Good luck Spiro! Sounds like a harsh but cool experience, not for me but I can see why it would be attractive to many people
There will only be 4 people at first and they will be carefully chosen based on their social dynamics. They will be put together for 3 months at a time in the desert every 2 years and undergo many other group tests for 10 years before ever leaving for Mars. So if they can’t get along they don’t go together.
I am already planning what will be in my application video/letter.
I am quite serious about wanting to go myself, and am about 90% sure I will apply as soon as possible. I look forward even to the training and exercise—it would be nice to get back into shape.
