Final considerations

The building of LEDA will initially involve the setting up of a lunar mining facility which will then provide the assembling site with current and sufficient amounts of materials.

 

LEDA will be built using both materials mined from the Moon and materials brought from Earth (such as some volatiles) and will be assembled in the Lagrangian point L5.

 

The basic shape of LEDA will be that of a torus. Some secondary structural elements, such as the central body, the four main elevators and the two symmetrical large mirrors will enhance the settlementís functionality.††

 

LEDA will measure 9022 m in diameter. The height of the residential segment will be of 500m, while the diameter of the central body will measure approximately 1020m. Two main mirrors will reflect the solar light both onto the solar panels and the small adjustable mirrors lightening the artificial sky of the Settlement.

 

The industrial area of LEDA will function within the 0 gravity center and will be permanently supplied with the raw materials obtained from mining the lunar surface and the different Near Earth Objects.††††

 

Materials will be exploited and processed using different extraction and separation methods. Their characteristics will be improved in order to obtain more reliable building materials.

 

Radiation levels onboard LEDA will be measured using both common measuring devices and the latest technological developments in this field. Radiation will be minimized using different shielding methods. The one we foremost propose is the Electromagnetic shielding.

 

Gravity onboard LEDA will be artificially recreated by rotating the torus around its symmetry axis. The gravitational constant within the residential area will be identical to that on Earth.

 

By studying the effects of artificial gravity on atmosphere we propose an optimum air pressure inside the torus and a suitable chemical compostion of the atmosphere.

 

Alimentation onboard LEDA will consist in both vegetal and animal food and will efficiently satisfy all the needs of the human organism by providing a complete utrient composition.†††

 

Water will be obtained from simple elements (H2 and O2) or from lunar ice. It will then be chemically treated, used and recycled. Its chemical composition will be permanently monitored to avoid contamination.

 

Waste onboard LEDA will be recycled, processed and reused in the different industrial activities.

The different risks will be minimized by permanent monitoring of the human activities and by creating a strict set of norms and rules.

The basic power supplying system of LEDA will use solar energy.

 

Conclusively, LEDA will initially be home for 250 000 colonists aged 5 to 70. The employment grid will firstly take into account the basic needs of the Settlement, focusing on the building and life maintaining activities.

 

By artificially recreating the life conditions found on Earth (light, gravity, atmosphere, water, climate), by providing sufficient amounts of energy, by setting up a productive and economically feasible self-sustaining industry, by minimizing all unpleasant and unhealthy factors (vibration, odor, noise, toxicity), by assuring a proper alimentation and an effective social system the minimum needs of the orbital population will be satisfied.††

A democratic government, an efficient and varied system of social facilities and an eligible infrastructure will provide a solid support for the development of a healthy and civilized society.

 

Although, our generation is familiar with the last discoveries that manís greater and greater wish for knowledge has generated, the issues which the proposed subject of this project deals with have such complexity that a lot more space would be needed for them to be fully debated.

We were born after that unforgettable step of Neil Armstrong on the Moon, so small for a man but such a giant leap for mankind.

To think that man could live in other places of the Universe, places that could be adapted to his needs can really become a challenge for our generation.

But the issues raised by fulfilling such a challenge, imply large spectrum of knowledge, dedication and imagination.

It is difficult to predict a deadline for the achievement of such an ambitious dream, but when it will come true, just think of how many of our problems today will find their solutions!

We canít end our presentation without thanking you for the opportunity you have offered us to concentrate our creative imagination on such daring, exciting, though overwhelmingly vast subject.

There is no doubt that the subject is still open to more through study and research, but one thing is certain: working on the project has definitely made us reassess our options regarding our future professional choice!
