NASA's Voyager 1 and Voyager 2 are active deep-space spacecraft operating under the Voyager Interstellar Mission. Each spacecraft uses an integrated hydrazine propulsion subsystem with sixteen small thrusters for attitude control and trajectory-correction maneuvers. NASA lists 815 kg launch mass including hydrazine and an approximately 3.8 m spacecraft height; the high-gain antenna and instrument booms extend beyond the central spacecraft structure and are not treated as overall dimensions here.
