Blobrana · L

Marking another significant step in the GMES initiative, ESA and Thales Alenia Space recently signed a contract worth 270 million to build the second Sentinel-1 and Sentinel-3 satellites.
Led by the European Commission in partnership with ESA, the Global Monitoring for Environment and Security (GMES) programme will provide a unique tool to monitor the environment. This initiative will fulfil policy-makers' growing needs to access accurate and timely information to manage the environment better, understand and mitigate the effects of climate change, and ensure civil security.

ESA Tests Mini Gyro Sensor For Sentinel 3
The European Space Agency (ESA) is testing a miniature solid-state gyro sensor that it says will be the smallest ever flown in space.
The sugar cube-sized gyro uses microelectromechanical systems (MEMS), a technology already widely used in the automobile industry that allows moving parts or sensors to be incorporated on a single silicon chip, saving space and weight and improving reliability.
The first application of the sensor will be the Sentinel 3 ocean, ice and land vegetation mission, to be launched in 2013 for Europe's Global Monitoring for Environment and Security network.
