From their orbiting home on the International Space Station (ISS), astronauts have a view unlike anything most of us will ever see. In the past 20 years, they have shot millions of photographs, and it is not just a hobby. It is an important scientific job, and one the astronauts need to be trained to do. Every photograph is valuable because it might be inspirational or scientifically useful. So the astronauts and the Earth Science and Remote Sensing team work together before, during, and after every mission to get the most out of every shot.
