See our seasons change from space

With the Copernicus Sentinel-3A satellite fully fledged and its data freely available, the task of monitoring and understanding our changing planet has been made that much easier. Seeing the effect spring has on our plant life is just one of its many uses.
Launched in February 2016 and carrying a suite of instruments, Sentinel-3 is the most complex of all the Sentinel missions.
As the workhorse mission for Europe's environmental monitoring Copernicus programme, it measures Earth's oceans, land, ice and atmosphere systematically so that large-scale global changes can be monitored and understood. While Sentinel-3 offers this 'big picture', it can also be used to monitor smaller-scale environmental issues such as urban heat islands.

A 7.5-magnitude earthquake and tsunami hit Indonesia on 28 September, destroying homes and hundreds of lives.
Satellite data can be used to support international disaster risk management efforts, such as those in Indonesia. One of the ways in which ESA is contributing to this area is through leading a range of activities in the framework of the Committee on Earth Observation Satellites (CEOS) Working Group on Disasters.
