Chandrayaan-3 is an ambitious lunar exploration mission by the Indian Space Research Organisation (ISRO).

It successfully landed on the unexplored south pole of the moon, making India the first country to achieve this remarkable feat, especially after Russia's Luna-25 failed in a similar mission.

This achievement comes after a failed attempt in 2019, where the Chandrayaan-2's lander crashed on the lunar surface. The successful landing of Chandrayaan-3 has been hailed as India's most significant scientific accomplishment. The rover, named "Pragyan", is equipped with instruments to conduct element and chemical composition experiments and a robotic path planning exercise for future exploration. It is expected to remain functional for two weeks, which is one lunar day, the duration its solar-powered equipment is designed to last.

The mission faced potential challenges, especially from lunar dust, which could impact the rover's moving parts. Lunar dust is different from Earth's and could stick to the rover's materials, potentially affecting its operation. It was accomplished with a budget of about 6.15 billion rupees (approximately $75 million). The lunar south pole is of particular interest because of its water ice, which could be a source of fuel, oxygen, and drinking water for future missions. However, the rough terrain of the south pole makes landing there challenging.

What is the Historic Importance of Chandrayaan 3?

Chandrayaan-3's successful landing has positioned India as a leading space power, enhancing its reputation for cost-competitive space engineering. The mission has boosted India's standing on the global stage and has been seen as a significant moment of national pride. The landing has also been recognized as an achievement for all of humanity, with Prime Minister Narendra Modi emphasizing its global significance.

India is now the fourth country, after the United States, the former Soviet Union, and China, to achieve a successful lunar landing. The Chandrayaan-3 mission has the potential to provide valuable scientific data about the moon's makeup, especially the south polar region, which is believed to harbor significant amounts of water ice. This information could be crucial for future crewed missions to the moon.

The success of Chandrayaan-3 could also pave the way for more significant achievements in India's space.
