[MISSION STATEMENT AND SYMBOL]

BIOSPHERE 03 - “REALISING THE IMPOSSIBLE DREAM” Biosphere 03 is pioneering next steps in space exploration and leading the world throughout our journey to Mars

Mars is a rich destination for scientific discovery, robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to earth, helping us learn more about our own planets historical backdrop and future. We believe Mars had conditions suitable for life in its past and now at Biosphere 03 we will be the future.

People will unite and the world will be as one, as we venture towards the seemingly frightening unknown with open eyes and clear minds. Our continued research and investigations will seek to uncover evidence of life, answering one of the fundamental questions of the cosmos:

LIVING ON OTHER PLANETS WHERE WE STAND ON MARS

‘which planet could we live on?’

If you were to live in the northern hemisphere, you’d enjoy about seven months of spring, six months of summer, a little more than five months of fall and only about four months of winter. (A year on Mars is about 1.88 Earth years, and a day lasts a little

more than 24 hours.)

The idea of living on Mars has been a staple of science fiction since the 19th century, when American astronomer Percival Lowell speculated that the channels on the Red Planet were really ancient canals built by intelligent extraterrestrials. But if this sci-fi dream were to ever become reality, what would it be like to actually live on Mars?

In 1965, NASA’s Mariner 4 spacecraft completed the first Martian flyby, and six years later, the Soviet Union’s Mars 3 lander became the first spacecraft to land softly on Mars. Since then, there have been numerous successful missions to the Red Planet, including the deployment of four Mars rovers — the now-defunct Sojourner and Spirit, and the still-active Opportunity and Curiosity — and NASA’s Mars Odyssey spacecraft, which produced a map of the entire planet.

NASA is now planning for a manned mission to Mars, which is planned for the 2030s.

It’s unknown where astronauts will land on Mars for that mission, but for a future Martian space colony, “you’d probably want a permanent base somewhere in the low northern latitudes,” Ashwin Vasavada, a deputy project scientist for NASA’s Mars Science Laboratory has said.

Like Earth, Mars has seasons due to the planet’s tilt upon its axis, but it also has a secondary seasonal effect because of its highly elliptical orbit.

TEMPERATURE AND AIR PRESSURE

GRAVITY AND TIME

Mars’s atmosphere is about 100 times thinner than Earth’s. Without a “thermal blanket,” Mars can’t retain any heat energy. On average, the temperature on Mars is about minus 60 degrees C. In winter, the poles temperatures can get down to minus 125 degrees C. A summer day on Mars may get up to 20 degrees C near the equator, but at night the temperature can plummet to about minus 73 C. Frost forms on the rocks at night, but as dawn approaches and

Scientists have calculated Mars’ gravity based on Newton’s Theory of Universal Gravitation, which states that the gravitational force exerted by an object is proportional to its mass. Since Mars has less mass than Earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.

LOCATION

PRIMARY SITE: GALE CRATER

[BIOSPHERE 03]

The Crater has been chosen as the location for the colony. Currently the site remains the most detailed Mars mission conducted by NASA with extensive orbital data coverage. Gale Crater is a fascinating place to explore because of the mountain of layered materials in the middle. On Earth, this mound would be a mountain 5 kilometres high!

The layers tell a story about what Mars was like in the past, perhaps spanning much of the history of the red planet. Studies from orbit have revealed that the layers have different minerals depending on their height. Near the bottom of the mound are clay minerals. Above the clay-bearing layers are layers with sulphur and oxygenbearing minerals. Flowing water appears to have carved channels in both the mound and the crater wall. To get to the mound, Biosphere’s spaceships would land in a flatter part of the crater and carefully work its way upward, layer by layer. Along the way, robots would investigate how the layers formed and the environments in which they formed.

SPACEX

ELON MUSK

[NET WORTH $15 BILLION]

SpaceX founder Elon Musk has outlined his highly ambitious vision for manned missions to Mars, which he said could begin as soon as 2022. “What I really want to try to achieve here is to make Mars seem possible – like it’s something we can achieve in our lifetimes,”

Elon Musk is a South African entrepreneur known for founding Tesla Motors and SpaceX, which launched a landmark commercial spacecraft in 2012. He has a networth of over $15Billion. He said there were “two fundamental paths” facing humanity today. “One is that we stay on Earth forever and then there will be an inevitable extinction event,” he said. “The alternative is to become a space faring civilization, and a multiplanetary species.”

