HONOLULU (AP) — A group of NASA-funded researchers are poised to enter an isolated geodesic dome on a Hawaii volcano to study human behavior for long-term space exploration, including a planned voyage to Mars. There will be no physical human contact with the outside world, a 20-minute delay in communications to simulate the time it takes for messages to reach earth from Mars and the team will be required to wear space suits whenever they leave the compound. The crew will conduct daily tasks including geological and mapping studies, but will also be required to do more domestic tasks like cooking and cleaning. The other team members include engineers, a computer scientist, a doctoral candidate and a biomedical expert. The experiment quickly spiraled out of control as the habitat failed to maintain safe levels of carbon dioxide and the crew grew discontent. Furthermore, man-made disasters like climate change or natural catastrophes such as an asteroid hit could force a human exodus from Earth.
