- Provides high-resolution images using filters to discriminate between metallic and silicate constituents of the Psyche asteroid. - Pair of identical cameras to acquire geologic, compositional, and topographic data.

- Detects and measures the remnant magnetic field of the asteroid. - Two identical high-sensitivity magnetic field sensors located at the middle and outer end of a 6-foot boom.

- Will detect, measure, and map Psyche's elemental composition. - Mounted on a 6-foot boom to distance the sensor from background radiation created by energetic particles interacting with the spacecraft and to provide an unobstructed field of view.

- Measures Psyche's gravity field to high precision. - Combined with topography derived from onboard imagery, this will provide information on the interior structure of Psyche.

Along with the body, they total about the size of a singles tennis court.
