Pragyan has been put to sleep in Chandrayaan-3

  • Chandrayaan-3 achieved India’s historic soft landing on the Moon’s South Pole.
  • Since its landfall on August 23, the mission has been highlighted by several notable observations.

Chandrayaan-3’s: Significant Achievements

  • The Laser-Induced Breakdown Spectroscopy (LIBS) sensor on the Pragyan rover detected elements like as aluminium, sulphur, calcium, iron, and others.
  • The Vikram lander observed a’moonquake’ and an ultra-thin layer of plasma in the lunar atmosphere.
  • These studies suggest that the moon’s atmosphere differs from that of Earth.

The Importance of Observations

  • The discovery of sulphur is critical to understanding the moon’s formation and prior surface (explosiveness) conditions.
  • Significant levels of sulphur can provide insights into lunar volcanic activity, potentially indicating the presence of underground water.
  • The presence of sulphur could provide information about prior lunar life support and the construction of structures for human settlement.

Examining Lunar Water

  • The findings of Chandrayaan-3, particularly those concerning sulphur and oxygen on the moon’s surface, are significant in narrowing down probable water sources.
  • The presence of sulphur and oxygen increases the likelihood of finding water.
  • ISRO was hoping for information on lunar hydrogen, which might be another indicator of water.

Other responsibilities Discoveries on the Moon

  • The Chang’e 5 mission from China discovered a new lunar mineral, Changesite-(Y), and discovered water in glass beads.
  • The sulphur finding of Chandrayaan-3 corresponds to the search for comparable glass beads.
  • NASA has confirmed the presence of lunar water in both dark and bright craters.

The current status of the Ch-3 Mission

  • The major objectives of Chandrayaan-3 have been met; the Pragyan rover has been placed in’sleep’ mode.
  • The solar panels of the rover will recharge during the next lunar sunrise.
  • Plans to restart the rover for additional observations are still in the works.
