Scott Manly has a video on why he thinks the last one failed. It sounds like their landing software didn't have "oh crap, we're way off course, just land wherever". It only had the happy path of "fly to here and land", so when it switched to the landing phase it tried valiently (including flying upside down) to try to fly back to the landing zone, but the landing zone was much further than fuel supplies allowed. Hope…

So in Scott's words, a "fly safe" subroutine?

Not asking rhetorically but why is this a big deal? Is it because it's going to the south pole? What are some other benefits to be gained from this?

Mission to unexplored south pole of the moon and investigating the presence of surface water at the bottom of craters that don't receive sunlight.

Simultaneously capability development and demonstration for ISRO

Am I mistaken or do they have an onboard view in the command center, but are not showing us?

They are showing it sometimes, with a camera pointed at that screen - the one to the left of the big numbers with velocities. There's also a simulated view that shows the surface (the second big screen from the left).

Currently in a live server with others watching and it's a lot of fun. I happen to know many people working in the space industry, and a lot of great engineers come from India. Very happy and excited for India and its people. Goodluck!

edit: lets goo!!!

Two points I'm aware of: 1. No one has managed to make a landing on the moon's South Pole yet. 2. Since the South Pole doesn't get any sunlight at all, it's believed that there's a possibility of discovering ice/water there.

* bottoms of craters on the South Pole.

Some places there get eternal sunlight instead: https://en.wikipedia.org/wiki/Peak_of_eternal_light
