WATCH: SCOTT KELLY AND MIKHAIL KORNIENKO RETURN FROM THEIR YEAR IN SPACE

NASA astronaut Scott Kelly, left, and Russian cosmonaut Mikhail Kornienko, mark their 300th consecutive day aboard the ISS on January 21. The pair spent nearly a year at the International Space Station and are scheduled to return to Earth, landing in Kazakhstan on Wednesday morning local time (Tuesday night ET).

Scott Kelly is getting ready to head home. He handed over the reins of the International Space Station to fellow NASA astronaut Tim Kopra in a command change ceremony on Monday in preparation, and is just hours away from departure.

Kelly and his fellow “Year in Space” crew member, Russian cosmonaut Mikhail Kornienko, are scheduled to land in Kazakhstan at 10:25 on Wednesday morning local time (11:25 on Tuesday night ET). They will be joined by Russian cosmonaut Sergey Volkov for the return trip, leaving Kopra at the station with British astronaut Tim Peake and the Russian cosmonaut Yuri Malenchenko.
