1.2.4. Crater base
· Partially protected against radiation sources (SW). Base level below horizon.
· Easy to set up. Minimum excavations needed (for foundations only).
· Difficult access to other Martian destinations. Crater exit structures needed.
· Possible poor quality of ground due to crater’s meteoroid impact origin.
Considering future evolution on material shielding against radiation, the option chosen is the Surface Base that will provide maximum benefits to the first phase Gen 1.5 and future growing of Gen II. However excavations will be required and thus the project takes advantage of that situation by opening some courtyards. Detail explanation on that can be found at the Gen1.5 Settlement Description Chapter.
