Future planetary missions will require advanced, smart, low resource payloads (P/Ls) and satellites1,2 to enable the exploration of the solar system in a more frequent, timely and multi-mission manner with reasonable cost. The concept of highly integrated payload architectures was introduced during the re-assessment of the payload of the BepiColombo Mercury Planetary Orbiter3. Considerable mass and power savings were achieved throughout the instrumentation by better definition of the instruments design, higher integration and identification of resource drivers4. Higher integration and associated synergy effects permit optimisation of the payload performance at minimum resource requirements while meeting demanding science requirements. This promising concept has been applied to a set of hypothetical Planetary Technical Reference Studies11 (PTRS) on missions to Venus5, Jupiter/Europa6, Deimos7, Mars8 and the investigation of the Interstellar Heliopause9. The needs on future instrumentation were investigated for these mission concepts and potential instruments were proposed10. A demonstration programme is now proposed in form of an elegant breadboard that consists of a photon counting laser altimeter, a stereoscopic high resolution camera, and a broadband radiometric mapping spectrometer. The aim of the activity is to demonstrate to feasibility of such a miniaturised, low resource and highly integrated payload based on innovative instrument designs. The activity shall thereby provide a clear detailed definition of the technical and managerial aspects for implementation into potential future planetary space science missions.
