Russian cosmonauts imitate landing on Mars
Italy’s Diego Urbina and Russia’s Aleksandr Smoleevsky have made their first steps on the Martian surface – at least virtually. They have taken samples of Martian soil and measured the magnetic field, as well as planted the flags of China, Russia and the European Space Agency.
Mars 500 may be a simulated mission, with the planet's surface modeled in the Moscow Region, but the “space walk” was monitored by Russia's real mission control.
The experiment is nearing its mid-point. After the volunteers spent more than 200 days simulating the flight to the Red Planet, they have been divided into two groups – one staying on board a module which is simulating a flight in Martian orbit, and another one sent to land on “the planet’s surface”.
Three volunteers are going to stay “on the planet” for a month, during which they will conduct three “Martian spacewalks”.
After this part of the experiment is over in 30 days, the three will be reunited with the rest of the group and begin their journey “back home” which will take another 200 days or so.
The 500-day experiment, which started last June, is designed to monitor the physical and psychological demands of deep space travel. And Christer Fuglesang, an ESA astronaut, says the distance makes it very difficult for the participants to cope:
“From the space station you can actually call home and talk to your family. That really helps you. But they [those en route to Mars] cannot do that… They are so far from Earth that even radio signal takes many minutes [to reach].”
“The experiment mostly focuses on medical and biological problems,”
said Anatoly Grigoryev, vice president of the Russian Academy of Sciences.“We are trying to better understand how a human behaves in these unusual conditions, when a small group of people works together in a contained environment. I think it's very important that the Mars-500 mission has an international crew. They are a single entity, and they became a real crew, perhaps, in the first month of flight.”
“They work very efficiently. They've managed an emergency situation. And we hope they'll be as efficient during these experiments on the surface of Mars,” Grigoryev added.
The six volunteers include China’s Wang Yue, two European citizens, Diego Urbina and Romain Charles, and three Russians, Aleksandr Smoleevsky, Aleksey Sitev and Sukhrob Kamolov.
