PRAXIS: Planetary Rings Autonomous EXploration with In-situ Sampling

PRAXIS: Planetary Rings Autonomous EXploration with In-situ Sampling. Marco QuadrelliNASA Jet Propulsion Laboratory Humanity has never touched the particles of a planetary ring, but if we were able to get close enough and sample them, it will transform understanding of ring structure and origins for Saturn (dense), Uranus and Neptune (tenuous), rings of other objects such as Centaurs Chariklo and Chiron, and even early […]
