Space diapers - During space walks, astronauts must wear special space diapers called MAGs (Maximum Absorbency Garment). These items can hold up to two liters of liquid.

No getting your breath back - If an astronaut is exposed to the vacuum of space without a suit, they can't breathe. The rapid decompression would explode their lungs.

Space illnesses - Around 80% of astronauts become ill while in space. Vomiting, dizziness and nausea are some of the symptoms that generally last two to three days.

Seasoning food in space - To avoid seasoning flying all over the place, astronauts use special liquid salt and pepper on their food.

Ventilation - It's crucial for astronauts to have good ventilation during sleep. This is because warm air isn't abundant in space, and bubbles of carbon dioxide can deprive astronauts of oxygen.

Heart rate - The heart rate drops in space, which can be very dangerous. So astronauts do hours of physical exercise to keep the heart in good shape.

Haircuts in space? - Astronauts spend months in space, so they need to cut their hair. How, you ask? They need a machine with a tube and a vacuum so that hairs don't escape and float around the ship.

Resting feet - Because they're in a low gravity environment, astronauts don't need to walk, so the skin on their feet starts to soften and peel. When taking socks off, they have to be careful that their dead skin doesn't get spread around the cabin.

Snoring - A 2001 study showed that astronauts who normally snore on Earth manage to sleep in space without making any noise.

Preparation - Before a space walk, astronauts wear their suits for hours. It's so they can adapt to the pure oxygen and get ready for the task ahead.

Sunrise all day - The sun rises every 90 minutes for everybody on the International Space Station. It orbits the earth at a distance of 27,500 km, so astronauts see the sun rise 16 times every day!

Scissors - Scissors are one of the most important items in space, because sealed food is so hard to open.

Refreshments - Drinking soft drinks in space is dangerous because carbon dioxide works differently in space than on Earth, and can have an adverse affect.

Music - Mission Control Centers - which manage the activities of missions and aerospace vehicles leaving Earth - play music according to each astronaut's taste to wake them up.

Tears - Tears don't run down your face like on Earth. In space they form a ball of water on your eye.

Water doesn't run - Squeezing water from a cloth is almost impossible. The liquid stays on the surface of the cloth due to the lack of gravity.

Landing on earth - Astronauts have told of having problems moving their arms and legs after returning to Earth. This phenomenon is known as 'Second Birth.'

Tortillas - To avoid having crumbs floating around in space, astronauts use tortillas instead of bread.

Seeing the Earth - Human impacts on Earth such as pollution, city lights and explosions from natural gas extraction can be seen from space.

Bathroom - As there is not enough gravity to flush liquids, astronauts need hours of training to use a toilet properly in space. They get strapped down to the toilet and need a lot of experience to avoid disasters.

Brushing teeth - Astronauts have to swallow their toothpaste to get rid of it.

Cutting nails - Cutting one's nails in space is dangerous. A tiny piece could float around and get someone in the eye, so nails have to be cut near to an air vent.

Leisure - There are days off in space too. Astronauts use free time to read, relax and take space photographs.

Washing clothes - Washing clothes in space would use too much water. Astronauts try to use the same clothes for as long as possible. After using them they send them out with the rest of the trash that will burn in the atmosphere before returning to Earth.

Sleeping bags - They can't use normal beds, so astronauts sleep in sleeping bags stuck to the wall.

Growing in space - Being in space will make your spine longer and straighter because there is no gravity pressure. Some astronauts come back to Earth up to 7cm taller.

Dropping things - Astronauts have admitted that they drop things a lot when they come back to Earth because they have to get used to gravity again.

Awesome photographs - A big hobby for a lot of astronauts is taking awesome photos of space and the Earth. They use huge telephoto lenses to get every bit of detail of the stars and the Earth.
