Chandrayaan-3, launched by ISRO, has made significant strides in lunar exploration. One of its remarkable achievements includes the Pragyan rover's use of Laser-Induced Breakdown Spectroscopy (LIBS) to identify key elements such as aluminium, sulphur, calcium, and iron on the moon's surface. Additionally, the Vikram lander captured a 'moonquake' and discovered a super-thin layer of plasma in the lunar atmosphere, shedding light on unique phenomena.
The discovery of elements like sulphur and oxygen is pivotal in enhancing our understanding of the moon's composition. These findings offer insights into the geological history of the moon and its volcanic activity. Such knowledge is vital as it helps scientists explore the moon's origin, assess past conditions that may have supported life, and prepare for future human exploration.
The data collected from the 'moonquake' by the Vikram lander provides a deeper understanding of lunar seismic activities. The detection of a plasma layer in the moon's atmosphere indicates distinct differences in atmospheric characteristics and responses to solar flares when compared to Earth. This information could reshape our understanding of both celestial bodies.
Chandrayaan-3 stands alongside other notable space missions, such as China's Chang’e 5, which revealed new lunar minerals and water in glass beads. Although various missions contribute to a broader understanding of the moon, the discovery of sulphur by Chandrayaan-3 holds the potential for further scientific inquiries and breakthroughs.
Even though Chandrayaan-3 has met its primary objectives, the mission is far from over. The Pragyan rover is currently in a temporary sleep mode to conserve power. As the lunar sunrise approaches, efforts will be undertaken to reactivate the rover for additional observations. The accomplishments of this mission lay the groundwork for ongoing lunar exploration and future endeavors.
While Chandrayaan-3's findings of sulphur and oxygen do not directly confirm the presence of water on the moon, they are instrumental in understanding the elemental composition of the lunar surface. These discoveries provide valuable insights into potential sources and conditions that may lead to significant future findings regarding lunar water.
