India's national space agency said communications with the country's only satellite orbiting the moon snapped Saturday and that its scientists were no longer controlling the spacecraft.
Radio contacts with Chandrayaan-1 spacecraft were abruptly lost at 0130 Saturday (2000 GMT Friday), the Indian Space Research Organization said.
The agency's monitoring unit near the southern city of Bangalore is no longer receiving data from the spacecraft, spokesman S. Satish told The Associated Press by telephone from Bangalore.
The spacecraft had completed 312 days in orbit and orbited the moon more than 3,400 times.
"We are studying the telemetry data and trying to figure out what is the problem," Satish said. The space agency had received a large volume of data from the spacecraft — which is slotted in an automatic orbit of the moon.
