Simulated Mars Mission 'Returns' After 520 Days

On June 3, 2010, a team of six volunteers began the Mars500 experiment: they were locked into a cluster of hermetically sealed habitat modules for the duration of a simulated mission to Mars lasting 520 days. "During the ‘flight,' the crew performed more than 100 experiments, all linked to the problems of long-duration missions in deep space. To add to their isolation, communications with mission control were artificially delayed to mimic the natural delays over the great distances on a real Mars flight." The simulated mission has now come to an end. The crew managed to stay healthy and sane, and they've emerged from isolation to be reunited with their families. The ESA's Mars500 page has further details on the experiment, and they've posted a video summarizing the 'trip.'

    520 days is definitely enough to complete a round-trip Mars mission. This experiment suggests that you can successfully go "there and back again" without making your astronauts lose their mind.

      British sailing Man-of-Wars would be out of contact with land for months at a time. American Whalers reported being at sea for three years in pursuit of the South Sea sperm whales. Those men did perfectly fine. These ships sometimes had hundreds of people and the men did not go bat shit insane.

      That is just wrong. Those ships were not riding the seas for three years with no contact with land. They had to stop and times to provision, unload cargo, perform repairs that would require calm waters and materials from land. So perhaps they were away from"home" for three years, but natives in the south pacific may from time to time had blue eyed babies. There was also rampant "buggery", discipline through fear and violence and death was treated a part of the risk, not the exception. Out of a hundred crew members, if you lose one or two on a cruise you just re-hire in port or just make do. Lose a crew on a 5/6 man space mission has way more impact on every aspect of the mission.

      Someone else mentioned subs that go on patrol for 5-6 months as a closer example to this experiment. In that I slightly agree, but 5-6 months is not 520 days. Subs are equipped with some of the best food products for meals, vast media libraries, and a military structure that (on the surface) sets a standard of behavior. No navy has tried to run a sub for 2 years non stop underwater. Now that may could close to an ideal on earth experiment.

      It would be easy to say "just send em up and see what happens", but when you are talking Billions of dollars invested with no direct return? I can understand a step wise approach. Whaling ships were a lot cheaper to build (thus lose) then a Mars spacecraft.

      Actually, that's less likely to happen. Most likely is that one of them would go batshit insane and the mission gets aborted.

      The primary reason is humans are social creatures, and interactions with others are necessary for survival (it usually happens often enough for most people that no one thinks about it). Hell, even your old timey ships rarely sailed for 2 years without stopping for resupply somewhere (see "social"). Sure it may not be with family, but any contact is better than none. (With a Mars trip, the delay makes real-time communications impossible).

      And like others have said, there's a lot of discipline and justice issued - "walking the plank" is not a metaphor but a common punishment. New crew can always be hired in the next port (which wouldn't usually be too long).

      Basically, the experiment is if you put 5 people in a trailer with proper simulated contact - will they get cabin fever? And what kind of crew make up will lessen the chances? Long-distance discipline is much harder, so do you run the crew as a strict military unit, or as a loose organization?

    My memory is a little hazy on the specifics, but I will share this too. Every now and then, the boat would send some people over to the flooding trainer. they covered the basics on how to apply various flood stoppage techniques. If I recall correctly, they certainly didn't recommend putting your hand/body into any fluid streams. I think the primary concern was so much that you would have a liquid laser in the case of a fine stream, similar to what happens when you put your thumb over a hose, but more that if you had anything in your hand that would then get knocked out and then become a fast moving projectile.

    This was particularly true for one technique that was used to stop a rupture from a pipe. If the hole/gash in pipe as the right size, then they had these curved metal pieces with rubber on one side that would match the contour of the pipe. The idea is then to put this piece of metal across the pipe, apply pressure , which then would be sealed by the rubber. It was amazing at how effective it was in stopping the leaks in the simulator. The problem being, if you did this wrong, this would be a lethal projectile. The idea was to then pre-secure this metal patch a few inches away from the pipe with some metal banding and then inch it down the pipe until it covered the hole. Then the final compression was applied to the metal banding. When everything was done, you would hardly know there was a leak there.

    All in all, I thought this was the best, funnest, and most practical training that I think I have ever had. Granted, if this was happening while I was on the boat in a real situation I would probably not find it so fun, but I wouldn't be useless either on what to do if needed.
