Jason-3 Launches to Monitor Global Sea Level Rise

A+ A

Baku, January 18 AZERTAC

Jason-3, a U.S.-European oceanography satellite mission with NASA participation that will continue a nearly quarter-century record of tracking global sea level rise, lifted off from Vandenberg Air Force Base in California Sunday at 10:42 a.m. PST (1:42 p.m. EST) aboard a SpaceX Falcon 9 rocket.

Jason-3 is an international mission led by the National Oceanic and Atmospheric Administration (NOAA) in partnership with NASA, the French space agency CNES, and the European Organisation for the Exploitation of Meteorological Satellites.

The mission will improve weather, climate and ocean forecasts, including helping NOAA's National Weather Service and other global weather and environmental forecast agencies more accurately forecast the strength of tropical cyclones.

Jason-3 will begin full science operations after a six-month checkout phase, joining Jason-2, which launched in 2008. From low-Earth orbit, Jason-3 will precisely measure the height of 95 percent of the world's ice-free ocean every 10 days.

Coordinating orbits and combining measurements from Jason-2 and Jason-3 should allow even more frequent coverage of the global ocean. Together, the two spacecraft will double global data coverage. This tandem mission will improve our knowledge of tides in coastal and shallow seas and internal tides in the open ocean, while improving our understanding of ocean currents and eddies.

CNES provided the Jason-3 spacecraft bus. NASA and CNES are jointly providing the primary payload instruments. NASA's Launch Services Program at the Kennedy Space Center in Florida is responsible for launch management and countdown operations for the SpaceX Falcon 9 rocket. JPL manages the mission for NASA's Science Mission Directorate, Washington.
