Tracking Cities at Night from the Space Station

  • Rating12345

ESA astronaut André Kuipers has installed ‘NightPod’ on the International Space Station, an aid for taking night-time pictures of Earth. The first batch of pictures offer stunning images of cities at night.
 
Any amateur photographer knows the problems of taking pictures at night: the low shutter speeds required to capture enough light make images prone to camera shake. Blurry and unsharp pictures are the result. Professional photographers use tripods to steady their camera and take clearer pictures.  
 
The International Space Station orbits Earth at 7 km/s so using a tripod is not an option for night-time photography. Even if the camera is perfectly still, the Station moves so fast any images of Earth at night will still look blurred.
