One-way trip to Mars? Sounds exciting!

Do you want to be part of an expedition to the Red Planet? You can be part of a one-way trip to Mars but you have to wait till 2022. Mars One is planning to send humans to the Red Planet and more than 100,000 have already applied for it. But only four individuals will be selected, according to the Dutch organization. The big question is: Will members of such an expedition, estimated to cost $6 billion, be able to survive the trip?

The Obama administration has set a goal to send astronauts to Mars by the 2030s – but Mars One is much more ambitious, looking to send the four people chosen to actually colonize the planet. Applications have poured in and Mars One recently announced the start of its selection program. They say they’ve already passed the 78,000 mark besides the fact that the registration fee ranges from $5 - 73, depending on the country.

However, 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.But the radiation challenges aren't insurmountable, according to scientists.
