Planetary Exploration 3.0: Radically Adaptive Space Systems

The Planetary Exploration 3.0 paradigm represents a significant departure from traditional, incremental approaches to space exploration. By advocating for radically adaptive space systems, this concept aims to overcome the limitations imposed by long cruise times and the need for iterative missions, particularly in the outer Solar System. The core enabler of PE 3.0 is the software-defined space system (SDSS), which allows for in-flight adaptation and reconfiguration of spacecraft functions. This adaptability is crucial for exploring unvisited worlds with unknown environments. The Keck Institute workshop highlights the key aspects of PE 3.0, including systems engineering, SDSS technologies, and onboard intelligence. The mission concepts presented, such as a Neptune/Triton smart flyby and an ocean world explorer, demonstrate the potential of this paradigm to address fundamental questions in planetary science. However, the successful implementation of PE 3.0 requires overcoming significant technological and engineering challenges, particularly in the areas of reconfigurable hardware, autonomous science, and verification & validation. The shift towards greater onboard autonomy also necessitates careful consideration of risk management and system resilience.
