Last month, the privately funded Dragon spacecraft delivered the nationally funded High Definition Earth Viewing (HDEV) experiment to the globally funded International Space Station. We are all the better for it. Astronauts have since installed four HD cameras onto the exterior of the International Space Station, thereby providing the rest of us with a LIVE feed of our planet from 220 miles overhead. You can check it out for yourself at this link, or by clicking on the video below. You may find that the feed is sometimes black (when the ISS is over the nightside of the Earth) or gray (when the feed is switching between cameras). Don’t despair. The live feed generally returns in short order. Enjoy.
