Feld trip

Today we went to the planetarium and learned about the body and a litte about what it takes to be an astronaut.  We learned that your body has cells that fight off viruses.  To be an astronaut you have to go through multiple tests. They have to spin around in a machine to get used to the G forces in space. They also have to ride in the "vomit comet". You have to have years  of training befor you get to go to space.  When you are in space you have to work out to keep your muscles strong so you can walk when you get back to earth.
