ALMATY (Reuters) -U.S. astronaut Frank Rubio, who broke the record for the longest continuous space flight by an American, and two Russian cosmonauts landed in the steppe of Kazakhstan on Wednesday after more than a year on the International Space Station (ISS). Their Soyuz MS-23 capsule undocked from the ISS a minute earlier than scheduled, and took around three and a half hours to make it down to Earth, landing southeast of the city of Zhezqazghan. "It's good to be home," Rubio, 47, said with a smile after landing with Russian cosmonauts Sergey Prokopyev, 48, and Dmitry Petelin, 40.
