Donald Trump makes space call to US astronaut
US astronaut Peggy Whitson has broken the record for the most time spent in space by an American.
The International Space Station commander has surpassed the previous record of 534 days, two hours and 48 minutes, set last year by Jeffrey Williams.
Ms Whitson is already the world's most experienced spacewoman and female spacewalker and, at 57, is the oldest woman to have gone into space. By the time she returns to Earth in September, she will have logged 666 days in orbit over three flights.
As part of the celebration, Ms Whitson received a special phone call from President Donald Trump, who spoke to her from the Oval Office, along with his daughter Ivanka and Nasa astronaut Kate Rubins. The world record - 879 days - is held by Russian astronaut Gennady Padalka.
