in the upper 1m of the soil.
Like Earth, the obliquity of Mars undergoes periodic changes which can lead to long-lasting changes in climate. Once again, the effect is more pronounced on Mars because it lacks the stabilizing influence of a large moon. As a result the obliquity can alter by as much as 45°. The effects of these periodic climate changes can be seen in the layered nature of the ice cap at the Martian north pole. Current research suggests that Mars is in a warm interglacial period which has lasted more than 100,000 years.

Because the Mars Global Surveyor was able to observe Mars for 4 Martian years, it was found that Martian weather was similar from year to year. Any differences were directly related to changes in the solar energy that reached Mars. Scientists were even able to accurately predict dust storms that would occur during the landing of Beagle 2. Regional dust storms were discovered to be closely related to where dust was available.

Layered sedimentary deposits are widespread on Mars. These deposits probably consist of both sedimentary rock and poorly indurated or unconsolidated sediments. Thick sedimentary deposits occur in the interior of several canyons in Valles Marineris, within large craters in Arabia and Meridiani Planum (e.g. Henry Crater ), and probably comprise much of the deposits in the northern lowlands (e.g., Vastitas Borealis Formation). The Mars Exploration Rover Opportunity landed in an area containing crossbedded (mainly eolian) sandstones. Fluvial-deltaic deposits are present in Eberswalde Crater and elsewhere, and photogeologic evidence suggests that many craters and low lying intercrater areas in the southern highlands contain Noachian-aged lake sediments.

This implies that there are seasons on Mars, like on Earth. The eccentricity of Mars' orbit is 0.1, ( Earth's 0.02). The large eccentricity causes the insolation on Mars to vary as the planet orbits the Sun. As on Earth, Mars' obliquity dominates the seasons but deu to the large eccentricity, winters in the south are long and cold while those in the North are short and warm.
Observations by NASA's 2001 Mars Odyssey spacecraft show a global view of Mars in intermediate-energy, or epithermal, neutrons. Soil enriched by hydrogen is indicated by the deep blue colors on the map, which show a low intensity of epithermal neutrons. Progressively smaller amounts of hydrogen are shown in the colors light blue, green, yellow and red. The deep blue areas in the polar regions are believed to contain up to 50 percent water ice in the upper one meter (three feet) of the soil. Hydrogen in the far north is hidden at this time beneath a layer of carbon dioxide frost (dry ice). Light blue regions near the equator contain slightly enhanced near-surface hydrogen, which is most likely chemically or physically bound because water ice is not stable near the equator. The view shown here is a map of measurements made during the first three months of mapping using the neutron spectrometer instrument, part of the gamma ray spectrometer instrument suite. The central meridian in this projection is zero degrees longitude. Topographic features are superimposed on the map for geographic reference.

A Comparison of the Atmospheres of Earth and Mars
The mineral olivine occurs all over the planet, but some of the largest concentrations are in Nili Fossae, an area containing Noachian-aged rocks. Another large olivine-rich outcrop is in Ganges Chasma, an eastern side chasm of Valles Marineris (pictured). Olivine weathers rapidly into clay minerals in the presence of liquid water. Therefore, areas with large outcroppings of olivine-bearing rock indicate that liquid water has not been abundant since the rocks formed. Pyroxene minerals are also widespread across the surface. Both low-calcium and high-calciumpyroxenes are present, with the high-calcium varieties associated with younger volcanic shields and the low-calcium forms more common in the old highland terrain. Because enstatite melts at a higher temperature than its high-calcium cousin, some researchers have argued that its presence in the highlands indicates that older magmas on Mars had higher temperatures than younger ones.
Upper atmosphere, or thermosphere: This region has very high temperatures, caused by heating from the Sun. Atmospheric gases start to separate from each other at these altitudes, rather than forming the even mix found in the lower atmospheric layers.
`10km ~10km cummulus clouds
The atmosphere of Mars is a resource of known composition available at any landing site on Mars. It has been proposed that human exploration of Mars could use carbon dioxide (CO2) from Martian atmosphere to make rocket fuel for the return mission. Mission studies that propose using the atmosphere in this way include the Mars Direct proposal of Robert Zubrin and the NASA Design reference mission study. Two major chemical pathways for use of the carbon dioxide are the Sabatier reaction, converting atmospheric carbon dioxide along with additional hydrogen (H2), to produce methane (CH4) and oxygen (O2), and electrolysis, using a zirconia solid oxide electrolyte to split the carbon dioxide into oxygen (O2) and carbon monoxide (CO).
Middle atmosphere: Mars has a jetstream, which flows in this region. ~45km

The scale height of the atmosphere is about 11 kilometres (6.8 mi), somewhat higher than Earth's 7 km. The atmosphere is quite dusty, giving the Martian sky a light brown or orange color when seen from the surface; data from the Mars Exploration Rovers indicate that suspended dust particles within the atmosphere are roughly 1.5 micrometres across.

