Float Through The International Space Station In Ultra-HD

Excited for the August 21 eclipse? Visit our Eclipse 2017 page to explore the science, history, and myths of the event. The Curiosity team will be viewing the eclipse alongside NASA in Carbondale, Illinois. Follow us on Facebook for live videos, trivia, and interviews on the big day.

It's fun to talk about what life is like for astronauts—What do they eat? How do they sleep? What's it like to brush your teeth in space?—but knowing what the experience is really like is something completely different. To give people a first-person view of our planet's space station, NASA released this stunning, 4K quality footage. Sit back and take a floating tour of the place our astronauts call home.

  1. The first space flights were so short that there was no need to give astronauts a way to use the bathroom. This required one astronaut to pee in his own suit during a delayed takeoff. 00:26

  2. By Apollo 11, NASA had developed a containment system that astronauts wore under their suits. For space shuttles, they developed high-tech diapers that are still worn today. 01:48

  3. Today, astronauts use space toilets that require them to pee into a tube that vents urine into space, where it turns into gas. Solid waste is also sucked away, but stored until the return to earth. 02:19
