Mars One is an initiative to create a human settlement on Mars, with the first crew expected to depart earth in 2024. Although I can't imagine applying to go on a one-way mission to Mars, I'm fascinated by the concept and intrigued by the process.
Needless to say, taking a job like this is no small commitment - you are literally giving your life to your job, and the first crew of four's commitment and preparation will determine the success of a program to colonise another planet. (No pressure).
What's particularly interesting to me is the selection criteria - although there are some age requirements and no doubt health requirements, the five key criteria are Resiliency, Adaptability, Curiosity, Ability to Trust, and Creativity / Resourcefulness. Technical skills can be taught, even on a scientific mission - but the right persona is critical. We see this playing out in all different industries, all round the world - what differentiates a competent member of the workforce from an exception performer is rarely a technical skill - but we typically source for and develop on technical skill alone.
