Human Health Countermeasures
The Human Health Countermeasures (HHC) element seeks to understand the physiologic effects of spaceflight and develop strategies to mitigate those with detrimental effects on human health and performance.
Learn More About Our Research
The Human Health Countermeasures (HHC) element provides biomedical expertise for the development and assessment of medical standards, vehicle and spacesuit requirements, and strategies that ensure crew health during all phases of flight.
If being in space is found to affect crewmember health in negative ways, HHC is tasked with developing safeguards to mitigate those effects.

Space Nutrition
Astronauts require food that is nutritious, appetizing, long-lasting, easy to make, and more. We strive to continuously improve the quality of space food and to satisfy the dietary needs of crew members on increasingly longer and more distant spaceflight missions.
Focusing on Crew Health
From studies that examine bone and muscle loss in space to attempts to characterize the microbial environment of the International Space Station, NASA scientists are examining how to best ensure crew health and safety.
