A group of NASA-funded researchers are entering an isolated geodesic dome perched on a remote Hawaii volcano to study human behavior for future long-term space exploration, including future trips to Mars. The six crew members entered a dome structure on the Big Island's Mauna Loa Thursday, Jan. 19, 2017, and will spend eight months together in the research facility without physical contact with any other human beings.
