Chandrayaan-2 : Updates

Failure is part of space exploration. We move on regardless. I still remember watching the Columbia disaster live on TV way back in 2003. My entire family watched it in complete horror. Point is, As ISRO moves further into space exploration and human space flight programs. We have to prepare ourselves as a country to accept failures and accept losses. Just like the way Soviets and the Americans did.

Ironically Pakistan Military is reduced to such a level that they have to stoop down to social media trolling and candle marches to fight an enemy . Its actually hilarious if you realize the ground situation.
We shouldn't bother about them. They are irrelevant. Even fawad Chaudhary was making fun of the failure- he claimed Pakistan will land a man on Mars in 2024. It might be true because they are committed to landing a terrorist in every corner of the Galaxy

Yes. And these might not even be the worst of our failures. When human spaceflight program starts there is a likelihood that at some point we will lose people. We need to be ready for sach eventualities too. We need to have a thick skin about this things.

That clown can't even get 1,2,3,4 straight. He wrote point # 1,2,4,4

Define Irony:

Pakistani generals who cant even insert 10 terrorist successfully in LoC these days are making fun of Lunar orbit insertion :ROFLMAO::ROFLMAO:
 
Let's assume lander crashed then what will be the velocity at which it crashed?

Using v=u+at and v=d/t and a=1.65m/s^2 (g of moon) I calculated velocity should be in range of 15-20 kmph (assuming freefall at 2km altitude)

I did this off the top of my head. Please correct me if your results differ.

I
Now how much damage can you expect ramming lander on surface at 15-20 kmph speed?

v^2= 2000x1.65

My bad. It's 57.44m/s or 206 kmph. Below pic shows vertical speed 59m/s or 216 kmph.

Braking system/ boosters failed to provide soft landing. Vikram then slammed on the moon and LOS.

It's like 1.5 ton Car ramming into wall at 200 kmph speed.

Aaj se aisa mazak mat karna bhai:cry:.

Polar landing on moon is not a piece of a cake. I had this feeling from day one that we might miss it this time.

We are not really far behind the chinese. We can still match them. Chinese have conducted two fly by mission to moon scanned the whole area twice, and made sure of the comm network works fine before going for the landing.

Our next moon landing should be to land and take off from there and bring back the sample.
 
I have a feeling this mission has been sabotaged. Anyone has any clue what this 'passive device' 'The laser reflector arrays from Nasa' is? the mission was carrying this payload from NASA. It seems to be a high precision location sensing device.

It seems the same device from NASA was also installed in Irsraeli spaceship which crashed earlier this year. I dont understand why any important mission will carry such stuff
 
Meanwhile These Disgusting Creatures called Pakistani s are celebrating as if they have won something

Most disgusting creatures on Earth

Not just them even some Indians or fake indians too..

Don't know why they indirectly hit at BJP by being sarcastic with ISRO.

Isro should be our pride.. Instead for some only politics is important.

Same with Doval s press release..

The thrusters to retard were still firing and on. so the final speed must have been very low. Please remember the communication was lost at 2.1kms from touchdown but at that time everything was working perfectly

I think deviation happened at 2.1 km altitude which is close to fine braking system /deceleration mark.

Communication worked till 1 km altitude that shows in my attached pic lander sent telemetry data. Before next set of data arrives as per refresh interval of software code, lander already crashed.

As per my understanding communication have no bearing on autonomous landing.

Read your picture correctly. You are misreading the information. The altitude shown is about 500m and the down range is 1.09Kms. Down range the range to the touch down point in x-axis read backwards from the point where the deorbiting started by harsh braking. Altitude is on the Y-axis.
