The main cause of the loss of Russia's three Glonass-M satellites was due to human error from fueling the booster rocket with an excess of 1.5-2 tons of fuel, the head of the Russian state commission probing the incident said on Friday.

The main cause of the loss of Russia's three Glonass-M satellites was due to human error from fueling the booster rocket with an excess of 1.5-2 tons of fuel, the head of the Russian state commission probing the incident said on Friday.

The excessive fuel caused the DM-3 booster rocket to deviate from its course, leading to the subsequent loss of the satellites in the Pacific Ocean earlier in the week.

"According to preliminary information, the problem was not with the fuel service unit at the launching site, but with one of the sensors showing the fuel level," Gennady Raikunov, the head of the Central Scientific Research Institute of Machine Building, who also heads the investigation commission, said.

"We do not rule out the factor of human error," he said adding that the Russian rocket space corporation Energia may be linked to the incident.

The December 5 launch of the Proton-M carrier rocket was supposed to conclude the forming of Russia's navigation system Glonass, similar to the U.S. GPS. However, the rocket, which blasted off from the Baikonur Space Center in Kazakhstan, deviated from its course by 8 degrees, resulting in the loss of the DM-3 booster with the satellites. According to reports, the spacecraft fell into the Pacific Ocean to the northwest of Hawaii.
