Chandrayaan-2 guided Japan's SLIM mission to land on the Moon.
Japan used India's Chandrayaan-2 to collect imagery that helped choose a landing location for the spacecraft.
Chandrayaan-2's technological advancements and experiences have provided valuable insights for SLIM, which successfully landed on the Moon on Saturday.
The Chandrayaan-2 mission was partially successful as it failed to land on the Moon, but its orbiter is still hovering over the lunar surface today.

When the mission landed on the Moon, it did not perform as expected as the latest imagery shows that it stopped its solar panels from charging.
The Japanese space agency has said it will take several months to assess whether it landed accurately, just 100 meters from the landing site.
