During periods of loss of signal with the ground or when HDEV is not operating, a gray color slate or previously recorded video may be seen. Analysis of this experiment will be conducted to assess the effects of the space environment on the equipment and video quality which may help decisions about cameras for future missions. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. Between camera switches, a gray and then black color slate will briefly appear. While the experiment is operational, views will typically sequence though the different cameras. Video from these cameras is transmitted back to earth and also streamed live on this channel.
This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module.
