"Water Premium Can Wait for India's Moon-Tied Chandrayaan 2 Mission" | India news



NEW DELHI: India's Chandrayaan 2 mission on its way to the moon could be a pleasant surprise when it lands a rover on the unsnared Moon South Pole, as the latest studies indicate it Much more ice could give water to the region than previously thought.
The Moon's South Pole region hosts some of the most extreme environments in the Solar System: it is unimaginably cold, massively cratered, and has areas that are either bathed in sunlight or in the dark.
That's why NASA plans to send 2024 astronauts there as part of its Artemis program.
On July 22, the Indian Space Research Organization (Isro) Chandrayaan-2 launched its powerful rocket GSLV-MkIII-M1
from the Sriharikota Spaceport in Andhra Pradesh.
Chandrayaan-2 began his historic 48-day journey to the South Pole of the Moon, where he will begin his search for water.
"The South Pole region of the Moon has more shadows than the North Pole region, and there may be a permanent shaded region in the craters called a cold trap," said Sudip Bhattacharyya, associate professor at the Tata Institute of Fundamental Research in Mumbai (TIFR ).
"So it's more likely that ice and some other volatile elements will remain in the water and occur in the Southern Pole," Bhattacharyya, who was not involved in the study, told PTI.
University of California researchers at Los Angeles (USA) describe their study of the similarities between Mercury craters and lunar craters.
In their article published in the journal Nature Geoscience, they report evidence of thick ice deposits in permanently shaded simple craters on the moon.
"We measured the depth-to-diameter ratio of approximately 2,000 simple craters near the north pole of mercury using mercury laser altimeter data, and note that at higher latitudes, these craters become significantly flatter where known The researchers wrote in the paper.
A parallel study of about 12,000 lunar craters using NASA's Lunar Reconnaissance Orbiter (LRO) data reveals a similar morphological trend near the Moon's south pole According to the scientists, this is also due to the presence of thick ice deposits.
"We note that previously discovered surface ice deposits in the southern polar region of the Moon are spatially correlated with shallow craters, suggesting that the surface ice exhumed by diffusion or can be connected to the underground ka nn, "the researchers said.
"The family of lunar craters we identify is a promising destination for future missions and may also help to resolve the apparent discrepancy between the abundance of frozen volatiles on Mercury and the Moon."
"This is important not only for water, but also to study a fossil record of the early solar system and to understand the related history of the Earth-Moon system." Chandrayaan 2 Lander is said to be the first to be in this region landed gently, "Bhattacharya added.
Researchers at NASA's Goddard Space Flight Center in the US found craters to be the most enticing feature of this southernmost region. Some of them never see the light on their floor.
Due to the permanent darkness, LRO has measured the coldest temperatures in the solar system in these craters, which have become known as the perfect environment for storing material such as water for eons, they said.
In an article published in the journal Geophysical Research Letters, NASA scientists said it turns out that despite a temperature that drops to minus 233 degrees Celsius and is likely to keep frost practically forever in the ground, Water has slowly escaped from the top, super-thin layer of the lunar surface.
"Some areas in these polar craters are considered watershed, and that was," said William M. Farrell of NASA's Goddard Space Flight Center.
"But there are solar wind particles and meteoroids that hit the surface, and they can cause reactions that typically occur at warmer surface temperatures, which was not particularly highlighted," Farrell said.
Having first gathered evidence, ISRO plans to continue these experiments with Chandrayaan-1 of water on the surface of the Moon by mapping the expansion and distribution of water.
According to ISRO, a sample of "primeval water" could pave the way for Major's findings regarding the formation of water on the Moon.
Bhattacharya noted that the lander and the rover together have five types of instruments for measuring the surface and atmospheric composition, the physical properties of the surface and the seismic activities that will undoubtedly be the first few key findings.
Scientists say that although it is important to remember that even in shaded craters, water is slowly leaking, it is possible for water to be added. O.
Icy comets that could collide with the solar wind on the moon refill it as part of a global water cycle.
To confirm his team's calculations, Farrell said, a future instrument that can detect water vapor should find one to 10 water molecules per cubic centimeter above the lunar surface that were released by collisions.
For the upcoming science and exploration, the scattering of water particles could be good news, he said.
