Three Russian satellites have failed to enter orbit after they were launched
on a rocket from the Baikonur cosmodrome in Kazakhstan.
Russian aerospace experts said the satellites and the upper stage rocket
carrying them probably fell into the Pacific Ocean near Hawaii.
Officials said the satellites went off course after separating with a
booster rocket from the main launch rocket.
The satellites were to be part of a navigation system meant to rival GPS.
They were being carried on a Proton-M rocket launched earlier on Sunday.
A source in Russia's aerospace industry told Ria-Novosti news agency that
the rocket had veered off course by eight degrees after its launch.
Russia has already successfully launched a number of the Glonass satellites
this year. The navigation system is meant to be in place next year.

Regrettable! Thanks for the update, Sam.

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.

onboard computer led to the engines failing to function as normal,
giving the rocket an extra boost and taking it into the wrong orbit"
