European Space Agency (ESA) successfully launched Sentinel-2B satellite, fifth of its Sentinel Earth observation satellites part of its multi-billion-euro Copernicus observation program.
The optical imaging satellite was launched on board of a Vega rocket from ESA’s spaceport in French Guiana. It marks overall ninth successful launch of the Vega launcher since its debut in 2012.
- The Sentinel-2B satellite is part of satellites system that monitors Earth. It will join its twin Sentinel-2A, which has been in orbit since 2015. The two satellites will orbit 786 km above Earth, on opposite sides of planet.
- They will take high-resolution, colour and infrared images for a wide array of environmental initiatives, including crop forecasting and monitoring natural disasters.
- Together, they will cover all of Earth’s land surfaces, large islands, inland and coastal waterways every five days, providing more up-to-date images and at higher resolution than have been available.
- It will help track pollution of lakes and coastal waters, monitor land changes and produce disaster maps by providing information on floods, landslide and volcanic eruptions.
About Copernicus observation program
- Copernicus observation program is the world’s largest single earth observation programme. It is directed by the European Commission in partnership with ESA.
- It consists of constellation of seven Sentinel Earth observation satellites. The first satellite of the series was launched in April 2014.
- It aims at achieving a global, continuous, autonomous, high quality, wide range Earth observation capacity by providing accurate, timely and easily accessible information.
- It also aims at improving the management of the environment, understand and mitigate the effects of climate change, and ensure civil security.
- Copernicus observation program is successor of previous European Envisat program which operated from 2002 to 2012.
