Actually it was NASA built instrument that did the discovery but it doesn't really matter to me. Science is science, irrespective of the countries/parties involved.
Chopraji, You are right. Almost all space missions today, even those of USA are made of international teams. Science has no boundary, nor should it.
However, the title appropriately said "..helped discover.." and not "..discovered..".
This is India's first lunar mission. I know that it was not a complete success (we lost contact with the mission couple of weeks ago..), but it wasn't a failure either.
This mission, which costed a paltry $76M was able to be part of a historical discovery. So, it is appropriate to acknowledge the "Third World Country" which built it.
Why wouldn't they? They have not much to loose but the instrument. Lunar missions are not scheduled daily and if they are, it is a good idea to send your instruments with it.
