Shielding Materials
Shielding materials are materials used to protect spacecraft and astronauts from the harmful effects of space radiation. These materials can be passive, such as metals and polymers, or active, such as electrostatic and magnetic fields. Passive shielding materials absorb or scatter radiation, while active shielding materials deflect or repel radiation. The effectiveness of shielding materials depends on their thickness, density, and composition, as well as the type and energy of the radiation. Shielding materials are essential for long-duration space missions, such as interplanetary travel and colonization, where astronauts would be exposed to high levels of radiation for extended periods of time.
