lunar transfer orbit on 31 October and entered lunar orbit on 5 November.[5] The first picture of the Moon was relayed on 26 November 2007.[6] 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.[7][8]
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.[2] Data gathered by Chang'e 1 was used to create an accurate and high resolution 3-D map of the lunar surface.[9] Chang'e 1 was the first lunar probe to conduct passive, multi-channel, microwave remote sensing of the Moon by using a microwave radiometer.[10]
Its sister orbital probe Chang'e 2 was launched on 1 October 2010.[11]
