Astronauts encounter five hazards as they journey through space. Recognizing these hazards allows NASA to seek ways that overcome the challenges of sending humans to the space station, the Moon, Mars, and beyond.
Humans aren't built to live in space, and being there can pose serious health risks. For space administrations like NASA, a major goal is to identify these risks to hopefully help lessen them.
Here are five of the most dangerous threats astronauts will face when traveling to Mars and beyond. Cosmic radiation, energy-charged atom fragments from the sun, and supernovae outside our galaxy can give astronauts anxiety, depression, and impaired decision-making.
NASA and other space agencies have studied the health of hundreds of astronauts over the past 6 decades, finding a wide range of impacts, including elevated long-term cancer risks from exposure to space radiation, muscle atrophy and bone loss from life in microgravity, and changes in vision.
Space travel poses a number of risks to health. Without Earth’s atmosphere and magnetic field to protect them, astronauts are exposed to space radiation, which can increase their risk for cancer...
However, traveling to space poses risks to the human body. Since NASA wants to send a manned mission to Mars in the 2030s, scientists need to find solutions for these hazards sooner rather...
The health perils of space travel start with the G forces felt by astronauts on lift-off, and continue with the exposure to hazardous space radiation and microgravity while in space.
Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight: Space Radiation. Isolation and Confinement. Distance From Earth. Gravity Fields. Hostile Closed Environments. Watch a playlist of videos to explain each hazard and to learn what NASA’s Human Research Program is doing to protect humans in space.
The nausea, dizziness, headaches and confusion can linger for days. “Puffy Face Bird Leg Phenomenon” develops, as blood and other bodily fluids rush to the upper body in low gravity...
The major health hazards of spaceflight include higher levels of damaging radiation, altered gravity fields, long periods of isolation and confinement, a closed and potentially hostile living...
