This chapter focuses on the demands of travelling to Mars. It considers factors such as the psychosocial aspects of living in a tightly confined space for a long time, the cost of a new space transportation system, and the need to set up a working habitat on Mars some time before a crew ship actually leaves Earth. It describes the effects of microgravity on microbes. In the early days of spaceflight, Russian scientists detected microorganisms growing in strange places on their spaceships, such as in crevices in the structural materials of cabin interiors and equipment. These microbes were busily degrading the structure of spacecraft components. Microgravity has also been found to increase the virulence of bacterial pathogens such asSalmonella typhimurium, which causes gastroenteritis. The remainder of the chapter discusses the risk of gas leaks, how the age and gender of the astronaut affects the health risks of prolonged space travel, and maintaining biological clocks.

Keywords:   human space exploration, Moon, Mars, interplanetary exploration, microbes, pathogens, Salmonella typhimurium, astronauts, gas leak, biological clocks
