  • Launch Failure Delays Glonass Completion
    Posted by Robert Wall 2:59 PM on Dec 05, 2010

    Reports from Russia say the Proton-M launch on December 5 to complete the country's Glonass precision navigation and timing satellite constellation failed to complete its mission.

    The Proton was carrying three Glonass-M satellites, which would have completed the constellation of 24 operational satellites -- 26 are in orbit, but two are spares and the other four are not operational. Russia was hoping to commission the new spacecraft in about six weeks.

    Early reports are vague on what the cause of the launch failure was. The Russian space agency says the payload was placed in a "non-targeted orbit." Itar-Tass reports that the Proton-M was providing too much thrust and that stage separation occurred at the wrong altitude. RIA Novosti suggests the rocket had veered off course after launch.

    Roscosmos says a board has been established the investigate the cause of the mishap.
