One American astronaut and two Russians landed safely in Kazakhstan Wednesday after spending nearly six months on the International Space Station.
The U.S. space agency NASA announced that American astronaut Jeff Williams and Russian cosmonauts Alexy Ovchinin and Oleg Skripochka returned to Earth this week.
美国航空航天局宣布，美国宇航员杰夫·威廉斯（Jeff Williams）和俄罗斯宇航员阿列克谢·奥夫奇宁（Alexy Ovchinin）以及奥列格·斯克里波奇卡(Oleg Skripochka)本周返回了地球。
Their journey from the space station to Earth took about three and a half hours.
Astronaut Jeff Williams has now spent more time in orbit than any other American. He has spent 534 days in space during four separate missions.
It is a Russian cosmonaut who holds the world record: Gennady Padalka has spent 879 days in space.
NASA wrote about Jeff Williams’ experience at the space station. The U.S. space agency said Williams performed five space walks during his time there. During one of the space walks, Williams installed a station where commercial space flights can stop.
NASA said Williams played an important role in getting the space station ready for a private U.S. space industry – not just government-operated missions.
Williams also commented on his experience on social media. He posted a picture of Earth’s outer atmosphere and wrote, "I will certainly miss this view!"
Russian Anatoly Ivanishin took command after Williams left the station. The Russian cosmonaut remains in the space station with American Kate Rubins and Japan’s Takuya Onishi.
