In 1945, Arthur C. Clarke wrote an article that foresaw the advent of communication satellites. He described three extraterrestrial relays – crewed space stations positioned at equal distances from each other over the equator at an altitude of 36,000 kilometers. They would orbit in sync with Earth’s rotation and their signals would reach almost everyone on the planet.
This prediction was brought into reality by telecommunication company X through Project Y, where instead of three extraterrestrial relays 66 satellites were used. Since Dysprosium as a name for the project didn’t seem right the company went ahead with the name Y as the original plan had more number of satellites. Identify X and Y.
