Hey there! There is some exciting news about the Sentinel Satellites:
The second in the two-satellite Sentinel-1 radar mission is set for launch from French Guiana on 22 April at 21:02 GMT (23:02 CEST) and you can watch it live on the official ESA stream!!For those of you who want get more information about the Sentinel-1 Mission:
The SENTINEL-1 mission includes C-band imaging operating in four exclusive imaging modes with different resolution (down to 5 m) and coverage (up to 400 km). It provides dual polarisation capability, very short revisit times and rapid product delivery. For each observation, precise measurements of spacecraft position and attitude are available.
Synthetic Aperture Radar (SAR) has the advantage of operating at wavelengths not impeded by cloud cover or a lack of illumination and can acquire data over a site during day or night time under all weather conditions. SENTINEL-1, with its C-SAR instrument, can offer reliable, repeated wide area monitoring.
The mission is composed of a constellation of two satellites, SENTINEL-1A and SENTINEL-1B, sharing the same orbital plane. (more information here)
