WATCH: President Trump, Ivanka call NASA astronauts in space

This event has ended.

President Donald Trump will be joined by first daughter Ivanka Trump in the Oval Office on Monday to call NASA astronaut Peggy Whitson live on board the International Space Station.

The call, which NASA astronaut Kate Rubins is scheduled to join as well, will be to congratulate Whitson on her record-breaking stay aboard the International Space Station.

Whitson, commander of the station's Expedition 51 crew, officially broke the American record for most cumulative days in space on Monday, surpassing NASA astronaut Jeff Williams' prior record of 534 days. Russian cosmonaut Gennady Padalka holds the world (or out-of-this-world) record, having spent 879 total days in space.

She is the first woman of any nationality to command the space station twice. She also holds the record for most spacewalks conducted by a female astronaut.

The call is scheduled to start at 10 a.m. EDT and last for 20 minutes.
