The latest Mars-related design and architecture, including proposals for NASA's 3D Printed Habitat Challenge and Foster + Partners' concept for robot-built habitat on the red planet. This recyclable polymer composite Â outperformed concrete in NASAâs strength, durability, and crush testing. , To contend with these constraints, architects have worked to understand the right balance between in-situ materials and construction, and ex-situ to Mars.  In this case the atmosphere only partially disintegrated the meteor before it struck the surface.. During the late 1960s, the United States produced the Saturn V rocket, which was capable of launching enough mass into orbit required for a single-launch trip holding a crew of three to the surface of the Moon and back again.  It has a double walled spherical design filled with water to both keep the higher-pressure of Mars habitat in, but help protect against radiation. Students Design Space Habitat Concepts for Mars. ISRU circumvents the hard limits of the rocket equationâwherein every 10 pounds of rocket needs roughly 90 pounds of propellant. Get It From Bacteria!  Some of the challenges for solar power include a reduction in solar intensity because Mars is farther from the sun, dust accumulation, and periodic dust storms, in addition to the usual challenges of solar power such as storing power for the night-time.  One design was planned for an output of 40 kilowatts, and its more independent of the sunlight reaching the surface of Mars which can be affected by dust storms. Polar locations in winter −195 degrees F (−125 degrees C). As such, Mars habitats may have a need for additional gases.  By the time of ISS, space crew-persons had almost 200 medications available, with separate pill cabinets for Russians and Americans. NASA’s 3D-Printed Habitat Challenge that kicked off in 2015 has challenged teams around the U.S. to render, prove the structural integrity, and construct a model of a habitat that could one day shelter humans on the surface of the Moon or even Mars. Students design a sustainable community, considering criteria and constraints in an engineering and design process, learning Earth science concepts along the way. A Mars habitat is a place that humans can live in on Mars. Barchania Alpha was a finalist of Mars City Design Challenges 2016.. In creating a habitat for people, some considerations are maintaining the right air temperature, the right air pressure, and the composition of that atmosphere.  Things like electronics and lights generate heat that rises in the air, even as there are extreme temperature fluctuation outside. One concern on Mars is the effect of the fine Martian dust working its way into the living quarters or devices. And there’s a window every Mars year — every 26 months, at a time called a Mars opposition when Mars is close to the Earth. NASA launched the 3D-printed habitat challenge back in 2015 to find suitable artificial accommodation concepts for the first wave of martian residents. Mars Habitat – Concept Design.  An alternative may be to build above ground, but use thick ice to shield from radiation but with advantage that it lets visible light in. However, the amount of energy required to transfer material to the surface of Mars is an additional task beyond simply getting into orbit.  An advantage of living underground is that it avoids the need to create a radiation shield above ground. , In the 2010s the idea of using in-situ water to build an ice shield for protection from radiation and temperature, etc. This separation makes the interior environment unbeholden to the conservativism required of the outer shell, which retains its simple and effective form.  Iron has also been suggested as a building material for 3D printed Mars habitats.  Plants noted for colonizing the barren landscape in the aftermath of the Mt Saint Helen's eruption included Asteraceae and Epilobium, and especially Lupinus lepidus for its (symbiotic) ability to fix its own nitrogen.  An example of how engineering demands and operational goals can interact, is a reduced-pressure green house area. Architecture on Earth plays a critical role in the way we live. , In 2015 the SHEE project noted the idea of autonomous construction and preparation for Mars habitat versus human construction. , An example of regolith simulant is Martian regolith simulant (further information about Mars analogs List of Mars analogs), One example concept that is or is in support of habitat is a Mars biodome, a structure that could hold life generating needed oxygen and food for humans.  In the 21st century there have been proposed ways of cleaning off solar panels on the surface Mars that are accumulating dust.  The proposed location was Gale crater (of Curiosity rover fame) with a focus on using both in-situ iron and water which would hopefully be available there. SEArch+ won NASA's Centennial Challenge for a 3D-Printed Habitat for their proposal, Mars …  Another infamous space related accident is the Apollo 1 incident, when a pure oxygen atmosphere ignited in the interior of space capsule during tests on the ground, three died.  This would help convert the regolith into soil by creating an organic element. Missions present stresses and challenges that must be addressed spatially, reflecting the strict flow of tasks typical of space missions. Referring to Mars, a similar technique would require a Mars Excursion Module, which combines a crewed descent-ascent vehicle and short stay surface habitat.  Another idea is to use robots to construct the base in advance of human's arrival.. Compared to others, their design looks downright luxurious. Marsha's unique vertically oriented, egg-like shape maintains a small footprint, minimizing mechanical stresses at the base and top which increase with diameter. Significant challenges for Mars habitats are maintaining an artificial environment and shielding from intense solar radiation.  