Over 200,000 people apply to live on Mars

Over 200,000 people have applied to live on Mars as part of an ambitious proposal by private foundation Mars One to establish a human settlement on the Red Planet by 2023.

Amongst the 200,000+ applicants are four who, according to the Mars One mission roadmap, would leave Earth forever in 2022 and arrive on Mars in 2023.

There are no plans for any of the settlers to return to Earth and the chosen few must come to terms with leaving Earth behind for the rest of their lives.
