Three astronauts will be returning to Earth in the wee hours of Monday morning from the International Space Station, and you’ll be able to watch them live, although you’ll have to get up early. NASA astronauts Shane Kimbrough and Russian cosmonauts Sergey Ryzhikov and Andrey Borisenko will be departing the ISS in a Soyuz capsule just before 4 a.m.

It will be the end of a 173-day mission on the ISS for the three astronauts, who arrived at the station last October. They will enter the Soyuz capsule at 12:40 p.m. eastern time and undock at 3:57 a.m. It will take them three and a half hours to reach the Earth’s surface.

The departur emeans that NASA astronaut Peggy Whitson is the new commander of the ISS. She’s been there since November, and actually held the positoin before in 2008 when she became ISS’s first commander.

“Three crew members aboard the International Space Station are scheduled to depart the orbiting outpost Monday, April 10,” the NASA statement reads. “Coverage of their departure and return to Earth will air on NASA Television and the agency’s website. Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineers Sergey Ryzhikov and Andrey Borisenko of Roscosmos will undock their Soyuz MS-02 spacecraft from the space station at 4 a.m. EDT and land in Kazakhstan at 7:20 a.m. (5:20 p.m. Kazakhstan time). Their return will wrap up 173 days in space for the crew members since their launch last October.”
