Some of the facts we found was that in space, it is very cold and our spacesuit will help it keep the Mars tourists warm.We also found that the bones get weaker because of bone loss,this happens of the cause of less gravity. According to NASA space radiation can affect the health of people that go to space, astronauts could also be killed by the space radiation. To protect the astronauts in space for radiation NASA uses special material, altitude and inclination of the space craft to reduce the cause of radiation. All of these things could help us with our space suit. According to the Environmental Protection Agency (EPA) any living tissue can be damaged by ionizing radiation. Radiation can also cause cancer and that is considered the primary health affect from radiation exposure. The DNA can change because of the radiation and that is called mutation. Radiation is a really big problem for the people who are going to mars.
