One of the problems is how nearly two years of cosmic travels would affect the crew of a space vehicle. Another one, just recently raised by scientists, relates to the dangers posed by microbes and bacteria that the astronauts may involuntarily take with them to the Red Planet. Cross-contamination issues aside, microorganisms could wreck havoc in a crew, by acting in a double, roundabout manner. First, an infection would considerably weaken the space travelers' immune systems, which would make them more susceptible to outside influences. Secondly, the virulence and growth of microbes is significantly boosted, healthcare experts say. Even minor infections are something to be taken very seriously in space, as t!
