42Fun Facts
Here are some more things about our International Space Station
you might not have known… tell your friends! Amaze your family!
Did you know…
• Space Station’s living space is about the size of
a 6-bedroom house
• Weightless Station astronauts sleep in any direction
with no bed, just a sleeping bag strapped to a wall
so they don’t float around
• The Station’s weightless environment means toilets
have to be specially designed to work like vacuum
cleaners and suck wastes in, recycle most of the
water, and seal the rest in plastic bags
• Weightlessness also makes showering a challenge –
water droplets can float anywhere and really damage
computers, machines, and so on – so astronauts rub
water and soap on and sponge it off again
• There are about 8 miles of wiring in the Station’s
electrical system
• Over 100,000 people around the world worked
together to make the Space Station possible
• Astronauts have to exercise hard for at least 2 hours
every day to keep their muscles and bones from
getting too soft, which is what they would otherwise
do without having gravity to work against
• Over 50 computers keep the Station’s systems working
• Astronauts, when they’re enjoying what little free time
they get, often spend it reading, listening to music,
emailing or otherwise keeping in touch with their
families and friends on Earth, or taking pictures
of Earth and space out the windows
• Research on Station continues to make discoveries
