Chandrayaan-3 rover confirms presence of sulphur on lunar surface,search for Hydrogen underway: ISRO
Bengaluru, Aug 29: The Laser-Induced Breakdown Spectroscope instrument onboard 'Pragyan' rover of Chandrayaan-3 has unambiguously confirmed the presence of sulphur on the lunar surface near south pole, through first-ever in-situ measurements, ISRO said on Tuesday.
It also said the instrument also detected aluminium, calcium, iron, chromium, titanium, manganese, silicon and oxygen, as expected.
"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 space agency said in a statement.
According to ISRO, 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. 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 said.
Preliminary analyses 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), it said.
"Thorough investigation regarding the presence of Hydrogen is underway," ISRO said.
LIBS instrument is developed at the Laboratory for Electro-Optics Systems at Peenya Industrial Estate, Bengaluru where the first India satellite was fabricated in 1975.
India on August 23 scripted history as ISRO's ambitious third Moon mission Chandrayaan-3's Lander Module (LM) touched down on the lunar surface, making it only the fourth country to accomplish the feat, and first to reach the uncharted south pole of Earth's only natural satellite.
Prime Minister Narendra Modi on Saturday announced the decision to name the spot where Chandrayaan-3 Vikram lander made soft landing as 'Shiv Shakti Point' and the site where the Chandrayaan-2 lander crash-landed on the Moon's surface in 2019 would be known as "Tiranga Point".
Also, August 23, the day the Chandrayaan-3 lander touched down on the lunar surface, would be celebrated as National Space Day', Modi had said.

Jharkhand horror: Man kills live-in partner, chops body into 40 pieces
Ranchi (PTI): A 25-year-old man, who works as a butcher, allegedly strangled to death his live-in partner and chopped her body into 40 to 50 pieces in a forested area in Jharkhand’s Khunti district, police said on Wednesday.
The accused, identified as Naresh Bhengra, was arrested.
The matter came to light after around a fortnight after the killing when a stray dog was found with human body parts near Jordag village in Jariagarh police station on November 24.
Bhengra was in a live-in relationship with the deceased, a 24-year-old woman also from Khunti district, in Tamil Nadu for the past couple of years. Sometime back, he returned to Jharkhand, got married to another woman without telling his partner anything and went back to the southern state without his wife to join her.
"The brutal incident occurred on November 8 when they reached Khunti as the accused who had married another woman did not wish to take her home. Instead, he took her to a forest near his house at Jordag village in Jariagarh police station and chopped the body into pieces. The man has been arrested," Khunti Superintendent of Police Aman Kumar told PTI.
Inspector Ashok Singh who investigated the case said the man worked in a butcher shop in Tamil Nadu and was expert in slicing chicken.
“He admitted chopping the body parts of the woman into 40 to 50 pieces before leaving those in the forest for wild animals to feast on. The police recovered several parts on November 24 after a dog in the area was seen with a hand," Singh told PTI.
Singh said that the woman, who was unaware of his marriage, pressured him to return to Khunti. After reaching Ranchi, they boarded a train on November 24 and headed to the man's village.
"Under a plan, the man took her to Khunti in an autorickshaw near his home and asked her to wait. He returned with sharp weapons and strangulated her with her dupatta after raping her. He then cut the body into 40 to 50 pieces and left for his home to live with his wife," Singh said.
The woman, however, had informed her mother that she had boarded a train and would be living with her partner, the police officer said.
Following the recovery of body parts, a bag was also found in the forest with the murdered woman's belongings including her Aadhaar card. The mother of the woman was called at the spot and she identified her daughter's belongings.
"The mother suspected the man behind the crime who after being nabbed by the police admitted to chopping the woman into pieces," the official added.
The incident has sent shockwaves among people in the region, with the Shraddha Walker murder case of 2022 still fresh in their memory.
Walker was killed by her live-in partner who chopped her body into pieces before dumping them in the jungle in South Delhi’s Mehrauli.
