Space is not easy to live in. Objects float away if you don’t secure them. If you drink milk the liquid will float away unless it is in a container and you use a straw to get the liquid. Even going to the bathroom can be a difficult experience. Micro gravity is tough on a person’s body. If an astronaut stays in space too long, their bones start to break down. In this exercise, you are to design a space helmet for Pluto, Mars, and Saturn.
