Artificial satellites have significantly evolved since the Soviet Union launched Sputnik 1 on October 4, 1957. Roughly the size of a beach ball, the first artificial satellite maintained an orbital velocity of approximately 18,000 miles per hour while emitting a simple radio beep that could be tracked globally. To remain in a stable path, satellites must maintain a precise speed that balances the pull of Earth's gravity with forward momentum; for those in Low Earth Orbit (LEO), this speed is roughly 17,500 miles per hour. As communication satellites reach the end of their operational lives…
