Russia is planning a simulated mission to Mars to study the effects of such a voyage on the crew.
The 500 Days experiment, under development by the Russian Institute of Medical and Biological Problems, will isolate human volunteers in a mock space station module for -- as its namesake suggests -- a complete 500 days to study how a long mission to Mars might affect its human crew."Obviously, we're very interested in the results," NASA spokeswoman Dolores Beasley said of the long-duration study during a telephone interview. "It is a high priority for us."
During the 500 Days study, six volunteers will depend on a preset limit of supplies, including about 5 tons of food and oxygen and 3 tons of water. A doctor will accompany volunteers inside the module to treat illnesses and injuries. Volunteers will only be allowed to quit the experiment if the develop a severe ailment or psychological stress.
