Part of: Prelims and GS III – Awareness in space.
Context The Orbiter and other instruments of Chandrayaan-2 mission have, in two years, gathered a wealth of new information that has added to our knowledge about the Moon and its environment.
What happened to Chandrayaan-2?
- Chandrayaan-2, India’s second mission to the Moon, had failed to make a soft-landing on the lunar surface.
- The lander and rover malfunctioned in the final moments and crash-landed, getting destroyed in the process.
Why is this mission still relevant?
- Despite the failure, the mission’s orbiter and other parts have been functioning normally, gathering information.
- Recently, the ISRO released the information gathered by the scientific payloads till now, some of which were still to be analysed and assessed.
Key information gathered from Chandrayaan-2
- Presence of water molecules on moon which is the most precise information about water till date.
- Presence of Minor elements: Chromium, manganese and Sodium have been detected for the first time through remote sensing.
- Information about solar flares: A large number of microflares outside the active region have been observed for the first time. It shall help in understanding the mechanism behind heating of the solar corona.
