Three photos taken by the European Remote Sensing satellite ERS-1. One photo shows an artist’s impression of the ERS-1 above Earth, and is approximately 20 x 20 cm. Photo two shows part of the Black Forest (Schwarzwald, Black Forest, Germany), captured by the ERS-1’s radar. Photo three: the area Djebel Amour in Algeria. One pixel on these two latest photos is 12.5 m. Very detailed and sharp images from 1991!
