Using Remote Sensing to Measure Land Deformation
The European Space Agency has developed a new land data processor to create maps of land deformation. Called Wide Area Processor (WAP), the processes uses radar data to measure millimeter terrain deformations. Changes in the surface height of a landscape occur over time. Sinking of the earth can happen as a result of mining, earthquakes, or natural gas extraction. [...]

Monitoring Driver Fatigue from Space
The ESA has recently released a small spin-off company that is going to help drivers around the world stay a little bit safer with the help of space age technology. EstrellaSat’s job is to create long-distance monitoring technology specifically designed to help predict the movements of drivers who work carting mine loads to and from [...]
