Chandrayaan is the Indian space agency ISRO’s lunar exploration mission. The first Chandrayaan mission was launched on October 22, 2008. Later in 2019, the second launch took place. As the name suggests, the Chandrayaan mission is a journey to the moon. One day some Indian citizen will land on the moon in ISRO’s vehicle. Chandrayaan will be seen as a preparation for that.
ISRO is actually testing the capabilities of its technologies for lunar exploration. Preparing for flawless future missions.
Chandrayaan 3 has three main objectives.
Enable a safe soft landing on the lunar surface Move the rover on the moon Conduct various scientific experiments at the landing site
In order to achieve these objectives, the lantern incorporates a number of technologies such as altimeters, velocimeters, inertial measurement systems, propulsion systems, navigation, guidance and control systems, accident detection and avoidance systems, and landing leg mechanisms.
Scientific studies and their tools
The Radio Anatomy of the Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA) system on board the Lunar will examine the plasma (ions and electrons) concentration and changes in the lunar surface. Measurements of the thermal properties of the lunar surface near the polar region will be made using the Chandra Surface Thermophysical Experiment (ChaSTE) system.
The Lunar Seismic Activity Instrument is also on board to measure earthquakes around the landing site and to define the composition of the Moon’s crust and mantle. The lantern also has a laser retroreflector array for studying the dynamics of the lunar system.
Apart from this, the rover is also equipped with the Laser Induced Breakdown Spectroscope and the Alpha Particle X-ray Spectrometer to study lunar soil and rocks and to study chemical properties.

There are two parts to the launch. The first propulsion module will carry the Lantern module into lunar orbit. The lunar lander is the Lantern Module. The rover is placed within this. The propulsion module weighs 2148 kg and the lantern module weighs 1752 kg. The weight of the rover is 26 kg. Mission duration is one lunar day. It takes 14 days on Earth.
