Low-temperature aqueous alteration of chondrites
Chondritic meteorites (chondrites) contain evidence for the interaction of liquid water with
the interiors of small bodies early in Solar System history. Here we review the processes …

Endogenous CO2 ice mixture on the surface of Europa and no detection of plume activity
Jupiter's moon Europa has a subsurface ocean beneath an icy crust. Conditions within the
ocean are unknown, and it is unclear whether it is connected to the surface. We observed …