In order to achieve this goal, Musk outlined a multi-stage launch and transport system, including a reusable booster. The booster, and the “interplanetary module” on top of it, would be nearly as long as two Boeing 747 aircraft. It could initially carry up to 100 passengers, he said.

Missions to Mars would ideally be launched every 26 months when the planet is aligned with Earth. The 2020 planned lander will be critical for future possible manned missions as it will test technology required to land heavy equipment on the Martian surface—a task that, given Mars’unfamiliar terrain and thin atmosphere, could be difficult to execute. Heavy payloads entering Mars won’t have the planet’s atmosphere to cushion their landing and so there is the risk of very abrupt and hard landings.

MARS ONE

BAS LANSDORP

Mars One aims to establish a permanent human settlement on Mars. Several unmanned missions will be completed, establishing a habitable settlement before carefully selected and trained crews will depart to Mars.

Funding and implementing this plan will not be easy, it will be hard. The Mars One team, with its advisers and with established aerospace companies, will evaluate and mitigate risks and identify and overcome difficulties step by step. Mars One is a global initiative whose goal is to make this everyone’s mission to Mars, including yours. If we all work together, we can do this. We’re going to Mars.

The private space-flight project is led by Dutch entrepreneur Bas Lansdorp, who announced the Mars One project in May 2012. Mars One’s original concept included launching a robotic lander and orbiter as early as 2020 to be followed by a human crew of four in 2024 and one in 2026.

Bas lansdorp is a Dutch entrepreneur best known as the co-founder and CEO of Mars One. Mars One’s mission design is currently in the early mission concept phase, or as called in space development terms: Phase A. The top level requirements for the mission have been identified and discussed with established aerospace companies. Possible solutions were proposed and discussed after which a baseline mission concept was defined and rough cost figures were discussed.

3.0 Chapter 3.0 - Understanding Mars It was important for me to research and explore the various characteristics of the planet. Analysing the possibility of construction materials and sustainable energy.

EXPLORING MARS FIVE KEY PROPERTIES

Before designing I wanted to establish a thorough understanding and appreciation for my site, which is effect a planet. By understanding the possibilities and subsequent challenges presented on the planet, I would be able to design accordingly.

1. CONSTRUCTION The best way to build on Mars will be using materials that can be found on the planet. This is because building materials would vastly increase the payload any rocket would need to carry and the cost of getting it to Mars. In-situ recourse utilization is the application of using materials already on the planet.

2. ENERGY Sustainable energy in the form of wind, waste, solar, hydro and geothermal

3. WATER Scientists examined part of Mars’Utopia Planitia region, in the mid-northern latitudes. Analyses of data from more than 600 overhead passes with the on-board radar instrument reveal a deposit more extensive in area than the state of New Mexico.

4. FOOD What crops and food can be grown and the nutrients available in the Martian soil already

5. FROZEN ICE One technique of water mining on Mars could actually be to use microwaves. Cooking some of the regolith.

CHALLENGES OF WIND ENERGY

CHALLENGES OF SOLAR POWER

The atmosphere on Mars is so thin that even a strong wind wouldn’t make that much of a difference.

Mars has below 1% of the pressure on Earth. That means it has less than 1% of the force of wind on Earth with the same speed. Wind happens when there is a pressure gradient between two areas of an atmosphere. Pressure gradients are caused by temperature and humidity gradients.

Individual dust particles on Mars are very small and slightly electrostatic, so they stick to the surfaces they contact. This dust is an especially big problem for solar panels. Even dust devils of only a few feet across - which are much smaller than traditional storms - can move enough dust to cover the equipment and decrease the amount of sunlight hitting the panels. Less sunlight means less energy created.

Analyses of data from more than 600 overhead passes with the on-board radar instrument reveal a deposit more extensive in area than the state

Evidence that Mars once supported liquid water has been mounting for years, and exploratory missions have found that water ice still exists on the planet’s poles and just beneath its dusty surface. Accessing that water could require digging it up and baking it in an oven, or beaming microwaves at the soil and extracting the water vapour. By extracting water we can then further break it down to extract oxygen and hydrogen.

