SMOS, ESA's Soil Moisture and Ocean Salinity satellite, was launched on a Rokot rocket with a Breeze KM upper stage from Plesetsk on 02 November 2009 at 01:50 UT. The primary instrument for the 658 kg satellite is the L-band MIRAS (Microwave Imaging Radiometer using Aperture Synthesis) radiometer composed of a 69 element Y-shaped antenna array. The satellite will monitor sea surface salinity and soil moisture on a global scale. SMOS data will be used to build maps of salinity and moisture levels and contribute to global circulation models.
