Night owl? Early bird? Watch a Soyuz crew plunge back to Earth Saturday morning

Tomorrow morning, Tim Kopra, Tim Peake and Yuri Malenchenko are coming home from the International Space Station. But if you live in the United States or Europe, you're going to have to get up pretty early—or stay up late—to see it happen.

The three Expedition 47 crewmembers are scheduled to undock from the station at 1:52 a.m. EDT (6:52 UTC). Their Soyuz TMA-19M spacecraft will begin its descent to Earth three-and-a-half hours later, touching down in Kazakhstan at 5:14 a.m.

Kopra, Peake and Malenchenko launched from the Baikonur Cosmodrome back in December, and will have spent 186 days in space when they depart. Earlier today, NASA astronaut Tim Kopra formally handed command of the station over to his colleague, Jeff Williams:

As the crew prepares for departure, Tim Kopra has been re-sharing some of his favorite Twitter photos from his stay aboard the station. Here are a few highlights:
