Chandrayaan 3 Mission :

Chandrayaan-3 was a planned lunar exploration mission by the Indian Space Research Organisation (ISRO). It aimed to achieve a successful soft landing on the Moon’s surface, similar to its predecessor Chandrayaan-2’s Vikram lander. The mission’s primary focus was on the technology and engineering aspects of landing on the lunar surface. Chandrayaan-3’s objectives included demonstrating India’s capability to achieve a precise and controlled lunar landing, studying the Moon’s surface composition, mineralogy, and topography, and enhancing our understanding of the Moon’s geological history and evolution. The mission was expected to include a lander and rover, equipped with scientific instruments to analyze the Moon’s surface and gather valuable data. By studying the Moon’s surface in greater detail, Chandrayaan-3 aimed to contribute to our knowledge of the Moon’s formation and shed light on various lunar phenomena.

Chandrayaan 3 Mission Highlights : Chandrayaan-3 was launched from a space center in Sriharikota, India. After traveling for 40 days, it landed on the Moon. On August 23, at 6:04 PM Indian time, the Vikram lander successfully landed on the Moon. The Indian Space Research Organisation (ISRO) keeps a close watch on the mission to make sure everything is going well. The Pragyan rover will begin its tasks on the Moon soon. Chandrayaan-3 is a follow-up to Chandrayaan-2 from 2019. Its main goal is to gently land on the Moon’s surface. This achievement puts India in the company of other space leaders like the US, the Soviet Union, and China. The mission’s last moments, known as the “15 minutes of terror,” were divided into four phases that led to the soft landing.
