Proto City, the first city on Mars, stands for one of the greatest human achievements. It all started with the first robotic mission and construction of the first unit, the Proto Cell, which housed only eight astronauts. As time went on and technology progressed at fast pace, the cell grew and expanded until it reached the size of a city. At this time, high-tech materials make it possible to use a transparent shell to allow light in.
The wave-like shape has its origin in the first regolith shell created in 2034. Slightly rounded, almost dome-like, it grew in numbers, and through the variation in size and shape a rhythm was created: waves running and spilling over the craters‘ rim. The barriers between separate units disappeared, and a large sealed shell emerged that can
The positioning provides constant sunlight during the day, and the wavy surface redirects wind. A central location of the nuclear powerplants ensures consistent distance of 16 km between the reactors and the growing city. The Launching-Landing Site is located at a safe distance of 5 km. A large number of craters in the area raise the possibility of expansion.
Mastersection through Time and ProtoCity Evolution including Population size, Sun and Wind study and given conditions
The first and most important step is to find a location that can help overcome our challenges: materials for construction, water to sustain humans and plants, and good soil to grow food on.
The site is located in the Northern Hemisphere which indicates milder climate and higher minimum solar incidence than the southern hemisphere. Thorium, Silicon, Iron and Potassium are found in medium to high quantities. Thorium is used for the production of nuclear energy, Silicon is used in building materials such as glass, cement, aerogel, and Iron as a building material with high versatility.
High Thermal Inertia, low Dust Index and low Elevation indicate that the soil can retain heat for longer periods. The flat, smooth, and hard ground is desirable for landing and construction, and the accumulation of dust is low. Higher gravity and atmospheric pressure act as a thermal shield and protection against radiation and micrometeoroids. Water is located at a depth of > 0.8 m. The Map from the University and Research at Wageningen shows that the selected site has excellent soil for plant cultivation.
The most important characteristic of the first unit is the outer green belt. It acts as an exercise track, a source of food, noise barrier and a place to relax. It divides quiet private quarters from the noisier common and working areas. The central glazed domed part hosts the socializing
areas and the radio and communication platform as well as a stargazing net hammock. In the initial expansion mode, the separate homes would be connected by linking of green belts through similar green corridors.

The ProtoCity is the first city on Mars, and as such it will become the blueprint for any future cities on the planet. By designing in such a complex environment we face certain issues. The three most important issues are: Radiation, Atmosphere and Quality of Life. To solve the problem of radiation we devised a Smart Shell System. Each panel of the shell is a cell. These smart cells are layered, and each layer has a certain function. They would not only provide protection from the harmful radiation, but also create a pressurized environment, giving people and plants the necessary light to survive.
To ensure daily fresh supply of oxygen we would, to some extent, rely on systems like MOXIE, but our main supply would come from plants and bacteria imported from Earth. So, it is important to ensure biodiversity inside the colony. It starts with laboratory testing in the first unit, on a search for the right combination of soil and seed. As the plants grow, some are used as food and others are used as fertilizer.
Open space represents the freedom to move and socialize, the right to private space, possibility of families, expression of purpose through work and contribution to society. It starts with the green belt that connects different functions and grows on to become a large open space with many possibilities.
Final objective: open space, biodiversity and quality of life expressed through freedom of movement and open possibilities

