It was launched by the Indian Space Research Organisation in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft using a PSLV-XL rocket, serial number C11,[1][5] on 22 October 2008 at 00:52 UTC from Satish Dhawan Space Centre, about 80 km (50 mi) north of Chennai.[6] Prime Minister Atal Bihari Vajpayee announced the project on course in his Independence Day speech on 15 August 2003.
