Why does South Pole have less than 24 hours of communications?
It has to do with geography. South Pole is as far south as you can go on the planet. The Earth’s curvature blocks South Pole from seeing most satellites in what is called geosynchronous orbit. That’s a special circle around the earth on a plane that cuts through the equator where satellites appear to remain over one location. These satellites are similar to those that broadcast satellite TV to the satellite dishes mounted on houses.
