Meteor Images Test in class

Space is not as safe and empty as you might imagine. Dangerous meteoroids move at extreme speeds, thousands of miles an hour. Some even though they

are only the size of a grain of sand, can rip through a space craft. If we are to travel to mars, we must develop smart materials to combat the harshness of space. It's not only solid particles that space travelers need to worry about, cosmic rays are also a real risk and could potentially cause cancer by invisibly destroying vital DNA. If some how you were left unprotected in space or on the Martian planet surface, the gas in your lungs and the solutions in your blood stream would expand and kill you. For this reason a space suit that meets these survival needs must be fine-tuned.
