Bangalore: Chandrayaan-3’s rover Pragyan, which has India’s national symbol Ashoka Pillar and the ISRO logo on its rear wheel, was unable to leave a ‘clear’ impression of the two on the lunar surface. According to scientists this is a good sign. This gives a new understanding of soil properties in the Moon’s south polar region. The south polar region of the Moon is going to witness many future missions, because of the potential for water here. New information about the soil in the moon’s south polar region could prove crucial for missions that predict the presence of life on the moon.
ISRO Chairman S. Somnath said this in a report of Times of India. Says S Somnath, ‘The blurred impression of the Ashoka pillar and logo gave a new perception. We already know that it (soil) is different, but we need to find out what makes it different. The soil of the moon is not dust, but molten. This means that if something is binding the soil, we need to study what is binding the soil.
The images produced were tested on the Lunar Soil Simulant (LSS) built by the ISRO Satellite Integration and Test Establishment (Isite), where it left a clear impression. The LSS was developed to match lunar soil samples collected by the US Apollo program. This soil sample was taken from the equatorial region of the Moon. Where ISRO’s Chandrayaan-3 landed near the Moon’s South Pole. The soil in different parts of the moon is also different.
Traces of loose soil have been found on the moon
The report quoted Physical Research Laboratory (PRL) director Anil Bhardwaj as saying, ‘We can see very clearly that the rover is causing leaks on the surface of the moon. Photos taken around the landing site and where the rover moved show that the leak caused by the movement of the rover is about a centimeter deep. Lander legs (four legs of Vikram Lander) are sinking into the lunar surface, indicating loose soil. The deeper we go, the denser the soil becomes.
When will Pragyan and Vikram wake up?
ISRO chairman S. about the awakening of Vikram and Pragyan. Somnath said, ‘There has been no contact yet. But we cannot say that now prajna and vikram will not work. We will wait for a full moon day (14 Earth days) and continue trying to establish contact. During this period, sunlight will continuously fall on the south pole of the Moon and the temperature will continue to rise. It will also heat the lander and the intelligence instruments. So both can wake up on the 14th day. We have no other way to contact you other than to try and wait for the full 14 days.
