In Hawaii, a 6-Person Crew Begins a Year-Long Mars Isolation Experiment

The BBC reports that six volunteers have begun a planned year-long stint "without fresh air, fresh food or privacy" in a NASA simulation of what life might be like for a group of Mars colonists. The volunteers are to spend the next 12 months in the dome (11 meters in diameter, 6 meters high), except for space-suited out-of-dome excursions, where they will eat space-style meals, sleep on tiny cots, and keep up a science schedule. The current mission is the fourth (and longest yet) from the Hawai'i Space Exploration Analog and Simulation; you can read more about this mission's crew here.

They should have done it under water, if they insisted on Hawaii instead of Antarctica, which would have been a better choice (or at altitude on K2 or Everest, as long as it was a non-permanent installation). There's too much temptation to cheat, there's no real danger, and we already know that curing concrete will eat all your CO2 if you are stupid and don't seal it.

The only good choice fora Hawaii location other than "under water" would be "Inside a large SO2 cloud near a volcano, so that breathing the external atmosphere would get you dead".

[hey!]

To answer your question, smaller habitat, no experiment at maintaining atmospheric composition, outside excursions in "space suits" etc. Its not very much like Biosphere II.

As for why not under the sea or Antarctica I can give at least three reasons. (1) cost of building, transporting and maintaining the habitat; (2) all the support and research personnel live in Hawaii, above water; (3) the research objectives don't require putting the experiment in a dangerous or inaccessible place.

Now someday when we have an actual habitat design along with all the actual support systems we plan to send to Mars, a trial on top of a super high mountain would make sense as a kind of Mars analog. But we don't have such stuff to test so we don't need the Mars analog with all the expense and complication.
