Fun fact: (Space Probe)Voyager (launched into space in 1977) has an 8-kilobyte active memory in its main computers, versus a standard 128 megabytes in new desktop PCs for home use. That is to say, your home computer has 16,000 times more processing power than the computer running a spacecraft that has left the solar system."
