“LIBS is a scientific technique that analyzes the composition of materials by exposing them to intense laser pulses. A high-energy laser pulse is focused on the surface of a material, such as rock or soil. The laser pulse generates extremely hot, localized plasma,” Isro said.
The collected plasma light is spectrally analyzed and detected by detectors such as charge-coupled devices. “Because each element emits a distinct set of wavelengths of light when in the plasma state, the elemental composition of the material is determined,” Isro added.

The space agency said that preliminary analyzes, represented graphically, revealed the presence of aluminum (Al), sulfur (S), calcium (Ca), iron (Fe), chromium (Cr), and titanium (Ti) on the surface of the moon. .
Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O). hydrogen “Now,” said Isru.
The LIBS instrument was developed at the Laboratory of Electro-Optical Systems (LEOS) in Bengaluru. LEOS, a vital unit of Isro, handles the design, development and production of attitude sensors for all LEO, GEO and interplanetary missions; It develops and delivers optical systems for remote sensing and meteorological payloads.
“The lab is equipped with world-class manufacturing, testing and coating facilities. Next-generation technologies such as three-axis fiber optic gyroscopes, optical communications, MEMS systems, nanotechnology, detectors, and development of science payloads for future space missions are also being pursued.
