NASA has launched a livestream from the International Space Station. Four HD cameras attached to the ISS are now providing an around-the-clock perspective of Earth, including audio conversations between the crew and Mission Control. You can watch it live right here.


The live video from the ISS includes internal views when the crew is on-duty, and Earth views at other times. The video is only available when the ISS is in contact with the ground; during "loss of signal" periods, viewers will see a blue screen.

Because the station orbits the Earth once every 90 minutes, the cameras will capture a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera shots may appear black, but can sometimes provide spectacular views of lightning or city lights below.
