Space produce technical water

Astronauts living and working km above our planet might prefer not to think about it, but the water they drink is recycled from their colleague's sweat and exhaled breath — collected as condensation on the Space Station's walls. Water is precious on Earth but even more so in space where all drinkable water must be transported from home or recycled. As water is a dense and heavy substance it takes a lot of energy to propel it into space — there is only so much a rocket can carry so the less water we send, the more scientific equipment can be sent in its place. This is one of the reasons why there is no shower on the International Space Station — astronauts wash themselves only with wet-wipes for six months! Astronauts in space often list fresh fruit and a shower as the things they miss most from Earth. As we explore further from our home planet providing water and food to astronauts will become more and more challenging so just like on Earth reduce, reuse, and recycle is the mantra for off-world explorers and their space agencies.

Water in space

VIDEO ON THE TOPIC: Astronauts Drink Urine and Other Waste Water - Video

In space exploration , in situ resource utilization ISRU is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects the Moon, Mars, asteroids, etc. ISRU could provide materials for life support , propellants , construction materials , and energy to a spacecraft payloads or space exploration crews.

It is now very common for spacecraft and robotic planetary surface mission to harness the solar radiation found in situ in the form of solar panels. The use of ISRU for material production has not yet been implemented in a space mission, though several field tests in the late s demonstrated various lunar ISRU techniques in a relevant environment.

ISRU has long been considered as a possible avenue for reducing the mass and cost of space exploration architectures, in that it may be a way to drastically reduce the amount of payload that must be launched from Earth in order to explore a given planetary body.

According to NASA , "in-situ resource utilisation will enable the affordable establishment of extraterrestrial exploration and operations by minimizing the materials carried from Earth. In the context of ISRU water is most often sought directly as fuel or as feedstock for fuel production. Applications include its use in life support either directly by drinking, for growing food , producing oxygen , or numerous other industrial processes.

All of which require a ready supply of water in the environment and the equipment to extract it. Such extraterrestrial water has been discovered in a variety of forms throughout the solar system, and a number of potential water extraction technologies have been investigated.

For water that is chemically bound to regolith , solid ice, or some manner of permafrost, sufficient heating can recover the water. However this is not as easy as it appears because ice and permafrost can often be harder than plain rock, necessitating laborious mining operations. Where there is some level of atmosphere, such as on Mars, water can be extracted directly from the air using a simple process such as WAVAR. Another possible source of water is deep aquifers kept warm by Mars's latent geological heat, which can be tapped to provide both water and geothermal power.

Rocket propellant production has been proposed from the Moon's surface by processing water ice detected at the poles. The likely difficulties include working at extremely low temperatures and extraction from the regolith.

Most schemes electrolyse the water to produce hydrogen and oxygen and cryogenically store them as liquids. This requires large amounts of equipment and power to achieve.

Alternatively, it may be possible to heat water in a nuclear or solar thermal rocket , [4] which may be able to deliver a large mass from the Moon to low Earth orbit LEO in spite of the much lower specific impulse , for a given amount of equipment. The monopropellant hydrogen peroxide H 2 O 2 can be made from water on Mars and the Moon. Aluminum as well as other metals has been proposed for use as rocket propellant made using lunar resources, [7] and proposals include reacting the aluminum with water.

For Mars, methane propellant can be manufactured via the Sabatier process. SpaceX has suggested building a propellant plant on Mars that would use this process to produce methane CH 4 and liquid oxygen O 2 from sub-surface water ice and atmospheric CO 2.

It has long been suggested that solar cells could be produced from the materials present in lunar soil. Silicon, aluminium, and glass, three of the primary materials required for solar cell production, are found in high concentrations in lunar soil and can be utilised to produce solar cells. Solar arrays produced on the lunar surface can be used to support lunar surface operations as well as satellites off the lunar surface. Solar arrays produced on the lunar surface may prove more cost effective than solar arrays produced and shipped from Earth, but this trade depends heavily on the location of the particular application in question.

Another potential application of lunar-derived solar arrays is providing power to Earth. In its original form, known as the solar power satellite , the proposal was intended as an alternate power source for Earth. Solar cells would be shipped to Earth orbit and assembled, the power being transmitted to Earth via microwave beams. The colonisation of planets or moons will require obtaining local building materials, such as regolith.

