NASA’s laboratory simulation ensures 60 -year estimate, the source of the sun that make water on the moon.
According to theory, when the flow of loaded cells called solar air reaches the lunar surface, Stimulates a chemical reaction that can produce water molecules, The agency was reported on Tuesday Europa Press.
This invention wrote in an article published in JGR planets, It has implications for astronauts at South Lunar Polo at the Artemis Da NASA program.
Most of the moon’s water, a key source for exploration, It is permanently frozen in areas in the shade of poles.
“The most interesting thing is that with the lunar soil and the Sun Building Black, it always releases hydrogen, it is possible to create water,” researcher Li Hsia Yo said at NASA’s Goddard Space Flying Center in Maryland.
Solar air flows from the sun constantly. It is mainly accompanied by protons, which are the nuclei of hydrogen atoms that have lost electrons.
When traveling more than a million kilometers per hour, the solar air baths the entire solar system. The evidence was recorded on earth when the sky brightened with the famous Borial or Southern Aroras.
Space probe dimensions They have already suggested that solar air is mainly due to the formation of water or its parts on the lunar surface.
An important track, Yeo is confirmed by the experience of the group: The spectral signature of the moon is related to water changes all day.
In some areas, it is more severe in the cold morning and weakens when the surface is overheating, as water and hydrogen molecules move or miss into space.
When the surface cools overnight again, the signal reaches its peak. This daily cycle represents active source — probably solar air — It fills a small amount of water on the moon every day.
To test it, Ye and his colleague, Jason McLine, a scientist in NASA Goddard, They built a device that was prepared to examine the lunar samples of Apollo.
For the first time, this device has all the parts of the experience: the air -beam beam device, the air that mimics the lunar environment -the free room and the atoms detector.
A. The inventionAllowed researchers to avoid removing the sample from the chamberAs happened in other experiences, and expose to water contamination in the air.
In 1972, NASA Apollo 17 astronauts, using two different models of dust collected on the moon, were first shot by yo and their colleagues to remove any water between Hermetic Storage in Houston.
Then they used a small cell accelerator to bomb the imitation solar dust for several days — based on the overdose of the cells used, the moon was equal to 80,000 years.
Used a detector known as Cania to measure the amount of light reflected by dust molecules, It has shown how the chemical composition of the models has changed over time.
Finally, The group noticed the light signal decrease in the infrared area of the electromagnetic spectrum (about 3 microns) that definitely reflected from their detector during the infrared area, where the water usually absorbs energy, Leave the signal that reveals.
