Live coverage: Cygnus supply ship captured by space station robot arm

A Northrop Grumman Antares rocket rolled out of its hangar Monday night, riding a self-propelled transporter for a mile-long trip to launch pad 0A on Wallops Island, Virginia, for a predawn liftoff Thursday with a Cygnus supply ship heading for the International Space Station.

Two veteran spacemen embarking on a marathon yearlong mission in orbit must first sprint through a busy workday Friday — suiting up for liftoff, climbing into their Soyuz spaceship, then flying to the International Space Station.

Boeing engineers have completed hotfire testing on a flight-like model of the Starliner crew capsule, clearing a major hurdle before a pad abort test and a demonstration flight to the International Space Station later this summer, Boeing announced Friday.
