India’s space agency is embarking on a mission to achieve a historic landing on the moon’s south pole, a venture poised to propel the country’s space ambitions and extend our understanding of lunar water ice—a potentially invaluable lunar resource. This endeavor holds implications for lunar colonies, mining prospects, and even future expeditions to Mars.
Lunar Water Ice
From India’s space agency to private enterprises, the moon’s south pole has emerged as a focal point of exploration, holding the promise of significant advancements. The pursuit of a moon landing aligns with India’s broader space aspirations and the allure of tapping into lunar water ice.
Historical Insights
As early as the 1960s, prior to the inaugural Apollo moon landing, scientists had speculated about the potential presence of water on the moon. However, initial assessments of samples returned by Apollo crews suggested a lack of water. In a pivotal discovery in 2008, researchers at Brown University utilized innovative technology to reexamine lunar samples, revealing the existence of hydrogen within minuscule beads of volcanic glass. Subsequently, in 2009, a NASA instrument aboard the Indian Space Research Organisation’s Chandrayaan-1 probe confirmed the existence of water on the moon’s surface. The same year witnessed another significant revelation as a NASA probe striking the south pole unveiled the presence of water ice beneath the lunar surface. A prior NASA mission, the 1998 Lunar Prospector, had also indicated that water ice concentrations were highest within the shadowed craters of the moon’s south pole.
Significance of Lunar Water Ice
The intrigue surrounding lunar water ice is underpinned by its potential implications. The pockets of ancient water ice offer a window into lunar volcanic history, the materials brought to Earth by comets and asteroids, and the origins of Earth’s oceans. If present in substantial quantities, lunar water ice could serve as a reservoir for drinking water during moon exploration and could contribute to equipment cooling. Moreover, its breakdown could yield hydrogen for fuel and oxygen for breathing, thereby supporting Mars missions and lunar mining.
Navigating International Regulations and Commercial Endeavors
The 1967 United Nations Outer Space Treaty forbids any nation from asserting ownership over the moon. Despite this, there are no explicit provisions that restrict commercial operations. An initiative led by the United States, known as the Artemis Accords, aims to establish guidelines for moon exploration and resource utilization, boasting 27 signatory nations. Notably, China and Russia have yet to endorse this initiative.
Complexities of the Moon’s South Pole
The moon’s south pole presents a formidable challenge for lunar landings, as evidenced by past failures. Recently, Russia’s Luna-25 craft, scheduled for a south pole landing, veered off course and crashed. The region’s topography, characterized by craters and deep trenches, differs substantially from the equatorial sites targeted in previous endeavors, including the historic Apollo missions. India’s space agency, ISRO, remains undeterred, progressing toward a landing attempt through its Chandrayaan-3 mission. An earlier Indian mission in 2019 had faltered in its landing near the intended Chandrayaan-3 target. Concurrently, both the United States and China have outlined their own lunar south pole missions.
