Pressures in the hydrospheres of large ocean worlds extend to ranges exceeding those in
Earth deepest oceans. In this regime, dense water ices and other high-pressure phases …

NASA's Dragonfly mission will send a rotorcraft lander to the surface of Titan in the mid-
2030s. Dragonfly's science themes include investigation of Titan's prebiotic chemistry …

Hydrogen from serpentinization is a source of chemical energy for some life forms on Earth.
It is a potential fuel for life in the subsurface of Mars and in the icy ocean worlds in the outer …

Geophysical measurements can reveal the structures and thermal states of icy ocean
worlds. The interior density, temperature, sound speed, and electrical conductivity thus …

The icy outer shell of Jupiter's moon Europa is believed to be geologically active, and
geological processes within the ice may be key to sustaining chemical disequilibria and …

Cassini revealed that Saturn's Moon Enceladus hosts a subsurface ocean that meets the
accepted criteria for habitability with bio-essential elements and compounds, liquid water …

Gibbs energy representations for ices II, III, V, and VI are reported. These were constructed
using new measurements of volumes at high pressure over a range of low temperatures …

Enceladus is the first world beyond Earth for which we have diagnostic observational data
concerning the composition of an extant ocean. The abundances of chemical species in the …

The open‐source PlanetProfile framework was developed to investigate the interior structure
of icy moons based on collectively matching their observed properties and comparative …

Abstract Thanks to the Cassini–Huygens mission, Titan, the pale orange dot of Pioneer and
Voyager encounters, has been revealed to be a dynamic, hydrologically shaped, organic …
