Europe launches fifth Sentinel Earth observation satellite

Europe launches fifth Sentinel (पहरेदार) Earth observation(पर्यवेक्षण) satellite

Europe launched the fifth of its Sentinel Earth observation satellites on Monday as part of its multi-billion-euro Copernicus program to provide speedy images of land, oceans and waterways. The Sentinel-2B satellite, part of a system of satellites that is to monitor Earth, blasted off(उड़ाना)on board a Vega rocket from Europe's spaceport in French Guiana at 8:49 p.m. EST (0149 GMT on Tuesday).

It will join its twin Sentinel-2A, which has been in orbit since 2015, to take high-resolution, color and infrared images for a wide array of environmental initiatives, including crop forecasting and monitoring natural disasters(प्राकृतिक आपदा). The two satellites will orbit 488 miles (786 km) above Earth, on opposite sides of the planet. Together, they will be able to cover all of Earth's land surfaces, large islands, inland (अंतर्देशीय) and coastal waterways every five days, providing more up-to-date images and at higher resolution than have been available. The Copernicus project is described by the European Space Agency (ESA) as the most ambitious Earth observation program to date. The European Union and the ESA have committed funding of more than 8 billion euros ($9 billion) to it until 2020. The first satellite of Europe's planned seven-member network launched in April 2014.
