In the 80’s a space shuttle used an Imaging Radar Instrument that showed rivers that use to flow in the eastern Sahara. I have tried to find the images but have not been able to. I am fascinated with what the Sahara Desert use to be like and what possibly may lie beneath it such as underground water and/or minerals and oil.
