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

Russia lofted a military satellite Thursday to join a network of orbiting early warning stations detecting and tracking missile launches around the world, providing the Russian government notice of potential attack.

A refurbished SpaceX Crew Dragon spaceship linked up with the International Space Station early Saturday more than 260 miles above Earth, delivering four veteran astronauts to the orbiting research complex and temporarily raising the lab’s crew complement to 11.

An impromptu repair job Thursday appears to have stopped a leak in a Russian Soyuz spacecraft docked to the International Space Station, and the crew was back on its normal schedule Friday carrying out research and making preparations for the arrival of a Japanese cargo ship next month.
