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

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 booster arrived at its launch pad on the Kazakh steppe Sunday, the last stop before liftoff Wednesday with a three-person crew bound for the International Space Station.

A Russian Soyuz booster lifted off Friday from Kazakhstan on a complex mission to deploy 73 satellites into three different orbits, including a Russian spacecraft to locate forest fires, 48 CubeSats for Planet’s global Earth observation fleet, and eight nanosatellites for Spire Global’s commercial weather network.
