Detection of sulphur, other elements will help unveil Moon's geological mysteries: experts
New Delhi (PTI): What was known in theory has now been confirmed twice. The Chandrayaan-3 mission has authenticated the presence of sulphur on the lunar south pole region after on site tests, a historical first that could provide clues to the origins of the Moon and also have profound significance for space exploration, say scientists.
On Thursday, India's space agency ISRO said the Alpha Particle X-ray Spectroscope (APXS) instrument onboard the Pragyan rover confirmed the presence of sulphur and some other elements in the lunar south. Before that, on Tuesday, ISRO announced that another instrument, the Laser-Induced Breakdown Spectroscope (LIBS), found sulphur in the region.
In line with expectations, ISRO also reported the LIBS instrument had detected aluminium, calcium, iron, chromium, titanium, manganese, silicon and oxygen.
"The elements found on the Moon are not merely isolated compounds. They are time capsules carrying the whispers of cosmic history. Such findings not only reshape our comprehension of lunar formations but also offer potential prospects for lunar exploration and habitation," Akash Sinha, who was involved in developing software for the Pragyan rover, told PTI.
"One prevailing theory is that the sulphur may be trapped within water ice, implying that we might be on the brink of a monumental discovery: the physical presence of water ice on the moon," the professor of practice at Shiv Nadar Institution of Eminence in Delhi-NCR added.
An old undated document from the US space agency NASA suggested the potential utilisation of sulphur for making lunar bricks or concrete using it with moon soil. Interestingly, China's reported plans to test printing bricks from lunar soil this decade for constructing a permanent moon base align with this idea.
The revelation of sulphur's presence might hold clues to the Moon's composition and its volcanic past, scientists said.
"Surface sulphur comes from volcanic activity, indicating heavy volcanism at some point in the Moon's history. However, the detection is from only one spot, so we need more data to gain a clearer picture," said T V Venkateswaran, a scientist at Vigyaan Prasar, an autonomous organisation under the Department of Science and Technology (DST).
Sinha added that the discovery of sulphur represents a significant breakthrough in the understanding of lunar geology.
"The presence of sulphur, especially in an area where volcanic activity a common source of sulphur is notably absent opens up intriguing possibilities about the origins of the Moon," he said.
According to astrophysicist Sandip Chakrabarti, the in-situ measurements definitively confirm sulphur's presence in the region, a feat beyond the capabilities of the instruments on the previous Chandrayaan 1 and 2 orbiters.
"The compositions show abundant lighter metals such as aluminium and also abundant sulphur and iron. Sulphur could come from lunar volcanoes. Only traces of heavy metals such as titanium, and chromium, were found. These are along the expected lines," Chakrabarti, director of the Indian Center for Space Physics in Kolkata, told PTI.
These elements, he explained, aren't in their pure form and would need processing for future extraction.
"The discoveries made by Chandrayaan-3 hold vast implications for lunar exploration. Beyond the allure of space travel, the presence of these elements paints a vivid picture of the Moon's character," Chakrabarti reflected.
Experts also believe that aluminium's lightweight strength could become a resource for future missions, potentially transforming the Moon into a launchpad for further space exploration. Calcium's critical role in biological processes could fuel discussions about the Moon's potential as a scientific research hub.
Chakrabarti expressed his enthusiasm for Pragyan's contribution. "It is indeed heartening that Pragyan is actually sending the composition of the topsoil of the landing area, namely, Shiv-Shakti point."
He also highlighted the need for helium, hydrogen and water for future space travel, survival and power generation.
"Right now, we are concentrating on survival on the Moon and not getting richer," he added.
ISRO has initiated a thorough investigation into the presence of hydrogen.
Venkateswaran, who is also a member of the outreach committee of the Astronomical Society of India, emphasised the rover's role in confirming a finding from Chandrayaan-1 about hydrogen particles reflected by the Moon's surface in 2008.
"We do need to see water in any of its forms and hydrogen. That would be a genuine achievement," Chakrabarti added.
Chandrayaan-3 touched down on the lunar south pole on August 23, making India the first country to land on the uncharted surface.

Pune accident: Porsche car's registration was pending since March due to non-payment of Rs 1,758 fee
Mumbai, May 21: The permanent registration of the luxury Porsche car involved in the accident in which two IT professionals were fatally knocked down by in Pune city was pending since March due to non-payment of Rs 1,758 fees by the owner, top officials of the Maharashtra transport department said on Tuesday.
The electric luxury sports sedan - Porsche Taycan - was being driven allegedly by a prominent builder's 17-year-old son, who the police claim was drunk at the time of the accident that took place in Kalyani Nagar area in the early hours of Sunday.
Maharashtra Transport Commissioner Vivek Bhimanwar told PTI that the Porsche car was imported in March by a dealer in Bengaluru and from there it was sent to Maharashtra on a temporary registration.
"When it was produced at the Pune Regional Transport Office (RTO), it was found that a certain registration fee was not paid and the owner was asked to pay the amount for completion of the procedure. However, the vehicle was not brought to the RTO for the completion of the registration process after that," he said.
According to officials, road tax is exempted for electric vehicles registered in Maharashtra, and hence for the registration of this Porsche Taycan model, the registration fees that were applicable were only Rs 1,758 with the break-up of Rs 1,500 hypothecation fees, Rs 200 smart card RC fees and Rs 58 postal charges.
Interestingly, as per Porsche India's website, the ex-showroom price of the vehicle manufacturer's various cars starts at Rs 96 lakh and goes over Rs 1.86 crore. Though the price of the Porsche Taycan model is not given on the website, transport department sources said that it could be in crores.
The officials said that as per their records, the vehicle had a valid temporary registration certificate issued by Karnataka with a validity of six months from March to September 2024.
They said that the Porsche dealer in Bengaluru was not at fault as he had handed over the car after doing the temporary registration. Hence, it was the responsibility of the owner to get it registered at the RTO before plying it on the roads. During the temporary registration period, the vehicles can only be used to drive to and from the RTO.
Bhimanwar said that the teenage boy, who was said to be driving the car, will be barred from getting a driving licence until he turns 25 years of age, and the luxury car will also not be allowed to register at any RTO office for 12 months as its existing temporary registration will be cancelled as per the provisions in the Motor Vehicles (MV) Act.
Under the sub-sections of Section 199A (offenses by juveniles) of the MV Act, the transport authorities can take this action.
Bhimanwar said that their department is going to take stringent action in this case and the Pune RTO has been asked to register the police complaint for violation of provisions in the MV Act
"Whatever violations related to the Motor Vehicles Act happened in the issue, those will be registered in the FIR," Bhimanwar said, adding that they will also invoke the procedure for cancellation of the temporary registration of the vehicle as per the provisions in the act.
"The vehicle will be impounded for 12 months," another top official of the transport department said, adding that there is gross negligence in this case as the vehicle was driven at a speed over 160 kmph, allegedly in an inebriated state as per media reports.
The official said that there are several violations in this case, including driving the vehicle without a driving licence and without its registration, among others.
Meanwhile, Maharashtra Deputy Chief Minister and Home Minister Devendra Fadnavis said in a press conference in Pune this evening that the car was purchased in Bengaluru and was brought here.
"As per the primary information, the RTI had carried out its inspection but the tax which was required to be paid was not paid. If there is any violation regarding that, a separate FIR will be registered," he said.
