Days after Nana Patekar's death, old friend and actor Susmita Mukherjee remembered him with a soul-stirring tribute. Sharing pictures from Deepti Naval's birthday party on 3rd of February, 1991, Sushmita mused over the lost time, innocence and moments that became intrinsically attached with persons who were part of the memory. "Just the four of us. Wine, music, laughter, and even a piano. A little world of our own, untouched by the complexities of life that lay ahead. "And then, one of us slipped away. We mourned not just the person we had lost, but also the absence of what once was - the moments, the togetherness, the innocence, and a time we could never return to," wrote Susmita. Susmita recalled the bygone time when a dear friend of 38 years sent her a bunch of photographs. "The memories were hazy, the details blurred by time. But the moment I looked at those photographs, something magical happened. They awakened a part of my brain where memor...
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.
