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's Goddard Space Flight Center manages the NPP mission on behalf of the Earth Science Division of the Science Mission Directorate at NASA Headquarters, Washington.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
