Sentinel-3B is the second in a constellation of earth observation satellites developed by ESA to provide near real time data for the Global Monitoring for Environment and Security Program. Sentinel-3B contains a temperature scanner, colour instrument and altimeter for monitoring the sea and land. The satellite focuses on providing accurate data about the oceans and in addition also provides information about wildfires and vegetation.
SENTINEL 3B was lifted into orbit during the mission ‘Rokot / Briz-KM | Sentinel-3B’, on board a Rokot/Briz-KM space rocket.
The launch took place on April 25, 2018, 5:57 p.m. from 133/3 (133L).
