Thanks to the SOFIA telescope it was confirmed the presence of water on the Moon. This was announced by NASA during a press conference held in these minutes.
According to what emerged, the water on the Moon would have come through the meteorites that impacted the surface.
Thanks to the presence of permanently shaded areas, the water molecules were able to withstand the difficult conditions of the satellite. The estimated amount is 100 ppm - 412 ppm (parts per million) in the first meter of the surface but the total amount is not yet clear.
A bottle of water dispersed in a cubic meter of regolith. The affected area is the Clavius crater but in the future new observations will be made to improve the accuracy of the data and expand knowledge on the phenomenon.
The results of the analyzes show that in more southern latitudes water is present in abundance (about 100-400 parts per million), probably sequestered in glassy or rocky matrices. "This tells us that the Moon could be less arid than expected, but it is not yet possible to establish how much water there is and how much is usable: this discovery will certainly help us to better plan future missions," said experts.
The Sofia telescope, mounted on board a Boeing 747, has solved the mystery by analyzing the spectrum of the Moon at a wavelength of 6 micrometers at which water can no longer be confused with anything else.
There is water on the moon!
Paul Hertz, director of the astrophysics division at NASA, said: "We had indications that the water we know, may be present on the sunny side of the moon. We now know it is there. This discovery challenges our understanding of the lunar surface and raises intriguing questions.
on resources relevant to deep space exploration." The results of the analyzes show that in more southern latitudes water is present in abundance probably sequestered in glassy or rocky matrices. The SOFIA telescope has dimensions of 2.7 meters with an effective diameter of 2.5 meters.
This allows us to study the Solar System and all those situations where there are dust that block visible light (but not infrared). Furthermore, the possibility of moving around the world also allows you to change your "point of view" on the phenomenon to be observed.
The discovery announced today and which has the Moon at its center, was completed thanks to the SOFIA telescope. It is a very special telescope considering that it is housed inside a Boeing 747SP, allowing it to fly at a maximum of almost 14 km.
This is important because at those heights the natural infrared radiation filter of the earth's atmosphere is exceeded (99%). It is thus possible to acquire information that alternatively only space telescopes can capture, all without the complexity of a launch and related maintenance and control problems.
