Photos & Video: Proton-M Rolls Out After Year-Long Grounding

A Russian Proton rocket is moved to the launch pad at Site 81/24 on June 5, 2017 in preparation for the launch of EchoStar-21 – marking Proton’s comeback mission after staying on the ground for almost a full year due to problems related to the engines powering the vehicle’s second and third stage. Proton’s mission will last for ten minutes before the Briz-M upper stage takes over for a five-burn, nine-hour mission to lift the 6,871-Kilogram mobile communications satellite into a Geostationary Transfer Orbit.
