Our first segment is on the experimental satellites called Telstar. They were the world's first communications satellites and Maine played an important role. The "Earth Station" was built in Andover, near Rumford because there were very few radio signals in the area. From the station, scientists could communicate with Telstar as it orbited.
In those days, we could not put satellites into geosynchronous orbit. Therefore, the satellite had to be tracked as it raced across the sky. Each orbit took more than two hours. The "window" in which we could communicate with the satellite was about twenty minutes on each pass.
It's a fascinating story and one that's fun to recount with Butch Phillips who was a technician on the project.
