Cần ít nhất bao nhiêu người để có thể định cư ở Sao Hỏa?

-----

Researchers (các nhà nghiên cứu) have revealed the best traits (đặc điểm) for the first human settlers (người định cư) on Mars.

Computational (tính toán) social scientists at George Mason University looked what they determined to be the four broad personality (nhân cách) types – neurotic (dễ bị kích thích thần kinh), reactive (phản ứng lại), social, and agreeable – and ran five simulations to see which would fare best on the Red Planet (hành tinh đỏ).

After a trial period (giai đoạn thử nghiệm) of 28 years, they found people with the "agreeable" personality type were most likely to last.

"Establishing a human settlement on Mars is an incredibly complex (vô cùng phức tạp) engineering problem," the researchers wrote in a newly-released paper published on the arXiv preprint server.

"The inhospitable (không ở được) nature of the Martian environment requires any habitat to be largely self-sustaining (tự duy trì).

...the researchers also found the optimum (tối ưu) number of people required to start rebuilding civilisation on another planet.
