21 Fun Facts about the International Space Station

Floating 240 miles above Earth, the International Space Station is a technological marvel – the greatest undertaking in human history – a project that only succeeded because of the cooperative efforts of over a dozen nations. Here are 21 fun facts about the International Space Station:

1. The ISS launched in the late 90s.

The International Space Station started in 1998. The first modules of the station were launched by the Russians and the Americans. The Russians first went with ‘Zarya’. NASA followed two weeks later with ‘Unity’.

2. It was a labor between many nations.

Sixteen countries participated in the construction of the station, not just the USA and Russia but also Canada, France, Spain, the UK, and Belgium, to mention but a few.

3. It wasn’t a one-flight job!

It took 136 space flights to complete the International Space Station. NASA and its partners used seven different types of vehicles to get the relevant components to space.

4. The ISS is a beacon in the night.

The ISS is the third brightest object in the sky (the brightest are the Moon and Venus). You can sign up for a service that allows NASA to send you a text whenever the station is flying over your location.  It’s called Spot the Station. Depending on the time of day or night, you can see it with the naked eye.

5. The ISS is extremely fast.

The International Space Station is moving at a speed of 5 miles per second. It circles Earth every 90 minutes. At that speed, it would make a round trip to the Moon in a day.

6. The ISS is a space record-breaker.

With a length of 109 meters and a pressured volume of 32,300 cubic feet, the ISS is the largest manned object mankind kind has ever put into space.

7. In fact, it’s a record-breaker on Earth!

At 460 tons, it is the biggest and heaviest object ever made.

8. It was also very expensive.

Somewhat larger than a 6-bedroom house in terms of livable space, the ISS is also the most expensive object mankind has ever made, costing more than $120 billion.

9. What does The ISS do?

It was designed to conduct space-related research. Besides exploring the possibility of future space travel, scientists from a wide range of fields also study the effect of microgravity on the human body, not to mention dark matter and other important matters.

10. There’s all mod cons up in Space.

Even though they live an isolated life, the astronauts on the ISS enjoy a number of modern amenities, including a gymnasium and two bathrooms.

11. We’re not taking the…

The rumours you have heard are true. The ISS takes urine from the crew and lab animals and funnels it back into the water supply. Of course, the urine is filtered and treated appropriately to make it safe for human consumption.

12. Space… Smells?

According to some astronauts, space has a smell. If you are standing in the right place when the pressure between the station and a docking craft is equalised, you will catch a ‘metallic-ionised’ odour in the air.

13. Exercise is essential up here.

The crew of the International Space Station spends two hours a day working out. This is the only way to prevent the loss of muscle and bone mass.

14. It’s not all business!

There are 52 computers on the station. The crew members have internet access which they use for entertainment and communication purposes.

15. How do you eat in The ISS?

The people living in the station eat three meals a day. Rather than sitting, they just float. Their meals constitute canned and dehydrated food items. Meals are very slow because food can’t be allowed to escape from its tray.

16. The floating barbershop!

Haircuts are equally difficult on the ISS. Astronauts use special clippers which are attached to a vacuum that collects all the hair. Stray hairs could clog the air filters.

17. Earth From above!

If you want to know what it is like to look at Earth from the ISS, there is a live video feed from the station that can show you that perspective.

18. Powdering your nose is an adventure…

The International Space Station toilets are rather special. You have to strap yourself in to use them. Otherwise, you could float off at the most inopportune moment.

19. There’s US-Russian division on H2O!

American and Russian crew members use separate water supplies. This is because they use different substances to control bacteria: silver for the Russians and iodine for the Americans. The substances cannot be allowed to mix.

20. Quicker than a 30 degree cycle!

Astronauts don’t necessarily do laundry. Old clothes are burnt. New clothes are shipped to the station in an unmanned craft.

21. How do astronauts breathe on The ISS?

To make breathable cabin air, water is split by electrolysis into oxygen and hydrogen  The oxygen is circulated onboard and the hydrogen is exhausted into space.
