I think they created a highly elliptical orbit to get the lander close to the moon's surface and rockets to land when it was at the closest approach. That is very clever.
The ISRO website is more colourful than the other sites I read. I found the chandrayaan 3 Blog it is isro.gov.in/chandrayaan3.html. I'm very curious to see what they have discovered. All I know right now is that the rover has left the lander and is moving on the moon's south pole.
