Every minute of every day, satellites are taking photos of the weather, transmitting TV and radio signals, monitoring the climate, and linking people around the world. And it’s no exaggeration to say that they have become an essential part of our infrastructure. Sixty-five years after the launch of Sputnik in 1957, there are thousands of satellites orbiting Earth. However, there is one thing you can be guaranteed to see moving in the sky every night, no matter where you live on the planet: satellites. You can’t be guaranteed to see each of them every night. Sometimes, a display of the fabled aurora paints the northern sky with searchlight beams of scarlet and swaying curtains of highlighter-pen green.īut all these things only happen occasionally. Stars rise and set during the night constellations come and go as the seasons pass planets waltz along the ecliptic, visiting the zodiacal constellations on their nonstop sightseeing tour of the heavens and shooting stars zip across the sky. The High Definition Earth Viewing (HDEV) experiment mounted on the ISS External Payload Facility of the European Space Agency’s Columbus module was activated Apand after 5 years and 79 days was viewed by more than 318 million viewers across the globe on USTREAM alone.Lots of things change in the night sky. ![]() Thank You to all who shared in experiencing and using the HDEV views of Earth from the ISS to make HDEV so much more than a Technology Demonstration Payload! After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life. The loop will have “Previously Recorded” on the image to distinguish it from the live stream from the Node 2 camera. If the Node 2 camera is not available due to operational considerations for a longer period of time, a continuous loop of recorded HDEV imagery will be displayed. The camera is looking forward at an angle so that the International Docking Adapter 2 (IDA2) is visible. Node 2 is located on the forward part of the ISS. Currently, live views from the ISS are streaming from an external camera mounted on the ISS module called Node 2. ![]()
