Some interesting facts from astronaut interview:
- The International Space Station travels so fast around the planet that it keeps “missing” the Earth. Gravity is pulling the station down but it never hits Earth. This is an orbit.
- “Does your heart beat faster in space?” It does the opposite because it doesn’t have to fight gravity to pump blood to each part of the body. That is why astronauts need to exercise. Without exercise their hearts will get smaller.
- Food tastes more bland in space because the ability to smell decreases. All the fluids that are normally in your legs and your feet are now in your chest and your head due to less gravity. The fluids somewhat blocks your nose. So astronauts don’t really smell their food, which is a big part of taste.
