This is true. Here's the Chandrayaan-1 (earlier lunar satellite) payload: http://en.wikipedia.org/wiki/Chandrayaan-1#Payload http://en.wikipedia.org/wiki/Chandrayaan-1#Payload It contained significant instruments from NASA and ESA. The instrument that discovered polar water was M3: http://www.jpl.nasa.gov/missions/details.php?id=5923 http://www.jpl.nasa.gov/missions/details.php?id=5923 I believe it was given a free ride by ISRO, but the instrument itself was paid for by NASA.
