Mars mission may shorten astronauts' lives by 2.5 yrs: Study
A research presented at a Moscow conference has estimated that a round-trip mission to planet Mars may shorten astronauts' lifespan by 2.5 years. The report cites prolonged exposure to heavy solar radiation as the reason for it. The researchers suggest that using sleeping bags with water insulation and consumption of mineral water will reduce the harmful effects of the radiations.
