In a remarkable stride for lunar exploration, Chandrayaan 3, the latest mission by the Indian Space Research Organisation (ISRO), has unveiled two major findings about the moon’s surface in its week-long venture on the lunar South Pole. The mission, launched just a week ago, has not only provided new insights into the moon’s composition but has also shed light on the intriguing temperature variations experienced on the lunar surface.
Chandrayaan 3’s Pragyan rover, which softly touched down on the moon’s South Pole on August 23, has been diligently conducting a series of groundbreaking scientific experiments. This marks the first instance of any country soft-landing on the moon’s southernmost extremity, a feat that ISRO Chief S Somnath described as a significant milestone. He explained that the South Pole’s unique characteristics, such as reduced sunlight exposure, potentially make it a prime candidate for future human colonization.
A key revelation stemming from the mission is the confirmation of the presence of various elements on the lunar surface, particularly near the South Pole. Aluminium (Al), sulphur (S), calcium (Ca), iron (Fe), chromium (Cr), titanium (Ti), manganese (Mn), silicon (Si), and oxygen (O) have been identified through comprehensive spectral analysis. These findings hold substantial importance as they pave the way for potential future endeavors, such as investigating the presence of water on the moon if hydrogen is detected, a critical resource for any lunar habitation plans.
As Pragyan rover embarked on its exploration of the lunar terrain, it encountered a noteworthy obstacle in the form of a 4-meter diameter crater, situated a mere 3 meters ahead of its trajectory. Swift action was taken as Pragyan was rerouted to navigate around this lunar terrain feature. These craters, a common feature on the South Pole, bear testament to the region’s tumultuous past and complex geological history.
The mission’s data has also provided valuable insights into the temperature dynamics experienced on the moon’s surface. Chandrayaan 3’s measurements unveiled a wide temperature range, spanning from -10 degrees Celsius to approximately 70 degrees Celsius. Intriguingly, the lowest temperature of -10 degrees Celsius was registered at a depth of 80 mm beneath the lunar surface, while temperatures as high as 60 degrees Celsius were recorded at a height of about 20 mm above the ground.
Chandrayaan 3’s rapid progress in unveiling lunar secrets showcases the prowess of ISRO’s scientific endeavors and its contributions to advancing our understanding of the moon’s composition and characteristics. As the mission continues its exploration, the world awaits further revelations that could redefine our perception of Earth’s closest celestial neighbor.
