Rahul SomvanshiIndia’s Chandrayaan-3 rover has etched its mark on the Moon’s south pole, unveiling groundbreaking discoveries for potential lunar habitats. The Pragyan rover, equipped with the Laser-Induced Breakdown Spectroscope (LIBS), detected sulfur traces and other minerals on the lunar surface. This revelation was announced by the Indian Space Research Organization (ISRO) on X, the platform previously known as Twitter.
Pragyan’s onboard instruments, including the alpha particle X-ray spectrometer, are designed to decipher the Moon’s chemical composition. By firing laser pulses, the rover transforms lunar rock or soil into plasma, analyzing the emitted light to identify elements. Each element, when in its plasma state, emits a unique light wavelength, enabling precise identification. Alongside sulfur, the rover identified aluminum, calcium, chromium, iron, manganese, oxygen, titanium, and silicon on the Moon.
The discovery of sulfur was particularly astonishing, hinting at its potential association with water ice at the lunar south pole. On Earth, sulfur is commonly found in soil, water, and plants. The detection of sulfur on the Moon could indicate the presence of water ice, making the south pole more hospitable than previously assumed. Space agencies globally are keenly interested in the south pole, envisioning it as a potential site for a permanent lunar base. Earlier studies suggested the existence of ice water reservoirs in the Moon’s south pole, valuable for both consumption and fuel.
Chandrayaan-3’s triumphant lunar landing on August 23 positioned India among elite spacefaring nations, following the Soviet Union, the U.S., and China. The mission’s duration aligns with a full lunar day, spanning 14 days, during which sunlight illuminates the Moon. In its early stages, Chandrayaan-3 assessed the lunar south pole’s temperature profile, enhancing our understanding of its thermal dynamics. India’s lunar endeavors have already yielded significant scientific dividends.
The rover’s images and findings have been a testament to India’s advanced space capabilities. The in situ measurements by Chandrayaan-3 have unambiguously confirmed sulfur’s presence, a feat unachievable by orbiting instruments. The rover, named Pragyan, which translates to “Wisdom” in Sanskrit, will continue to explore the largely unmapped south pole. Transmitting images and data, Pragyan will operate for approximately two weeks, powered by solar energy.
