Final instruments on NASA climate/weather satellite integratedJuly 23, 2010GREENBELT, Md. - The last of five instruments slated to fly on the upcoming NPOESS Preparatory Project (NPP) climate and weather satellite have been successfully integrated, according to NASA officials. The polar-orbiting satellite is scheduled to launch in late 2011. The NPP satellite was a pre-cursor mission to the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that has recently been restructured. The last instrument, Cross-track Infrared Sounder (CrIS), is an advanced atmospheric sensor, built by ITT Corporation, Fort Wayne, Ind. Ball Aerospace & Technologies Corp., Boulder, Colo., built the NPP spacecraft and is performing the integration and checkout of the NPP satellite. The CrIS mechanical, electrical and performance testing was successfully completed and the NPP Satellite team is now working to finish the satellite Pre-Environmental Test baseline performance phase. The Environmental Test flow, which includes Dynamics, Electromagnetic Compatibility, and Thermal testing, is scheduled to begin this October. The five-instrument suite will collect and distribute remotely sensed land, ocean, and atmospheric data to the meteorological and global climate change communities. It will provide atmospheric and sea surface temperatures, humidity sounding, land and ocean biological productivity, cloud and aerosol properties and total/profile ozone measurements. Data produced by the CrIS instrument combined with data from the Advanced Technology Microwave Sounder, another NPP instrument, will provide global atmospheric temperature, moisture and pressure profiles from space. The other three instruments include: the Visible/Infrared Imager/Radiometer Suite, which will collect information about atmospheric clouds, the earth radiation budget, clear-air land/water surfaces, sea surface temperature, ocean color, and produces low light visible imagery; the Ozone Mapping and Profiler Suite, which will monitor ozone and continue the daily global data produced by the current ozone monitoring systems, but with higher fidelity and the Cloud and Earth Radiant Energy System that will measure the Earth's radiant energy balance and help researchers to develop improved weather forecasts and climate model predictions. The NPP mission is a NASA-managed project to provide continuity with NASA's Earth Observing System measurements and to provide risk reduction for the National Polar-orbiting Operational Environmental Satellite System (NPOESS) managed by the NPOESS Integrated Program Office, a tri-agency program made up of NASA, NOAA and the U.S. Department of Defense. However in 2010, due to cost overruns and delays, a task force led by the President's Office of Science and Technology Policy recommended against continuing NPOESS. NASA/Goddard Space Flight Center |

ESA and EADS-CASA sign contract to build instrument for the SMOS mission 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.
