Chandrayaan-3 lifted off on July 14, and is scheduled to land on the Moon on August 23. That is as I calculate a travel time of 40 days.
Just to put it in perspective and to show the advancement of technology and science, how long did it take Apollo 11 some 54 years ago, to reach the Moon?
About three days. But this isn't really about technology... which in terms of rockets, hasn't changed all that much. With an unmanned mission, there is no need for speed, so it makes sense to choose much more energy efficient trajectories. Our travel time now for a manned mission would be similar to what it was in the Apollo era. Indeed, the upcoming Artemis crewed lunar flights have about 4-day trip times.
