Surely you've seen all those wonderful photos of planet Earth taken from the International Space Station - but have you ever wondered how astronauts take those pics?
With cameras, of course. Lots and lots of them.
This NASA image shows a large selection of cameras and lenses that are available in the ISS for Crew Earth Observation, located in the Service Module part of the Russian segment and near one of the windows used to take photos of Earth.