For example, studies employing artificial Mars soil mixed with epoxy resin and tetraethoxysilane , produce high enough values of strength, resistance, and flexibility parameters. Asteroid mining could also involve extraction of metals for construction material in space, which may be more cost-effective than bringing such material up out of Earth 's deep gravity well, or that of any other large body like the Moon or Mars.

Metallic asteroids contain huge amounts of siderophilic metals , including precious metals. Many of the proposed techniques utilise the well-characterised atmosphere of Mars as feedstock.

Since this can be easily simulated on Earth, these proposals are relatively simple to implement, though it is by no means certain that NASA or the ESA will favour this approach over a more conventional direct mission. Oxygen is liberated from the water by electrolysis , and the hydrogen recycled back into the Sabatier reaction.

The usefulness of this reaction is that—as of [update] , when the availability of water on Mars was less scientifically demonstrated—only the hydrogen which is light was thought to need to be brought from Earth. As of [update] , SpaceX is developing the technology for a Mars propellant plant that will use a variation on what is described in the previous paragraph. Rather than transporting hydrogen from Earth to use in making the methane and oxygen, they intend to mine the requisite water from subsurface water ice that is now known to be abundant across much of the Martian surface, produce and then store the post-Sabatier reactants, and then use it as propellant for return flights of their Starship no earlier than The net result of this reaction is the production of oxygen, to be used as the oxidizer component of rocket fuel.

Another reaction proposed for the production of oxygen and fuel [20] is the electrolysis of the atmospheric carbon dioxide,. In this cycle, water reacts with wustite FeO to form magnetite Fe 3 O 4 and hydrogen. The summarised reactions in this two-step splitting process are as follows:. This process is repeated cyclically. The above process results in a substantial reduction in the thermal input of energy if compared with the most direct, one-step process for splitting molecules.

However, the process needs wustite FeO to start the cycle, but on Mars there is no wustite or at least not in significant amounts. Nevertheless, wustite can be easily obtained by reduction of hematite Fe 2 O 3 which is an abundant material on Mars, being specially conspicuous the strong hematite deposits located at Terra Meridiani.

The proposed Mars Surveyor lander was to demonstrate manufacture of oxygen from the atmosphere of Mars , [27] and test solar cell technologies and methods of mitigating the effect of Martian dust on the power systems, but the project was cancelled. It has been suggested that buildings on Mars could be made from basalt as it has good insulating properties.

An underground structure of this type would be able to protect life forms against radiation exposure. All of the resources required to make plastics exist on Mars. Traces of free oxygen, carbon monoxide, water and methane are all known to exist. These basic reactions provide the building blocks for more complex reaction series which are able to make plastics.

Ethylene is used to make plastics such as polyethylene and polypropylene and can be made from carbon monoxide and hydrogen, [35]. The Moon possesses abundant raw materials that are potentially relevant to a hierarchy of future applications, beginning with the use of lunar materials to facilitate human activities on the Moon itself and progressing to the use of lunar resources to underpin a future industrial capability within the Earth-Moon system.

The lunar highland material anorthite can be used as aluminium ore. Smelters can produce pure aluminium, calcium metal, oxygen and silica glass from anorthite. Raw anorthite is also good for making fiberglass and other glass and ceramic products. Over twenty different methods have been proposed for oxygen extraction from the lunar regolith. This process has recently been made much more practical by the discovery of significant amounts of hydrogen -containing regolith near the Moon's poles by the Clementine spacecraft.

Lunar materials may also be used as a general construction material, [42] through processing techniques such as sintering , hot-pressing, liquification , and the cast basalt method. Cast basalt is used on Earth for construction of, for example, pipes where a high resistance to abrasion is required. Other proposals [47] are based on Phobos and Deimos. These moons are in reasonably high orbits above Mars, have very low escape velocities, and unlike Mars have return delta-v 's from their surfaces to LEO which are less than the return from the Moon.

Ceres is further out than Mars, with a higher delta-v, but launch windows and travel times are better, and the surface gravity is just 0. Researchers have speculated that the interior configuration of Ceres includes a water-ice-rich mantle over a rocky core.

Proposals have been made for "mining" for rocket propulsion , using what is called a Propulsive Fluid Accumulator.

