Started streaming on Jun 27, 2018. See live views of Earth from the International Space Station coming to you by NASA's High Definition Earth Viewing (HDEV) experiment.
While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.
The ISS passes into the dark side of the earth for roughly half of each of its 92-minute orbits. As the Space Station passes into a period of night every 46 mins video is unavailable. Max speed of ISS is 27,600 km/h.
