美俄宇航員在國際空間站停留一年後返回地球大綱
After 340 days in orbit, American astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko have returned safely to Earth.
在太空軌道上停留340天后，美國宇航員凱利和俄羅斯宇航員科爾尼延科安全返回地球。
A Russian Soyuz spacecraft carrying Kelly and Kornienko and a second Russian cosmonaut, Sergey Volkov, made a soft landing on the frozen steppes of Kazakhstan early Wednesday morning, three hours after separating from the International Space Station. Volkov is back after spending the last six months aboard the ISS, the typical mission length for space station crews.
星期三清晨，運載凱利、科爾尼延科和另一名俄羅斯宇航員沃爾科夫的俄羅斯聯盟號飛船在天寒地凍的哈薩克斯坦平原地帶安全着陸。在此3小時前，聯盟號飛船從國際空間站起航。沃爾科夫在國際空間站停留了6個月，宇航員在國際空間站執行任務通常都是半年時間。
Kelly now holds the American record for the longest continuous time in space, as he and Kornienko circled the world 5,440 times aboard the ISS, covering 144 million miles and witnessing 10,880 orbital sunrises and sunsets.
凱利目前是在太空停留時間最長的美國宇航員，他和科爾尼延科在國際空間站上環繞地球飛行了5440圈，飛行總長1億4千4百萬英里，看到了1萬零880次日出日落。
The duo's mission was designed to measure how a long-term stay in a microgravity environment impacts the human body and mind, with an eye toward planning for future multi-year missions that will be necessary to take crews to Mars or other places in the solar system.
這兩名宇航員的使命是測試長期處於微重力環境對人類身體和心智的影響，以便爲將來飛往火星或太陽系其它地方需要持續數年的宇航使命制定計劃。
