It is the twin brother of a satellite that was left in 2014, the Sentinel-1A. “A finger on the pulse of our planet,” the Dutch astronaut André Kuipers said the mission earlier.
The Sentinel satellites see where changes include the soil. “We can for example take the dikes monitored continuously in the Netherlands. The satellite sees as seven hundred kilometers altitude that a building sags a millimeter,” mission leader Josef Aschbacher explains.
The satellites can measure where the sea ice exactly, so that ships can be guided along it. That’s important, because the next few years, probably more ships sail through Arctic waters. This is due to the shrinking of the ice caps

Aschbacher:. “We recently did a test on the Baltic Sea, to see how much money can be saved if we are masters can better tell what routes they should avoid. Just on the Baltic Sea was to save 25 per year to 110 million. “
the Sentinels can also monitor crops on earth. The launched satellite will cost over 200 million euros. The solar panels are made by Airbus Defence and Space in Leiden, the former Fokker Aerospace.
The probe is part of a larger European project, which cost about eight billion euros.
