Monkeys for Mars trip

In addition to the effects of radiation, space scientists want to see how the monkeys react to
They won't utter Yuri Gagarin's famous phrase "Let's go!" But the monkeys of Sochi have already proven their worth as trailblazers in space - and now they are being groomed for a trip to Mars.
The macaques will be the first to experience the radiation that poses a big risk to astronauts - or Russian cosmonauts - on any flight to the Red Planet.
The Sochi Institute of Medical Primatology, at Vesyoloye near the Black Sea, has a proud history of involvement in the Russian - formerly Soviet - space programme.
"People and monkeys have approximately identical sensitivity to small and large radiation doses," explains the institute's director, Boris Lapin. "So it is better to experiment on the macaques, but not on dogs or other animals."
The institute will select macaques that may eventually fly to Mars before humans do. After two years of experiments the most suitable 40 monkeys will be sent to the Institute of Biomedical Problems in Moscow, where scientists study aerospace biomedicine.
Experiments on the monkeys will be carried out at the same time as the Mars-500 project. That project - due to start early next year - is aimed at simulating the conditions of interplanetary flight. Volunteers will have to spend 17 months in a mock-up "spaceship" in Moscow.
Monkeys may touch down on boulder-strewn Mars before humans
But a real expedition to Mars is not likely to happen for another 10 years at the very least.
Gruelling mission

Gruelling missionIn addition to the effects of radiation, space scientists want to see how the monkeys react to prolonged weightless conditions, isolation and a special diet of juices and pureed food.
Mars-500 director Viktor Baranov says 520 days "are enough for the flight to Mars - 250 days to fly there, 250 days to come back and a month for the landing on Mars".
Today Russia is one of the few countries where experiments on primates are carried out.
"Humanity sacrifices more than 100 million animals a year in the name of health and beauty. It's time to think of an alternative to experiments with animals," says Andrei Zbarsky of the international nature conservation group WWF.
