SwRI Models Point to a Potentially Diverse Metabolic Menu at Enceladus – Parabolic Arc


This figure illustrates a cross-section of Enceladus, showing a summary of the processes SwRI scientists modeled in the Saturn moon. Oxidants produced in the surface ice when water molecules are broken apart by radiation can combine with reductants produced by hydrothermal activity and other water-rock reactions, creating an energy source for potential life in the ocean.

SAN ANTONIO, Texas (SwRI PR) Using data from NASA’s Cassini spacecraft, scientists at Southwest Research Institute (SwRI) modeled chemical processes in the subsurface ocean of Saturn’s moon Enceladus. The studies indicate the possibility that a varied metabolic menu could support a potentially diverse microbial community in the liquid water ocean beneath the moon’s icy facade. ....

SAN ANTONIO Dec. 16, 2020 Using data from NASA s Cassini spacecraft, scientists at Southwest Research Institute (SwRI) modeled chemical processes in the subsurface ocean of Saturn s moon Enceladus. The studies indicate the possibility that a varied metabolic menu could support a potentially diverse microbial community in the liquid water ocean beneath the moon s icy facade.
Prior to its deorbit in September of 2017, Cassini sampled the plume of ice grains and water vapor erupting from cracks on the icy surface of Enceladus, discovering molecular hydrogen, a potential food source for microbes. A new paper published in the planetary science journal Icarus explores other potential energy sources. ....
