Research shows that there are high levels of radiation in outer space where astronauts are not protected by the Earth’s atmosphere. In fact, the longer the mission, the higher the risk of death by cancer. This project indicates that during a space travel, no matter if you have radiation detector equipment or not, the human body is always the first one detecting the radiation. In most cases your body won't react to the radiation immediately, unless the “cancer” is telling you. The aim of this project is to create a discussion on how society perceive astronauts, are they heroes or mice?
