A journey to Mars would take up to two years—more than twice as long as previous space missions—and would be spent largely under conditions of microgravity. On p 1441 Fong considers the effects of prolonged weightlessness on the human body. How best to deliver the crew to Mars in an optimal state for landing and subsequent exploration is a matter of some debate. One avenue that is being explored is the use of artificial gravity during the space flight.
