The Saturnian moon Enceladus is a particularly promising target in the search for extraterrestrial life detection, given its large liquid ocean. While direct sample retrieval from this ocean is made difficult by the kilometers-thick ice shell surrounding it, Enceladus is host to prominent geysers that deliver the contents of this ocean to the surface (featured in this image taken during a Cassini flyby). This is a boon to life detection missions, but any life or biosignatures present in this ejecta would be exposed to the stressors of aerosolization, average surface temperatures nearing -200C, prolonged exposure to near-vacuum conditions, and UV…
