In order to effectively relay the data the spacecraft collected back to NASA, the probe was equipped with a number of technologies, including the following:

• Imaging science system: a set of cameras with filters to capture images
• Ultraviolet Spectrometers: senses ultraviolet light to determine height, depth, density, and other characteristics of planets and stars
• Infrared Interferometer Spectrometer and Radiometer: serves as a thermometer while also measuring the elements present on a body and measuring ultraviolet, visible, and infrared light frequencies
• Photopolarimeter System: a powerful telescope used to observe the particles that make up the atmospheres and rings of celestial bodies

The craft also carried a number of experimental technologies, bringing the total cost to build Voyager 2 to 895 million US dollars.