A closer comparison can be made to crewed high-altitude aircraft, which must withstand forces of 1,100 to 1,400 pounds per square foot when at altitude. In 2010 the Space Launch System, or growth variants therefore, is envisioned as having the payload capacity and qualities needed for human Mars missions, utilizing the Orion capsule.  For example, one idea is to use the locally available regolith to shield against radiation exposure, and another idea is to use transparent ice to allow non-harmful light to enter the habitat. The use of living plants or other living biologicals to aid in the air and food supply if desired can have major impact on the design. Another issue with closed system is keeping it free from contamination from emissions from different materials, dust, or smoke. Marsha, AI SpaceFactoryâs Mars habitat design, illustrates that the result can be both visionary and credible with an alien yet familiar beauty. The dust is very fine and accumulates on solar panels, amongst other surfaces. appeared in designs.  Martian exploration and settlement at any meaningful and sustainable scale will depend on the utilization of materials found on Mars.  While not at the level of a typical Earth hospital this would transition medical are beyond basic options typical of very small crew sizes (2–3) where the accepted risk is higher. , To convert the entirety of Mars into a biodome directly, scientists have suggested the cyanobacteria Chroococcidiopsis. A short term stay on the surface of Mars does not require a habitat to have a large volume or complete shielding from radiation. ... offering new ways to s upport future space exploration as well as assessing through scale d prototypes the explored design solutions for the Mars habitat and the emergency astronaut module. Some possible areas of needed technology or expertise: A Mars habitat is often conceived as part of an ensemble of Mars base and infrastructure technologies. , See also Effects of high altitude on humans, One of the challenges for a Mars habitat is for it to maintain suitable temperatures in the right places in a habitat.  In time lichen and moss might be established, and then eventually pine trees. , Mock Mars missions or Mars analog missions typically construct terrestrial habitats on Earth and conduct mock missions, taking steps to solve some of the problems that could be faced for one on Mars. It has been estimated that sixteen feet (5 meters) of Mars regolith stops the same amount of radiation as Earth's atmosphere. Mars Habitat Design Objectives Students Will: • Learn about Mars habitat designs • Discuss various human needs during long-term space travel/dwelling • Design and construct a habitat suitable for living on Mars Suggested Grade Level 3rd – 12th Subject Areas Space Science, Technology, Engineering Design, Life Science Timeline  The effects of Martian surface dust on solar cells was studied in the 1990s by the Materials Adherence Experiment on Mars Pathfinder.. They should bear in mind that the Moon has greater temperature changes and no atmosphere for protection but is closer to Earth. , Examples of acute medical emergency possibilies for Mars missions:, An example of spaceflight related health emergency was the inert gas asphyxiation with nitrogen gas aboard Space Shuttle Columbia in 1981, when it was undergoing preparations for its launch  In that case, a routine purge with nitrogen to decrease risk of fire lead to 5 medical emergencies and 2 deaths. , The second-place winner proposed the printing robots build a shield out of in-situ materials around inflatable modules.  They chose an interior inspired by Fingal's Cave and noted the increased protection from high-energy radiation below ground. The atmosphere is thinner so more meteors make it to the surface, so one concern is if a meteor punctured the surface of the habitat causing a loss of pressure or damaging systems. As a result, the interior is free to be designed in the sense we take for granted on Earth â around human needs. Space Exploration Architecture (SEArch+) develops human-supporting design concepts for space exploration. ", "Mars cleaning tech offers method to sweep dust off Earth's solar panels", "Characterization of the Martian surface deposits by the Mars Pathfinder rover, Sojourner", Future Mars Explorers Could Live in Habitats That Build Themselves, "NASA Offers $2.25 Million For Martian Habitat Design - How Could This Contest Help People On Earth? Students will take the lead on research, design, and building.  Mars habitat design can also involve the study of local conditions, including pressures, temperatures, and local materials, especially water.. This type of habitat is too large and heavy to be sent to Mars, and must be constructed making use of some local resource. MARS X-HOUSE is the first place winner in 100% Virtual Design within NASA’s Phase 3 3D-Printed Habitat Challenge. On Skylab all waste was put in a big tank; on Apollo and the Space Shuttle urine could be vented out into space or pushed away in bags to re-enter Earth's atmosphere.  The Mars habitat would have support the conditions of this food source, possible incorporating elements from greenhouse design or farming.  245 GHz, laser, in-situ rectenna construction, and 5.8 GHz designs have been studied.  A medical risk for a Mars surface mission is how, after several months in zero gravity, they astronauts will handle operations on the surface. Average −80 degrees Fahrenheit (−60 degrees Celsius). The HASSELL design for a Mars Habitat has reached the final 10 of NASA’s 3D Printing Centennial Challenge. , Examples of Mars surface temperatures:. Keep in mind that you don’t need to be an expert on Mars! In collaboration with Techmer PM, we've formulated an innovative mixture of basalt fiber extracted from Martian rock and renewable bioplastic (polylactic acid, or PLA) processed from plants grown on Mars. This is enabled by in-situ resource utilization (ISRU) technologies.  One of the many concerns for crewed Mars missions is what pills to bring and how the astronauts would respond to them in different conditions.  Two examples of medical-care situations that been mentioned in regard to people on Mars is how to deal with a broken leg and an appendicitis.  