DRY ICE

HEAT ENGINES ON MARS

[SUSTAINABLE ARCHITECTURE]

Martian dry ice already exists close to its “sublimation point”– the temperature at which it turns directly from solid to gas. It therefore only takes a relatively small nudge for dry ice to change states. The challenge is to harness the energy released by this change to power a heat engine – or even a whole colony.

Carbon dioxide plays a similar role on Mars to water on Earth. It is a widely available resource which undergoes cyclic phase changes under the natural Martian temperature variations. The gullies observed on Mars were a topic of debate, as scientists searched for evidence of the water that once created them. But recent studies are overwhelmingly in favour of carbon dioxide.

Power stations on Mars could exploit all this frozen CO2 to harvest the energy from the sublimation phase change as dry-ice blocks evaporate, or to channel the chemical energy extracted from other carbon-based sources, such as methane gas. By placing water droplets and blocks of dry ice on top of hot, turbine-like surfaces, the Leidenfrost effect could be used to create rotational motion. The turbines channel the released vapour, whose flow in turn drives the levitating surface above to rotate. As the turbines rotate there kinetic energy can be transferred and used to generate electrical energy.

It could be possible that future power stations on Mars can exploit such a resource to harvest energy as dryice blocks evaporate, or to channel the chemical energy extracted from other carbon-based sources, such as methane gas. Our future on other planets depends on our ability to adapt our knowledge to the constraints imposed by strange worlds, and to devise creative ways to exploit natural resources that do not naturally occur here on Earth.

A machine could be developed that utilises both e dry ice on Mars and the frozen ice underground. Rather than melting all of it some of it could be used to drive turbines to generate energy for the entire city or colony that exists.

4.0 Chapter 4.0 - Design phase 01 Biosphere Design phase 1 includes the development of the Biosphere on Mars utilising a Biodome.

MARTIAN ARTIFICIAL BIOPSHERE ECOLOGICAL ARCHITECTURAL SYSTEMS

[THE BIODOME]

The objective of the Biosphere 03 project is to colonise Mars and begin a new civilisation. The previous research has highlighted the conditions, problems, challenges and possible solutions to this mission, but critically these are all small independent systems. They require an overall holistic system that will unite them all. That will happen with the creation of a new Biosphere on Mars.

In order to do this, the architectural response to Biosphere 03 is the design and manufacture of an artificial biosphere on Mars, taking the form of a‘Biodome’. A biodome is a form of controlled, self-sufficient eco-system that closely replicates the natural outdoor environment. It is the scientific based form of a greenhouse.

The objective of the Biodome will be to create a place where life can be born and thrive in an otherwise hostile environment. It will be a place where food and water can be grown, generated and reproduced. It will also be conditioned to produce oxygen and other important gases. It will develop as a centre for research and further investigations into the planet. And critically it will help to nurture and raise mental health and well-being of residents in Biosphere 03. It will respond to ideas of rethinking, reusing, recycling and reinventing the way in which we live. Ultimately it will be the solution envisioned for people to live sealed in a world replica of the Earth environment. Acting as a closed loop system, humans, wildlife will operate in perfect balance to sustain one another and allow life to evolve.

THE BIOSPHERE The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rain forests and high mountaintops. Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these spheres.

Although the biosphere measures about 20 kilometres (12 miles) from top to bottom, almost all life exists between about 500 meters (1,640 feet) below the ocean’s surface to about 6 kilometres (3.75 miles) above sea level.

BIOSPHERE 2 CASE STUDY

[HISTORICAL BACKGROUND]

Two missions, between 1991 and 1994, sealed Biosphere inside the glass enclosure to measure survivability.

Behind this highly public exercise was useful research that helped further ecological understanding. Several first-person accounts have been published by former crew members that provide different perspectives on the experiment.

In 1994, Decisions Investments Corporation assumed control of the property and Columbia University managed it from 1996-2003 and reconfigured the structure for a different mode of scientific research, including a study on the effects of carbon dioxide on plants. Columbia also built classrooms and housing for college students of earth systems science.

The property was sold June 4, 2007, to CDO Ranching and its development partners who then leased the property to UA from 2007-2011. The enclosure now serves as a tool to support research already underway

by UA scientists. Biosphere 3 will take understanding and research from the way Biosphere 2 operated.

