Hostile and Closed Environments, Hazards at Close Quarters

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

A spacecraft is not only a home, it’s also a machine. NASA understands that the ecosystem inside a vehicle plays a big role in everyday astronaut life.

Important habitability factors include temperature, pressure, lighting, noise, and quantity of space. It’s essential that astronauts are getting the requisite food, sleep and exercise needed to stay healthy and happy. The space environment introduces challenges not faced on Earth.

Technology, as often is the case with out-of-this-world exploration, comes to the rescue! Technology plays a big role in creating a habitable home in a harsh environment and monitoring some of the environmental conditions.

Astronauts are also asked to provide feedback about their living environment, including physical impressions and sensations so that the evolution of spacecraft can continue addressing the needs of humans in space.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including hostile and closed environments, like the closed environment of the vehicle itself. To learn more, and find out what NASA’s Human Research Program is doing to protect humans in space, check out the “Hazards of Human Spaceflight" website. Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of hostile and closed environments with Brian Crucian, NASA immunologist at the Johnson Space Center.
