"Four Volunteers Begin Year-Long Mars Simulation in NASA Habitat"

NASA has locked four volunteers into a simulated Martian habitat for a one-year mission called CHAPEA (Crew Health and Performance Exploration Analog) to study the logistics and human psychology of long-term living on another planet. The crew will live, work, exercise, sleep, and perform experiments in the 1700 square-foot 3D-printed living space called Mars Dune Alpha. They will also engage in simulated spacewalks and follow a time-delayed communication system. The mission aims to gather insights on the physical and behavioral aspects of a Mars mission and prepare for future manned missions to the red planet.
