Living Away from Earth

Abstract

Reproduction and the development of a ‘normal’ next generation is one important hurdle for moving away from Earth; however, it is just the beginning. Nothing is known about long term multi-­generational affects, of not only space μg, but in the reduced gravity fields of the moon and Mars or other planets. Another unknown is the long-term effects of extraterrestrial radiation; solar radiation from the Sun and cosmic radiation from outside our Solar System. Until we begin to live on other worlds, we must rely on conjecture and best estimate from what is known. Although radiation is a big biomedical concern, it can be blocked by insulation or deflection while in space. Alternatively, it can be avoided by locating living/working quarters under the surface of the moon or Mars to provide shielding. Living underground, settlers will be safe from radiation. This approach can work for living and research quarters, but explorers and settlers will still need to venture out on the surface. There they will be exposed to increased levels of radiation.
