A secretive Russian military communications satellite arrived in geostationary orbit Sunday after a successful liftoff aboard a Proton rocket, the Russian defense ministry said.

A Russian Proton rocket rolled out to a launch pad at the Baikonur Cosmodrome on Sunday with a commercial communications satellite to broadcast high-definition television channels to millions of homes across Latin America.

Russia launched an unpiloted Progress cargo freighter Sunday from Kazakhstan, on course to deliver 2.7 tons of food, fuel, water, and supplies to the International Space Station before hauling away a no-longer-needed section of the outpost later this year to clear the way for a new laboratory module.
