15 Out-of-This-World Facts About the International Space Station

9. The ISS is probably one of the only places you can actually smell space. A former ISS astronaut has described how a “metallic-ionization-type smell” occurs in the area where the pressure between the station and other docking crafts is equalized.

10. Currently, the ISS is the third brightest object in the night sky after the moon and Venus. Eagle-eyed stargazers can even spot it if they look closely enough—it looks like a fast-moving airplane. If you can’t find it, NASA has a service called Spot the Station that texts you when and where it will pass over your location. If you want the opposite view (though we’re pretty sure you won’t be able to spot yourself), there is a live video feed pointing towards Earth that runs when the crew is off-duty.

11. Though the plan is to de-orbit the ISS in 2024, the oldest module of the station—the Russian-built and American-financed component called “Zarya,” first launched in 1998—can function until 2028 (as will The Unity, the first entirely American ISS component, which was also launched that year). Once the ISS kicks the bucket, the Russians plan to add their leftover modules to their new station, OPSEK (or Orbital Piloted Assembly and Experiment Complex).

12. Because the human body tends to lose muscle and bone mass in zero gravity environments, all astronauts aboard the ISS must work out at least two hours a day to maintain normal Earth-based bodily health.  

13. The electrical systems on the ISS include 8 miles of wire. That’s longer than the entire perimeter of New York City’s Central Park.

14. Astronauts eat three square meals a day on the ISS, but when they sit down for a meal, they don’t sit down at all. There are no chairs around the main eating area. Instead, the astronauts simply stabilize themselves and float. Diners have to be very slow and careful when bringing food to their mouths so it doesn’t accidentally float across the station. Also, they can’t just stroll over to the refrigerator and grab a snack—all the food is canned, dehydrated, or packaged so it doesn’t require refrigeration.  

15.  Oxygen in the ISS comes from a process called “electrolysis,” which involves using an electrical current generated from the station’s solar panels to split water molecules into hydrogen and oxygen gas.
