Russian launch fails; $200m satellites lost

Rocket that crashed in Kazakhstan facility was carrying 172 tons of toxic propellant

A Russian rocket carrying three navigation satellites worth around $200 million crashed shortly after lift-off from the Russian-leased Baikonur launch facility in Kazakhstan on Tuesday after its engines suddenly failed.

The accident led to a large spill of heptyl, a highly toxic rocket propellant, but there were no reports of casualties or of any immediate threat to nearby settlements.

State-run Rossiya-24 television showed footage of the Proton-M booster rocket veering off course seconds after lift-off. It fell apart in flames in the air and crashed in a ball of fire near the launch pad.

Interfax news agency quoted an unnamed source as saying launch-pad personnel were in bunkers when the rocket lifted off.

Russia's space agency Roscosmos said the accident had been caused by the emergency switch-off of the rocket's engines 17 seconds into the flight.

"There was an accident during the Proton-M launch. The rocket fell and exploded on the territory of the launch site," a Roscosmos spokesman said, adding an investigation commission has been set up.

Russia's state-run RIA news agency said the switch-off could have been caused by a problem with the engine or the guidance system.

The rocket contained 172 tons of highly toxic heptyl propellant, Kazakh Emergencies Minister Vladimir Bozhko told an emergency government meeting.

Talgat Musabayev, head of Kazakhstan's space agency Kazcosmos, said nitric oxide - a product of burning heptyl - was much less toxic for humans. He said it was raining in the area, so toxic clouds would probably not reach the town of Baikonur some 60 km away.

However, the authorities instructed locals to stay at home and not to open windows, and ordered shops and public catering to close, said Kazakh Interior Minister Kalmukhambet Kasymov.

The estimated loss from the three satellites, meant for Russia's troubled Glonass satellite navigation system, was about $200 million, Rossiya-24 reported. Russia plans to spend more than 300 billion roubles ($9.1 billion) by 2020 on Glonass, its answer to the US GPS system.

The system, first conceived by the Soviet Union more than 40 years ago, has been plagued by failed launches, including one in 2010 in which three satellites were also lost, and by suspicions of corruption and embezzlement. Its chief designer was dismissed last year during a fraud investigation.

The Proton rocket, known at the time under its UR-500 code, made its first test flights in the mid-1960s.

It was originally designed as an intercontinental ballistic missile to carry a nuclear warhead targeting the Soviet Union's Cold War foe the United States, but it was never deployed as such.

Several crashes of Proton rockets accompanied by heptyl spills have led to temporary strains in relations between Russia and Kazakhstan.

Russia is increasing spending on space and plans to send a probe to the moon in 2015, but the pioneer program that put the first man in space in 1961 has been plagued in recent years by setbacks, including botched satellite launches and a failed attempt to send a probe to a moon of Mars.
