Astronaut photographs inspire next generation of scientists

30 December 2014

Students from Connetquot High School in Bohemia, New York, used astronaut imagery of Earth to compare impact craters on Earth with those on other planets. The images were provided through the Expedition Earth and Beyond (EEAB) program, which connects students in grades 5 and higher with pictures taken by astronauts aboard the International Space Station.

6th International Workshop on Microwave Filters

23 - 25 March 2015

Organisation: Centre National d'Etudes Spatiales (CNES) / European Space Agency (ESA)

Location: Toulouse, France

Workshop Overview:

This 6th co-organised CNES and ESA International Workshop on Microwave Filters addresses the complete development cycle of Microwave Filters, i.e. from filter synthesis to the manufacturing processes.

Filters and multiplexers are key building blocks in science, navigation, Earth observation and telecommunication applications. Satellite systems are in constant evolution to answer to new and changing needs in terms of throughput, coverage, flexibility, RF performances.

Science and Earth observation applications are mostly related to high/very high frequencies where topologies, manufacturing methods / accuracy and materials play a key role.
