NASA’s Human Research Program: Three Steps to Mars
Sending astronauts to Mars is the next giant leap of human space travel. In preparation for a trip to the Red Planet, NASA is taking a stepping stone approach to studying the health effects of human spaceflight using Earth-based analogs , the International Space Station, and lunar missions under the agency’s Artemis program.
NASA’s Human Research Program, or HRP, conducts research and develops countermeasures for five of the hazards of human spaceflight: radiation, isolation and confinement, distance from Earth, microgravity, and hostile/closed environments. These hazards pose risks to astronaut health and performance, and NASA aims to understand and manage those risks through research at each step, gradually moving farther from Earth using analog, space station, and lunar mission studies.
