NASA has set up a new livestream for their High Definition Earth Viewing experiment.
It uses four HD cameras on the exterior of the International Space Station to capture awe-inspiring images of earth that are then broadcast directly down to earth using real-time video.
Each of the cameras are enclosed in a pressurized and temperature controlled housing unit. Information gathered will be used to analyze the affect of space on the video quality and can help engineers decide which cameras are best used for future missions.
These cameras do not offer zoom, pan, or tilt mechanisms and are fixed in position for capturing imagery of the earth’s surface.
The cameras have been in place and streaming since April 30, switching between the various views. A gray and then black color slate may briefly appear, since the ISS is in darkness during part of each orbit.
Viewers can also stay tuned to updates from the station’s crew members and a map tracking the space station’s exact location.
