The Mississippi River is without doubt one of the world’s main river techniques in dimension, habitat range and organic productiveness. The river flows 3766 km from its supply at Lake Itasca by the centre of the continental United States to the Gulf of Mexico.
The realm pictured right here reveals the place the Mississippi straddles the states of Louisiana and Mississippi. The picture combines three radar acquisitions from the Sentinel-1 mission taken 12 days aside to indicate modifications in crop and land situations over time. Vibrant colors within the picture come from modifications on the bottom which have occurred between acquisitions.
Water our bodies, together with the Mississippi River, seen within the far proper, and Catahoula Lake, within the far left, seem black as water surfaces replicate the radar sign away from the satellite tv for pc. If we take a more in-depth look, we will see cargo ships travelling alongside the Mississippi. Ships from 7 April 2022 seem in crimson, these from 19 April seem in inexperienced, and people from 1 Might seem in blue.

Wanting forward, the upcoming Sentinel-1C satellite tv for pc scheduled to elevate off on ESA’s Vega-C rocket from Europe’s Spaceport in French Guiana within the first half of 2023, will proceed the crucial job of delivering key radar imagery for a variety of providers, functions and science.
The satellite tv for pc is now at Thales Alenia Area’s Cannes plant on the French Riviera after it efficiently accomplished all integration assessments this summer season in Rome, Italy. It should now bear a ultimate collection of assessments in Cannes, together with radiofrequency efficiency checks within the facility’s anechoic chamber.
