If anything they seem to have overcorrected for this. This landing path stopped with a near hover at around 800m, then a prolonged hover at 150m while the lander scoped the situation, then an extremely slow descent that allowed for corrections the whole way down. Very impressive.
Also incredibly inefficient.

Not considering such a basic error condition seems like a gross omission. This can't even come from the software engineering, but must be some kind of managerial failure (e.g. we're short on time, but have to report great progress to my boss, so skip this scenario).
Writing code for something that flies into space is not nearly as easy as you think it is. Perhaps the next time you write a comment you could first develop the software which you're complaining about first. I'm sure it would be a trivial task for someone of your stature :)
Or, are you saying that it's expected that the mission did not count with this scenario, and that future missions don't need to account for that either?

#133Scott Manly has a video on why he thinks the last one failed. It sounds like their landing software didn't have "oh crap, we're way off course, just land wherever". It only had the happy path of "fly to here and land", so when it switched to the landing phase it tried valiently (including flying upside down) to try to fly back to the landing zone, but the landing zone was much further than fuel supplies allowed. Hope…

Why such a long political speech and no views from onboard camera?
> Why such a long political speech ISRO is primary arm of the Department of Space which is headed by the Prime Minister. So in essence, the Prime Minister is the boss. It is not an independent federal agency like NASA.

#138One 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...
