Live coverage: 400th Proton rocket takes off with Russian satellite

Armed with capital and an anchor customer for a trailblazing satellite life extension service, Orbital ATK has signed a contract to loft its first robotic servicing tug aboard a Russian Proton rocket in 2018 on a shared launch with a Eutelsat communications satellite.

Russian ground controllers decided Tuesday to delay the docking of a Progress supply freighter to the International Space Station until Thursday after telemetry signals indicated two radar navigation antennas may not have deployed following the ship’s launch from Kazakhstan.

Russia’s Progress MS-23 cargo freighter launched Wednesday from Kazakhstan on a mission hauling more than 2.7 tons of fuel, food, experiments, and supplies to the International Space Station.
