The Soil Moisture and Ocean Salinity mission will provide global maps of soil moisture and ocean salinity. Soil moisture data are urgently required for hydrological studies and data on ocean salinity are vital for improving our undertanding of ocean circulation patterns. Together these data will contribute to furthering our knowledge of the Earths water cycle, and will improve climate, weather and extreme-event forecasting.
A significant milestone in the development of ESA’s Soil Moisture and Ocean Salinity (SMOS) mission was reached last week when the contract to build the payload was signed between ESA and EADS (European Aeronautic Defence and Space Company)-CASA from Spain.
The contract, worth 62 million euros, was signed in Madrid, Spain on 11 June 2004 at the premises of the CDTI (Centre for Development of Industrial Technology). EADS-CASA now heads an industrial consortium of more than 20 companies from all over Europe, and is committed to construct the innovative MIRAS (Microwave Imaging Radiometer using Aperture Synthesis) instrument that will form the core of the SMOS mission.
Scheduled for launch in early 2007, SMOS is the second Earth Explorer Opportunity mission to be implemented as part of ESA’s Living Planet Programme. The main aim of the mission is to further the development of climatological, meteorological and hydrological models by observing soil moisture over the Earth’s landmasses and sea-surface salinity over the oceans for a period of at least 3 years. At the signing ceremony, Prof. José Achache, ESA’s Director of Earth Observation Programmes, stated that, “SMOS will provide a major advancement in our ability to model and understand the global hydrological cycle.”

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
Scientists have succeeded in observing the first long-distance transfer of information in a magnetic group of materials known as antiferromagnets.
An international team of researchers has mapped Nemo's genome, providing the research community with an invaluable resource to decode the response of fish to...
Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.
Graphene – an ultrathin material consisting of a single layer of interlinked carbon atoms – is considered a promising candidate for the nanoelectronics of the...
