Chandrayaan failure: What went wrong?

A day after it lost radio contact with the Chandrayaan-1, the Indian Space Research Organisation (ISRO) has formally called off the moon mission.

So, what could have been the possible reasons?

* A possible failure in the power system led to a glitch in the control system
* The spacecraft
lost orientation and could not point its solar panel towards the Sun
* As a consequence the onboard battery got drained, which led to loss of contact with spacecraft
* The battery could not be recharged as the spacecraft lost orientation

Mission 'terminated', all over for the Chandrayaan-1. Now, the Chandrayaan will orbit the moon as space debris and may be crash onto the moon surface in three to four years.

But enough data has been gathered to keep the scientific team busy for the next two to three years. First scientific papers are expected to be published in next few weeks.
