Day 216: Could a Saturn moon harbour life?

Carolyn Porco was leader of the imaging team on the Cassini mission to Saturn. Two years before this talk, they’d discovered towering jets erupting from the South Pole of one of Saturn’s moons. After speculating that they were geysers, this implied the possibility of an environment within the moon. In the time since, the Cassini spacecraft has flown closer, enabling the team to find more complex compounds, such as salty water and formaldehyde. The circumstances are such that there may be the conditions to sustain life there. So, imagine the day when we’ll journey to one of Saturn’s moons!
