>>511205626 (OP)won't happen in your lifetime kid, there are a dozen if not more of problems
>human body and gravityGravity is much lower than Earth, so will affect your body (Cardiovascular System, Bones and muscles etc) so you will need to work harder(exercise) and take more suppliments just to go by(but won't be enough), that's without 12-14 hours or more of work per day you need to do just to keep the base/colony running
>energyyou will need a nuclear reactor/fusion reactor to have energy there, you can't relied on Solar/wind, there are desert storms that will go on for weeks or more, so Solar will be useless and Wind will be risky duo to powerful winds
>Dust stormsthe storms on Mars can cover continents in size and going for months or even more, so you need to survive during those times without backup from Earth
>radiations and resourceshave fun mining or doing something outside while there's a storm and you need to wear a suit 12 hours or more duo to radiations and temperatures
Mars is just a dream right now or in the near future, maybe will happen in 50 years or more
