Live coverage: Three-man crew docks with space station

The United Launch Alliance Atlas 5 rocket, standing 194 feet tall and and weighing 720,000 pounds, generates 860,000 pounds of thrust from its main engine to launch the Orbital ATK Cygnus cargo ship on the OA-7 mission to the International Space Station.

The first Soyuz rocket to launch from a new cosmodrome in Russia’s Far East is being assembled for liftoff in April with a package of small research satellites.

A European environmental satellite launched Tuesday from Russia’s Plesetsk Cosmodrome to begin a mission of at least seven years measuring the height, color and temperature of the world’s oceans. The Sentinel 3A spacecraft lifted off aboard a Rockot booster at 1757 GMT (12:57 p.m. EST).
