Brian Resnick who is a reporter at VOX shares a list of several ways a person could die trying to get to Mars.
NASA and private space companies like SpaceX are working very hard to get humans to Mars, but this whole endeavor is very risky. There are many ways you can die on to the trip and the risk starts from the launch.
