This is my Mars Base. It includes oxygen extractors and solar panels. It is labeled with the following:
L1 This is the main household or lobby of the base. It has a bedroom, kitchen, sitting area, and dining area. It also has storage for food.
R1 This is a small research lab designated to non-dangerous testing such as plants and water extraction.
R2 This is a large research lab designated to all types of testing. It has a upper silo with one way vents to allow fumes and gasses out of the main testing area.
W1 This is a storage tank for water.
O1 This is a oxygen storage/extraction silo.
G1 This is a garage with two ports one for the mars rover, and another for supply ships (food and part)
The solar panels are mounted atop the tall pole (square piece on smaller pole)
