Oceanography satellite Jason-1 makes his final bow

The world superstar oceanography satellite, spacecraft, served for a total of 11.5 years. A joint project of NASA and the center of Centre National d "Etudes Spatiales (CNES), the satellite to study sea level Jason-1 was retired this week after losing their last remaining the satellite transmitter.

Launched in December 2001, initially with a planned service life of 3 to 5 years, Jason-1 has helped to create a huge database on the topography of the oceans for the 20-year period
which began to fill up the information in 1992, the satellite NASA / CNES Topex / Poseidon. Having performed more than 53,500 orbits around the planet, Jason-1 was accurate maps of sea level, wind speed and wave heights for more than 95% of the ice-free ocean surface, making their measurements every 10 days. This mission has allowed scientists to better understand ocean circulation, and track the rise of water levels in the seas, to more accurate weather forecasts.

Contact with the satellite Jason-1 was lost on June 21, and the decision to decommission was taken on July 1 after a number of unsuccessful attempts to re-establish communication controllers.
