Five steps to colonising Mars – BBC Future

As a commander of a space colony on Earth, Tarvin is one of the few people to have any experience of overseeing a Mars base. Its certainly not a Star Trek-style military environment, he says. Its a small group of highly motivated people and it really doesnt take much effort to manage them.

A government also needs all the structures that go with it. Any new society needs an economy as well as systems to maintain the habitat, provide employment, health, childcare, social care and education. In short: Mars needs bureaucrats.

The first Mars settlers will be living in the capsules they arrive in, perhaps augmented by a few extra capsules sent ahead and maybe some inflatable domes. But just as settlers will be utilising local resources for water, food and energy, they will also hope to use local materials to build a larger colony or even spin-off colonies.

At the very least, it would make sense to use Martian rock to bury the habitats to help shield occupants from radiation. Later, the surface could be drilled to form caves or rock could be excavated for building materials just as we build houses from stone on Earth. It might also be possible to extract useful minerals for metals or glass.

Robert Zubin, the president of the Mars Society, is one of the leading exponents of terraforming Mars transforming the planet from an airless, barren world to an oxygen-rich green and pleasant realm with a fully functioning ecosystem.
