There's a flurry on new info. In particular the variance of surface temperature at the lunar south pole, from 60 degree Celsius on the lunar surface, to -10 degree Celsius if you probe just 8cm below the surface https://nitter.net/pic/orig/media%2FF4hsyEQaEAAB-AS.png A whole seventy degree temperature difference over such a small height delta. There were a bunch of scientists trying to explain this on Indian news TV…

Honestly super happy for India for pulling this off. People don't seem to acknowledge the amount of science that's been coming out of India for a long time now and I hope this enlightens people a little on the fact that the country has a lot of strong intellect to share with the world.

Cannot this gradient be used for some sort of heat pump? Or is it more effective to just outright collect the photons with solar panels.

The gradient is there for the exact same reason that you your pump won't reach a lot of material and will just create a hot mini-island near you heat exchanger.

On that graph: isn't it conventional for the independent variable (in this case, depth) to be on the x-axis?

I do not think that is what the author intended - "You want your home country to do well but at the same time you are hyperaware of its numerous deficiencies."

I am aware of the deficiencies, but also very aware of the progress being made. There is no magic wand to wave to make people not be like people and change a vast, diverse population into something they are not.

> ISRO announced the rover’s LIBS results definitively confirm the presence of sulfur at the landing site. Additionally, preliminary scans detect traces of aluminum, iron, calcium, chromium, titanium, manganese, silicon, and oxygen in the soil. Further hydrogen detection efforts are underway. What about hydrogen? No hydrogen means no water where they're currently landed, right?

They certainly won't find water on a 60C surface.

So what you are saying is that the numerous deficiencies are *intrinsic* to India (and Indians) by extension and will never go away? Is is about their DNA (nature) or their culture (nurture)?

What is about "a vast, diverse population into something they are not"? Are you saying India can not be a middle-ish income country like China/Thailand/Malyasia etc. I would like to believe that wise choices by the electorate and good leaders and some luck can transform the country (or any country). Japan/South Korea/Thailand/Malaysia all did it. Some of those countries are vast, some diverse and some had less advantages than India.

If you believe in the opposite that then are you not giving into the ideas in the "Clash of Civilizations" or worse "Genetics as IQ" crowd?
