2.4.1. Gravity vs. Indoor Pressure
· Gravity is about 38% of Earth’s.
· Atmospheric pressure is very low while indoor areas will be pressurized at 60kPa, meaning a high pressure difference between conditioned indoors and outdoors.
· The major structural problem for a conditioned space on Mars is holding the inside pressure, even though the buildings should also stand on without inside pressure during their construction or in case of an accidental loss of pressure.
· The best shapes to stand inside pressure are cylindrical and spherical as they homogenously distribute pressure on their perimeter.
