This computer animated image shows a general view of the growing community of Gen 1.5.
The following graphic shows the implementation of theGen1.5 in the site, nearby Victoria Meridiani crater.
The following table shows the actual figures for the Gen1.5 Mars settlement:
3.5.5. Construction Staging
Prior the settlement construction, the settlers will live in some temporary habitats sent to Mars and mostly assembled. These buildings would be either vertical or horizontal inflatable structures with a small inflatable greenhouse to start the production of vegetables and agricultural experiments. After initial settlement construction is complete, the temporally habitats will remain in place as support buildings for further construction of the settlement.
Construction will be divided in different phases:
1. Temporary habitats, power and agriculture.
2. Surface ring roads.
3. Power and water facilities in the Industrial Area.
4. Mining and manufacturing in the Industrial Area.
5. Agriculture and Aquaculture in the Residential Area.
6. Private buildings and common areas in the Residential Area.
7. Underground ring road and pedestrian paths.
3.5.4. Industrial Area
On the rings that initially configure Gen1.5, four of them are devoted to the Accommodation Area. Three of them are just outdoor spaces with the material stockings on the mining and refining areas and the berms for the nuclear reactors. The fourth ring is dedicated to the conditioned spaces with “harder” industrial functions such as manufacture areas, maintenance and repair or MEP and Water/Waste Areas.
3.5.3. Accommodation Area
On the rings that initially configure Gen1.5, one of them is devoted to the Accommodation Area. Here, there are placed all the buildings with “softer” functions: private accommodation, common areas and greenhouses.
One of the main criteria during the development of the project was the use of multiple technologies and therefore geometries for each of the functions and buildings to implement in the settlement. This brings into the project an inherently eclecticism and look of disorder, an idea that is even strengthened by an apparent random when placing the buildings.
This effect is not considered as a negative value for the project due to the fact that the ring structure offers a larger scale order where every piece is submitted. However, buildings have certain order when placed into the ring: greenhouses and common areas are closer to the perimeter in order to provide easier access from the wheeled underground ring road to bring goods in and out. The private accommodation buildings, on the other hand, can be just connected between them with the pedestrian paths.
The Accommodation Area therefore includes 3 transparent greenhouses, 2 opaque greenhouses, 2 common area buildings (including laboratories) and 4 private accommodation buildings. These include three 8m diameter and 4 storey building with a total of 9 single apartments and 3 double, and one 12m diameter building and 3 storey building with a total of 3 single apartments and 3 double (that could be divided into 12 single). The final number of apartments is 12 single apartment and 6 doubles for a total of 24 people in the Gen 1.5 settlement.
In order to provide some extra light to the ground floor of the common area buildings and, on the same time, provide the perimeter ring circulation with some views and light, a courtyard is planned around them.
3.5.2. Transportation system
Transportation around Gen1.5 Settlement is provided in three levels:
· Surface transportation: wheeled heavy transportation non-conditioned roads will be conducted in the surface level following the ring growing pattern. A perimeter road will connect all the rings between them and allow access to every corner of the settlement for any construction machinery needed. The construction of these roads will stand on the underground transportation roads and will be very simply built in the Martian regolith by placing perimeter light buoys.
· Underground transportation: wheeled light transportation conditioned roads will be provided in further stages of the settlement development when an underground perimeter ring corridor for light electrical cars such as the ones used in golf courses. This transportation might not be needed in the very beginning of the settlement but further on will be very useful for community transportation between one ring to another. The construction of these roads will require open air tranches to be able to build the steel framework for the tunneled sections that afterwards will be covered with regolith. Some parts of the ring-road system will let the light in through courtyards and then glazed sections will be built.
When all the underground transportation system will be built, it will connect the whole settlement in a continuous volume. This would become a problem if decompression occurs in any point. In order to avoid it, several floodgates will be built in every ring to divide the system into smaller volumes that can be isolated in case of a loss of pressure.
· Underground paths: pedestrian underground conditioned paths will be built in order to connect all the buildings between them. Access to every building will be provided through pressure doors that will automatically close in there is a pressure loss. All of the buildings will have at least two accesses to ensure emergency egress loop. The construction of this net will require open air tranches in order to build the steel sections with continuous welding that afterwards will be covered with regolith.
3.5.1. General Configuration
The concept design is then driven by two main considerations:
· An actual planning that allows future growth of the settlement.
· The risk of mission failure due to the fact of not reaching the desirable construction technology.
In order to attend to those considerations, two major decisions are taken in the development of the general configuration for the Gen1.5 Settlement:
· A ring strategy is set in order to provide a pattern that will drive the future growth of the settlement by just adding new rings to the actual configuration.
· A set of construction technologies that do not compromise the general development in case any of them is not conducting results as were desired. This is then translated in a set of different building techniques and geometries for each of the functions required.
3.5. Gen 1.5 Settlement
Considering the above mentioned, the document focuses now on the urban and architectural design for a Gen1.5 settlement.
