As part of an experiment to try out the durability of cameras in space, a package of four cameras have been attached to the International Space Station. The cameras are facing front, aft and straight down. The video stream will cycle through all four cameras.
The video stream is live, but there will be interruptions for technical reasons. If the image is black, the ISS is looking at the night side of the Earth.
Where is the International Space Station right now? Check out the following two sites that show real time tracking of the ISS.
