2.4.4. Radiation vs. Illumination/Views
· Three major sources of radiation: Solar Wind coming from the Sun’s direction, Cosmic Rays coming from all directions, Solar Flares and Coronal Mass Ejection coming from the Sun in punctual storms.
· Protection to Solar Wind and Cosmic Rays can be achieved by a 30cm thickness of Martian regolith; water tanks or materials with large amounts of hydrogen.
· Solar Flares and Coronal Mass Ejections will need specific shelters.
· Illumination and views can be achieved with special windows with 7cm water thickness, by creating water mirror surfaces that reflect light or by assuming a future development of radiation shielded plastics.
