Status: Current, Extended Mission
Mission Category: Earth Observing System (EOS), A-Train
Launch Date: May 4, 2002
Launch Location: Vandenberg Air Force Base, CA
Designed Life: May 4, 2008

Aqua is a major international Earth Science satellite mission centered at NASA. Launched on May 4, 2002, the satellite has six differrent Earth-observing instruments on board and is named for the large amount of information it collects about water in the Earth system. Aqua gathers this information from its stream of approximately 89 Gigabytes of data a day. The water variables being measured include almost all elements of the water cycle and involve water in its liquid, solid, and vapor forms. Additional variables being measured include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures.
