Record-breaking NASA astronaut set to return home

Whitson and two others will undock their Soyuz MS-04 spacecraft from the space station and land in Kazakhstan. Whitson is completing a 288-day mission that began in November 2016, spanning 122.2 million miles and 4,623 orbits of Earth – her third longduration stay on the outpost. At the time of their landing, she will have accrued a total of 665 days in space over the course of her career, more than any American astronaut, placing her eighth on the all-time space endurance list.