Our main idea in bringing human life to Mars is the underground usage of daylight in lavatubes. While facing many challenges when building on Mars, it is one of the safest methods to ensure long term habitability on the red planet.
The lighthouse concept aims directly at those challenges by protecting and leading human life through rays – just like on Earth. The concept focuses on a combination of three key elements: Due to radiation it is underground, the center mirror structure lights up the lavatube underground and, all the materials are built in-situ.
The dome connects the surface with the underground. It’s a very vivid social place – a city square in an urban understanding. Due to its glass panels and the dome shape it is able to let in a lot of light. During radiation storms, this area is evacuated. The second part of the city – the column – has essential life supporting functions. Firstly, the mirrored panels on its structure are able to redirect light to the underground city. Secondly, it contains two vertical infrastructures.
The location of choice is the Tharsis region (0° 0‘N, 100° 0’W). Because of its many volcanos and lavatube sunlights which can already be seen from satellites, it‘s most likely that there are more lavatubes underground. Furthermore, volcanic areas are prone to contain ice underground. The region Tharsis has the highest possibility of finding water in caves underground. This can help ensure the first human life on Mars and will also be interesting for research purposes. Lavatube roofs will be 10-90 meters thick, which is enough to protect the population from the surface radiation, galactic cosmic radiation, meteorite bombardment and extreme temperatures.
It is important to say that lavatubes are not thoroughly researched, because the procedure of scanning the underground is quite complicated. While current research by ESA focuses on scanning lavatubes, our concept also includes scouting and research on site.
city completely self-sustainable
To maximize daylight usage in the underground lavatube, we conducted daylight simulations. While trying to find the most efficient shape, the hyperbolic tube seemed to be the most appealing. In order to reflect the sunlight, we decided to use mirror panels as the surface material. The strong aesthetics of the hyperbolic shape influenced our design for the first prototypes.
While speaking of this project, it‘s important to understand that this project is chronologically divided into two parts. The first part is the scouting phase, where a prefabricated first habitat (picture, phase 0) is brought to Mars by a rocket. In this phase the main goal is to find an optimal lavatube for further research, all carried out by robots. The first habitat is seen as a safe shelter, with a focus on planning the extension.
In phase 1, two prototypes are going to be built close to the first habitat (pictures, phase 1). While testing the manufacturing technology and material fabrication on Mars, other tests on food production, power generation and creating/maintain the inside atmosphere/pressure will also be conducted.
The main part of phase 3 is the construction of the dome and mirror column (picture, phase 3). All previously tested materials are going to be used and will finally make the underground usage of the tube possible.
Phase 4 and 5 consist of the underground expansion and pressurization of the tube. Since this process consumes a lot of power, it is important to build extra photovoltaic farms around the dome. phase
OHH GOSH, I - REALLY - CAN’T WAIT FOR THE SIX NEWCOMERS! BUT SURE, FIRST THE PROTOTYPE NEEDS TO BE BUILD.
WOW! THIS PROTOTYPE IS SO BEAUTIFUL.

Earth`s population is growing at a rapid pace, to the point where it becomes concerning that the carrying capacity has been overcome. We are overusing nonrenewable resources such as minerals, fossil fuels, and water. The growing population is causing an incerease in greenhouse gas emissions, which are affecting the atmosphere negatively. Because of these problems, it has become important to look into other planets that could potentially sustain life , one these potential planets its Mars
Our primary goal for budiling the first habitat on Mars is to use In-Situ rescources, which would provide protection, reduce building costs and would be helpful to build a sustainable habitat. The first housing units are going to be built using contour- crafting technology, which is 3d printing using sulfur concrete from extracted martian regolith. Printing will be halfautonomous with humans who will assist in building and maintainance of robots.

The region is located in the planet’s Northern Hemisphere, and has an ample stash of water ice making it an ideal location for any potential human mission to Mars. A new paper published in Geophysical Research Letters details a treasure maps of sorts, pointing to places where researchers believe water ice lurks as little as an inch (2.5 centimeters) below the surface. Researchers are trying to narrow down the best places for astronauts to land and this discovery puts Arcadia Planitia near the top of the list. Data also shows that because this is a temperate region, basked in plenty of sunlight, it wouldn’t be difficult to uncover the watery bounty.

The habitat will have thick, curved, sulphur concrete-printed walls, designed to take advantage of the high compressive strength of concrete and to shield the inhabitants from radiation, while withstanding the high interior pressure of an Earth-like environment.
In order to offer the feeling of being out in the open, indirect lighting is used as main factor even though the lighting on Mars is less than that of Earth`s. Functions are seperated between the floors based on the time spent of them so the radiation times are minimised.
Living on Mars in housing units is good for a short-term stay, but for a longer-term stay we need Earth-like features that could help our body and mental health. Bio-Dome will offer protection against outside factors, will provide solar energy and the needed open-space area for free movement and green landscapes.

