Notes

  • NASA selected the PRAXIS (Planetary Rings Autonomous EXploration with In-situ Sampling) mission concept for NIAC 2026 Phase I funding.
  • PRAXIS utilizes a bio-inspired robotic explorer controlled by an AI model to sample planetary ring particles.
  • The mission aims to address key scientific questions regarding the formation, evolution, and composition of planetary rings.
  • Operational mechanism: The spacecraft performs a 'touch-and-go' sampling maneuver using a long deployable boom while grazing the ring plane to avoid collision hazards.
  • On-board instruments will analyze particle size, porosity, and composition.
  • Phase I funding supports simulations and system design; Phase II would allow for the development of a physical prototype.
  • The technology is designed to be scalable for missions to multiple ringed planets.
