Jason-1 satellite celebrates 10 years of observation.

On December 7, 2001, Jason-1 was launched into orbit by Cnes and Nasa and soon after began to demonstrate an exceptional level of performance.  More than a breakthrough in ocean observation, Jason opened a new pathway for radar altimetry, nine years after its predecessor mission Topex-Poseidon.  Measuring ocean circulation and its variations; measuring of the elevation of mean sea level reflecting the changes in temperature-salinity and the thawing of ice; the study of tides; are just a few of the many fundamental contributions that Jason-1 has made in the past 10 years (Source JPL).
