How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- The crater 'McGetchin' was identified by NASA on the surface of the Moon.
- It measures approximately 222 metres (730 feet) in diameter.
- It is believed to have been created by a comet or asteroid impact around 2024.
- It was detected through repeat satellite imaging of the lunar surface.
ಮೇನ್ಸ್
GS Paper 3 - Science & Technology / Space exploration: the ability to detect a fresh lunar impact only through repeat satellite imaging highlights how dynamic and under-monitored the Moon's surface still is. This has implications for planning the landing-site safety of future lunar missions and for tracking near-Earth comet/asteroid activity, pointing to the need for sustained international lunar surface monitoring and data-sharing.
