Video: Change of command aboard International Space Station

Donald Trump calls the International Space Station from the Oval Office, offering congratulations to Expedition 51 commander Peggy Whitson on breaking the U.S. astronaut endurance record.

The astronaut “is in stable condition under observation as a precautionary measure,” NASA said in a statement 10 hours after the Crew Dragon’s landing. “To protect the crew member’s medical privacy, specific details on the individual’s condition or identity will not be shared.”

NASA commentator Dan Huot has everything you need to know about Russia’s Soyuz space capsule and provides a tour inside the cramped spacecraft, which, since the end of the shuttle program, has been the only way to ferry cosmonauts and astronauts to and from the International Space Station.
