The life support system installed in the space station helps astronauts live in space for extended periods of time. While in space, the life support system provides oxygen and filters out the carbon dioxide exhaled by the astronauts. In addition, astronauts go through rigorous training regimens to ensure that their bodies can handle the conditions.Know More
Since most astronauts do not spend as much time on their feet while in space as they would on Earth, their hearts have to work extra hard against gravity to move blood around their bodies. As a result, astronauts have to exercise in space each day to maintain strength in their muscles and bones. When it comes to staying clean is space, astronauts use a personal hygiene kit that contains toothbrushes, toothpaste, combs, brushes and shavers. These kits also come with specially formulated soaps and shampoos that do not require the use of water.
In order to keep the space station clean, astronauts must wipe the walls, floors, and windows using a soap that kills germs. There are four trash bins on the Space Shuttle: three for dry trash and one for wet trash. Lastly, when an astronaut goes to the toilet, the solid waste is treated to prevent any bacterial growth, and then it is dried and dumped into space.Learn more about Space Travel
Astronauts float in space because they and the spacecraft in which they are traveling are orbiting the Earth in a free-fall trajectory that matches the curvature of the planet. By free falling around the Earth, the astronauts and their spacecraft avoid burning up in the atmosphere.Full Answer >

In addition, humans require a means of transiting from Earth to space and back.Full Answer >
Astronauts have a wide variety of foods available to them, from fresh fruits and vegetables to ready-to-eat meals, such as borscht soup, Kung Pao chicken, jellied fish and shrimp cocktail. Meals are created using dehydration, vacuum sealing and irradiation to prevent spoilage.Full Answer >
Astronauts wear space suits, flight suits, maximum-absorbency garments and helmets. They typically wear blue flight suits and tennis shoes during training, and they also wear the flight suits while flying NASA T-38 jets.Full Answer >
