Abstract
Presented is a minimalistic Pluto/Charon reconnaissance flyby mission. We investigated this concept with three objectives in mind: (1) to perform a scientifically-sound first exploration, (2) to keep the overall cost affordable, and (3) to demonstrate how a revitalized NASA planetary program can operate through a partnership between government, university,and industry. Key ideas for affordability of the mission are: (a) science focused on surface imaging (primary) and an atmospheric occulatation experiment (secondary), (b) battery-powered design eliminating requirement for RTG, (c) use of the Proton launch vehicle, (d) high inheritance including the imaging instrument based on Mars Observer Camera. The point design of the mission, spacecraft and instruments is presented to demonstrate technical and financial feasibility as a low-cost mission, including mission operations and substantial contigency. The challenges of the restricted power budget and instrument data acquisition from a simple spacecraft platform are described in detail. Technical risk assessment is stressed throughout. Primary focus is on genuine simplicity of design and operations.
