India's Moon Exploration Program

[sorcerer]

ISRO chief is saying, orbiter now has a life span of 7 years, because of extra fuel.

so next Chandrayaan mission, less weight to carry?

What was the weight of the orbiter?

2379 kg
The Chandrayaan 2 orbiter is a box-shaped craft with an orbital mass of 2379 kg and solar arrays capable of generating 1000 W power.

there was a fly-by earlier today of our orbiter above the probable landing site. Curious no updates yet.

Wish Vikram carried an on-board camera, then we could have got coverage like this -

Vikram had many cameras... look at this below video to have idea how much tech was involved hence Vikram was automatic and independent we couldn't establish the video once signal was lost

Not the first time we have suffred a Communication loss..during a critical phase where the scope for some contingency intervention was very narrow or null.
Suffered it during the CARTOSAT launch event..which was VERY VERY Crucial satellite for India.
and now on Chandrayaan 2

Didn't we successfully landed on chandrayaan 1 ?
So why was it a problem this time, i am just curious.

The objective of Chandrayaan-1 was to find water on Moon. At that time, ISRO did not have heavy lift capacity to send a rover on Moon. So ISRO designed a technique called Moon Impact Probe. First phase of this mission was to put an orbiter (Chandrayaan-1) in the lunar orbit. Once the first phase was complete, the second phase began which consisted of a rocket slamming into Moon with a high velocity. The impact released debris high up on the lunar surface. After that the third phase began: Chandrayaan-1 started to descend towards the lunar surface. As it approached the lunar surface, the sophisticated instruments onboard gathered data from the debris and transmitted them back to Earth before it too intentionally crashed into the lunar surface. The data was analyzed and the result of the analysis indicated that there was water on Moon.

Chandrayaan-2 is sort of followup and more to Charndrayaan-1.

We should have our own Indian deep space communication network... rather than rely on the COMPETITORS in space race for resources and their COMs

We have it. Not as big as American. Having more antennas around globe is geographical and not technological limitation.

Since israel and india both failed in soft landing, i think we can collaborrate on it.

Also i am curious to know if the 3 nations who achieved this, did it in first attempt ?

That sounds quiet suspicious. Any chance of foul play here ?

I thought we had one in Bangalore? https://en.m.wikipedia.org/wiki/Indian_Deep_Space_Network

I think we have to rely on other networks when the moon is not over the horizon in India.

 

[ataru09]

We haven't sent any satellite that far. May be when we do we would build one.

We sent one to mars!!!

Which satellite bus is it based on?

I-1K or I-2K?

Not sure...but we do know many nations dont want us to succeed in the most ECONOMICAL part of the space race.
and we do know that many nations had done such to each other before to sabotage the rivals esteemed space missions.

Hope its not the same with the chandrayaan 2.

errrmm....
Thats greek to me .
sorry!

We can only communicate with IDSN when the spacecraft is directly facing this part of the earth.

NASA is the only space agency which has 360• coverage.

Thats my point...we are looking to venture into venus and other planets...even having own space station of sort...so better to start having a deep space communication grid in place..right now itself. These things does take some time to establish itself I guess.

ISRO has its own deep space network. But it has antennas only located in Bangalore.. unlike the US which has such antennas located all over the world..

Just came across this tweet but I cannot claim the veracity of this handle.

Yes, and images have already been downloaded. Principal scientific advisor to PM tweeted that he has seen the images, and are very crisp.

 

[afako]

Dunno but having hopes that it can be revived. Miracles still happen.
