| Neither. By all accounts, it has been a mixed performance. Also, a definitive answer is not easy to give - it is possibly as grey as the surface of the Moon. | Neither.

| This was an expensive scientific experiment with many objectives and conducted in full public glare. Most engineering goals have been fulfilled, but pious promises to deliver "good science" from the mission are still to be met. | This was an expensive scientific experiment with many objectives and conducted in full public glare.

| Certainly not, since the know-how and technologies to go to the Moon are just not available for the asking. Each nation has to learn on its own. India experimented and did that with complete success. | Certainly not, since the know-how and technologies to go to the Moon are just not available for the asking.

| Possibly. The answer may emerge in the findings of the "failure analysis committee" that Isro has put in place after this debacle. | Possibly. The answer may emerge in the findings of the "failure analysis committee" that Isro has put in place after this debacle. |

| A fuel leak from the rocket almost aborted its lift-off. Within days of reaching the Moon a power system failed, and a back-up system had to be activated. | A fuel leak from the rocket almost aborted its lift-off.

| Soon, the spacecraft started overheating due to the intense summer heat on the Moon. Isro scientists say it was deft mission management that saved it from a total burnout. | Soon, the spacecraft started overheating due to the intense summer heat on the Moon.

| Finally on 29 August 2009, the space agency lost all contact with Chandrayaan after a catastrophic failure - possibly in its power supply system. A day later the mission was "terminated", although Isro chief G Madhavan Nair declared it had been a "complete success". | Finally on 29 August 2009, the space agency lost all contact with Chandrayaan after a catastrophic failure - possibly in its power supply system.

| This was more than an experiment. It was also a brave global geo-political statement since the probe that crash landed on the Moon also permanently placed India's flag on the Moon. | This was more than an experiment.

| A little known fact is that India did not charge any money to fly these instruments 400,000km away: all got a free ride to the Moon, merely in exchange for sharing the scientific data. | A little known fact is that India did not charge any money to fly these instruments 400,000km away: all got a free ride to the Moon, merely in exchange for sharing the scientific data. |
