The Laser-Induced Breakdown Spectroscope instrument onboard ‘Pragyan‘ rover of Chandrayaan-3 has unambiguously confirmed the presence of sulphur on the lunar floor close to south pole, by means of first-ever in-situ measurements, ISRO mentioned on Tuesday.
It additionally mentioned the instrument additionally detected aluminium, calcium, iron, chromium, titanium, manganese, silicon and oxygen, as anticipated.
“The Laser-Induced Breakdown Spectroscopy (LIBS) instrument onboard Chandrayaan-3 Rover has made the first-ever in-situ measurements on the elemental composition of the lunar surface near the south pole. These in-situ measurements confirm the presence of Sulphur (S) in the region unambiguously, something that was not feasible by the instruments onboard the orbiters,” the house company mentioned in a press release.
According to ISRO, LIBS is a scientific method that analyses the composition of supplies 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. The collected plasma light is spectrally resolved and detected by detectors such as Charge Coupled Devices. Since each element emits a characteristic set of wavelengths of light when it’s in a plasma state, the elemental composition of the material is determined,” it mentioned.
Preliminary analyses have unveiled the presence of Aluminum (Al), Sulphur (S), Calcium (Ca), Iron (Fe), Chromium (Cr), and Titanium (Ti) on the lunar floor. Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O), it mentioned.
“Thorough investigation regarding the presence of Hydrogen is underway,” ISRO mentioned.
LIBS instrument is developed on the Laboratory for Electro-Optics Systems at Peenya Industrial Estate, Bengaluru the place the primary India satellite tv for pc was fabricated in 1975.
India on August 23 scripted historical past as ISRO’s bold third Moon mission Chandrayaan-3’s Lander Module (LM) touched down on the lunar floor, making it solely the fourth nation to perform the feat, and first to succeed in the uncharted south pole of Earth‘s solely pure satellite tv for pc.
Prime Minister Narendra Modi on Saturday introduced the choice to call the spot the place Chandrayaan-3 Vikram lander made delicate touchdown as ‘Shiv Shakti Point’ and the location the place the Chandrayaan-2 lander crash-landed on the Moon’s floor in 2019 could be generally known as “Tiranga Point”.
Also, August 23, the day the Chandrayaan-3 lander touched down on the lunar floor, could be celebrated as ‘National Space Day’, Modi had mentioned.
