NASA selects PRAXIS mission concept to sample planet rings
NASA has selected PRAXIS (Planetary Rings Autonomous Exploration with In-situ Sampling) for its NIAC 2026 phase I funding. This bio-inspired robotic explorer, driven by an artificial intelligence (AI) model, aims to directly sample particles from planetary ring systems—a first for any mission. PRAXIS will graze the ring plane and use a deployable boom to collect samples, addressing fundamental questions about how planetary rings form, evolve, and what they are made of, as identified by NASA's Planetary Science Decadal Survey.
Key Points
- NASA has selected the PRAXIS mission concept for funding to explore planetary rings.
- PRAXIS is an AI-driven robotic explorer designed for in-situ sampling of ring particles.
- The mission aims to answer key questions about the formation, evolution, and composition of planetary rings.
- It will be the first mission to directly sample particles from planetary ring systems.
