Europe’s space Sentinels


Sentinel-1
 
Sentinel-1, the first Earth observation satellite to be built for Europe’s Global Monitoring for Environment and Security programme.


 
The Sentinel-2 mission will be able to monitor changing landscapes like this area by combining a large swath, frequent revisit and systematic acquisition of all land surfaces at high spatial resolution and with a large number of spectral bands. It is being developed by ESA for the European Global Monitoring for Environment and Security programme.

Sentinel-3 is being developed by ESA for the European Global Monitoring for Environment and Security programme. The mission’s main objective is to measure sea-surface topography using radar altimetry, sea- and land-surface temperature using an advanced visible/thermal radiometer and ocean- and land-surface colour using a visible spectrometer.

Sentinel-5 precursor
 
Sentinel-5 Precursor will be the first satellite dedicated to monitoring atmospheric chemistry for the Global Monitoring for Environment and Security (GMES) programme.
