TL;DR: The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a hyperspectral imager on the Mars Reconnaissance Orbiter (MRO) spacecraft as discussed by the authors, which consists of three subassemblies, a gimbaled Optical Sensor Unit (OSU), a Data Processing Unit (DPU), and the Gimbal Motor Electronics (GME).

Subsurface water and clay mineral formation during the early history of Mars
Bethany L. Ehlmann,John F. Mustard,Scott L. Murchie,Jean-Pierre Bibring,Alain Meunier,Abigail A. Fraeman,Yves Langevin +6 more
TL;DR: Clay minerals, recently discovered to be widespread in Mars’s Noachian terrains, indicate long-duration interaction between water and rock over 3.7 billion years ago, and available data indicate substantial Martian clay formation by hydrothermal groundwater circulation and a Noachia rock record dominated by evidence of subsurface waters.
Hydrated silicate minerals on Mars observed by the Mars Reconnaissance Orbiter CRISM instrument

Wolff +35 more
TL;DR: The diversity of phyllosilicate mineralogy is expanded with the identification of kaolinite, chlorite and illite or muscovite, and a new class of hydrated silicate (hydrated silica).

Orbital Identification of Carbonate-Bearing Rocks on Mars
Bethany L. Ehlmann,John F. Mustard,Scott L. Murchie,François Poulet,Janice L. Bishop,Adrian J. Brown,Wendy M. Calvin,Roger N. Clark,David J. Des Marais,Ralph E. Milliken,Leah H. Roach,Ted L. Roush,Gregg A. Swayze,James J. Wray +13 more
TL;DR: The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.

Identification of hydrated silicate minerals on Mars using MRO‐CRISM: Geologic context near Nili Fossae and implications for aqueous alteration
Bethany L. Ehlmann,John F. Mustard,Gregg A. Swayze,Roger N. Clark,Janice L. Bishop,Janice L. Bishop,François Poulet,David J. Des Marais,Leah H. Roach,Ralph E. Milliken,James J. Wray,Olivier S. Barnouin-Jha,Scott L. Murchie +12 more
TL;DR: In this article, the authors used the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter (MRO) to detect alteration minerals in the Noachian terrain west of the Isidis basin.
