Proton rocket to launch two Russian broadcasting satellites Monday

Two Russian telecommunications satellites are ready to ride a Proton rocket and Breeze M upper stage into a high-altitude orbit after launch Monday from the Baikonur Cosmodrome. The mission is set for liftoff at 7:07 a.m. EST (1207 GMT) Monday, and will last 18 hours from launch through separation of the final spacecraft, one of the longest ascents ever for a Russian rocket. Russian teams previously planned to launch the mission Sunday, but discovered a technical issue with the Breeze M upper stage after rolling the Proton rocket to the launch pad at Baikonur on Dec. 9.
