  Voyager 3 is a concept mission that sends a space telescope to the
interstellar medium in a reasonable amount of time. Voyager 3 would take a
direct image of an exoplanet using the solar gravitational lensing at the
distance of 550 astronomical unit (AU). The spacecraft would use its suite of
scientific instruments to study the environment of the local solar system and
interstellar medium and finalize its primary mission by imaging an exoplanet.
Two potential architectures are proposed to meet this mission directive, using
multiple gravitational assists and sizable electric propulsion burns to achieve
the high escape speeds necessary to reach 550 AU. This paper expands on the
science mission objectives, trajectory, and the preliminary design of the
baseline spacecraft.
