Voyager 1 will be the first human-made object to reach this distance from Earth, adding to a long list of historic firsts for the mission. Voyager 1 and its twin, Voyager 2, are the only spacecraft to ever operate outside the heliosphere, or the protective bubble of particles and magnetic fields generated by the Sun.
