Video: Soyuz MS-01 leaves the space station for landing

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.

A veteran Russian cosmonaut and two spaceflight rookies rocketed into orbit from a Kazakh launch base Wednesday on the first flight of a new-generation Soyuz capsule, kicking off a two-day pursuit of the International Space Station.

The media briefing came after the agency formally pushed back the launch of the SpaceX Crew-9 mission to the International Space Station from mid-August to late-September.
