Live Space Station Views
Live Space Station Video includes internal views from cameras in the International Space Station's Destiny Laboratory and Harmony module when the resident astronauts are on duty. Earth views from external cameras on the station’s structure will be available during crew off-duty periods.
The video will be accompanied by live audio of conversations between the crew and the Mission Control network.
Television from the station is available only when the complex is in contact with the ground through its high-speed communications antenna and NASA's Tracking and Data Relay Satellite System. During "loss of signal" periods, Internet viewers may see a test pattern or a graphical world map that depicts the station’s location in orbit above the Earth using real-time telemetry sent to Mission Control from the station.
Since the station orbits the Earth once every 90 minutes, it sees a sunrise or a sunset every 45 minutes. When the station is in darkness, external camera video may appear black, but also may provide spectacular views of city lights below.
