Live coverage: Veteran three-man crew docks with space station

Wrapping up a two-day chase since launching from Virginia’s Eastern Shore, a commercial Cygnus cargo craft arrived at the International Space Station Monday with more than 7,200 pounds of supplies and experiments, the second freighter to reach the orbiting complex in 15 hours.

Orbital ATK transferred an Antares rocket and Cygnus supply ship to their launch pad on Virginia’s Eastern Shore late Thursday for a liftoff now targeted for Monday with nearly 7,400 pounds of cargo heading for the International Space Station.

Construction crews at NASA’s Kennedy Space Center are making steady progress outfitting the Space Launch System’s mobile platform with umbilical connections and access arms, and the walkway for astronauts to board the rocket is the most recent arrival at the Florida spaceport.