Alternatively, the habitat may be placed underground, which helps solve some problems but creates new difficulties. , Technology to clean dust off the solar panels was considered for Mars Exploration Rover's development. While it is possible for humans to breathe pure oxygen, a pure oxygen atmosphere was implicated in the Apollo 1 fire. Connecting habitats is useful, as moving between separate structures requires a pressure suit or perhaps a Mars rover.  Some examples include Mars EVA suits, Mars rover, aircraft, landers, storage tanks, communication structures, mining, and Mars-movers (e.g.  On Earth, astronauts must often be carted from the spacecraft and take a long time to recover. , One question for Biodomes is how low the pressure could be lowered to, and the plants still be useful. , One idea for a Mars habitat is to use a Martian cave or lava tube, and an inflatable air-lock was proposed by Caves of Mars Project for making use of such a structure. Marsha, AI SpaceFactory’s Mars habitat design, illustrates that the result can be both visionary and credible with an alien yet familiar beauty. The original intention on using the Barchan Dunes as a radiation protection solution for Mars habitat model came from Kwanpo Cheng's project for the Carnegie Mellon University Architecture Studio, lead by Christina Ciardullo. If it can be created on the spot from existing water then it could spare the weight of hauling earth-produced units, whose weight is mostly water.  Medical risks include exposure to radiation and reduced gravity, and one deadly risk is a Solar Particle Event that can generate a lethal dose over the course of several hours or days if the astronauts do not have enough shielding.  As a result, a Mars habitat may use 40% argon, 40% nitrogen, and 20% oxygen. Due to their low overall atomic weight, plastics are effective shields for ionizing cosmic radiation. Taken to an extreme, the question remains just how a low a pressure could a plant survive in and still be useful.  The first stage is a design only, then in the next stage a construction technology based using discarded spacecraft components is conducted, and finally building an actual habitat for Mars using 3D printing technology. So NASA held a contest for the best 3D-printed habitat that might actually work on Mars.  Mars habitats must contend with surface conditions that include almost no oxygen in the air, extreme cold, low pressure, and high radiation. However, the planet does reduce the radiation significantly especially on the surface, and it is not detected to be radioactive itself. Structures must be resilient and interior layouts must be tuned to mission demands.  As the bacteria reproduces the dead ones would create an organic layer in the regolith potentially paving the way for more advanced life. This combination was called a Mars Excursion Module, and also typically featured other components such as basic rover and science equipment. MARSHA is a first principles rethinking of what a Martian habitat could be â not another low-lying dome or confined, half-buried structure but a bright, multi-level, corridor-free home that stands upright on the surface of Mars. From the spaceships to be used for the 8-month journey to the habitats that people will live in, and from terraforming the landscape to the development of a new society, every detail in this collective endeavour must be designed. The tall, narrow structure reduces the need for a construction machine to continuously rove on the surface, reducing risk and increasing speed and accuracy. The winning habitat, called Marsha, is tall and slim, to reduce the need for construction rovers on unfamiliar terrain, according to AI SpaceFactory.  Two ideas for overcoming this are to use an additional array deployed during a dust storm and to use some nuclear power to provide base-line power that is not affected by the storms. The study noted two plants, duckweed (Lemna minor) and water fern (Azolla filiculoides), as particularly suitable, and they grow on the surface of water. Later missions tended to shift to a dedicated descent/ascent with a separate habitat. The Mars Society launched the Mars Analog Research Station (MARS) Project in order to develop key knowledge needed to prepare for the human exploration of Mars. 8 Printable Martian Habitat Designs That We Want To Live In.  One of the difficulties is enduring the global Mars dust storms, which cause lower temperatures and reduce sunlight reaching the surface. Foster + Partners New York’s design for a modular habitat on Mars has been shortlisted amongst 30 finalists for the 3D Printed Habitat Challenge organised by America Makes and NASA. Together, they shield against the extreme exterior environment. , The Biodome 2 spaceflight and closed-loop biosphere test included a library with the living quarters. Students will design and build a Mars Habitat using junk materials. Another issue is waste management. Alternatively, the habitat may be placed underground, which helps solve some problems but creates new difficulties. , One of the medical supplies that may be needed is intravenous fluid, which is mostly water but contains other things so it can be added directly to the human blood stream. MARS X HOUSE employs an evidence-based design process to introduce the design and constructability of a future habitat for a crew of four to live and work on Mars … Without ISRU the cost of importing materials from Earth renders the project of extraterrestrial futures impossible.  The contenders explored many possibilities for materials, with one suggesting separately refining iron and silica from the Martian dust and using the iron to make a lattice-work filled in with silica panels.  Biosphere 2 tested several people living in closed loop biological system, with several biological areas in support including rainforest, savannah, ocean, desert, marsh, agriculture, and in an area in support of a living space. , At about 150 thousand feet of altitude (28 miles (45 km)) on Earth, the atmospheric pressure starts to be equivalent to the surface of Mars.
