Bummer. I hope they figure out what went wrong, the worst kind of failue is one you learn nothing from.

I wonder if it's related to the problem aboard the craft discovered several months ago. But after all, the spacecraft was put into a more stable orbit. A loss of signal could mean a problem with the transmitter, a problem with the onboard computer... it could mean a lot of things.

I don't have if they have any scenarios in such sases. For example, sending a command to reboot the computer, or something like that.

I'm thinking you are right. Unless they knew something was about to go, this is really soon to through in the towel on a missing spacecraft.

Too soon? Maybe. But maybe not. They're talking about the worst. The probe is not transmitting data, it's not responding to commands.

We should remember that many few spacecraft recover after a total loss of signal. Examples? Probably SOHO. Yes, SOHO. But many other examples tell us that loss of signal means failure.

Ouch...that's a tough one.[/size] It was expected to finish off the remaining 5% observation operations again this October, wasn't it? But, perhaps, its new (safer???) orbit combined with the recent LRO link-up experiment may have pushed it too far. [size="2"]John

I'm guessing (hoping) that they got everything done with the joint radar mapping with LRO, and got all the data back from that?

It's disappointing, but nonetheless it is a partial success and according to ISRO the mission achieved most of its science goals. For India's very first planetary exploration mission, it's been pretty successful when you consider the many failures the USA and USSR had in their early days of space exploration.

The mission has also now created a layer of invaluable expertise in India for planning, building and operating planetary exploration missions. Forward with India's space programme! smile.gif




PS: It also wouldn't hurt if ISRO learn some better PR too! laugh.gif

If...IF...this is truly the end for Chandrayaan-1, it nevertheless was one hell of an impressive first planetary mission by ISRO and they should be extremely proud of this achievement.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
