A remarkable ESA campaign in one of the remotest regions on Earth has been fundamental in ensuring that the SMOS mission is delivering reliable data to improve our understanding of Earth´s water cycle. The two-year campaign set out to answer a simple but important question: do the microwave signals of a particular wavelength emitted from the surface the Antarctic ice shelf towards the SMOS satellite change over time? For a satellite mission that maps variations in soil...

Members of the driving force behind ESA's SMOS mission have been awarded the prestigious Certificate of Recognition by the IEEE Geoscience and Remote Sensing Society for their leadership in developing the first synthetic aperture microwave radiometer in space and for the success of the mission. The Geoscience and Remote Sensing Society awards certificates of this kind only every two to three years, and only when a significant achievement is recognized by the society's Administrative...

Despite continued interference issues, Europe's SMOS satellite is transmitting valuable new data on the way water is cycled across the globe. The satellite was launched in November to track changes in the wetness of soils and the salinity of the oceans using a microwave antenna. The detailed maps will soon be released for the eyes of the scientific community. But there are still some issues as SMOS is blinded by radar networks and media links in some areas of the world. The radio frequency...

In less than four months since launch, the first calibrated images are being delivered by ESA's SMOS mission. These images of 'brightness temperature' translate into clear information on global variations of soil moisture and ocean salinity to advance our understanding of the water cycle. Launched on November 2, the Soil Moisture and Ocean Salinity (SMOS) mission is improving our understanding of Earth's water cycle by making global observations of soil moisture over land and salinity over...

This image is the first data sent to Earth by the MIRAS instrument on ESA's SMOS satellite, launched on November 2. It was acquired as part of the initial functional verification test since the instrument was switched on Tuesday. The image depicts non-calibrated brightness temperature values color coded from blue (low) to red (high). Although the image content cannot be interpreted at this time, it proves that the instrument is in good shape and the data reception and processing chain...

The MIRAS instrument on ESA's SMOS satellite, launched earlier this month, has been switched on and is operating normally. MIRAS will map soil moisture and ocean salinity to improve our understanding of the role these two key variables play in regulating Earth's water cycle. "Following the switch-on, MIRAS is working beautifully well with all key subsystems, including all of the receivers, the optical fibers and the correlator unit, in perfect functioning condition," said ESA's Manuel...

Following the launch of ESA's SMOS satellite on 2 November, the French space agency CNES, which is responsible for operating the satellite, has confirmed that the instrument's three antenna arms have deployed as planned, and that the instrument is in good health. During launch and the first few orbits around Earth, the Soil Moisture and Ocean Salinity (SMOS) instrument's antenna arms remained safely folded up. Today, these three arms folded-out and now form a large three-pointed star shape....

Following word from Eurockot that launch of the Earth Explorer SMOS satellite can take place between July and October this year, ESA, CNES and the prime contractor Thales Alenia Space are now making detailed preparations for the last crucial steps before ESA's water mission is placed in orbit. The Soil Moisture and Ocean Salinity (SMOS) satellite has been in storage at Thales Alenia Space's facilities in Cannes, France since May last year awaiting for a third stage of the Rockot launcher to...
