Every 90 minutes, the International Space Station, flying at 17,500 miles per hour, completes one loop around the earth. That fact is mind-blowing enough, but the action on board the ISS can be even more fascinating. And now National Geographic Channel is giving us a chance to experience it with this Friday’s special, Live From Space.

The two-hour program takes us into orbit with astronauts Rick Mastracchio and Koichi Wakata, while astronaut Mike Massimino hangs with host Soledad O’Brien at Mission Control in Houston. We’ll get a guided tour of the ISS and see how our greatest explorers live for months in microgravity. We’ll learn how they sleep upside down, stay fit, maintain personal hygiene and, of course, use the toilet.

We’ll witness fantastic experiments, plus incredible shots of the planet, from sunset and sunrise, to city lights and green aurora, to lightning storms and shooting stars. And we’ll even participate, as viewers will be able to chat via video with the astronauts and have their faces beamed into space. A first-of-its-kind second-screen experience will also allow viewers to track the space station while exploring the interests of people under its path.

As you might guess, it’s a pretty ambitious undertaking. Get a taste of the action (no pun intended) in the clip below, then check out the show this Friday at 8 p.m. Eastern/5 p.m. Pacific. You’re not gonna wanna DVR this baby. After all, it’s live.
