Speaker Meeting

Friday 17th June 2022
Start time : 20:00

Speaker : Professor Sarah Hörst

Saturn’s largest moon, Titan, is unique in our solar system: below its thick organic haze layer, rivers of methane carve channels into an icy bedrock and flow into large hydrocarbon seas. Could this moon’s lake-mottled surface and thick, organic rich atmosphere be an ideal setting for life as we do not know it? NASA’s Dragonfly mission to Titan will explore Titan’s atmosphere and surface using a rotorcraft lander equipped with state of the art instruments.

Our Speaker will be joining us remotely from the USA via Zoom.
