Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from cracks in its south pole. Data returned from the Cassini mission have identified the presence of salts and organic matter within these ejected plume particles. Such combination...

Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from cracks in its south pole.

In particular, the fundamental behavior of organics in frozen brine systems upon exposure to relevant Enceladus surface conditions is an important aspect that has not been explored to date (e.g. how they organize and partition relative to the salt minerals within the ice matrix).
