在轨 237 天后，宇航员返回地球
Four astronauts have splashed down safely in the Pacific Ocean off the coast of Los Angeles, bringing an eight-month mission to a close.
The Crew-12 team – NASA astronauts Jessica Meir and Jack Hathaway, European astronaut Sophie Adenot and Russian cosmonaut Andrey Fedyaev – spent 237 days in space. During that time, they circled the Earth more than 3,700 times and travelled over 100 million miles. Recovery teams reached their capsule shortly after it landed in the water.
While on board the International Space Station, the crew carried out hundreds of hours of scientific research. Their experiments included growing stem cells in space, producing medical fluids on demand and studying how certain bacteria might damage the heart.
The mission also included several spacewalks. Jessica Meir stepped outside the station four times, bringing her career total to seven. That puts her third among NASA's women for the number of spacewalks. Sophie Adenot completed three spacewalks and became the first French woman ever to work outside the station.
For Hathaway and Adenot, it was their first trip into space, while Meir and Fedyaev were making their second. After a period of medical checks, the astronauts will slowly readjust to life under Earth's gravity.
四名宇航员乘坐的飞船在洛杉矶外海的太平洋上安全溅落，为一次长达八个月的任务画上了句号。
“乘员-12”的成员包括 NASA 宇航员杰西卡·梅尔和杰克·哈撒韦、欧洲宇航员索菲·阿德诺，以及俄罗斯宇航员安德烈·费佳耶夫。他们在太空中度过了 237 天，绕地球飞行了 3700 多圈，总航程超过 1 亿英里。飞船落水后不久，回收人员就赶到了现场。
在国际空间站期间，他们完成了数百小时的科学实验，包括在太空中培养干细胞、随时按需制备医用液体，以及研究某些细菌会如何损伤心脏。
任务期间还安排了几次太空行走。杰西卡·梅尔出舱四次，个人累计达到七次，在 NASA 女宇航员中排第三。索菲·阿德诺完成了三次太空行走，成为第一位在空间站外工作的法国女性。
对哈撒韦和阿德诺来说，这是他们第一次进入太空；梅尔和费佳耶夫则是第二次。接受一段时间的医学检查后，几位宇航员将慢慢重新适应地球的重力。
