[[File:Voyager spacecraft structure vector.svg|thumb|right|upright=1.2|alt=A space probe with squat cylindrical body topped by a large parabolic radio antenna dish pointing left, a three-element radioisotope thermoelectric generator on a boom extending down, and scientific instruments on a boom extending up. A disk is fixed to the body facing front left. A long triaxial boom extends down left and two radio antennas extend down left and down right.|
The Voyager spacecraft weighs 773 kilograms. Of this, 105 kilograms are scientific instruments.<ref>{{cite web|last=Haynes|first=Robert|title=How We Get Pictures from Space, Revised Edition|url=http://ntrs.nasa.gov/search.jsp?R=19880001821|work=NASA facts|publisher=NTRS}}</ref> The identical ''Voyager'' spacecraft use three-axis-stabilized [[guidance system]]s that use [[gyroscopic]] and [[accelerometer]] inputs to their [[attitude control]] computers to point their [[high-gain antenna]]s towards [[the Earth]] and their scientific instruments pointed towards their targets, sometimes with the help of a movable instrument platform for the smaller instruments and the [[video camera tube|electronic photography]] system.
