1.Inception
In 2007, India signs a deal with the Russian premier space agency Roscosmos to jointly design the Chandrayaan-2, after the success of the Chandrayaan-1 spacecraft.
The two countries finished the design by August, around the time which the Chandrayaan-1 mission officially ended. However, later Russia says they cannot provide the Chandrayaan-2 lander by 2015, to India's disagreement.
In 2013, India decides to go the moon landing route alone and carry on the entire project indigenously from the country.
The spacecraft's launch had been scheduled for March 2018 but was delayed to conduct further tests on the vehicle. On 19 June 2018, a number of changes in configuration and landing sequence were planned for implementation, pushing the launch to the first half of 2019.
