The mission

ESA’s Soil Moisture and Ocean Salinity (SMOS) mission is dedicated to making global observations of soil moisture over land and salinity over oceans. By consistently mapping these two important components in the water cycle, SMOS is advancing our understanding of the exchange processes between Earth’s surface and atmosphere and is helping to improve weather and climate models.

The launch

Date: 2 November 2009
Site: Plesetsk Cosmodrome, Russia
Launcher: Rockot
