What is SMOS?
ESA's Soil Moisture Ocean Salinity (SMOS) Earth Explorer mission is a radio telescope in orbit, but pointing back to Earth not space.
Its Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) radiometer picks up faint microwave emissions from Earth's surface to map levels of soil moisture, sea surface salinity, sea ice thickness and others geophysical variable such as wind speed over ocean and freeze / thaw soil state.

Even just within the last couple of months, Cyclones Fani, Idai and Kenneth have brought devastation to millions. With the frequency and severity of extreme weather like this expected to increase against the backdrop of climate change, it is more important than ever to forecast and track events accurately. And, an ESA satellite is helping with the task in hand.

With recent stories in the news about the devastation brought by hurricanes and typhoons to the US and Asia, we are reminded of how important it is to predict the paths of these mighty storms and also learn more about how they develop. Many satellites have eyes on storms, but ESA's SMOS mission can offer an entirely new perspective.

Feeding a growing global population is a major concern, but efforts to grow more food will place an added burden on precious supplies of freshwater. New research shows how measurements of soil moisture from space could be used to understand how much water is used for agriculture and potentially help farmers manage consumption.
