At this moment, the NASA feed cut out. “The feed in question is the High Definition Earth Viewing experiment. Anytime the ISS has a signal, that feed is sending down video,” NASA said sustaning that when the system loses signal, the video stream goes dark. “The feed is not switched manually. It’s all done automatically. There’s nobody at a control board. We used a space-based data relay network.,” said the spokesperson. As about the strange light / object in the video, NASA suggests the possibility to be a reflection on the lens of the camera, radiation hitting a sensor in the High Definition Earth Viewing system, a satellite, a meteor, or one of the tens of thousands bits of space debris currently circling the planet. At least for the moment, it seems no more clarification is possible.
