In our solar system, there are planets crowded with moons; Saturn, the sixth planet from the Sun and the second-largest planet in our solar system, has a maximum of 142 moons. Right before the planet Saturn, the biggest planet in our solar system, has 92 moons. The only planet where life exists, based on current observations, is Earth; it has only one natural satellite, also known as the Moon. This solitary lunar companion is now at the heart of a global space race, revealing surprising changes that could shape humanity’s cosmic ambitions.
India marked a historic milestone with its Chandrayaan-1 mission, launched on October 22, 2008, by the Indian Space Research Organisation (ISRO). This mission uncovered water molecules across the lunar south pole, igniting global interest in lunar exploration. On August 23, 2023, India’s Chandrayaan-3 achieved the world’s first soft landing near the south pole at 69°S latitude, dubbed Shiv Shakti Point. This triumph made India the fourth nation to soft-land on the Moon, joining the Soviet Union, the United States, and China, and solidified its role in unlocking the Moon’s secrets.
Recent research reveals the Moon is shrinking as its core cools, contracting by about 150 feet in circumference over millions of years. This process creates thrust faults, wrinkling the lunar crust and triggering moonquakes, some reaching magnitude 5, especially near the south pole. Chandrayaan-3’s seismometer detected these tremors, highlighting risks for future missions. Such seismic activity could destabilise landing sites and challenge plans for permanent lunar bases in this resource-rich region.
The lunar south pole has emerged as a prime target due to its permanently shadowed craters, which may hold over 600 million tons of water ice, according to data from Chandrayaan-1 and NASA’s Lunar Reconnaissance Orbiter. This ice is vital for sustaining lunar habitats, providing water, oxygen, and fuel. Chandrayaan-3’s Vikram lander and Pragyan rover conducted key experiments, like the Chandra’s Surface Thermophysical Experiment (ChaSTE), showing temperature swings that suggest accessible ice deposits. These findings guide NASA’s Artemis III mission, set for 2026, and China’s Chang’e 7, also planned for 2026, both aiming to tap into this lunar treasure.
In 2025, India unveiled plans for Chandrayaan-4, a 2028 mission to return 6.6 pounds of south pole samples, including water-ice-rich material, using advanced drilling and orbital docking. Meanwhile, ISRO’s collaboration with Japan’s JAXA on Chandrayaan-5 (LUPEX), targeting 2028–2029, will deploy a robust rover to probe Shackleton Crater’s ice deposits. These missions reflect a global push to harness lunar resources, reducing Earth dependency and enabling sustainable exploration.
The Moon’s shrinking surface and moonquakes pose challenges but also fuel innovation in lunar exploration. As India, NASA, China, and Japan race to secure the South Pole’s resources, data from Chandrayaan-3 and future missions will shape safer landings and long-term habitats. The Moon is no longer just a distant dream—it’s a gateway to Mars and beyond.
