Every 90 minutes the International Space Station completes an orbit of Earth. This means it sees about 16 sunrises and sunsets each day.

Pretty interesting, hey? Well, here are more things you might not have known about the International Space Station:

  1. Since the year 2000 the space station has been inhabited by over 200 people.
  2. The first module (part of the space station) was launched on 20 November 1998 and the most recent module was launched and inflated earlier this year.
  3. The space station has 915.5 cubic meters of pressurised volume and weighs more than 420 000 kilograms.
  4. The on board pressure is equal to that of a Boeing 747.
  5. The crew require almost seven tons of supplies to support a three-person crew for about six months.
  6. The International Space Station’s Water Recovery System recycles all the water used on the space station and lowers the requirement for delivered water.
  7. One working year for the crew equals 52 560 hours. That’s about 50 000 more working hours than the average South African.
  8. More than 12 kilometers of wire connects the on board electrical powers systems.
  9. To space station travels at 7 823.2 metres per second. This translates to 28 163.52 kilometers per hour.
  10. NASA has a calculator that tells you exactly when you can see the International Space Station in the sky above you. Check it out here.
  11. In 2013 the Olympic torch made its way to the International Space Station and want taken outside on a spacewalk.
  12. The space station has two bathrooms and a gym with a 360-degree view of space. The space station also has more livable space than a six-bedroom American house.
  13. Humans lose muscle and bone mass in zero gravity. Because of this astronauts must exercise for at least two hours each day.
  14. The International Space Station is four times larger that the Russian space station Mir, and five times larger than the United States’ first space station Skylab.
