Mapping Soil Moisture and Ocean Salinity to improve understanding of the Earth’s water cycle – By Mark Drinkwater, Head, Mission Science Division (European Space Agency)
The European Space Agency’s Earth Explorer series of research-driven satellite missions continues with the upcoming 2nd November launch of the Soil Moisture and Ocean Salinity (SMOS) mission. Known as ESA’s Water Mission, SMOS is the first satellite dedicated to providing global measurements of soil moisture and ocean salinity. The mission’s new technologies will extend key European capabilities in Earth Observation and help advance research towards improving our understanding of the global water cycle. Read more
Over the course of the last weeks, since the successful launch from Plesetsk, Russia on 17 March, teams of flight operations staff have been feverishly working to commission the GOCE satellite. GOCE was injected into orbit at an altitude of 283 km on 17 March. Since then, it has been freefalling at a rate of 150 to 200 m a day and will be allowed to continue to do so in a controlled manner until we enter the so-called “drag-free mode” of ion thruster operation – before starting the first science measurement operations phase.
I can happily report that the GOCE satellite was successfully launched from Plesetsk today and has been placed into the correct orbit by its Rockot launcher! At my time of writing, we have had contact with the satellite on two successive revolutions at the Kiruna and Svalbard ground stations, and now the launch teams take a well-deserved break. ESOC in Darmstadt is now controlling the satellite and will continue with the Early Operations Phase to establish the health of the satellite now we are safely “on orbit”.
Expected to reach its destiny today, GOCE, ESA’s mission
