Advanced Russian Communications Satellite Lost in Rocket Failure - Video

An advanced Russian communications satellite was destroyed Thursday (May 15) when its Proton rocket booster failed minutes after liftoff from the Baikonur Cosmodrome in Kazakhstan.

The Express AM4R spacecraft, worth approximately $200 million and built by EADS Astrium, was supposed to begin a 15-year mission beaming radio, television, broadband Internet and telephone services across Russia and neighbouring countries.

But a few minutes after the 12,720-pound (5,770-kilogram) Express AM4R satellite launched from Baikonur, Russia's primary space base, its Proton rocket ran into a problem.

The failure occurred during the third stage of the Proton's ascent into orbit, according to a statement by the Khrunichev State Research and Production Space Center, the Moscow-based manufacturer of the Proton launcher.

An announcer declared an emergency during a live webcast of the launch, and Khrunichev's statement also described the incident as an "emergency situation."

Khrunichev said experts were analyzing telemetry to determine the cause of the failure.

A report by Interfax said debris from the rocket may have fallen in the Altai or Amur regions of Russia's Far East.

Spewing a brilliant flame of blue exhaust, the 19-story Proton rocket lifted off at 2142 GMT (5:42 p.m. EDT) to start a nine-hour flight to deploy the powerful European-built Express AM4R telecommunications satellite for Russian government and commercial customers.

The launch was at 3:42 a.m. local time at Baikonur.

The hydrazine-fueled rocket disappeared from the view of a ground-based tracking camera a few minutes later, with no visible signs of any trouble.

But a problem occurred about 545 seconds, or about 9 minutes, after liftoff, according to a report by the semi-official Itar-Tass news agency.

Another report by the Interfax media service said the time of the failure was about 500 seconds after launch.

Both of the times reported for the anomaly occurred during the firing of the Proton rocket's third stage, which is powered by an RD-0213 main engine generating 131,000 pounds of thrust.

A four-nozzle vernier steering engine is also mounted on the third stage to keep the rocket pointed in the right direction.

The rocket's guidance, navigation and control system is a triple-redundant digital avionics package on the third stage.
