Is it considered "nationalistic flamewar" when people comment that maybe certain countries shouldn't even try to explore space? Just asking.
Yes. The phrase "certain countries shouldn't even try" is a pretty big clue.

Perspectives on evolution vs. devolution? But agreed, we are digressing.
It’s a bit of a false dichotomy, really. It isn’t as if the US is behind on accessing the moon or space in general. Nothing more than distracting partisan virtue signaling.
I was commenting in the context of the original remark. fwiw, personally I'd say the emperors are wearing no clothes on either side of the US polarized partisan divide, but then again I don't think the rest of the world is far behind and catching up fast in the race to the 'post truth' society.

#173Here's [1] a data graph of the Doppler curve from Dwingeloo Radio Telescope (based in Netherlands) showing the exact moment the probe crashed into the surface of the moon. https://twitter.com/cgbassa/status/1170072672266592256
I am confused, the contact with ISRO was lost at 2.1 km height (as per ISRO's last night statement). So, not at 0 km height (crash) ? Edit: I meant contact with ISRO..
This is all speculation but it could be buffering or it was tumbling so quickly that antenna switching couldn’t keep up or worst case, a RUD

#174Just a half serious question. Why can’t we just descend these landers on the moon with a steel cable slowly?

> Do you know how many different empires, rulers, internal wars and government systems China and India have gone through in 2000 years, and how many "races" and "cultures" they have? Yes. Still more homogeneous and stable than most other empires...
Oh you mean like that time when the Mongol conquered and ruled china for like, 100+ years, ushering in the largest case of minority rule the world had ever seen to that point. https://en.m.wikipedia.org/wiki/Yuan_dynasty
I mean like that time when this was just an episode in millennia of history...
I also mean like that time when the eventual demise of most empires and huge nations was my point, which China and India managed to avoid, and not China and India themselves (which are totally orthogonal to the point I was making, and in fact an exception to the rule I posited)

And there has been no terrorism in Kashmir since decades, right?
The existence of terrorism gives you the right to invade?
Invade? Please for god sake read about India and Kashmir first before you reveal your ignorance here. Kashmir has a complex history. It was ALWAYS part of India but governed under a certain constitutional provision. The Indian Govt just revoked that provision.

I recommend reading about the Three Kingdoms as a starting point. As for India, look up Pakistan.
The idea that I wouldn't already know of those things, or that they somehow invalidate what I wrote, I find fascinating...
Meanwhile, I've mentioned Pakistan already in another answer many hours ago...

In terms of orbital mechanics the polar orbit around the moon isn't significantly more complicated than an equatorial one. A small midcourse correction after entering a flight path towards the moon is all that's needed to ensure capture into orbit around the poles (and a capture burn), without the need for a plane change (note that this is also based on experience from KSP).
I see what you mean, though I'm not sure of all the details, you might want to get into an equatorial orbit (there is an orbiter, though I'm not sure about its orbit) just because the error margin is smaller (?) or for some other reason. (But then of course the moon is neither too far nor too big so I might just be barking at the wrong tree here)
As far as I can tell, the lunar orbiter itself is in a polar orbit, so it would make sense that it entered orbit as such. In terms of complexity the main part of the journey to the moon is the midcourse correction and ensuring that the engines fire at the correct time, in the correct direction, and for a certain duration. Depending on the engines used - ie. engines that can be used mutliple times - more than one midcourse adjustement may have been possible. It seems that all of these things worked out fine, since the Chandrayaan-2 orbiter has been there in a polar orbit since 20th of August [0]. The lander seperated since then, and the loss of contact a few seconds before the expected landing time implies that the lander reached the surface with a velocity higher than expected.

#179This is a great thing for the people of India - I mean, hopefully.
The science we expel is a reflection of the cultures that created it. In space, everyone has had failures. And I hope this failure offers reflection and improvement and that they can grow from it.
But even still, this is otherwise part of a narrative change for the people of india, and something "so simple" can have a huge impact on future generations and what people tell themselves on an individual level.

And I'm commenting in response to your remark on "devolution." There is none, insofar as I can see. It's a pointless partisan jab not rooted in reality.
