Space hazards refer to various dangers that can affect spacecraft and astronauts in outer space. These hazards include cosmic radiation, which comes from the sun and other celestial bodies, and can pose health risks to humans. Additionally, micrometeoroids and space debris can collide with spacecraft, potentially causing damage or destruction. Another significant hazard is the lack of atmosphere in space, which means there is no air to breathe and extreme temperatures can occur. Solar flares can also disrupt communication systems and pose risks to both astronauts and equipment. Understanding these hazards is crucial for safe space exploration.
