End of The Mission
The mission was launched in 22 October 2008 and expected to operate for 2 years. However, at 09.02 (UTC) on 29 August 2009 communication with the spacecraft was suddenly lost. The probe had operated for 312 days. The craft will remain in orbit for approximately another 1000 days, eventually crashing into the lunar surface.
A member of the science advisory board of Chandrayaan-1 said that it is difficult to ascertain reasons for the loss of contact. ISRO Chairman -Madhavan Nair- said that due to very high radiation, power-supply units controlling both the computer systems on board failed, snapping the communication connectivity. However, information released later showed that the power supply supplied by MDI failed due to overheating.
