A Year in Space - Season 1 (2015)

The final hours on Earth are a series of rituals - both technological and personal - as the clock ticks down and the engines ignite.

NASA astronaut Scott Kelly boards the International Space Station and adjusts to life in space.

Danger lurks both on the ground and in orbit as the crew deals with exploding supply rockets and incoming space debris.

Fixing the space station can mean venturing outside-no easy feat 250 miles away from Earth.

So much rides on the slender thread that connects astronauts in space to family on Earth.

Packing to leave can be bittersweet after a year in space.

Returning from the ISS is a wild, scary, violent ride-but it's the only way home.

By air and land, rescue vehicles converge in the Kazakh steppe to catch three men falling from space.

After a year in space, Scott Kelly and Mikhail Kornienko reunite with their families and begin the long, painful process of readjusting to life on Earth.
