Can someone help me understand this Wikipedia article section: https://en.wikipedia.org/wiki/Chandrayaan_programme#List_of_... Check the row for Chandrayaan-2. Why does it say Unsuccessful landing but main mission success and extended missing ongoing? What exactly are main mission and extended mission and how can they succeed or be ongoing when the landing has been unsuccessful?

Chandrayaan 2 had 3 payloads. The lander crashed along with rover. But the orbiter is still functioning. It has 8 scientific instruments on board for various observations of lunar surface.

Earlier quoted context omitted.

A lot of things in the world trade inefficiencies for safety.

I was surprised they had the propulsion budget for it.

Not only was the Chandrayaan 3 budget lesser than that of Chandrayaan 2, as a meme doing the rounds point out, it was lesser than the budgets of some Hollywood blockbusters like Interstellar. So yeah, safe to say they could have had the budget for more if necessary.

One of the clocks is labeled "IST," which I assume means India Standard Time. Another clocks are labeled "GHY," "HAW," and "BIK." What do they indicate?

Goonhilly, Hawaii, but I can't figure out BIK. They're NASA and ESA tracking stations: https://www.eoportal.org/other-space-activities/estrack , https://www.indiatoday.in/science/chandrayaan-3/story/how-is...

I'm not very familiar with this source [0], but it states "ESA was providing support to the Chandrayaan-3 mission from three of its ground stations located in Kourou (French Guiana), Goonhilly (United Kingdom), and New Norcia (Western Australia)." Although BIK doesn't obviously map to any of those.

Firstly - congratulations to the whole team on this achievement I'm also curious - Why the south pole of the moon? does it have an added significance vs other locations on the moon? - Is a landing on the south pole more difficult to achieve? Seems so according to this article: https://www.reuters.com/science/why-are-space-agencies-racin...

Possible water which would be a giant resource for a permanent presence.

I get the point that the US already put people on the moon… but how can you possibly make the leap that there can be no scientific value to additional unmanned laboratories and instruments landing on the moon? Especially since this represents increasing the number of countries who can contribute to this scientific endeavor? If the US elects a president who is not interested in lunar science or has economic problems,…

> I get the point that the US already put people on the moon

I didn't mention the US and I'm not from the US (I'm French). Humanity landed on the moon. Over 50 years ago.

If a country today built a 1969 computer I wouldn't marvel at the achievement.

And yes, sure, there are probably many instruments on board. But you can tell from the video -- and all the excitement here as well -- that this is mainly political and politically motivated.

> If the US elects a president who is not interested in lunar science or has economic problems, then the whole world must wait for the US to decide to resume lunar missions?

Or maybe do something else with our limited time and ressources than trying again to analyze the lunar surface and pretend it will be useful? While planting friggin' flags all over the place?

> It is of special interest to scientists because of the occurrence of water ice in permanently shadowed areas around it. The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior. Such craters are cold traps that contain a fossil record of hydrogen, water ice, and other volatiles dating from the early Solar System

South pole is unexplored and no one has ever landed there, manned or unmanned. Exploring the unexplored isn't science?
