The astronaut’s body and the space shuttle experience a large amount of stress through turbulence as they pass through the Earth’s atmosphere

The strangest condition in space is the lack of gravity. Gravity is a force that makes objects move toward each other. The Earth’s gravity keeps your feet on the ground and makes objects fall down by pulling them toward Earth. On a spaceship, there is no gravity and everything floats in the air. Velcro is used to anchor objects and prevent them from floating around. It takes time for an astronaut’s body to adjust to living in space and many astronauts suffer from space sickness for the first few days or weeks of a mission.

Astronaut apparel has evolved over the decades from Mercury’s aluminium foil-looking outfits to the bulky, 275- pound whites now used on space walks outside the space station. The U.S. suits are easier to work in for long periods of time but their complexity causes more maintenance. The one-size-fits-all Russian suits are used a few times and thrown away, but they are also not easy to work in. NASA is hoping to make new suits that are both high-tech and low-maintenance.
