Question
What are the health problems travelling on Mars?
Answer: Mars provides a harsh, alien environment, extremely cold and with a very thin atmosphere of carbon dioxide. Anyone living or traveling on Mars would require a robust life-support system to provide higher atmospheric pressure, adequate warmth, and such necessities (for us) as food and water. Two other aspects of the martian environment should also be considered. With no ozone in the atmosphere, the surface is strongly bathed in ultraviolet sunlight. This UV light would be lethal for exposed terrestrial life, but it is easily shielded by a space suit. The other danger is from ionizing radiation (cosmic rays), something that our atmosphere on Earth partially shields us from. Spacecraft currently at Mars are making measurements of this ionizing radiation. It is higher than on Earth's surface, as expected. Therefore it will probably be desirable to use a layer of dirt or some similar material to protect any long-term habitats. We should note that none of these challenges is any greater than those faced by the Apollo astronauts on the Moon, so we know that capable life support systems could operate on Mars, if and when we send humans there.
