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

This is the post-launch news briefing from NASA’s Wallops Flight Facility held after the successful return to flight by the Orbital ATK Antares rocket that delivered the Cygnus cargo ship into space.

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.

NASA and SpaceX officials are moving forward with preparations to launch the next commercial Crew Dragon mission to the International Space Station next week after a Flight Readiness Review Thursday, pending a final evaluation of a discovery by SpaceX that it has potentially been loading slightly more propellant than expected into its Falcon 9 rockets.
