    How will the human body adapt to life on Mars?

    The muscles in the human body have adapted to suit the gravitational force of Earth. With the gravity on Mars being 1/3rd that of Earth, how do you think the body will evolve?

    Assuming we create an environment with a habitable atmosphere and earth-like lighting and other environmental factors, then the only difference will be gravity. A 150 pound man will still have a mass of 150 pounds, but his weight will be 50 pounds.

    Regular exercise will probably be essential to prevent muscle atrophy and illnesses arising from that.

    It will be a very healthy environment for our joints - all aerobics will be low-impact.

    The effect on heart and blood pressure is uncertain.

    If people live there for years, we may have a whole new set of obesity problems.

    And what we truly can't know - if someone lives on Mars for years, could they ever become strong enough to return to Earth?

    Science fiction on this theme has been around since the 1950s, for sure.

      Astronauts, spending 3 months in space often are stretchered away when they land and spend time recovering from muscle loss. I would imagine the longer they are subject to low or zero gravity the harder it would be to return.

      Agreed, but 0.38g is very different from zero G. There is probably some threshold of gravity level that will allow the human body to remain easily adaptable to greater gravities. We'll never know until we try!