WINTER CAP (DRY ICE)
DRY ICE SNOWFALL ON M AR S ASA's Mars Reconnaissance Orbiter (MRO) data have recored evidence of CO2 snowfalls on Mars, unveiling the only known example of CO2 snow falling in our solar system.
Mars' south polar residual ice cap is the only place on Mars where frozen CO2 persists on the surface year-round. How the CO2 from Mars' atmosphere gets deposited is still in question. These results shows that snowfall is especially vigorous on top of the residual cap.The finding of snowfall could mean that the type of deposition - snow or frost - is somehow linked to the year-to-year preservation of the residual cap Source: Nasa News Room, released : 11 Sep 2012

CO2 freezes at -125ºC to become what is known as dry ice. The recent discovery established clouds that are composed of CO2 - flakes of Martian air - which are thick enough to result in snowfall accumulation at the surface. The snow falls occurred from clouds around the south pole in winter (NASA's Phoenix Lander mission in 2008 observed falling water-ice snow on northern Mars.) The new analysis based on data from observations in the south pole during southern Mars winter in 2006-07, identifys a tall CO2 cloud about 500 km diameter persisting over the pole and smaller, shorter-lived, lower-altitude CO2 ice clouds at latitudes from 70 to 80 degrees south.

Oranges and redson the map (values greater than weight 4.5 % water-equivalent hydrogen at the surface) point out areas where the amount of deeply buried water ice is greater than what can fit in the pore spaces of the surface rocks.

These dune fields cover an area the size of Texas in a band at the edge of Mars' north polar cap. Most data suggested they were fairly static, but new satellite observations have shown that towering sand dunes are actually dynamic and active.
Polar caps on Mars changes dramatically with the seasons. In winter, the caps become much larger as CO2 freezes on the surface . This happens when the temperature drops to about 150K, and the cap extends down to about latitude 50° by the beginning of spring.
If the ice from the south pole was distributed uniformly over the Martian surface, it would cover the planet 36 feet deep in liquid water. But the flood plains seen on the surface suggest that there was over 10 times as much water originally present on Mars.

SOUTHERN POLAR CAP
Dust devils occur when the sun warms up the air near a flat, dry surface. The warm air then rises quickly through the cooler air and begins spinning while moving ahead. This spinning, moving cell may pick up dust and sand and leave behind a clean surface. Martian dust devils can be up to fifty times as wide and ten times as high as terrestrial dust devils, and large ones may pose a threat to terrestrial technology sent to Mars. Dust devils have been reported to clean dust of the solar panels of two Rovers in Mars, restoring power levels and exapanding work productivity.
During the summer, the caps recede but never completely disappear. The permanent cap at the Martian north pole is formed not of dry ice, but of water ice. The residual north polar cap has been measured to be about 1000 km in diameter with a thickness of about 3 km.

SOUTH POLE The south polar cap is much smaller, ~350 km in size and thicker than the north cap. It is formed of dry ice with an unknown thickness of water ice. Here, the temperature never gets above 150K, so the dry ice survives the summer. The caps are different because of the eccentricity of the Martian orbit which is over five times that of the Earth, and larger than all planets except Mercury and Pluto. This results in the planet being significantly further from the sun during summer at the south pole.

Due to the thin atmosphere on Mars and no magnetic field around it, Mars is highly vulnerable to radiation from space, namely solar radiation and cosmic rays.

This gas flow destabilizes the sand on Mars' sand dunes, causing sand avalanches and creating new alcoves, gullies and sand aprons on Martian dunes. In some places, hundreds of cubic yards of sand have avalanched down the face of the dunes.
Recent discovery of the presence of water ice in the euquatorial belt of Mars has lead to change in directioin of rover missions. Studies of water on Mars can now be carried out in the more tolerable climate in the Equator, where previous studies were made inaccesible in the polar regions by its harsh climate.

