Mars One wants to send humans on a one-way trip to the Red Planet in 2022. Four individuals will be selected out of the more than 100,000 that have already applied, according to the Dutch nonprofit. But would members of such an expedition, estimated to cost $6 billion, survive the trip?
But a one-way trip to Mars would face an enormous number of technical and practical hurdles that aren’t close to being figured out. NASA’s intrepid rover Curiosity has started addressing one of the questions: radiation exposure on the journey.
NASA has been exploring some of the risks involved with such a long, pioneering journey. Scientists recently analyzed data sent back by Curiosity’s radiation assessment detector during the rover’s nearly 9-month journey through space and found a serious amount of radiation bombarding the spacecraft. How would humans fare in that scenario?
