Chandrayan I: India's First Lunar Probe

Chandrayaan-1 was India's first lunar probe. 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. It was launched  from Satish Dhawan Space Centre, Sriharikota, by the PSLV C-11 on 22 October 2008. The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.
