The Laser-Induced Breakdown Spectroscope (LIBS) instrument onboard Chandrayaan-3 rover Pragyan has unambiguously confirmed the presence of Sulphur (S) in the lunar surface near the south pole, ISRO confirmed today.
“LIBS is a scientific technique that analyses the composition of materials by exposing them to intense laser pulses. A high-energy laser pulse is focused onto the surface of a material, such as a rock or soil. The laser pulse generates an extremely hot and localised plasma,” Isro said.
Preliminary analyses, graphically represented, have unveiled the presence of Aluminum (Al), Sulphur (S), Calcium (Ca), Iron (Fe), Chromium (Cr), and Titanium (Ti) on the lunar surface. Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O).
Investigation regarding the presence of Hydrogen is still underway.
Apart from stumbling upon giant craters in the south polar region, the Pragyan rover has also found massive temperature variations on the lunar surface.
