Speaker: Geoffrey Landis

Researcher- John Glenn Research Center

Topic: Triton's Mysteries

Description of Talk:

Triton, the largest moon of Neptune, is Pluto’s big brother: mysterious, icy, backwards, and pink. Icy? The mountains of Triton are made of water ice, and the geysers are liquid nitrogen. Backwards? It’s the only large moon in the solar system that orbits retrograde, in the opposite direction from the planet’s spin. Pink? Yes, it has a surface partially covered with tholins, complex organic molecules with a peculiar reddish-pink tint. Icy on the outside, liquid on the inside, it has only been visited once, by the Voyager-2 probe, which flew past it on the way out of the solar system. 

Dr. Landis will talk about a concept for a future mission to try to learn more about Triton’s mysteries, a mission to send a vehicle to land on Triton and then hop from site to site using a radioisotope-powered rocket engine.
