Live coverage: Soyuz crew lands in Kazakhstan

Engineers are troubleshooting a small air leak aboard the International Space Station that was discovered last September, NASA reported Thursday. While it poses no safety threat, the lab’s three-man crew plans to seal themselves in the Russian segment of the station this weekend to help engineers pin down the leak’s location.

A Russian Soyuz booster places the Progress 64P autonomous cargo ship into orbit for a two-day journey to deliver 5,300 pounds of fuel, water and supplies to the International Space Station.

Four astronauts strapped into their SpaceX Crew Dragon capsule, undocked from the International Space Station and plunged to a fiery pre-dawn splashdown in the Gulf of Mexico Sunday, closing out the first operational flight of SpaceX’s futuristic touch-screen ferry ship.
