India completes moon mission
On Saturday, August 29, 2009, the Indian Space Exploration Agency (ISRO) announced the final loss of communication with the orbital modules and the lunar probe Chandrayaan-1 . Three days later, the Indian authorities admitted that the lunar mission could be considered complete on this, for now there are no chances to reconnect with the device.
The orbital module Chandrayaan-1 can rotate in the Moon’s orbit for about 1000 more days, after which it will fall onto the satellite surface. Indian experts intend to appeal to colleagues from Russia and the United States with a request to help establish the location of the lost probe, because India does not have sufficiently powerful radars for this.
Chandrayaan-1 worked 312 days in orbit, made 3,400 orbits and had to hold out for over a year, but this estimate was too optimistic. In the coming days, the best scientists of the country will gather in Bangalore and try to understand the reasons for what happened.
Perhaps the loss of communication is due to a change in the orientation of the antenna to the Earth, writes New Scientist , because in July the orientation sensors (primary and secondary) failed on the orbital module. After that, he switched to orientation with the help of gyroscopes, but due to a programming error or a hardware error this system could fail.

Indian spacecraft are made by a special technology that provides maximum savings. The probe crash happened just at the time when the head of the Indian Space Agency participated in the preparations for the eighth international conference “Cheap Space Missions” in Goa. Here he gave an interview to the press.
Despite the incident, India intends to continue the space program. Earlier this year, it increased the space agency's annual budget from $ 700 million to $ 1 billion, and in 2012-2013. plans to launch the Chandrayaan-2 kit to the Moon (orbital module, landing module and lunar rover).
