Live coverage: Veteran three-man crew docks with space station

A Russian cosmonaut, a NASA astronaut and an Italian wrapping up her first space flight boarded a Russian Soyuz ferry craft early Thursday, undocked from the International Space Station and plunged back to Earth, landing safely on the steppe of Kazakhstan to close out an extended 200-day mission.

SpaceX fired up nine Merlin main engines at the bottom of a previously-flown Falcon 9 booster Saturday at NASA’s Kennedy Space Center, running the rocket through a practice countdown before a scheduled liftoff Jan. 18 with a Crew Dragon capsule to test the human-rated ship’s high-altitude abort capability.

Officials have accepted a Friday launch date for a commercial cargo ship to the International Space Station after Range availability scuttled notions of moving up the Atlas 5 flight by a day.
