Recently, on Wednesday, the European Union succeeded in launching its new advanced Sentinel Earth Observation Satellite into space. The Earth Observation Satellite is called Sentinel-3B and flew into space on a Russian Rockot carrier. The Russian Rockot booster exploded the Sentinel-3B satellite from the Plesetsk Cosmodrome in northwestern Russia at 17:57:51 GMT (1
The main objective of The Sentinel 3B satellite is to monitor the Earth's ocean. Together with this it will map the growth of the vegetation on the earth's surface and measure the thinning layers of ice. The Sentinel-3B was the seventh rocket launched by the European Union for its ambitious Copernicus mission. The European Union has informed that its Copernicus mission is to create a fleet of Earth observation satellites in space so that people on Earth can be provided with a great deal of data about the Earth. Earth's data can easily be accessed by policymakers, scientists, businesses and the general public, and used according to their needs.
The Copernicus program is a partnership between the European Space Agency (ESA), EUMETSAT and the European Commission conducting earth science and environmental research from orbit. The program is being funded by ESA and with the deployment of the Sentinel B rocket in orbit, Copernicus' first satellite constellation has been completed. The original name of the Copernicus mission is Global Monitoring for Environment and Safety (GMES) and is managed by the European Commission.
The Sentinel 3B satellite has joined its twin Sentinel-3A, which was launched in 2016 by the Rockot launcher. Both will be orbiting the earth in a pair and will incorporate the same Ocean and Land Color Instrument (OLCI) instrument that carries five cameras. Both Sentinel 3A and 3B will operate in the same orbital plane and be separated by only 140 degrees.
According to the latest reports, the upper tier of the Rockot launcher has sent the sentinel-3B satellite into a Sun-Synchronic orbit (SSO) at a height of about 503 miles (810 kilometers), tilted at 98.65 degrees. The Sentinel 3B rocket was built by Thales Alenia Space. The satellite weighs almost 1,150 kilograms and has a lifespan of about seven years, but the amount of fuel it carries can get it up and running for twelve years.