The dunes are covered by a seasonal CO2 frost that forms in early autumn and remains until late spring. Grainflow is triggered by when the CO2 frost sublimes seasonally.

The atmosphere of Mars is a resource of known composition available at any landing site on Mars. It has been proposed that human exploration of Mars could use carbon dioxide (CO2) from Martian atmosphere to make rocket fuel for the return mission.Two major chemical pathways for use of CO2 are the Sabatier reaction, converting atmospheric CO2 along with additional hydrogen (H2), to produce methane (CH4) and oxygen (O2), and electrolysis, using a zirconia solid oxide electrolyte to split the carbon dioxide into oxygen (O2) and carbon monoxide (CO).

SUN LIGHTING WIND RADIATION WATER BACTERIA
SALTATION OF SAND From the Latin verb “to jump,” this is the process whereby sand grains move in the wind by individual leaps, and, landing on a hard surface, bounce off again; if a grain lands amongst other grains on the surface of a dune, the impact kicks some of them up into the wind and the crowd of flying grains grows. It is these two contrasting behaviours – bouncing versus splashing – that explain the self-accumulating nature of dunes. Over a hard surface of rocks and pebbles, the trajectories of individual grains are high into the air, and they keep on bouncing. As soon as they hit a soft surface of a dune, they kick off more grains, but the trajectories are lower and
Flight Assembled Architecture, 2011-2012, FRAC Centre Orléans Flight Assembled Architecture is the first architectural installation assembled by flying robots, free from the touch of human hands. The installation is an expression of a rigorous architectural design by Gramazio & Kohler and a visionary robotic system by Raffaello D’Andrea. Flight Assembled Architecture consists of over 1.500 modules which are placed by a multitude of quadrotor helicopters, collaborating according to mathematical algorithms that translate digital design data to the behavior of the flying machines. In this way, the flying vehicles, together, extend themselves as “living” architectural machines and complete the composition from their dynamic formation of movement and building performance. Within the build, an architectural vision of a 600m high “vertical village” for 30’000 inhabitants unfolds as model in 1:100 scale. This newly founded village is located in the rural area of Meuse, taking advantage of an existing TGV connection that brings its inhabitants to Paris in less than one hour. It is from this quest of an “ideal” self-sustaining habitat that the authors pursue

SOLAR SINTERS Case study: markus kayser, 2011 The Solar Sinter - The Potential of Desert Manufacturing In a world increasingly concerned with questions of energy production and raw material shortages, the Solar Sinter project explores the potential of desert manufacturing, where energy and material occur in abundance. In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy
ACOUSTIC LEVITATION - DISLODGING MARTIAN DUST Finding ways of dealing with the fine dust is a high priority because the problems it can cause could drastically affect any long-term exploration. The thin atmosphere on Mars means dust particles are not as rounded as they would be on Earth and can remain quite sharp and abrasive, and they have a high electrostatic charge, which means the fine dust clings to everything and can penetrate space suit air locks, and make solar panels inoperable. The researchers from the Department of Physics and Materials Science Program carried out a feasibility study to develop an acoustic dust removing system for use in space stations or habitations on the Moon or Mars. They found a high-pitched (13.8 kHz, 128 dB) standing wave of sound emitted from a 3 cm aperture tweeter and focused on a reflector 9 cm away was strong enough to dislodge and move extremely fine (<2 µm diameter) dust particles on the reflector surface. The sound waves overcome the van der Waals adhesive force that binds dust particles to the surface, and creates

This was a solar-powered, semi-automated low-tech laser cutter, that used the power of the sun to drive it and directly harnessed its rays through a glass ball lens to ‘laser’ cut 2D components using a cam-guided system. The Sun-Cutter produced components in thin plywood with an aesthetic quality that was a curious hybrid of machine-made and “nature craft” due to the crudeness of its mechanism and cutting beam optics, alongside variations in solar intensity due to weather fluctuations.
for applications away from Earth. The technology is cheap and uses readily found parts, but there is one enormous problem: it will only work when it is sealed inside a space station or other habitation. It will not work where there is no atmosphere (such as the moon) or where the atmosphere is low pressure and thin (such as Mars) because sound is a pressure wave that travels through the air. This limits its usefulness because inside an enclosed space station there would be relatively little dust, and probably other readilyavailable means of removing it without resorting to acoustic levitation.

