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 frequencies reduced and can therefore monitor the changes that have occurred in global agricultural crops, offering unprecedented image accuracy. This is a really 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 fits into a monitoring plan named Copernicus, to which 20 satellites responsible for environmental control belong. In fact, there are many objectives that these space constructions aim to fulfill, from monitoring the terrain to mapping ground movements, as happened with its brother Sentinel 1 which managed to monitor earth movements that they caused the earthquake a Napa Valley in California in August 2014.
Sea surfaces, ice surfaces 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 offer prevention data for natural disasters, presenting data that if considered out of the norm can be interpreted quickly and then 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. From the data collected many future choices of governments around the world will therefore depend on it, a great responsibility!
