What material is specified for burying structures to create effective mass shielding against galactic cosmic rays?
Answer
Regolith
Given the high radiation threat on the Martian surface, the consensus points toward extensive technological intervention utilizing deep subsurface habitats or heavy artificial shielding. To effectively block dangerous radiation, such as galactic cosmic rays and solar particle events, structures must be buried beneath several meters of the local surface material, which is specifically identified as regolith. This mass shielding is essential for creating the necessary safe havens for pregnancy and gestation.
