Explanation: An AI-enabled NASA mission concept for autonomous in-situ exploration and sampling of planetary rings.

PRAXIS (Planetary Rings Autonomous EXploration with In-situ Sampling) is a NASA Innovative Advanced Concepts (NIAC) Phase I mission concept. It proposes an AI-enabled autonomous spacecraft to perform the first in-situ sampling of planetary ring particles, particularly those of Saturn, to study their composition, structure, and evolution.
