Russia will start an experimental program for preparation for flights to Mars in 2006, said Anatoly Perminov, head of the Russian Space Agency Roscosmos. “The agency is not planning a manned flight to Mars until 2015, although we will start an experimental program at the Institute of Medical and Biological Research next year,” he told the Voice of Russia state-controlled radio station. “An international six-men crew will conduct a simulated 500-day flight to Mars.”
