French and U.S. researchers declared an 11-and-a-half-year project to survey the world’s oceans via space satellite officially over Wednesday, July 3. Jason-1, a space satellite that French and U.S. scientists had launched into space back in 2001 to track rising sea levels, was officially decommissioned following the reported failure of its last working transmitter.
It retires on a high note, though, according to NASA spokespersons, who said that Jason-1’s data transmissions made a significant contribution to efforts to forecast worldwide weather patterns and climate-change trends. Those transmissions had gone on for far longer than Jason-1’s engineers had ever expected: The satellite launched into space Dec. 7, 2001, with a mission projected to only last three to five years.
