Aqua (EOS PM-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the precipitation, evaporation, and cycling of water. It is the second major component of the Earth Observing System (EOS) following on Terra (launched 1999) and followed by Aura (launched 2004).

The name " Aqua" comes from the Latin word for water. The satellite was launched from Vandenberg Air Force BaseVandenberg Air Force Base is a base with a spaceport, located in Santa Barbara County, California.

Aqua carries 6 instruments for studies of water on the earth's surface and in the atmosphereEarth's atmosphere is the layer of gases surrounding the planet Earth and retained by the Earth's gravity. It consists of nitrogen (78. 1% by volume) and oxygen (20. 9%), with small amounts of argon (0. 9%), carbon dioxide (variable, but around 0. 035%),:


The Aura spacecraft has a mass of about 1,750 kg. The body is 6.5 m long with the extended single solar panel about 15 m.
