Live Earth views from the ISS and NASA's official channels
Live Earth from the ISS
The station's external cameras · 24/7
The stream above is NASA's official 24/7 live feed with high-definition views of Earth from the ISS's external cameras. If it looks black, the station is on the night side of Earth or the signal is switching between relay satellites: try again in a few minutes.
NASA keeps up an almost uninterrupted feed from the ISS thanks to the TDRS (Tracking and Data Relay Satellite System) network, which keeps the station in contact even when it isn't directly overhead a ground station. The external cameras are mounted on different modules and usually point at Earth, though during launches, dockings, or spacewalks the feed switches to dedicated coverage of the event.
It's completely normal for the picture to go black for several minutes at a time: that happens every time the ISS passes through the part of its orbit inside Earth's shadow, which occurs about 16 times a day since the station circles the planet roughly every 90 minutes. You may also see a static "Standby" screen while the signal hands off between different TDRS satellites. Neither case means anything is broken — it's just how the broadcast normally works.
