On 7 March 2017 ESA launched the new Sentinel-2B satellite from the Kourou spatial station in French Guyana as a twin to the Sentinel-2A which has been in orbit since June 2015. Together, the two Sentinel satellites will cover the surface of the Earth every five days. This improved coverage will be of extreme value to those involved in disaster risk reduction and emergency response efforts as the satellites will reduce the re-visit time to areas affected by disasters worldwide.
