The Vikram lander was 100 kilometers away from LRO, near Manzinus crater in the Moon's south pole region, when LRO transmitted laser pulses toward it on December 12 last year.
The Lander and the Rover have scientific payloads to carry out experiments on the lunar surface. The main function of the Propulsion Module (PM) was to carry the Lander Module (LM) from the launch vehicle injection till final lunar 100 km circular polar orbit and separate the LM from PM, which it did.
Luna-25 took off from the Vostochny launch facility in Russia's Far East, Russia-based TASS news agency reported.
