Three Hera instruments are being used during the flyby, imaging Deimos from a minimum distance of 1000 km away:

- Hera’s black and white 1020x1020 Asteroid Framing Camera used for both navigation and scientific investigation acquires images in visible light.

- Hera’s Hyperscout H hyperspectral imager observes in a range of colours beyond the limits of the human eye, in 25 visible and near-infrared spectral bands, to help characterise mineral makeup.

- Hera’s Thermal Infrared Imager, supplied by the Japan Aerospace Exploration Agency (JAXA) images at the mid-infrared wavelengths to chart surface temperature, in the process revealing physical properties such as roughness, particle size distribution and porosity.
