A new European and American satellite is preparing for launch with a SpaceX rocket this weekend. Sentinel-6’s mission will be to measure sea level, using laser beams to calculate ocean levels in connection with ice melting.
“It may be difficult to imagine, but from a height of 1,300 kilometers, we can measure – of course with some algorithms and calculations – the change in sea level with millimeter accuracy. And that’s what our satellite will do,” European Space Observation Director Josef Asbacher told Techodom.
ESA hopes the launch of sentinel-6 will go better than that of vega which a few days ago failed eight minutes after takeoff, destroying the two satellites it was carrying.
Sentinel-6 will become the eighth satellite of the Sentinel series, which is part of the European Copernicus Earth observation program.
Satellites that are already in orbit measure everything from air pollution to flooding.
At present, ESA has contracts for six more Sentinel satellites to measure additional parameters from space, such as soil drought or urbanization.
According to Asbacher, “with these six new missions, we enter Copernicus 2, the next phase of Copernicus. These are different types of missions with very different sensors.
Devices that measure air pollution, instruments for measuring carbon dioxide with unprecedented accuracy, we measure the ice cover of poles, parameters of climate, food safety, both in Europe and globally.”
The launch of the first of the six satellites is scheduled for 2025. It is he who will measure carbon dioxide and distinguish the difference between natural and anthropogenic emissions.
