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?

I'd be curious if it's at all interesting from a technical perspective. It was impressive in the 60s and 70s because a lot of new things needed to be discovered and understood to make it happen. But now a days.. are there really technical aspects that would not be covered in a typical engineering course? I get it's very expensive and hence difficult to pull off - but this makes it comes off as mostly nationalism and…

A lot of poor people were genuinely happy and inspired today.

Sorry to say but no contrarian thought in your comment.

Earlier quoted context omitted.

I cracked up at the little flag waving by who I assume was the prime minister/president. The duality is interesting serious Indian scientists doing great work and a politician on the screen for no good reason. Here’s to the tribe of scientist prevailing and taking the country forward, prob true everywhere now that I think of it.

> The duality is interesting serious Indian scientists doing great work and a politician on the screen for no good reason One can say the same about President Nixon talking to the Astronauts who landed on the Moon. At least here ISRO comes directly under the Prime Minister of India while NASA does not come under the President of USA.

Ah I see. Did not know that.

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…

Also did they use image processing to guide the landing this time? American and Chinese probes seems to use it to do the final phase of soft landing.

They have to, don't they? There's no other way.

This is a big achievement for India. Not just in space exploration point of view but the side effects of such projects are more interesting. Dozens of major private companies focused on making this success making various spare parts including steel cranes by Tata steel, special alloys of Mishra Dhatu Nigam (The Alloy Company), wings by L&T Aero etc. etc. I know some people here and they were so proud and focused on "…
