'''Chang'e 1''' ({{IPAc-en|pron|tʃ|æ|ŋ|'|ʌ}}; {{zh|s=嫦娥一号|t=嫦娥一號|p=Cháng'é yī hào}}) was an [[Robotic spacecraft|uncrewed]] Chinese [[Moon|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 [[Coordinated Universal Time|UTC]] from [[Xichang Satellite Launch Center]].<ref>{{cite web|url=http://news.xinhuanet.com/english/2007-10/24/content_6937622.htm |archive-url=https://web.archive.org/web/20071025235924/http://news.xinhuanet.com/english/2007-10/24/content_6937622.htm |url-status=dead |archive-date=October 25, 2007 | title=China's 1st Moon orbiter enters Earth orbit | publisher=[[Xinhua News Agency]] | date=October 24, 2007 | access-date=2007-10-24}}</ref> It left [[lunar transfer orbit]] on 31 October and entered [[lunar orbit]] on 5 November.<ref>{{cite web |url=http://www.efluxmedia.com/news_Chinas_Change_I_Enters_Moon_Orbit_10279.html |title= China's Chang'e-I Enters Moon Orbit|website=www.efluxmedia.com |archive-url=https://web.archive.org/web/20071107081712/http://www.efluxmedia.com/news_Chinas_Change_I_Enters_Moon_Orbit_10279.html |archive-date=November 7, 2007}}</ref>

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.<ref name="deorbit">{{cite web|url=http://news.xinhuanet.com/english/2009-03/01/content_10923205.htm |archive-url=https://web.archive.org/web/20090302170937/http://news.xinhuanet.com/english/2009-03/01/content_10923205.htm |url-status=dead |archive-date=March 2, 2009 | title=China's lunar probe Chang'e-1 impacts Moon | last=Guodong | first=Du | date=2009-03-01 | publisher=Xinhua | access-date=2009-03-01}}</ref> Data gathered by Chang'e 1 was used to create an accurate and high resolution 3-D map of the lunar surface.<ref name="atimes.com">[https://web.archive.org/web/20100418193148/http://www.atimes.com/atimes/China/LD16Ad01.html "China's map leaps over the moon"] ''Asia Times''</ref> Chang'e 1 was the first lunar probe to conduct passive, multi-channel, microwave remote sensing of the Moon by using a microwave radiometer.<ref name="directory.eoportal.org">{{cite web|url=https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/chang-e-1|title=Chang'e-1 – eoPortal Directory – Satellite Missions|website=directory.eoportal.org}}</ref>