Atmospheric gases like oxygen and argon could be extracted from the atmosphere of planets like the Earth, Mars, and the outer Gas Giants by Propulsive Fluid Accumulator satellites in low orbit. The team's report, along with those of 14 other capability roadmap teams, were published 22 May The report focuses on lunar and martian environments.

It offers a detailed timeline [50] : and capability roadmap to [50] : — but it assumes lunar landers in and The lunar Resource Prospector rover was designed to scout for resources on a polar region of the Moon, and it was proposed to be launched in The first formal solicitation is expected sometime in From Wikipedia, the free encyclopedia.

Explorers and travelers throughout history have had to develop methods for preserving food and carrying enough food for their journeys. This problem was especially difficult during the time when people made long sea voyages on sailing ships. Great explorers like Columbus, Magellan and Cook carried dried foods and foods preserved in salt and brine. More recently, refrigeration and canning have provided solutions to the problem of food preservation. However, space travel required that new methods be devised for keeping foods edible. Foods taken into space must be light-weight, compact, tasty and nutritious.

Recycling water in space

When it comes to mining space for water, the best target may not be the moon: Entrepreneurs' richest options are likely to be asteroids that are larger and closer to Earth. A recent study suggested that roughly 1, water-rich, or hydrated, asteroids near our planet are easier to reach than the lunar surface is. While most of these space rocks are only a few feet in size, more than 25 of them should be large enough to each provide significant water. Altogether, the water locked in these asteroids should be enough to fill somewhere around , Olympics-size swimming pools — significantly more than the amount of water locked up at the lunar poles, the new research suggested.

The Spinoff publication has documented more than 2, technologies over time. In , notable science fiction author Robert A. Heinlein helped bring awareness to the spinoffs when he was asked to appear before Congress after recovering from one of the earliest known vascular bypass operations to correct a blocked artery; in his testimony, reprinted in his book Expanded Universe , he claimed that four NASA spinoff technologies made the surgery possible, and it was a few from a long list of NASA spinoff technologies from space development. Well-known products that NASA claims as spinoffs include memory foam originally named temper foam , freeze-dried food , firefighting equipment, emergency " space blankets ", DustBusters , cochlear implants , LZR Racer swimsuits, and CMOS image sensors. As of , NASA has published over 2, other spinoffs in the fields of computer technology, environment and agriculture, health and medicine, public safety, transportation, recreation, and industrial productivity. Spinoff is a NASA publication featuring technology made available to the public. Since , NASA has featured an average of 50 technologies each year in the annual publication, and Spinoff maintains a searchable database of these technologies. Because of interest in the reports, NASA decided to create the annual publications in color. Spinoff was first published in , [5] and since then, NASA has distributed free copies to universities, the media, inventors and the general public.

How NASA Hopes to Mine Water on the Moon

NASA has long planned to mine water on the moon to supply human colonies and future space exploration. Now the discovery of small amounts of water across much of the lunar surface has shifted that vision into fast-forward, with the U. A hydrogen reduction plant and lunar rover prospectors have already passed field tests on Hawaii's volcanic soil, and more radical microwave technology has shown that it may be used to extract underground water ice. Water mined by these methods could not only keep astronauts supplied with a drink, but may also provide oxygen and fuel for lunar missions. He pointed to a cost-analysis study conducted by the NASA Ames Research Center in California that suggested such extraction technologies could pay for themselves within a year. Still, Sanders cautioned that big unknowns must be conquered before NASA engineers can go prospecting for lunar water. They need to know how much water the moon holds, where it is, and how deep they have to excavate. One probe, NASA? NASA scientists have quietly worked on water mining technologies for years in small laboratories. But a full-blown program did not emerge until the latest vision for living off the land and using lunar resources emerged in

Endlessly recycling waste such as urine and sweat, the system uses a chain of filters, bacteria in bioreactors and chemical reactions to produce clean water and food. The goal is to become completely self-sufficient so astronauts could travel through deep space forever producing the three basic elements of life: water, oxygen and food.

But as Marric Stephens explains, a new follow-on mission is also helping with plans for a space-based gravitational-wave detector. Imagine the sea on a still day, calmer than you have ever seen it, with no wind to stir its surface, and no currents or tides to disturb its depths. Now imagine that the sea has risen to cover the whole face of the planet, submerging the continents and even the highest mountain peaks.

During the last space shuttle flight, astronauts will test a new method for recycling 'used' water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future space explorers. Water - it's essential for life.
