Jason 2 satellite will record role of oceans in climate change Jason 2, a French-U.S. satellite that will provide the most accurate monitoring ever of rising sea levels and track the effects of climate change, was launched into orbit from Vandenberg Air Force Base, California, on Friday. The liquid-oxygen-fuelled rocket sent an explosive arc of light into the night sky, some 256 km northwest of Los Angeles, as it launched the satellite on a three-year journey to track virtually the entire oceanic surface of Earth and extend the record of sea-level study from space to two decades.
