Satellites have become essential to our survival

06-09-2022

Today’s Video of the Day from the European Space Agency describes why satellite images and measurements of our planet have become “essential to our survival, offering a new outlook of our world.” 

Rising sea levels pose one of the biggest societal threats associated with climate change. According to ESA, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.

“Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage,” reports ESA.

“Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch.”

Dr. Craig Donlon explains that, by understanding planet Earth through satellite measurements, we are able to find evidence of change.