WHEN Intermediate stage between I &II will be the focus of the project, where few small and tight research base are set up in anticipation of more teams working on Mars. More dwelling structure have to be built to increase habitable space in a short span of time, and limited resource from Earth. An infrastructural set up for the production of local built materials will have to be set up. Large structure need not always require specific ground preparation, a combination of portable installations, robotics assembly and working with natural elements can yield quick results. Base development stages. Stage I: Manned missions to Mars can be launched every 3 years. Slowly more and more small modules will appear on Mars and a settlement of such metal cylinders, linked with airlocks will appear, enlarging the usage surface of the growing Martian base. Various scientific equipment and robots can be sent, including ones enabling production based on local resources. Stage II: These resources will allow construction of habitats for several dozen or more people. Also deployable habitats can be brought from Earth. A transport module 8 m in diameter and height, instead of a return vehicle can contain structures packed in a way portable architecture is packed on Earth. Thus, without using local resources or more complex methods large habitable space can be gained. This is the issue I am trying to solve in this paper. Stage III: In the future large human settlements may appear on the surface of the Red Planet. They will be covered by great domes or placed underground. Terraforming and change of the atmosphere into one suitable for breathing will last for 100 years.

sand as insulation
A particular microorganism, Bacillus Pasteurii, is flushed through the dunescape (an analogy could be made to an oversized 3d printer), which causes a biological reaction that turns the sand into solid sandstone. The initial reactions finish within 24 hours; it would take about a week to saturate the sand enough to make the structure habitable. The bacteria are non-patogenic and die in the process of solidifying the sand. This part of the project relies upon research carried out by professor Jason De Jong's team at the Soil Interactions Laboratory, UC Davis (http://www.sil.ucdavis.edu/people-jason.htm)

If we allow ourselves to dream, we could even fantasise about ways in which the wind could do a lot of this work for us: solidifying parts of the surface to force the grains of sand to align in certain patterns, certain shapes, having the wind blow out our voids, creating a structure that would change and change again over the course of a decade, a century, a millenium.

SAND BAGS The project – a kind of bio-architectural test-landscape – would thus "go from a balloon-like pneumatic structure filled with bacillus pasteurii, which would then be released into the sand and allowed to solidify the same into a permacultural architecture." Different types of construction methods involving pile systems that could probably be used to get the bacteria down into the sand – a procedure that would be analogous to using an oversized 3D printer, solidifying parts of the dune as needed. The piles would be pushed through the dune surface and a first layer of bacteria spread out, solidifying an initial surface within the dune. They would then be pulled up, creating almost any conceivable (structurally sound) surface along their way, with the loose sand acting as a jig before being excavated to create the necessary voids. If we allow ourselves to dream, we could even fantasise about ways in which the wind could do a lot of this work for us: solidifying parts of the surface to force the grains of sand to align in certain patterns, certain shapes, having the wind blow out our voids, creating a structure that would change and change again over the course of a decade, a century, a millenium.

BACTERIA AS GLUE Case study: Dune, Magnus Larsson
A particular microorganism, Bacillus Pasteurii, is flushed through the dunescape (an analogy could be made to an oversized 3d printer), which causes a biological reaction that turns the sand into solid sandstone. The initial reactions finish within 24 hours; it would take about a week to saturate the sand enough to make the structure habitable. The bacteria are non-patogenic and die in the process of solidifying the sand. This part of the project relies upon research carried out by professor Jason De Jong's team at the Soil Interactions Laboratory, UC Davis SI, SILICON +

