Moscow: Three Russian navigation satellites crashed into the Pacific off the US state of Hawaii Sunday after the rocket carrying them failed to reach orbit, officials from the Russian space agency said.
The capsule carrying the three Glonass satellites plummeted into the sea 1,500 kilometres (900 miles) off Honolulu, one official told Russia`s RIA-Novosty news agency, adding that there were no casualties or damage.
The failure is a setback for Russia`s attempt to put a satellite navigation system in place to rival the United States`s GPS (Global Positioning System) and steal a march on Europe`s fledgling Galileo system.
Prime Minister Vladimir Putin has underscored the strategic significance of developing the Glonass system to ensure Russia`s technological independence.
"Following a failure of the Proton rocket and the rocket booster, three Glonass-M satellites crashed into an area of the Pacific Ocean well off sea lanes about 1,500 kilometers northwest of Honolulu," Interfax quoted a Russian space agency official as saying.
The rocket carrying Russia`s answer to GPS had blasted off as planned from the Baikonur cosmodrome in Kazakhstan at 1:25 pm (1025 GMT).
Once separated from the Proton rocket, a second-stage booster rocket with the three satellites aboard should have put them in orbit about 20 kilometres (12 miles) above the earth.
"The ballistics experts have checked everything: the upper-stage rocket with the satellites is not on the main, intermediate nor emergency orbit," a source told RIA Novosti.
The three Glonass-M satellites, weighing 1.4 tonnes, were supposed to complete a constellation of satellites already put in place by Moscow.;
Putin said in April that Russia planned to equip all new cars sold in Russia in 2012 with the new navigation system, developed by the Russian military in the 1980s.
The Russian prime minister said Moscow planned to launch a total of seven new Glonass satellites which would ensure coverage of the entire planet, bringing to 27 or 28 the number of operational satellites.
Russia would spend 1.7 billion rubles (40 million dollars in 2011, after two billion rubles spent in 2010), Putin said.
Rokosmos, the Russian space agency, said in 2008 that Venezuela and Cuba were interested in adopting the new system.
Russia`s defence ministry confirmed the loss, but insisted Sunday`s embarrassing accident would not affect the roll-out of the new positioning system.
"There are currently 26 satellites in the Glonass constellation, including two emergency satellites. This allows complete coverage of Russian Federation territory," the ministry said in a statement.
"The Russian space industry`s capacity enables us to react rapidly to what`s happened," it said, adding that the system would be fully in place next year in any case.