The future city Apoikia will provide an extensive lifestyle by creating an Earthlike atmosphere. Because who would want to spend decades, or even their whole life on Mars when there are no birds or bees and you have to expect the same temperature everyday?
Self-sufficient Ecosystem:
One big step from the first habitat to the future city is the creation of an ecosystem, which already provides a variety of plants and animals in the first few phases. The inhabitants will profit from fresh food, air, water, crafting materials like wood and bamboo, which can be used for floors and furniture and the feeling of being in nature.
The dome is used as a shield against radiation and creates the atmosphere. As a static system, the dome only conducts pressure forces, which leads to using less material and wider spans. The form provides a maximum of space with a minimum of surface. The air pressure inside the dome also means more stiffness for the construction.
In-Situ-Resources:
To reduce the expenses of transportation the main focus is on using resources from Mars as building materials. Especially in the first phase it is helpful to have a short production chain and easy, robot friendly building manufacturing using as few layers as possible.
concept self sufficient ecosystem
To provide the necessary Sulfur for the Martian concrete we chose our location based on the amount of sulfur in the top layer of the Martian surface to reduce energy for mining and transportation. The yellow area shows a sulfur proportion of over 3%. Our settlement will start near the Herschel Crater (14.7S, 129.7E).
The Core provides the main infrastructure and distributes resources and goods to the entire city. It connects the city vertically with elevators and horizontally with a railway system to the outsourced factories and spaceport. The diameter of the dome will be about 1600 m to provide enough space for the residents.
It provides the Martians with everything they need; like homes (privacy), society, culture (art, music, theatre), restaurants, entertaining (cinema, club), hospital, sport facilities and education facilities. Because of the optimal dimensions, travelling inside the city will done by foot and bicycle.
It provides the Martians with a big functioning ecosystem similar to the one on Earth; with free space for outside activities like swimming and climbing. There will be parks, a forest, a lake, a beach and a zoo. Birds, insects, changing weather and temperature will also play a vital role.
The first rocket arrives with self-sufficient unpressurized digging-, transportation- and building -robots; inflatables, deployables, hut doors, nuclear fusion reactors, solar panels, batteries, life support systems like MOXIE (Mars Oxygen InSitu Utilization Experiment), ECLLS (Environmental Control and Life Support System) and HVAC (Heating, Ventilation and Air Conditioning Systems), as well as chosen plants and eggs to create a self-sustaining ecosystem.
The robots start mining resources which are used for building the first 3 huts. A few different layers are used to make an easy robot-friendly building manufacturing possible. Martian concrete is used as the first in-situ-resource.
The 3 built huts are connected by using deployables. The second rocket arrives with 6 future inhabitants, they start installing necessary equipment in their huts. 3 more huts are built by the robots to extend the habitat.
The first habitat is completed. A new in-situ-productionchain has been launched to fabricate Polyethylen, which is used as an additional protection layer against cosmic radiation and solar flares. It is also used as reinforcement for the Martian concrete to be able to construct larger buildings.
More humans arrive and the structure of the habitats is growing. Also, silicates are mined and used as a basic product for glass to gain view and natural light inside the buildings.
Larger structures are built. Trees are planted inside to be able to use wood as a new construction material. Also more complex materials like steel and fiber are fabricated to build wide spanned constructions like the future dome.
The grid and membrane of the dome are beginning to take shape to create an atmosphere for the future city. Also higher buildings are much easier to construct inside the dome.
Martian concrete will be used as the main building material for the huts. 12 to 25% sulfur will be mixed with Martian soil and heated up to 140°C. As it hardens when it cools off, the robot can work continuously. The concrete will act as the structure, insulation and protection against radiation; an all in one material to simplify and shorten the manufacturing process. Because of the usage of insitu-resources the huts can be built bigger and provide more space for the habitants.
Step
Step
Step 7: Several layers of concrete are sprayed to achieve the needed thickness of about 1 meter.
Step
Step 8: Gas is let out to reuse the inflatable for the next hut.
Step 9: The finished shell almost exclusively transfers pressure forces. The doorframe will be used as an entrance and to connect infrastructure like pipes. A layer of polyethylene will be added for more protection.
The first 3 huts will be built before the astronauts arrive to serve as a minimum habitat. While the robots will continue constructing the following 3 huts, which provide space for exploring, manufacturing and repairing, the humans install their equipment and coordinate the work. The doorframes of the huts will be connected using a short deployable.
