Launches

[edit]

It made its maiden flight on 25 April 2008, at 15:35UTC.The payload for the first launch was theTianlian I-01data relay communications satellite.The second carried theCompass-G2navigation satelliteand was conducted on 14 April 2009. The third launch was made on 16 January 2010, with theCompass-G1satellite. The fourth carrying theCompass-G3navigation satellite was launched on 2 June 2010. On 1 October 2010, it successfully launched China's second lunar probe,Chang'e 2.

An enhanced version, named Long March 3C/E, debuted during the launch ofChang'e 5-T1on 23 October 2014.[6]On 30 March 2015, theYuanzhengupper stagewas used on top of a Long March 3C launch vehicle for the first time.[7]
