Video: Change of command aboard International Space Station

In a rapid-fire crew rotation, a NASA astronaut and two Russian cosmonauts are packing up for the trip back to Earth Saturday, leaving the International Space Station just eight days after the arrival of another three-person crew and three weeks before their own replacements arrive to boost the lab’s crew back to six.

A Russian Soyuz spacecraft carrying three space station crew members hurtled back to Earth Thursday, completing a fiery plunge back through the atmosphere before settling to a frigid touchdown on the snowy steppe of Kazakhstan to close out a 139-day mission.

Bad weather offshore has forced SpaceX and NASA to delay Thursday’s planned launch of the Crew Dragon by a day. Better conditions are expected on Friday for a 5:49 a.m. EDT (0949 GMT) liftoff from the Kennedy Space Center.
