摘要

The Deimos and Phobos Interior Explorer (DePhine) mission is proposed to explore the origins and evolution of the Martian satellite system. It was a shortlisted candidate for the next (M)edium class mission call of ESA's Cosmic Vision Programme (for launch in 2029/30+). Here, a single spacecraft is launched on an Ariane 6.2, and directly injected into a Mars transfer orbit. The spacecraft then rendezvous first with Deimos, entering a quasi-satellite orbit, performing global surface mapping and a series of very close flyby events. The spacecraft then moves to Phobos, entering into a 2:1 resonance orbit. Similar remote sensing measurements and close flyby events are performed, enabling a detailed comparative analysis of the two planetary bodies. A suite of payload instruments - camera system, radio science, high-frequency radar, magnetometer, gamma ray/neutron spectrometer, dust detectors and a solar wind sensor - performs detailed mapping of the local space environment, surface, structure, interior and diversity. Understanding the origins of both satellites is key to unlocking the evolution of the Martian system and the overarching processes in the formation of the solar system. Are Phobos and Deimos true siblings, originating from the same source and sharing the same formation scenario? Or do they differ, and how? Are they rubble piles or solid bodies? Do they possess hidden deposits of water ice in their interiors? This paper will therefore report on the scientific justification, mission analysis, and focus on the (sub)system design of performing the DePhine mission. The mission was deemed to be feasible, and can be conceived - programmatically and technically - within the boundary conditions of an ESA (M)edium class mission opportunity. Optional mass (& cost) saving measures are also available. Reducing the number of Deimos flybys and entering a 3:1 resonance orbit with Phobos would save delta-v, and account for the uncertainty in the launcher performance. Alterna
