ISRO confirmed that the launch of India's first unmanned mission to the Moon had been postponed until the middle of October. The launch of the Chandrayaan-I lunar orbiter by ISRO was originally planned for September 19 but scientists were yet to conduct the thermo-vacuum testing of a Polar Satellite Launch Vehicle (PSLV) with the orbiter on board. ISRO chairman G. Madhavan Nair stated that the launch date would be announced 40-45 days after the completion of the thermo-vacuum testing1.