Developing on from the flaws of Biosphere 02, Biosphere 03 will finally be able to create a liveable habitat on Mars, generating an airlock oxygen society.

CONSTRUCTION: The above-ground physical structure of Biosphere 2 was made of steel tubing and high-performance glass and steel frames. The frame and glazing materials were designed and made to specification. The window seals and structures had to be designed to be almost perfectly airtight, such that the air exchange would be extremely slow, to avoid damage to the experimental results.

During the day, the heat from the sun caused the air inside to expand and during the night it cooled and contracted. To avoid having to deal with the huge forces that maintaining a constant volume would create, the structure had large diaphragms kept in domes. Since opening a window was not an option, the structure also required huge air conditioners to control the temperature and avoid killing the plants within. For every unit of solar energy that entered the structure, the air conditioners would expend approximately three times as much energy to cool the habitat back down.[citation needed]

SUSTAINING LIFE THROUGH NATURE NATURAL BALANCE OF OXYGEN

[INSIDE THE BIODOME]

One of the key aspects of Biosphere 3 is the closed loop oxygen system. An environment where humans can completely depend on plants and organic growth to sustain the correct levels of oxygen. The equations on the right use average quantities and accurate propositions in order to calculate various figures.

The first part of the equation outlines the average amount of oxygen required by an individual - in this case an adult - to live for a day. Then by adopting the equation for photosynthesis, and the average of CO 2 consumed by a tree daily, we can make a guestimate as to the total number of trees that would be required for one human to survive. The final part examines how many plants that might equate and the possible space required.

GENERATING OXYGEN FROM PLANTS Trees release oxygen when they use energy from sunlight to make glucose from carbon dioxide and water.

Like all plants, trees also use oxygen when they split glucose back down to release energy to power their metabolisms. Averaged over a 24-hour period, they produce more oxygen than they use up; otherwise there would be no net gain in growth.

It takes six molecules of CO2 to produce one molecule of glucose by photosynthesis, and six molecules of oxygen are released as a by-product. A glucose molecule contains six carbon atoms, so thatâ&#x20AC;&#x2122;s a net gain of one molecule of oxygen for every atom of carbon added to the tree. A mature sycamore tree might be around 12m tall and weigh two tonnes, including the roots and leaves. If it grows by five per cent each year, it will produce around 100kg of wood, of which 38kg will be carbon. Allowing for the relative molecular weights of oxygen and carbon, this equates to 100kg of oxygen per tree per year.

CONCLUSIONS Conclusions from the equations suggest that for one person to survive 500m 2 worth of plant space would be required. Therefore, for a colony of 100 people that would require 50,000m 2 and 1000 people would require 500,000m 2. The choice of plants is also of paramount importance. Algae and Sugar cane, pictured on the left are examples of plants that represent high CO 2 absorption and Oxygen production.

MARTIAN ARTIFICIAL BIOPSHERE ECOLOGICAL ARCHITECTURAL SYSTEMS

[THE BIODOME]

Designing on Mars from an architectural position means dealing with challenging and unkown site and context conditions. One of the most interesting factors for me is the change in gravity and how that could inform design.

It was also important to me that the architecture develop in a way that.

In this light I began investigating how architecture could sit naturally within the landscape of Mars, and this led me to investigate Frei Otto’s form finding experiments that are based on the studies of sand self-distribution behaviour under the force of gravity.

“Any granular material falling from a fixed point forms a cone on the surface below and a funnel within the granulate mass, with the same angle of inclination, the ‘natural’ angle of repose, 35 degree.” Frei Otto, 1975

The fascination for me is how the angle of repose might vary with the varying degree of gravity on Mars.

Investigations into the angle of repose under gravity suggest that as gravity decreases the angle of repose increases. The angle of repose on Mars could increase by as much as 4-5 degrees and the angle on incedent decrease by up to 10 degrees. I have, therefore, used these pieces of information to inform the architecture of the colony.

Second they become the location of columns that will act as structural support to the arches. Finally they provide the location of the mound dwellings.

By extracting the lines of the voronii pattern, these are projected down onto the ground.

The rivers should flow with clean water and help to reduce heat generated by the colony

An additional element is the introduction of skywalks and bridges. Connecting the living mounds to the communial mounds are a network of bridges. These counter the voronii pattern of the water, creating both an additional means of intercommunication of residents and to encorage movement.

