PANAJI: The Indian Space Research Organisation (ISRO) on Tuesday said the Pragyan rover’s Laser-Induced Breakdown Spectroscope confirmed the presence of sulphur in the lunar surface near the south pole, through the first-ever in-sity measurements.
ISRO said the rover’s spectroscope also detected Aluminium, Calcium, Ferrous (Iron), Chromium, Titanium, Manganese, Silicon and Oxygen as expected. The search for hydrogen is underway.“Preliminary analyses, graphically represented, 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). Thorough investigation regarding the presence of Hydrogen is underway”, ISRO said in its statement.
LIBS instrument is developed at the Laboratory for Electro-Optics Systems (LEOS)/ISRO, Bengaluru”, ISRO added.The developments come after the Indian space agency said the Pragyan rover was “on way to uncover more secrets” of the moon.
The rover was ramped out of the ‘Vikram’ lander hours after the Chandrayaan 3’s successful landing on the moon’s south pole on August 23. On August 26, ISRO had released a video of the rover roaming around the ‘Shiv Shakti’ Point, the landing point of the Chandrayaan 3.
““Chandrayaan-3 Mission:What’s new here? Pragyan rover roams around Shiv Shakti Point in pursuit of lunar secrets at the South Pole ! ISRO had posted on X.Yesterday, the space agency said that the Pragyan rover came across a four-metre diameter crater positioned 3 meters ahead of its location on the lunar surface yesterday.“
On August 27, 2023, the Rover came across a 4-meter diameter crater positioned 3 meters ahead of its location. The Rover was commanded to retrace the path. It’s now safely heading on a new path”, ISRO had said.India achieved history on August 23 by becoming the first country to touch down on the moon’s South Pole
India’s Chandrayaan-3, since its successful landing on the Moon on August 23, has been making several ground-breaking discoveries. Apart from stumbling upon giant craters in the south polar region, the Pragyan rover has also found massive temperature variations on the lunar surface.
During its observation of lunar top soil, the rover’s ChaSTE (Chandra’s Surface Thermophysical Experiment) instrument found that the temperature on the surface of the Moon was around 50 degrees Celsius, and it increased to over 60 degrees at the height of 20mm. At minus 80mm depth, which is below the ground, the temperature dropped to minus 10 degrees Celsius.
The ChaSTE measures the temperature profile of the lunar topsoil around the pole to understand the thermal behaviour of the moon’s surface. It has a temperature probe equipped with a controlled penetration mechanism capable of reaching a depth of 10 cm beneath the surface. The probe is fitted with 10 individual temperature sensors
