If your words come true I will send you a pot of Rasmalai sweets.
Send sonpapdi. Rasmalai pohochte pohochte Chandrayaan 2 ban jani hai sir, dekh hi payega launda kha nahi payega
As I told yesterday, if it is Intact, it is a soft landing. It may have toppled over but that is a different thing.It intact !! YAY !!
If intact then it’s not the landing that damaged the communication system. That went down several minutes before touch down.
If intact it does not mean it's a successful landing. The moon's soil is like a sponge + very little gravity and if anything falls on it even at 80 or 100kms per hour the chances of it getting damaged is high but it will be an elastic collision, it will bounce and due to that the physical deformation will be little.
A craft covers 3.84 lakh kilometers from earth and arrives at its destination just 500m away. This is some navigation accuracy. Let Pakistanis know that this is what we can do and had it not been for the last minute problems, the error could have been zero. These Pakistanis can't fire a Hatf rocked with such accuracy
We all know if we establish communication with vikram lander, sweet will be the last thing in anyone's mind. Some will rush for beers and some for whiskey.
I don't know why we even consider bringing pataal-lok into discussion. They are not even in the picture just trying to take some publicity that they also have some space mission, oh la la cheering girls in the stadium that's their aukaad. We should compete with the Chinese. Ignore the pataalis.
If ISRO can re-establish communication with lander Vikram, then it will be a Cinderella moment for us. ISRO off late had a remarkable string of success with big ticket programs. Chandrayaan 1, Mars orbiter mission, launching a record 108 satellites , success came all to easily, no doubt it was because of their through diligence, technical competence and skillls developed over the decades, for ISRO and the law of averages was bound to catch up one of these days. If this means that ISRO will be perked up to ensure the manned space flight missions will be incident free and make it a resounding success, then so be it.
Let's think logically
comms stopped while the lander was still descending
Due to inappropriate functioning of the thrusters the lander was most probably subjected to high G forces and related stress and strain while still in flight when the comms snapped.
this means some components inside lander were subjected to higher than rated g forces.
So as i previously alluded lander must have landed , but there was comms failure due to possible malfunction of some comms equipment . Higher that expected G forces might have induced anomalous behaviour in the comms component like displaced linkages or unintended transient voltage transfer / voltage spike causing shut down. unfortunately I have no understanding of the working of the same in space systems. So not 100% sure.but Similar power failures happened with isro satellites power bus.
The onboard TX/RX system requires the onboard data processing package to process data and format it for transmission over the same and vice versa after receiving the data. TX/RX system is working but the backend system which processes the data to be sent or be received seems not to be working at the moment.
Communication link is open but no data is being sent or received at the landers end atleast for now.
The power supply from battery if bypassed for the secondary power source the solar panels , then there exists a possibility that the anomalous condition with the effected components of the comms system might get resolved and the system might reboot.
Eg in a normal oscilloscope if it is subjected to out of range voltage beyond instrumented range , the output readings flatlines and shuts down to recover and then reboots if the surge voltage is no longer present.
So same recovery can happen with the landers malfunctioning components provided the anomalous cause ceases to exist .

If the mars mission is any indication the damn orbiter will still be giving data 20 years from now
ISRO has said 7 years instead of expected 1 year for orbiter, so using MOM as an example it would possibly end up working for 50 years
