Concordia should enable the scientists to achieve astronomical studies, taking advantage of the long and dry polar nights.
Also, isolation lasting months rather than just 10 days, can be of use to study human psychology.
Meanwhile, the MS, after Devon island, has gone to Utah, perhaps to Iceland too and many other countries. But how long lasts the mission of one man? I asked the question to Vladimir Pletser once (I'm reading his book "En avant Mars"; He said that a 550 days long stay in a place like Devon for a single crew is not possible as the volunteers have jobs elsewhere and have to take the time from their vacation.
Concordia is very different.