MARTIAN ARTIFICIAL BIOPSHERE ECOLOGICAL ARCHITECTURAL SYSTEMS

[THE BIODOME]

At the final crit one for the fundamental aspects of the design that was brought into question was the inclusion and application of the tower element. I had designed the tower originally with multiple purposes based off research principles. Predominantly, it would act as a solar tower, with a large solar disk at the top that would draw in the sun light. I designed it in this way to attempt to remove the challenges of dust storms that can occur for up to 6 months continuously and reach heights of up to 800m. The nature of dust on Mars means that it would stick to everything, thus rendering any solar panels normally as useless. However, further investigations suggested that the dust and sand can actually completely engulf the entire atmosphere of the planet.

FINAL PRESENATION FEEDBACK [ADVANCING THE DESIGN]

At the final presentation my city was broken down into two main parts. The central biodome and the living colony around it. The fundamental issue with what I had designed related to air pressure. On Mars the atmosphere is so thin that air contained simply wants to expand. I was therefore unloading potentially huge amounts of pressure of the walls of the dome. Furthermore, reducing rather than increasing the amount of contact directly with air pressure of the surface on Mars would be better.

Therefore I started developing the design further, pulling more of the design undergrounds

BIOSPHERE 03

COLONISING MARS [WEDNESDAY, AUG 23, 2024, WEEK 21]

Biosphere 03 is a project that aims to colonise the planet Mars through the construction of an underground inhabitatble environment. Based on evidence gathered from mars exploration programs and sataliete data, the introduction of a new, reconfigured biosphere will exist on the planet to sustain human life. The architectural design is one that responds to the planets natural environmental conditions and synthesises natural organic processes.

DESIGN DEVELOPMENT MAIN DESIGN MOVE

[54KM BELOW GROUND]

The city has been redesigned as a complete whole rather than a circumference as before. The main design move comes in the form of building deep underground. It is scientifically researched that at a depth of 54KM below the surface of Mars, you could experience earth like conditions. The gravity would essentially equal 0 and become what we know on earth. I began to question this and suggest that part of the city be built at this depth. Currently we have no proven method of recreating gravity and this would in some part solve that issue.

CITY OF TWO HALFâ&#x20AC;&#x2122;S 9.81G VS 3.15G I am proposing that the city be broken into two half. The first is the living part of the colony that will remain near the surface. The second is the biodome and working portion that will sit 54km below ground. The idea of Biosphere 03 now is one of human conditioning. Living on other planets will inevitably require and subsequently alter the way that humans behave and evolve. In response to that, Biosphere 03 will develop the human condition and anatomy. Half of the day will be spent in conditions of reduced gravity. This is proven to affect bone and muscle development. The second part of the day involves working below ground at earth like conditions. Here the gravity is normal and the body can recover in its natural state. The theory is that gradually humans will evolve to live in conditions of reduced gravity.

DESIGN DEVELOPMENT SAND CASTING

[INSIDE THE BIODOME]

The colony that the residents inhabit has been designed of some key principles, extending from my investigations into the way sand falls and creates the voronoi forms.

MOUNDS 39 DEGREES Each mound is designed based on a principle of 39 degrees - the scientifically believed angle of repose on Mars.

NETWORK OF RIVERS. From the voronoi pattern that produces the mounds, the lines in between for a network of rivers. This intern creates little islands, for each of the house mounds to occupy. Each family of residents has their own plot of land.

SECONDARY NETWORK. As a way of inducing both movement - in environment where staying active is key because of reduced gravity - and social interaction, travelling around the city is done via sky walks. Providing views out over the city, each mound has a structural concrete concrete column that acts as an elevator as well. You move upwards, then sideways, and then back down to destination. Vertical movement plays as important a role as horizontal, creating an architecturally irony perhaps against the issue of gravity.

SKY LIGHTS The holes formed by the voronoi pattern offer a variety of important purposes. They enable light to penetrate deep into the colony. They also provide the location of each mound and its column. These columns provide secondary support to the carved out caves by the robots.

VEGETATION As a knowledge and understanding would improve on the planet, it would become essential to introduce rich vegetation to the landscape. improving social and human happiness
