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

An unpiloted Russian Soyuz spacecraft, carrying a humanoid robot instead of cosmonauts, parachuted to a rare nighttime landing on the steppe of Kazakhstan Friday (U.S. time) to wrap up a test flight to the International Space Station that paved the way for crewed launches using upgraded Soyuz boosters next year.

Crew members on the International Space Station over the weekend continued trying to pinpoint the location of a small air leak in the research outpost’s Russian Zvezda service module, one of the oldest sections of the orbiting laboratory.

These photos show the 215-foot-tall Falcon 9 rocket and Crew Dragon spacecraft on pad 39A at the Kennedy Space Center, ready for launch on a test flight to the International Space Station with NASA astronauts Doug Hurley and Bob Behnken when weather cooperates.
