Human race requires several essential conditions, a gravity environment, substances, and shielding for long-term stay on the Mars. Water and air are indispensable substances for human life support. Shielding is necessary for cosmic rays and meteorites. Moreover, if human race visualizes the artificial sea, which brings mental stability and gives space for safety lives to them. Under low gravity condition, human race has difficulty of health growth and physical retention. It may cause of human race has a body which cannot stand on its own feet. This may promote division of human race and furthermore it may cause of conflict is concerned. As a solution for this task, suggests that to use artificial gravity by centrifugal force due to rotation. To add it to Martian gravity is defined to create a similar gravitational environment of the Earth. For the material task, there are large amount of water and carbon dioxide and trace amount of nitrogen on the Mars is conceivable. Therefore, human race needs to create a section for living area on the Mars.
To suggest the Mars glass city is constructed by two-hundred-meter height rotating facility, is including its upper canopy part, a flared-skirt-shape bottom part, and an underground part. The residential area is separated by a part which is built on the Mars ground surface directly, a rotating artificial gravity area, and a skyscraper which also served as canopy steady braces. A rotating to generate gravity part is located only its bottom side. A heliport, a hub, for a sky transportation system between other facilities is placed on the top of the facility. The artificial gravity facility is holding water, this condition occurs its surface rises along the side wall. Inside of this facility can see rich water from everywhere by this phenomenon. Human race’s secure feeling is included by the Mars glass city has enough water and visually see it.
The internal pressure of artificial gravity facility is one atm on the Mars. The Mars atmospheric pressure is dilute, about 1/100 of the Earth, therefore its internal and external pressure difference is nearly one atm. This becomes 10t / m2 artificial gravity facility is required strong tension for suppressing all itself. The ground and horizontal direction are done with a tension ring. Expanding wires to the ground is come from the underground, which is deeply dived into it. The wires are connected at underground of the artificial gravity facility and they apply reaction force to the ground.
The facility is designed a double dome structure. Its exterior is mainly constructed as capable of withstand flying objects from space. A moistened super absorbent polymer is located inside of the artificial gravity facility for cosmic ray shielding. Considering by constructing the artificial gravity facility on the Moon, the Mars, and asteroids, insures for human race space development warranties to support comfortable long-term stay in space.
