ISRO did not send a river to the moon. The spacecraft that India sent to the moon is called Chandrayaan-3. It is a lunar exploration mission that includes a lander, a rover, and an orbiter. The lander is named Pragna, which means "wisdom" in Sanskrit. It is designed to land on the moon and deploy the rover, which will explore the lunar surface. The orbiter will study the moon from orbit and provide communication support for the lander and rover.

The orbiter will study the moon from orbit and provide communication support for the lander and rover.

The life of Pragna on the moon is expected to be limited. The lander is not designed to last for an extended period of time, and it is likely to only operate for a few weeks or months. The rover is expected to last longer, but it is still not clear how long it will be able to operate.

The main purpose of Pragna is to test India's ability to land a spacecraft on the moon and to deploy a rover. The mission is also expected to gather scientific data about the moon, such as its composition and surface features.
