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. :(

#403Especially impressive when taken into account that ISRO couldn't achieve the soft-landing with Chandrayaan-2 four years ago. One of the big things they changed with this lander compared to Chandrayaan-2 was to increase the landing zone from 500mx500m to 4000mx4000m and adding more sensors and cameras to help the computer find a good landing site. For those who didn't watch live, there was another hover phase (0 m/s d…
Very well explained

While I appreciate your engagement with the topic, I must point out that the notion that we can 'tackle both' is a dangerously simplistic perspective. The resources—both financial and intellectual—that are poured into space exploration are not infinite and come at the expense of urgent, life-saving initiatives here on Earth. To say it's 'widely known' only underscores the normalization of this skewed prioritization. We're not living in a utopia where all problems can be solved simultaneously; we're in a world where choices have consequences. The urgency of our Earth-bound crises doesn't afford us the luxury of romanticizing space exploration as if it's without trade-offs.

#406Not 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?
We get to see more images of the Moon's surface. In a previously unexplored region.
How is that not a big deal?

#407Earlier quoted context omitted.
> seems like such a gross omission. Almost all space mission code only ever has the so-called 'happy path'. We rely on extremely tight mechanical and aerospace engineering tolerances to achieve that happy path. The Hubble Space Telescope's primary mirror grinding was off by a matter of micrometres, and resulted in blurry images. Consider all the Mars rovers. Imagine some wind gust threw the descending module off cour…
That can't still be the case these days, can it? Extremely tight mechanical and engineering tolerances are very expensive compared with merely 'very very' tight tolerances, and I'd imagine the difference between the two can be bridged with more intelligent software in place of "gyroscope + clock + maybe PID loop"?
The classic hardware engineering response of "we'll just fix it in software". Turns out fixing things in software is even more expensive because it's just so easy to make changes that a combinatoric number of changes sneak in.

#408Please please let this bring on a second space race! I want humans on Mars during my lifetime!
Yeah! Me too!

> The infamous quote "One small step for man, one giant leap for mankind." What makes the quote in famous rather than just famous?
Unless you were being sarcastic, it's because people don't know what the word infamous means and think it means "extremely famous".
No sarcasm, just wondering. Armstrong could have been cancelled or something. I might have missed the Two Minutes Hate [0] when he or lunar exploitation was on.
Re: Chandrayaan-3 Soft-landing [video]
#410Congrats 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?
Probably this one: https://youtu.be/2ngVl6iO94c
