Satellite-zombies come back to life

"Satellite-zombie", which in a few months spontaneously drifted in orbit sending signals to Earth, suddenly recovered their own inexplicable failure earlier this year.

"The most critical part of the recovery Galaxy 15 satellite was successfully passed," - said officials Intelsat, a satellite communications company owns.

Communications satellite Galaxy 15 lost contact with flight control center in April. But, to everyone’s surprise, the telecommunications broadcast packets transmitted properly. Thus, although the operators Intelsat lost the ability to control the satellite, which is powered by solar energy, Galaxy 15 continued to transmit signals that could potentially cause interference to adjacent satellites.

In the following months, the firm Intelsat worked closely with the operators of other broadcast satellites to Galaxy 15 is not affected their communication functions, which include satellite television.

But this cosmic drama came to an end.

December 23, the battery on Galaxy 15, which receives energy from solar panels, completely exhausted. After this, as has been programmed, the satellite crashes and again began to take command from the command center Intelsat.

"Currently, we have placed Galaxy 15 in safe mode, and are happy to announce that he was no longer a threat in the form of interference to adjacent satellites," - said officials Intelsat.

Galaxy 15 was out of control on April 5. The satellite, weighing nearly two tons, was adrift in space by itself. Intelsat has made several attempts to turn it off.

Manufacturer satellite company Orbital Sciences Corp. of Virginia, said that the cause of failure could serve as an intense solar storm. Intelsat provides technical investigation, but has not yet come to a final conclusion about the cause of the malfunction.

Despite the fact that the flying times Galaxy 15 points from adjacent satellites, the risk of collision with them there.

Now that the Galaxy 15 again receives commands from Earth, the company hopes to fully restore its functionality.

"After the initial diagnosis of the Galaxy 15 and stop its drift, we’ll take it to our orbit, and will assess his condition, having a large number of tests to determine the degree of functionality of all aspects of the satellite," - said in a statement.

Galaxy 15 was launched on 13 October 2005, on the European Ariane rocket. Initially, the satellite going to operate until 2020, but after his recovery, this date will be reviewed. You can always download the news ticker and be aware of all the world’s news.
