Photos: Atlas 5 rolls out for Friday launch to GPS constellation

The Delta 4 rocket to launch the next Global Positioning System satellite to sustain the orbiting navigation network has been rolled out to the launch pad.

Leading all other nations, U.S. launch providers flew 44 missions in 2020 that aimed to place payloads in Earth orbit or deep space, with 40 successes. China followed with 35 successful orbital missions in 39 launch attempts.

A commercial satellite launched Sunday on a Russian Proton rocket successfully deployed in orbit thousands of miles above Earth to join Inmarsat’s new communications network providing high-speed data links between airplanes, ships and far-flung customers anywhere in the world.
