Hawaii's Mars Simulations Are Canceled (theatlantic.com)
The dome where crew members practiced red-planet missions will now be converted to a simulated moon base. Excerpt from a report: For the last five years, a small Mars colony thrived in Hawaii, many miles away from civilization. The Hawaii Space Exploration Analog and Simulation, or HI-SEAS, was carried out in a small white dome nestled along the slope of a massive volcano called Mauna Loa. The habitat usually housed six people at a time, for as long as eight months. They prepared freeze-dried meals, took 30-second showers to conserve water, and wore space suits every time they left the dome. To replicate the communication gap between Earth and Mars, they waited 20 minutes for their emails to reach their family members, and another 20 to hear back. Sometimes, as they drifted off to sleep, with nothing but silence in their ears, they really believed they were on Mars.
In February of this year, something went wrong. The latest and sixth mission was just four days in when one of the crew members was carried out on a stretcher and taken to a hospital, an Atlantic investigation revealed in June. There had been a power outage in the habitat, and some troubleshooting ended with one of the residents sustaining an electric shock. The rest of the crew was evacuated, too. There was some discussion of returning -- the injured person was treated and released in the same day -- but another crew member felt the conditions weren't safe enough and decided to withdraw. The Mars simulation couldn't continue with a crew as small as three, and the entire program was put on hold. [...]

This was nothing more than a study of the mental/emotional effects of being on Mars, as well as a study of how some of the mechanical and procedural systems might work on Mars. They got plenty of data on that.
For a first run, this was about as good as one could hope, but with systems that haven't yet been refined for the unique challenges presented by living on Mars, there's no good reason to let people suffer and potentially die with such an early iteration.
