NASA’s researchers designed the Aquarius/SAC-D spacecraft, a satellite which have to study the salt levels in Earth’s oceans. The Earth-observing Aquarius/SAC-D will measure the salt levels, or salinity, of the ocean surface, and the following interactions between ocean circulation, the water cycle and other drivers of the planet’s climate.With the help Aquarius/SAC-D every seven days researchers can recieve enough data of salinity of Earth’s oceans. These data will help understand how salinity changes over time and from one part of the ocean to another. Also Aquarius/SAC-D will collected data such as measurements of ocean surface winds, over the entire surface of the Earth.
Aquarius satellite have to launch June 9 atop a Delta 2 rocket from Vandenberg Air Force Base on the central coast of California.Researchers found that the satellite will work in orbit for at least three years.
