Whether you’re planning on moving to the moon or you’re simply fascinated by the idea of it, you might be interested in a house building service on the moon. There are some exciting ideas for building structures on the moon, including extracting oxygen from the moon’s atmosphere and mining water from the moon’s poles. This article offers some information on these ideas and more.
Texan construction firm ICON recently received a contract from NASA for a 3D printing for house building service on the moon. The company has already delivered over two dozen 3-D printed homes in the United States, and is now working on disaster relief housing and market-rate real estate.
The company’s main goal is to help reduce waste and deliver better homes. In addition, it is working to bring the housing market into the 21st century by delivering homes that are energy efficient, and beautiful.
ICON’s Vulcan II printer can print homes in as little as 24 hours, using a proprietary concrete mix. It can build up to 500 square feet in one day. ICON has recently built an entire community of 3-D printed homes in Mexico.
NASA’s Small Business Innovation Research contract includes funding to develop new technologies for Project Olympus, which is aimed at developing robotic construction technologies for structures on the Moon. ICON has enlisted the help of space architecture firm SEArch+, and Danish architectural firm BIG.
Extraction of water from ice at the moon’s poles
During the second half of the twentieth century, evidence of free water ice on the Moon was found in craters near the poles. This discovery sparked a great deal of excitement and led to plans for a return to the Moon in the future.
Researchers found that the crater Cabeus, near the south pole, contains a hydroxyl signature, which indicates water ice on the Moon. This has led to speculation about “cold traps” that may exist in the craters.
These areas may freeze water vapor and capture it permanently. These areas may extend up to forty thousand kilometers on the Moon.
The Clementine spacecraft discovered water ice on the Moon in 1994. In a subsequent study, scientists determined that the moon had large quantities of water in the form of glass. These ice particles were likely formed when small meteors collided with hydroxyls on the Moon’s surface.
Another study has found that a large percentage of the Moon’s surface is covered in low concentrations of hydroxyls. These compounds are likely to be the precursors to water on the Moon.
Modular and inflatable structures
During the 1990’s, NASA was experimenting with human missions beyond low Earth orbit. Among other things, they were considering inflatable structures as a way to get around the limitations of cargo space.
This concept has a long history, going back to Werner von Braun’s ‘wheel’ station, which was made up of inflatable sections.
Inflatable space modules are another way to achieve the scalability and efficiency of the lunar outpost. These inflatable structures are capable of providing more habitable space per unit of mass than conventional metal structures.
Inflatable structures can also be rigidized into specialized modular units. For example, they can be used to support a concrete wall. They can also be used for science instrument antennas. They can also be assembled into large reflectors.
Inflatable houses are also in development. This type of housing would be particularly useful in places where housing needs to be constructed quickly. It could also be used for disaster shelters.
Extracting oxygen from the moon
Having an oxygen extraction plant on the moon would be an incredible benefit to deep space exploration missions. This would allow astronauts to breathe on the moon and would help to make a permanent lunar base. It would also eliminate the huge cost of sending materials from Earth.
Oxygen is found in regolith, a layer of fine gray soil on the moon. The regolith contains 40 to 45 percent oxygen by weight. Oxygen is also bound up in minerals and oxides.
Scientists at the University of Cambridge have developed a technique for oxygen extraction from lunar regolith. The technique uses electrolysis to break the bonds between the minerals and oxygen. The team is trying to increase the purity of the oxygen released by the process.
The oxygen produced is then stored and converted to liquid form. This process has been demonstrated using lunar soil and volcanic glass. Oxygen release can be as high as 96% in these experiments.
