HiPOD 22 Jul 22: Possible Smectites in Noctis Labyrinthus

Data from the CRISM instrument on MRO shows smectites on the floor of this trough in Noctis Labyrinthus. Our image at this location can help to identify the units that correspond to these mineralogies. Smectite is a type of clay mineral that undergoes reversible expansion on absorbing water.
