When I was a child, I always dreamed about watching Earth from space. Back in the 1980s, we were almost sure that around the year 2000, space travel would be so common. Remember TV shows like “Space: 1999”. Unfortunately, the space race lost its momentum during the 1990s and 2000s.
But thanks to the Internet and computer science, we all able to see the earth from space. And live! And HD! 24 hours a day (the feed will sometimes go down as the signal switches between the cameras – the screen is grey when the cameras are down)!
The High Definition Earth Viewing (HDEV) experiment consists of four cameras that have been attached outside of the ISS – International Space Station.
It is hard to see anything when the International Space Station is on the dark side of our planet, but be patient, you’ll be on the sunny side in a few minutes (the orbital period of the ISS is 92.69 minutes). Its average speed is 7.66 kilometers per second (27,600 km/h; 17,100 mph).
I am a software developer, a former road racing cyclist, and a science enthusiast. Also an animal lover! I write about the planet Earth and science on this website, ourplnt.com. You can check out my social media profiles by clicking on their icons.
