KOROLYOV, Russia (Achieve3000, March 8, 2011). Have humans just landed on Mars? Not really. But an experiment in progress is showing space officials just what a mission to the Red Planet might be like for a crew of astronauts. After spending 257 days in a locked, windowless steel capsule, six researchers on a mock trip to Mars recently "landed" on a simulated version of the planet.
During the mock landing on February 14, 2011, some of the crewmembers came out of their cramped quarters in heavy spacesuits. They trudged into a sand-covered room that was meant to approximate the surface of Mars. After planting the flags of Russia, China, and the European Space Agency (ESA), crewmembers took "samples" from the ground and conducted artificial scientific experiments. Meanwhile, the remaining crewmembers were in virtual orbit inside their mock spaceship.
The pretend Mars landing represented the halfway point of Mars500, an experiment that began in June 2010 and is scheduled to run until November 2011. By that time, the crew will have spent 520 days on the mock mission. Officials want to see how humans cope with the constricted, isolating conditions of space travel in preparation for a real-life trip to Mars, a mission that would take well over a year to complete.
So the crew, made up of Russians Alexey Sitev, Sukhrob Kamolov, and Alexander Smoleyevsky; Frenchman Romain Charles; Italian-Colombian Diego Urbina; and Wang Yue from China, is spending the experiment on a capsule that is similar to a spaceship—even though they are not leaving Earth. The facility, which is in Russia, includes living compartments the size of a bus connected with several other modules for experiments and exercise. Crewmembers have a supply of canned food, made up of the same items given to the crew of the International Space Station.
The Mars500 crewmembers have been sealed inside their chamber, except during the mock landing. They have personal contact with one another and no one else, although they can use technology to communicate with outsiders, just as a real space crew can. The crewmembers communicate with the organizers and their families via the Internet. However, the Internet connection is delayed and occasionally interrupted to imitate the effects of space travel.
Having recreated the atmosphere of a space flight to Mars, officials are anxious to see how the crew reacts to the isolation of it. Psychologists say that the long period of confinement will put the team members under stress as they grow increasingly tired of one another's company. Psychological conditions can be even more challenging on a mock mission than a real flight because the crewmembers won't experience any of the joys or dangers of actual space travel. Christer Fuglesang, an ESA astronaut who took part in two shuttle missions and made five real spacewalks, says the 18-month duration of the experiment will strongly challenge the participants.
"What they must miss, I'm sure, is the interaction with their families and friends," said Fuglesang.
The organizers of Mars500 have said that the experiment could be interrupted for medical or technical reasons, or if some of the participants demand that it be stopped. So far, however, the crew has been coping.
"After a couple of weeks, they were really a team, certainly with some temporary ups and downs of individual crewmembers," said Martin Zell, the ESA official who is overseeing the experiment. "A big challenge is missing daylight.... They also have to live with the food [that] they have onboard and with the air [that] they have onboard."
Crewmembers are learning one another's languages, watching movies, and playing chess in their free time.
This bodes well for a real mission to Mars. A trip like that is decades away because of huge costs and massive technological challenges. One of those challenges comes from the notion of sending humans far from Earth for the first time. Deep space has exploding stars, black holes, and more. All of these may give off potentially harmful radiation. Space agencies would need to create a shield that would protect humans from radiation.
In January 2010, President Barack Obama said that he foresaw sending astronauts to orbit Mars by the mid-2030s.

Here is an excerpt from page 2 of the Article. The Mars500 experiment was extremely demanding for the participants. Select five sentences with information that provides evidence for this claim.
In the end, the experiment was a success.Even though the researchers knew they could abort the simulated trip if necessary, all of them completed the entire 520-day stint.
"Now we can go forward and plan to go to Mars and move confidently," said crewmember Romain Charles of France.
At their first news conference after leaving their close quarters, the crewmembers appeared energetic and excited.They were unanimous in their sentiment that they were glad the challenge was finally over.Cosmonaut Boris Morukov, the mission chief, said the second half of the simulation was the most difficult.He said the lengthy confinement without daylight and fresh air put crewmembers under increasing stress, as did the monotony of the daily routine.
The crewmembers said they coped with the fatigue and stress of isolation by doing exercises, reading books, and endeavoring to learn foreign languages.They also spent time watching movies, playing computer games, and celebrating holidays together.Crewmember Diego Urbina also credited social networks with helping to alleviate the pressure.
