Facts about space (International Space Station)
1. Electrical instruments in space do not use fuses, because there is no gravity. Gravity helps here on Earth to pull down the strip of metal inside the fuse to cut off excessive current. But in space, things are a little bit different.
2. Astronauts use a kind of diapers when they are in EVA (Extra-vehicular Activity) missions due to the long time it takes to perform this tasks.
3. Astronauts get about 2.5 inches taller after about a week in space. Without the weight of a body compressing it, the spine’s curvature lessen and the discs between the vertebrae expand and absorb more water.
4. Astronauts coming home from a six month space station trip, come back with 15% to 20% less bone than they had when they left.
5. There are no showers in space. Astronauts wipe themselves with moistened towels and rinseless shampoo.
6. In order to be an Astronaut you need to have a big capacity to tolerate boredroom and low levels of stimulation. ( Like Chris Hadafield )
7. There is a test in JAXA (Japan Aerospace Exploration Agency), to select astronauts, and it involves doing one thousand paper cranes. Yes, origami paper cranes. And they have a deadline to make the cranes. The reason of this is that roughtly 90% of the work in space is related to assembling, repairing or maintenance of the spacecraft, and much of this work is done while using a pressuriszed suit, with a limited oxygen time (If you run out of oxygen, you are done). When the one thousand origami paper cranes are done, the time to analyze them starts. How does the firsts paper cranes compares to the lasts? If the quality is not the same, and shows deterioration of accuracy, that can imply impatience under stress.
8. Astronauts train to go to the bathroom in space.(Yeah, they have pop training. They are not that smart though.)
9. There was a flying turd incident in Apollo 10 mission.
