The new map created from data collected by Chandrayaan-3 is a significant achievement in lunar cartography. This is the first detailed geological map of the moon's south polar region, specifically where India’s Vikram lander made its historic landing. The map provides crucial insights into the moon's origin, evolution, and geological history, enriching our understanding of this celestial body.
The map was developed by a collaborative team of researchers from several prestigious institutions, including the Physical Research Laboratory (PRL) in Ahmedabad, Panjab University in Chandigarh, and the Laboratory for Electro-Optics Systems at the Indian Space Research Organisation (ISRO) in Bengaluru. They utilized data gathered by the Pragyan rover, which was deployed by Vikram.
According to the map, the landscape surrounding the landing site is characterized by an undulating topography of highlands and flat plains. Researchers traced the alignment of secondary craters and identified Schomberger as the primary source of debris in the Chandrayaan-3 landing zone.
Using the geological map, scientists estimated the region's age to be approximately 3.7 billion years. This timeline coincides with the period when the first signs of microbial life emerged on Earth, providing a fascinating parallel between the two celestial bodies.
The Chandrayaan-3 mission was groundbreaking as it was the first to land in a high-latitude polar region. The data collected confirmed the existence of a vast underground ocean of molten rock, or primordial magma, that spans the moon's surface.
Lunar craters serve as valuable indicators for understanding the evolution of impact craters not only on the moon but also on Earth and other planets. They assist scientists in calculating the age of geological features on various celestial bodies, shedding light on the early solar system.
As lunar exploration advances, concerns arise regarding potential issues such as lunar littering, contamination of lunar ice reserves from lander exhaust, and disturbances to the moon's thin atmosphere (exosphere) due to increased human activity.
Earth and the Moon share similar evolutionary paths, evidenced by their geological and chemical characteristics. Their common isotopes and alignment within the solar system suggest that they originated from the same cloud of molten material, highlighting their interconnected histories.
The moon's sterile environment, characterized by its airless and dry conditions, preserves craters for extensive periods, making them exceptional tools for studying the history of impacts within the solar system.
The Vikram lander touched down near the South Pole Aitken Basin, one of the largest and oldest impact craters in the solar system. Researching this basin is pivotal for understanding the early history of both the moon and the solar system.
