Voyager :The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-40-year journey since their 1977 launches, they each are much farther away from Earth and the sun than Pluto.
Voyager/ISS-WAC :The Imaging Science Subsystem (ISS) is a modified version of the slow scan vidicon camera designs that were used in the earlier Mariner flights. The Wide Angle Camera (WAC) is a television-type camera with a low resolution 200 mm wide-angle lens with an aperture of f/3.
