Some of the views you've seen of Earth from low-Earth orbit satellites or even from the space shuttle at some of its lowest altitudes are essentially the exact same view you get out of the window of this craft. And we've got some spectacular footage on our Web site... ... [So you...
Electrons circle the nucleus in fixed orbits -- a simplified way to think about it is to imagine how satellites orbit the Earth. There's a huge amount of theory around electron orbitals, but to understand light there is just one key fact to understand: An electron has a natural orbit that...
Satellite internet quality heavily depends on your dish's visibility with your provider's satellites in Earth's orbit. If the dish isn't pointed in the optimal direction, you're not catching the best signal. Also, if there are dense objects between the satellites and the dish (buildings, tr...
Like acell phone, aGPS receiverrelies on radio waves. But instead of using towers on the ground, it communicates with satellites that orbit the Earth. There are currently 27 GPS satellites in orbit -- 24 are in active use and 3 act as a backup in case another satellite fails. ...
