The Chandrayaan-3 mission has marked a significant breakthrough with the discovery of vital elements in the vicinity of the lunar south pole.
The Indian Space Research Organisation (ISRO) reported that the moon rover, equipped with the Laser-Induced Breakdown Spectroscopy (LIBS) instrument, has successfully identified the presence of aluminium along with other elements in the lunar region near the southern pole.
This momentous finding sheds light on the elemental composition of the Moon's surface and opens avenues for further scientific exploration. The initial analysis of the data collected from the LIBS measurements has unveiled the existence of a diverse array of elements on the lunar surface. These include aluminium (Al), sulphur (S), calcium (Ca), iron (Fe), chromium (Cr), and titanium (Ti). Subsequent measurements have also brought to light the presence of manganese (Mn), silicon (Si), and oxygen (O) in the region. The ongoing investigation is now focused on the identification of hydrogen, a crucial element for a comprehensive understanding of the lunar composition.
The LIBS instrument, developed at the Laboratory for Electro-Optics Systems (LEOS)/ISRO in Bengaluru, has played a pivotal role in this discovery. By employing the LIBS technique, which involves subjecting materials to intense laser pulses, researchers have managed to create a localised plasma on the lunar surface. This plasma emits characteristic wavelengths of light unique to each element, enabling precise identification of their composition.
The Chandrayaan-3 rover, named Pragyan, executed in-situ measurements using the LIBS instrument, providing unprecedented insights into the elemental makeup of the Moon's surface in the specified region. Notably, this achievement surpasses the capabilities of the instruments onboard the orbiters.
Chandrayaan-3's successful landing on the lunar surface on August 23, following a textbook-style approach, demonstrated India's capability to execute complex missions in space. The rover Pragyan, after landing, initiated a series of experiments aimed at unravelling the mysteries of the lunar environment.
Furthermore, this achievement follows India's pioneering revelation of water presence on the Moon during its inaugural moon mission. The continuous advancement of technology and the successful deployment of innovative instruments like the LIBS payload contribute to elevating India's position in space exploration.
