Video: Progress launches and docks

A Chinese Kuaizhou 1A rocket launched Saturday under the auspices of the commercial launch provider Exspace and successfully deployed a tech demo satellite into orbit, state media reported.

A Long March 6 booster took off Tuesday from China with three commercial Earth observation satellites designed to record high-definition video and color imagery from a perch more than 300 miles above the planet.

Astronauts Terry Virts and space station commander Barry “Butch” Wilmore ventured back outside Sunday for their third spacewalk in eight days to complete initial preparations for upcoming dockings by commercially developed Boeing and SpaceX crew ferry ships.
