At 23:32 on the 3rd of the Paris time (Beijing time at 05:02 on the 4th), a Russian “coalition” carrier rocket was launched from the Kourou Space Center in French Guiana to launch the “Sentinel-1A” Environmental monitoring satellite successfully into orbit. According to the European Space Agency, the Sentinel-1A satellite weighs about 2.3 tons and is manufactured by Thales Alenia Aerospace. It carries an advanced C-band radar that provides real-time imagery of land and sea surfaces in Europe, Canada and the polar regions, day and night, regardless of weather conditions. According to the launch of the European Ariane Space Agency, “Sentinel” series of earth observation satellites is the EU’s global environment and safety monitoring system (ie Copernicus plan)
