Re: Chandrayan-2 Mission
We still have no actual data shared after the signal loss. ISRO only said it has identified, which I assume is the orbiter shot, and we know it is still in one piece. NASA (per that article) says they will share both before and after pics...if both pics remains same with some markers, then there is ...

It is okay.. Let's only discuss about those 1% genuine nationalistic and their success. Rest 99% are horror anyway, and goes OT quite often unless it is all about feedbacks for handling failures.

I am trying to first rule out the case earlier reported in ToILet. "Too much Thrust"!!..
if we have our navs and controls pucca, then too much thrust can't be on the ground is my best assumption

Re: Chandrayan-2 Mission
If the thrusters were too powerful, then it can't be our control system not fast enough to control the navigations. It can't be just the thrusters. [assume: 1/6th gravity means it requires faster controls]

The small thrusters are 25 N ones should be enough for the 1/6th place. no? the weight of Vikram should be that much less. But then, we are assuming everything is intact per reports [no visuals we have seen yet]. --- another stupid question on pattern matching.. was this IR or pure visual range pat...

Re: Chandrayan-2 Mission
100 m/ sec 2.1km to go.. fast braking period.. nothing heard. That is pretty fast to land w/ balloons(if) and cushions. I thought 59.8 m/sec. But it is very fast. Even if it is free fall from there the terminal velocity at impact would be like sqrt ( 2100*2*1.62 + 59.8**2) = 102m/sec or 360km/hr. O...

Re: Chandrayan-2 Mission
1. did we really lose signal at a low altitude [assuming there is a delta latency between vikram and byalaru receivers, and the received altitude is not an estimate]. 2. if not, then loss of signal could be crash landing.
