What the point? The whole idea of convict settlements in space is at best silly and at worst shows a fundamental misunderstanding of what is required for space settlement.<br /><br />Firstly is is based on a false historical parallel. Convicts were used to help establish terrestrial settlements as cheap labour. This was in a pre-industrial era. We have since had two industrial revolutions, mechanisation and information technology. There is simply no need for convicts in space.<br /><br />Secondly, it is based on a complete lack of appreciation of the skills required for Mars settlements. Those going will need skills in geology, meteorology, geophysics, geochemistry, mining geology, metallurgy, materials science, hydroponics, medical technology general surgery, space medicine, nursing, physiotherapy, midwifery, nursing, solar technology, nuclear engineering, sanitation, waste disposal, propulsion, automotive engineering, civil engineering, aquaculture.... the list goes on. How many convicts have these skills?<br /><br />Thirdly, it underestimates the type of character needed for such an understaking. Being skillful, intelligent, experienced and highly educated will not be sufficient. So far from earth and dependent utterly on the function of complex, interdepent technologies and the people required to run them, you will need people who are brave, compassionate, moral, ethical, empathetic, and utterly trustworthy. How many convicts meet these requirements?<br /><br />Fourthly, with a whole planet of volunteers to chose from, why send people who don't want to go?<br /><br />Convict settlement of Mars is SF and bad SF at that. <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
