New research based on India’s Chandrayaan -3 mission data suggests that the poles may have ice in more locations below the lunar surface than before the poles. Published in studyCommunication Earth and EnvironmentHighlights how local temperature variations can affect the formation of ice, over time, it can shed light on its origin and movement.
The lead author of the Physical Research Laboratory in Ahmedabad, Dr. Durga Prasad Karanam said that examining these ice particles can reveal insight into the early geological history of the moon. The study analyzed the temperature reading taken at a depth of up to 10 cm below the lunar surface recorded by the ‘Chast’ investigation in Chandrayaan -3 Vikram Lander.
Chandrayan -3, launched by the Indian Space Research Organization (ISRO) from Bengaluru, successfully achieved a soft landing on the south pole of the moon on 23 August 2023. The landing site, later named ‘Shiva Shakti Point’, sits at about 69 degrees south latitudes.
Rift in temperature and construction of ice
The research team found that the surface temperature at the landing site vary dramatically, reaching about 82 ° C with day peaks and reaches -170 ° C at night. Just one meter from the landing point, on the surface of a flatter, the peak temperature was low, about 60 ° C.
In particular, the difference in temperature was attributed to the location of the lander on a slight inclination, which increased the solar radiation risk. This inspired researchers to develop a model, in which it was assessed how the slope angle affects surface temperature at high lunar latitude. Their findings indicate that at an angle of 14 degrees or more, with the sun faced away from the sun, the surface may be cool enough to allow the ice to accumulate.
Implications for future lunar missions
The findings of the study include important implications for future lunar exploration, which includes NASA’s planned Artemis Mission, which aims to give land to astronauts near the south pole of the moon. Researchers suggest that the ice can be more comprehensive and accessible than already eclipse, potentially serving as an important resource for future human exploration and residence.
However, Dr. Karanam clarified that liquid water may not be present on the moon due to extremely low atmospheric pressure, which means that the ice will be directly into vapor instead of melting in liquid form. They emphasized the need for further measurements and new techniques to extract ice for long -term lunar stability and use new techniques.
The authors of the study concluded that the sacred conclusions indicate fine changes in lunar resolith temperature and high latitude areas as promising places for water-armed scouting and resource prevention. He said that such sites can be scientifically valuable, while the moon may withstand less technical challenges than areas close to poles.
