Pragyan rover discovers sulphur at moon’s south pole | Explained
The HinduIn an exciting milestone for lunar scientists around the globe, India’s Chandrayaan-3 lander touched down 600 km from the south pole of the moon on August 23, 2023. While the data from Chandrayaan-3’s rover, named Pragyan, or “wisdom” in Sanskrit, showed the lunar soil contains expected elements such as iron, titanium, aluminum and calcium, it also showed an unexpected surprise – sulphur. Sulphur in soils near the moon’s poles might help astronauts live off the land one day, making these measurements an example of science that enables exploration. The uncalibrated data collected by the LIBS instrument on Pragyan suggests that the moon’s highland soils near the poles might have a higher sulphur concentration than highland soils from the equator and possibly even higher than the dark volcanic soils. Astronauts and robots could travel from the south pole base to collect, process, store and use naturally occurring materials like sulphur on the moon – a concept called in-situ resource utilisation.
