Let's imagine a near future where mankind starts to expand into the solar system. For various reasons, some humans start to be born and raised in space, in zero gravity and micro-gravity.
What characteristics could these humans have?
For a list of negative points, it's easy to find:
- Weaker immune system
- Muscle atrophy
- Bones atrophy
- Motion sickness on earth
- Eyesight affected
- Puffy face and so on
So basically, life on earth is going to be hell for these people, and they will need extended medication just to be able to survive. I want to imagine reasons that could counterbalance these points and make these persons extremely valuable to a space program. I want to point out that I'm not necessarily looking for very realistic answers, (I intentionally avoided using the hard-science tag) but more for coherent ideas.
I came up with some ideas already:
- Most of the negative points above wouldn't be a problem in zero gravity
- Better 3D motion
- More tolerant to nervous stress
- Higher IQ
- Shorter sleep time
So my question is: What ideas can you find to develop this list? What traits could make a human better suited for space exploration?
