This space mission is composed of two satellites, Sentinel-1A and Sentinel-1B, that carry a C-band synthetic-aperture radar instrument which provides a collection of data in all-weather, day or night. The first satellite, Sentinel-1A, was launched on 3 April 2014, and Sentinel-1B was launched on 25 April 2016. Both satellites lifted off from the same location in Kourou, French Guiana, and each on a Soyuz rocket. Sentinel-1C and 1D are in development with launch dates to be determined. S1 collects data at 5 meter spatial resolution and has a revisit time of 3 days. (See also [[GERMAN Wikipedia>>https://de.wikipedia.org/wiki/Sentinel-1]])

22 22  **[[Sentinel-2>>https://sentinel.esa.int/web/sentinel/missions/sentinel-2]] **(S2) is an Earth observation mission developed by ESA as part of the Copernicus Programme to perform terrestrial observations in support of services such as forest monitoring, land cover changes detection, and natural disaster management. It consists of two identical satellites built by Airbus DS, Sentinel-2A and Sentinel-2B, with two additional satellites being constructed by Thales Alenia Space. S2 collects data at 10/20/60 meter spatial resolution for 13 spectral bands and has a revisit time of 5 days. (See also [[GERMAN Wikipedia>>https://de.wikipedia.org/wiki/Sentinel-2]])
