What Would be the Advantages and Disadvantages of Human Settlements on Other Planets?

                

                “Human Settlements on Other Planets” still sound like science fiction, but this could become reality in as soon as thirty years. Scientists from all over the world are preparing for the colonisation of Mars in 2050. They are aiming for hundreds of people to work and live on this planet. People started thinking about it ninety years ago, and, in fact, the colonisation of space has already started. There is only one more step to take, before this new era will change our lives.

        Possible psychological problems like agoraphobia or stress could be a barrier to the colonisation of Mars. Evidence for this phenomenon already exists: in one of the ‘Skylab’ missions, the crew stopped working, because it had too much to do. They started playing games and did not at work at all, for three days. If something like that happens millions of kilometres away from Earth, it would really be a problem. The whole mission could fail because the astronauts neglect the work they have to do. But not only stress, also isolation could become a real difficulty. The astronauts would be completely alone. They can not just go to a shop and buy something to drink.

        The different gravity on Mars could result in an increase in brain-size of the “colonists” – causing humanity to become “two-tiered” in terms of intelligence. Experiments in the Space Stations ISS and Mir, have shown that one effect of lower gravity is that more blood flows into the brain. The long-term effect of this process is an increase in brain-size. The people that are still living on Earth could become “sub-humans” for the Martians. Another effect of the lower gravity would be that the people on Mars would generally become bigger. Long-term astronauts on Mir grew about ten centimetres. On ...
