Varun ,Please refer http://www.nasa.gov/topics/moonmars/features/moon2009092... and you will find the caption 'NASA instruments reveal water molecules on lunar surface'.The first line is "NASA scientists have discovered water molecules..' Immediately after termination of CY-1 was announced, it was reported in the press that the data collected by the instruments will be covered under IPR for some time.If you need I can search and locate the reference. Why the announcement water-on-moon was not made first by ISRO ? When will ISRO pat NASA?Again I repeat CY- 1 role is limited to being a carrier.

Bhushan, it’s true that the M3 is a NASA instrument, but remember that the satellite is India, as also the launcher. NASA got a free ride on CY, the agreement being that there would be sharing of knowledge. As for the discovery itself, NASA did say that the Indian scientists were involved.

The article under Chandrayaan(CY) is not factually correct.In 1994,Clementine probe(US),through bistatic radar experiment detected echo patterns which could come from water ice. The result has been published in Science,v274,p1495,1996.A number of experiments have been conducted afterwards,mainly by NASA/US.Coming to CY,almost the same radar experiment (employing 2 radars ,1 on Cy and the other on US probe),called tandem experiment,was tried .But unfortunately due to the malfunctioning of gyro on CY , the experiment was not successful.M3 was built by US/NASA and they have the right over the data. CY was simply a carrier .This is the reason why the presence of lunar water was announced by NASA in their press conference.Also ,three papers were simultaneously published in Science from three probes,M3 included.Till the announcement of NASA ,no such discovery was made public from Indian side.

hope we have many more such achievements in 2010.