AGENDA Harnessing dust storms and suspended sand particles to create local building material on Mars, through a combination of low technology (wind movement) and advanced material science, to create a landscape of infrastructural entities.
ORIGAMI ARCHITECTURE = MODULAR SYSTEM + DEPLOYABLE STRUCTURE + PNEUMATIC SKIN
In a intermediate stage of human exploration on Mars, where few small research base have already been set up in anticipation of a larger human colony on Mars. More infrastructure will have to be built to increase habitable space, without adding to the ever increasing pay load. An infrastructural system for the production of local built materials will have to be set up. Large structure need not always require specific ground preparation, a combination of deployable installations, robotics assembly, working with natural elements can yield quick results.
The foundation of the base does not require terrain leveling, instead the base structure strengthen over time as sand and dust composite deposits on it, until it reaches a certain stiffness and stability for human inhabitation.
SAND + DEPOSITION = SHELTER + LANDSCAPE The structures are deployed and are allowed to grow for an appropriate amount of time before it gains sufficient stiffness and insulating factor for human occupany. In this interim period of construct, the structure will serve as temporary storm shelters for rovers and other space exploration vehicles, and also as the begining attempts at introducing human landmarks and artifacts for our navigational instincts.
The proposal is based on systematic growth by algorithm. The goal is to find a sequence that is allows for universal growth in various configurations for a fixed set of modules. Each module serves as unpressurised volumes in which various functions and plug-in vehicular programs can take place . While adapting the technologies of portable architecture to the construction potential of space architecture three concepts were deemed most suitable: metal, mixed and pneumatic structures. Pneumatic architecture allows structure to be taken down easily and reconstructued at another location. The skin can also be prefabricated to suit the adherance property of sand and dust particles in Mars that determines the movement or saltation of sand. S

Sand storms are inextricably tied to the micro climate and temperatures on Mar. While it could be that sand storm occurs because of a rise in temperature (variance), it could also be that the sand in the atmosphere itself becomes an insulating agent that triggers the

M SERIES SHELTER
DEPLOYABLE RAPID ASSEMBLY SHELTERS (MARTIAN) FOO YU YU DOLLY
Single exterior cover DRASH Series Shelters provide emergency response personnel with a variety of rapidly-deployable, rugged, lightweight, man-portable and userfriendly soft-walled shelters. Deployed or taken down by only 2 - 4 personnel within a matter of minutes without the need for special tools or dealing with loose parts, the shelter design is based on the the folding patterns of origami science. DRASH is a free-standing, selfsupporting structure that requires no power or air to erect. Additionally, there are no obstructions such as center poles or locking devices needed to keep the shelter erect. The frame of the Shelter is manufactured from reinforced Mylar速 and Titanite速, a rugged and durable aerospace material, with a flex strength 270% greater than that of aluminum, giving the DRASH Shelter the ability to withstand dust storms, solar radiation and the harsh Martian environment. Kit of Parts(K.O.P): Each shelter comes with a retainer/housing case, repair kit, Velcro belt, wind lines and a steel pin stake set.

THE VEHICLE (SEV) On planetary surfaces, astronauts will need surface mobility to explore multiple sites across the lunar and Martian surfaces. The SEV surface concept has the small, pressurized cabin mounted on a wheeled chassis that would enable a mobile form of exploration. These two components could be delivered to the planetary surface together, or as separate elements. The SEV can provide the astronauts’ main mode of transportation, and – unlike the unpressurized Apollo lunar rover – also allow them to go on long excursions without the restrictions imposed by spacesuits. The pressurized cabin has a suitport that allows the crew to get into their spacesuits and out of the vehicle faster than before, enabling multiple, short spacewalks as an alternative to one long spacewalk.

DESIGN CONSIDERATIONS FOR INFLATED / PRESSURISED SPACES
AIR LOCK / ACCESS
Airlocks are required at entrances to prevent loss of internal air-pressure. Eg. revolving door, airlock portals, zippers, Velcro. When using a double wall construction; one doesn't need a proper door.
The skin of pneumatic system determines much spatial quality of the construct. In responding to environmental demands, and by integrating material technologies, one can look for qualities like scales in translucency or elasticity. Materials can be highfrequency sealed, glued or just stitched. Other qualities are; non static, lightweight, strong, resistant to tearing, self-repairing. Considerations are made to use microfibers, nonwovens, woven vecram (used in the space industry), metallic foils, plastic films.

Mars Pathfinder 
The Mars Pathfinder airbag system was designed to protect the lander regardless of its orientation upon impact with the surface of the planet. The system also was designed to handle lateral movement as well as vertical descent. The huge, multi-lobed air bags, which will envelope and protect the Mars Pathfinder spacecraft before it impacts the surface of Mars. The air bags are composed of four large bags with six smaller, interconnected spheres within each bag. The bags measure 5 m tall and about 5 m in diameter. As Pathfinder is descending to the Martian surface on a parachute, an onboard altimeter inside the lander will monitor its distance from the ground. The computer will inflate these large air bags about 100 meters above the surface of Mars.
