Earth through different eyes
15 September 2017
In the 1960s, photographs of Earth taken by the first astronauts captured the imaginations of people across the world. The pictures not only became icons for space exploration, but also the fragility of our planet. But astronauts were not the only ones with their eyes on Earth.
Satellites flying hundreds of kilometres above our heads continually capture images of our planet and deliver a wealth of data on our environment. In fact, satellite imagery of Earth pre-dates astronaut photos.
Satellite images show the world through a wide-enough frame so that large-scale features can be observed. In addition, satellites offer frequent visits to monitor changes happening to our planet.
