Watch as Progress docks with Space Station bringing a holiday delivery

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.

Mission control halted the expansion of Bigelow Aerospace’s experimental space station module Thursday after the structure did not grow as predicted when air began flowing into it.
