Video: Change of command aboard International Space Station

An apparent exterior coolant leak from a Russian laboratory module at the International Space Station has been reported by the crew. It follows similar leaks that struck a Russian Soyuz crew ferry craft and a Progress cargo ship within the past year.

A Russian Soyuz spacecraft featuring a variety of avionics upgrades and other changes to improve reliability and performance docked with the International Space Station early Saturday after a two-day orbital chase, bringing three fresh crew members to the lab complex.

SpaceX rolled out a reused Falcon 9 booster for a hold-down engine firing Wednesday at pad 40 at Cape Canaveral Air Force Station, making the first use of the launch complex since a rocket exploded there in September 2016. The static fire test accomplished Wednesday was a key step in preparations for launch of a space station cargo ship Dec. 12.
