World-renowned musician Mike Oldfield, composer of the music used in ESA's Sentinel-1 video, is a big space fan. From his home, Mike and his two sons (the future generation of space scientists and explorers) sent this message to ESA and the Sentinel-1 team with best wishes for the upcoming launch.

Sentinel-1 is an important mission, its launch will mark a new shift in Earth observation, focusing on operational missions to support users for decades to come. This first mission carries an advanced radar sensor to image Earth’s surface through cloud and rain and regardless of whether it is day or night.
