A capsule carrying a crew of three from the International Space Station, including record-setting United States astronaut Christina Koch, landed in Kazakhstan on Thursday, a live feed by Russian space agency Roscosmos showed.

The touchdown on a snow-covered steppe also marked the return to earth of Italian astronaut Luca Parmitano and Russia’s Alexander Skvortsov.

Koch’s 328-day space mission broke the record for the longest continuous stay in space by a woman, previously held by NASA’s Peggy Whitson.

Launched into orbit last March, Koch’s mission was extended in April from its original span of six months to nearly a year after she was already aboard the station.

NASA said Koch’s lengthy mission will provide researchers with much-needed data on how the weightlessness of gravity and space radiation affects the female body on long-duration spaceflights.

That science, to be studied in the coming months, could prove useful for the U.S. space agency’s aim of building a permanent space station on the moon’s surface within the next decade.

US astronaut Scott Kelly’s 340 days in orbit starting in 2015 demonstrated that long-term spaceflight causes human health effects such as thickening of the carotid artery and retina, changes in gene expression and slight cognitive impairment for men.
