Chandrayaan-1 operated for 312 days as opposed to the intended two years but the mission achieved many of its planned objectives. M3 was used to map over 95% of the lunar surface in its low-resolution Global mode, but only a small fraction in the high-resolution Target mode. After suffering from several technical issues including failure of the star sensors and poor thermal shielding, Chandrayaan-1 stopped sending radio signals at 1:30 AM IST on 29 August 2009 shortly after which, the ISRO officially declared the mission over.
