The High Definition Earth Viewing (HDEV)

Here’s what the video above is about:


Black Image = International Space Station (ISS) is on the night side of the Earth.

No Audio = Normal. There is no audio by design. Add your own soundtrack.

For a display of the real time ISS location plus the HDEV imagery, visit here:

The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a gray and then black color slate will briefly appear. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. 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.

I find it mind-boggling that from the comfort of my home I can watch something that was unimaginable just a few decades ago. The power of technology is not sufficiently appreciated.

What is in store for humanity in the near-term future — meaning in about the next 20 years or so? We can only make some informed guesses. I will do that in the next post. For now, just marvel at the view.
