India’s space agency, ISRO, has achieved a significant milestone as its moon rover, ‘Pragyan,’ has successfully identified elements like oxygen, aluminium, and sulphur near the moon’s southern pole. This groundbreaking discovery was made possible through the advanced Laser-Induced Breakdown Spectroscopy (LIBS) tool onboard the Chandrayaan-3 rover.
Unveiling Lunar Composition
The LIBS technique involves using intense laser pulses to analyze materials. These pulses create localized plasma on the material’s surface, emitting unique light wavelengths. By measuring and analyzing this emitted light, scientists can decipher the composition of the lunar surface.
ISRO’s initial investigations reveal the presence of key elements on the moon’s surface, including aluminium (Al), sulphur (S), calcium (Ca), iron (Fe), chromium (Cr), and titanium (Ti). Further studies have also unveiled the existence of manganese (Mn), silicon (Si), and oxygen (O).
New Frontiers of Knowledge
This discovery marks a significant leap forward, especially given that previous orbiting instruments couldn’t offer such detailed insights into specific elements like sulphur. The LIBS tool has opened up new dimensions in lunar exploration and understanding.
As ISRO continues its exploration efforts, further confirmation of hydrogen’s presence in the same area remains a focus.
India’s Chandrayaan-3 mission has taken humanity a step closer to comprehending the moon’s composition. The findings not only expand our knowledge of lunar elements but also underscore the advancements in space technology and exploration achieved by ISRO.
