This week, two Russian and one American astronauts left the ISS and landed in Kazakhstan. This is how we go from space to the surface of our planet.

They were looking forward to getting out of there, but that doesn’t make the return trip any more comfortable.

This week, Shane Kimbrough, an American astronaut and two Russian cosmonauts named Sergey Ryzhikov and Andrey Borisenko have landed in Zhezkazgan, a remote region of Kazakhstan, after almost six months aboard the International Space Station (ISS).

They were traveling aboard a Russian Soyuz MS-02 capsule that left the ISS on the 10th at 9 a.m. Spanish time and landed in southeastern Kazakhstan at 12:20 noon. Total, just over three hours to travel the 400 kilometers that separate the station from the earth’s surface.

“It is really good to be part of something so big, bigger than ourselves and even bigger than a nation,” Kimbrough said during a ceremony last Sunday when he handed over command of the ISS to the astronaut. Peggy Whitson, the first woman to hold this position for the second time.
