Two Russian cosmonauts have returned to Earth after a record-long stay aboard the International Space Station (ISS), but for one of them, the past 374 days has amounted to barely a third of his total time spent in space.
Oleg Kononenko and Nikolai Chub, along with NASA astronaut Tracy Caldwell Dyson, landed on Russia's Soyuz MS-25 spacecraft on Monday (Sept. 23). The 7:59 a.m. EDT (1159 GMT or 4:59 p.m. local time) touchdown on the steppe of Kazakhstan concluded Kononenko and Chub's more than yearlong mission and a 184-day stay on the ISS for Dyson.
Together with the time she logged on two previous spaceflights, Dyson is now just one day short of tying Chub's single mission tally of 374 days (373 days, 20 hours and 13 minutes) in Earth orbit.
