A remarkable piece of technology, the oldest government computer still in operation, is over 25 billion kilometers (15.5 billion miles) away from Earth. Voyager’s Ancient ComputersThe Voyager spacecraft, which NASA launched over four decades ago, remains a pioneer of space exploration. According to NASA, a typical instruction on the Voyager computers “takes 80 microseconds, that is about 8,000 instructions per second. In one instance, Voyager 1’s flight data system began transmitting incoherent data back to Earth. Despite being located over 167 astronomical units (AU) from Earth—about 15.5 billion miles—the spacecraft’s systems continue to operate, sending back valuable data to Earth.
