India’s Moon missions:

India had launched several missions on the moon. The first one is Chandrayaan-1 which launched in 2008 by ISRO (Indian Space Research Organisation) from Indian spaceport Shreeharikota.

It consists of three probes the Vikram (lander), Pragyan (rover), and one orbiter. The orbiter was a success but the lander at the time of landing the communication link was broken, leads to the crash of it. ISRO accepts the failure and starts investigating the reason for the failure. The orbiter starts sending pictures of the moon.
