Jason-1
Jason-1 was the joint NASA-CNES ocean-altimetry mission launched on December 7, 2001 to continue TOPEX/Poseidon's precision sea-surface-height record. Its radar altimeter, microwave radiometer and tracking systems measured ocean topography, wave height and surface wind conditions, supporting studies of circulation and rising sea level. The mission exceeded its planned lifetime and operated for more than eleven years. Loss of its remaining transmitter ended data return, and the spacecraft was passivated and decommissioned on July 1, 2013.
