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

Running two days later after a last-minute abort Sunday, a Russian Progress resupply and refueling freighter lifted off in a blanket of fog Tuesday from the Baikonur Cosmodrome to deliver three tons of cargo, propellant and water to the International Space Station.

An unpiloted test flight of Boeing’s Starliner crew capsule to the International Space Station will be delayed from its previous target launch date of April 2 until at least May, after the arrivals of Russian Soyuz and SpaceX Crew Dragon ships bringing fresh crew members to the orbiting complex, NASA officials said Monday.

NASA is working with the Russian space agency to potentially extend crew stays on the International Space Station, the agency’s acting administrator said last week, as a cushion against expected delays in the development of commercial crew capsules by Boeing and SpaceX.
