An International Launch Services Proton rocket launched at 7:16 p.m. EST Sunday (0016 GMT Monday) with the Yamal 401 communications satellite for Gazprom Space Systems. The rocket’s Breeze M upper stage will deploy the spacecraft into geostationary orbit about nine hours after liftoff.

Engineers from Boeing and a team of subcontractors have finished building the first pair of six new solar arrays to bolster the International Space Station’s aging electrical system ahead of their launch to the orbiting outpost as soon as May aboard SpaceX’s next Cargo Dragon mission.

Packed with food, hardware and experiments in biology, Earth science and space technology, a Falcon 9 rocket and Dragon supply ship lifted off Monday from Cape Canaveral destined for the International Space Station.
