​ ​ = = ​​ LIFE IN SPACE By: Elaina & Bri(:

Astronuats have a very challanging life living in space. For this wikispace, how astronauts live there life in space.   Usally the way astronauts sleep is "free floating" which is basically where they just float around and sleep anywhere. Or in some places they have sleeping bags that are strapped onto a pole or onto the ground and they just fasten themself's in. Just like in this picture.. *EATING Eating in space is pretty much the same as eating on earth, expect there foods are packaged and specially treated to preserve them and prevent bacteria from growing on it. Either know there packaged and stuff, they still eat the same foods as us. Such as steak, fruits,etc. Before they came up with the packageing method they used to eat out of tubes that have processed foods in them. For example: Look at the picture below.
 * Sleeping



*EXCERSING On Earth people are always moving against the force of gravity, with their muscles and bones supporting their body. In space the body does not need to do this supporting work, since there is no force of gravity. This makes the bodies bones and muscles become weaker. To keep this from happening the astronauts have to exercise about two hours every day using exercise machines, such as treadmills and ergometers, which they have to be strapped to.

*BREATHING
While they are living in there pace shuttle, they breathe artificial "air" that is almost the same as the air on Earth. It is made up of 20% oxygen and 80% nitrogen similar to the air we breathe and it is at a pressure of 14.7psi which is the same as the atmospheric pressure on earth.  *CLOTHING **J-Wear** is the line of clothing that most astronauts wear, designed just for use by astronauts during space missions. It includes underwear, shirts, pants and socks. The clothing is anti-bacterial, water-absorbent, odor-eliminating, antistatic, and flame retardant. Its made from cotton and polyester, and is seamless. This is really good for space missions becuase alot of bacterica, odors, etc can get really, really bad a tiny space shuttle.

 As you can see astronauts have to change there whole life style while there in space. You've learned the difficulties of everyday tasks, such as eating, sleeping, and exercising.
