On June 23 last year the satellite flew among the stars Sentinel 2A, a device that will monitor the health of our planet using i colors. That's right, as the satellite is equipped with a special camera connected to the Sentinel 1A radar, which can scrutinize large swathes of territory using reduced frequencies and which can therefore monitor the changes that have occurred in global agricultural crops, offering an accuracy of unprecedented images. This is a truly accurate analysis, as thanks to these detection tools it is also possible to evaluate the levels of chlorophyll plants and collect biological and geophysical data on the health of our planet.
The Sentinel 2A satellite is part of a monitoring plan called Copernicus, which includes 20 satellites responsible for environmental control. Many are, in fact, the objectives to which these spatial constructions intend to fulfill, from monitoring the land up to mapping the movements of the soil, as happened with his brother Sentinel 1 who managed to monitor the land movements that caused the earthquake in Napa Valley in California in August 2014.
The surfaces of the sea, ice and oil spills are just some of the phenomena that Sentinel 2A can monitor from high in the skies and it is the first satellite capable of offering prevention data for natural disasters, presenting data that if considered outside the norm can be interpreted quickly and therefore transmitted to the people for avoid disasters. Not only that, as the satellite's task continues with the creation of a database of information on the earth's surface and the atmosphere, which will be used to support environmental and security policies. Many future choices of governments around the world will therefore depend on the data collected, a great responsibility!
