HERC4, or the Human Exploration Research Center 4, is a facility dedicated to advancing human space exploration. It focuses on developing technologies and strategies to support long-duration missions beyond low Earth orbit, such as those to Mars or the Moon. The center conducts research on various aspects of space travel, including life support systems, radiation protection, and crew health. By simulating space environments, HERC4 aims to understand the challenges astronauts face and to create solutions that ensure their safety and well-being during missions.
