SpaceX livestream much more mundane things with tens of thousands of viewers

10s of thousands. That has to be some kind of record.

Not at all! Although some of them will be people like me having it on the side monitor day dreaming while they write CRUD :)

Congrats to all of the team at ISRO. Assuming the software development for these is non trivial; Its interesting that with the last mission(per Scott Manly) was designed to always select a spot(or more precisely a trajectory) and try hit it. What made them make that decision? Was it like "lets be as precise as we can because we want to get to the spot X because X is special" and thus "Lets let the software always com…

Link to Manly's video?

That's not what my comment says. Personally I don't know how impressive or unimpressive the mission is since I am not interested in space exploration and I know almost nothing about it.

Though you've no interest in space exploration you qualify to pass judgement on how inflated a space exploration related post, how?

Because what I'm mentioning is a phenomenon that occurs in all Indian-related submissions regardless of content.

> No, he's just an elected representative of the people, a government servant. Yes. The elected leader is the boss of the executive branch of government. One doesn't negate the other.

PM is not the boss of the executive according to the constitution*. The fact that traditionally and more recently the President follows the whim of the PM does not negate the text that identifies the elected President as the head of the executive.

One of the most populous countries has become a strong contender in space exploration. Hopefully, it will inspire so many more Indians to push it further and elevate the humanity, just like USA and USSR once did. It's great.

Also here come the British news lamenting about how India is wasting money instead of focusing on their poor. Slumdog Millionaire mentality.

Also the British news when money is spent on the poor: "Scamming Scavs with 17 Kids Showered with Tax-Payer's Money".

Most British news outlets really are a scourge on our society.

NASA often gets the same treatment, particularly so during the Apollo program when they were getting a lot of money. It doesn't matter the country, a lot of people don't see the sense in spending a single pence on space. https://www.theguardian.com/science/2019/jul/14/apollo-11-ci...

One of my favorite quotes is, "When a wise man points at the moon the imbecile examines the finger." So pertinent, but also with so absurdly much imagery, symbolism, and metaphor packed into just a few words. But perhaps the most remarkable thing is that that quote's 2500 years old. Technology changes so much, but we largely seem to be the exact same people we were even thousands of years in the past.

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…

What typical engineering course covers the design of reliable systems which work mostly autonomously in environments with huge temperature variations, vacuum, inaccessibility for repair, significant radiation, mass constraints, sensor limitations etc?

Designing stuff for space involves a lot of challenges that typical engineering does not.

Plus, while the US and USSR may have done the necessary technical work, India doesn't get most of that knowledge and thus has to learn the lessons itself.

Is there a video somewhere from within the spacecraft at the exact moment of touchdown?

Not yet, closest option now is a computer animation synced with the confirmation of touchdown at minute 44 of the video. :(

At least there are these five images from two more cameras: https://twitter.com/isro/status/1694360664675127726
