For a long time, the moon has been considered to lack liquid water as a symbol of the earth, but the distribution of lunar water is more extensive than previously known.
Although space mining is still a far away concept, it is a reality for the mining industry. For many years, space mining was mostly science fiction, but now many governments have implemented plans and legislation to allow them to participate in this competition. The confirmation of the presence of water on the moon is good news for future space mining.
On Monday, at a press conference held by the National Aeronautics and Space Administration (NASA), researchers showed two results published in the journal Nature-Astronomy, which confirmed that there is relatively abundant water on the lunar surface, one is the lunar surface minerals The other kind of molecular water wrapped in crystals is solid ice with larger reserves and possibly hidden in the permanent shadow of the moon.
This means that water not only exists at the poles of the moon, but also on the surface of the moon where light can reach and where sunlight cannot.
They believe that this discovery is very important for future astronauts and robots to perform space missions because they can provide drinking water or fuel sources.
Molecular water on the surface of the moon
In the first study, researchers observed the moon at NASA's Stratospheric Infrared Astronomical Observatory (SOFIA). The wavelengths used can reveal the characteristics of water molecules or H2O in natural glass or between crystal grains.
Although research 11 years ago indicated that there may be more widely distributed water on the moon, this is the first time that water molecules have been detected on the moon. Previous observations did not clarify whether it is water or its similar hydroxyl group. This time, a new detection method that can confirm that it is water is used.
Studies believe that the only way for water to exist on the surface of the moon under the sun's rays is to be embedded in the crystal grains, so that it can be protected from destruction in extreme cold and dangerous environments.
The chief scientist of the research team, Casey Honniball from NASA’s Goddard Space Flight Center, said, “Many people think that what I have detected is water ice, which is wrong. This is just water molecules because They are too dispersed, cannot interact with each other, cannot form water ice or even liquid water."
More widely distributed ice
At the same time, another team led by Paul Hayne, a professor of planetary science at Colorado State University at Boulder, proposed that a permanent shadow area covering approximately 15,000 square miles (40,000 square kilometers) of the moon may be hidden. Water in the form of ice.
Using data obtained by NASA's Lunar Reconnaissance Orbiter, the team focused on the so-called cold traps on the moon, which are areas on the moon's surface in a state of permanent darkness, with temperatures even as low as -260°F (Celsius). -163°C). According to research, some of these places may not receive sunlight for decades.
Hein said, "If you stand at the poles of the moon, you can see all the shadows. Many small shadows may hide ice. Our research shows that the distribution of water in the moon’s polar regions is more extensive and easier than originally thought. Arrival, mining and analysis."
PUDA mining packing machine:
PUDA automatic quantitative packaging machine, particle packaging machine, powder quantitative packaging machine and double spiral packaging machine are mainly composed of automatic weighing device, conveying device, sewing device and computer controller. Show the set weight, cumulative number of packages, working status and other procedures. The device adopts fast, medium and slow feeding and special feeding auger structure, advanced digital frequency conversion control technology, advanced sampling processing and anti-interference technology, in order to realize automatic error compensation and correction to ensure higher weighing accuracy.
The characteristic of this product is through the processing of computer software, to solve the same kind of products can not solve the problem, namely pneumatic card opening material substitute landing, powder spill phenomenon, showing its higher technology content accuracy.
