US: Jason-1, a satellite that for more than a decade precisely tracked rising sea levels across a vast sweep of ocean and helped forecasters make better weather and climate predictions, has ended its useful life after circling the globe more than 53,500 times, NASA said.
The joint US and French satellite was decommissioned this week after its last remaining transmitter failed, according to a NASA statement.
Launched on December 7, 2001, Jason-1 was designed to have a lifespan of three to five years but it lasted for 11 ½ years.
Every 10 days, its instruments scanned the ocean surface, mapping sea level, wind speed and wave height for more than 95 percent of the planet”s ice-free ocean area. It was one of three oceanographic satellites that contributed to a 20-year record of sea-level changes, NASA said.
