Here are the important points about Chandrayaan:
Chandrayaan-1:
This was India's first lunar mission, launched on October 22, 2008. It made significant contributions to lunar science, including the discovery of water molecules on the Moon's surface and the identification of various lunar minerals.
Chandrayaan-2:
Chandrayaan-2 is the second lunar exploration mission by India and is more ambitious than its predecessor. It consists of an orbiter, a lander (Vikram), and a rover (Pragyan). It was launched on July 22, 2019.
Orbiter:
The Chandrayaan-2 orbiter continues to orbit the Moon and study its surface and exosphere. It carries eight scientific instruments to perform remote-sensing observations.
Vikram Lander:
The Vikram lander was designed to make a soft landing on the Moon's surface near the south pole. Unfortunately, it lost communication with ISRO during its descent and crash-landed in September 2019. This was a setback, but the orbiter remains operational and continues to send valuable data.
Pragyan Rover:
The Pragyan rover was designed to explore the lunar surface, analyze soil samples, and conduct experiments. However, due to the failure of the Vikram lander, the rover was not deployed.
Scientific Objectives:
Chandrayaan-2 aimed to study the lunar surface, mineral composition, topography, and the distribution of lunar water. These objectives were to improve our understanding of the Moon's geological history and its potential for resources like water ice.
Water Discovery:
Chandrayaan-1 and Chandrayaan-2 both contributed to the discovery of water molecules on the Moon. This finding has significant implications for future lunar exploration and the possibility of sustaining human presence on the Moon.
International Collaboration:
Chandrayaan missions have involved international collaborations. For instance, Chandrayaan-1 had NASA's Moon Impact Probe, and Chandrayaan-2 included payloads from various countries.
