The Chandrayaan-3 mission consists of three main components:

The Orbiter: The orbiter is the largest and most complex component of the mission. It will orbit the Moon at an altitude of about 100 kilometers. The orbiter will carry a number of scientific instruments, including a high-resolution camera, a spectrometer, and a magnetometer. These instruments will be used to study the Moon’s surface, atmosphere, and interior.
The Lander: The lander is the second largest component of the mission. It will soft-land on the Moon’s south pole. The lander will carry a number of scientific instruments, including a drill, a seismometer, and a thermal mapper. These instruments will be used to study the lunar surface and to search for water ice.
The Rover: The rover is the smallest component of the mission. It will be deployed by the lander and will explore the lunar surface for up to 14 days. The rover will carry a number of scientific instruments, including a camera, a spectrometer, and a magnetometer. These instruments will be used to study the lunar surface and to search for water ice.
The Chandrayaan-3 mission is designed to address several scientific objectives, including:

Studying the composition of the Moon’s south pole: The Moon’s south pole is thought to be a good place to search for water ice, because it is permanently shaded from the Sun. The Chandrayaan-3 mission will use its instruments to study the composition of the lunar surface in the south pole region, in order to search for water ice.
Searching for water ice on the Moon: Water ice is a valuable resource for future human missions to the Moon. The Chandrayaan-3 mission will use its instruments to search for water ice in the lunar regolith, or soil.
Investigating the Moon’s geology and history: The Moon’s surface is covered in craters, which provide clues about the Moon’s history. The Chandrayaan-3 mission will use its instruments to study the Moon’s geology and history.
Preparing for future human missions to the Moon: The Chandrayaan-3 mission will help India to develop the technologies and experience needed for future human missions to the Moon.
The Chandrayaan-3 mission is a major milestone for India’s space program. It is the first Indian mission to attempt a soft landing on the Moon’s south pole. The success of the Chandrayaan-3 mission will help India to become a leading player in lunar exploration.

The Chandrayaan-3 mission is scheduled to land on the Moon on August 23, 2023. ISRO is confident that the mission will be a success.
