Unlike Voyager and Pioneer the next space craft to leave the solar system, New Horizons, is not carrying a message from planet Earth. That can still be fixed. Onboard of New Horizons there is a computer that can be used to store a message when mission is completed beyond Pluto. What will the message be? How will possible aliens hack into the New Horizons computer to find the message? I’m curious to learn more about this project.
