1. Imaging Science System (ISS): Includes two television cameras, a wide-angle camera, and a narrow-angle camera, used to capture high-resolution images of planets, moons, rings, and other celestial bodies.
2. Ultraviolet Spectrometer (UVS): Measures ultraviolet radiation emitted by gases in the atmospheres of planets and moons, providing information about their composition and structure.
3. Infrared Interferometer Spectrometer and Radiometer (IRIS): Measures infrared radiation to determine the temperature and composition of planetary atmospheres and surfaces.
4. Magnetometer: Measures the strength and direction of magnetic fields in the vicinity of planets and moons.
5. Plasma Science Experiment (PLS): Collects data about the charged particles and plasma in space, including solar wind and interstellar plasma.
6. Low-Energy Charged Particle Instrument (LECP): Measures low-energy charged particles, such as electrons and protons, in space.
7. Cosmic Ray System (CRS): Detects and analyzes high-energy cosmic rays from distant galaxies.
8. Planetary Radio Astronomy (PRA): Uses the spacecraft's radio antenna to study radio emissions from planets and moons.
9. Optical Calibration Target: A small plaque mounted on the spacecraft that provides a known target for calibrating the cameras.
10. Triaxial Fluxgate Magnetometer: A backup magnetometer that measures magnetic fields in three directions.
In addition to these instruments, Voyager 2 carries a Golden Record, a phonograph record containing sounds and images representing Earth and its inhabitants, intended as a message to any extraterrestrial civilizations that may encounter the spacecraft in the distant future.
