The solution-mediated formation of calcium sulfate minerals, ie gypsum, anhydrite and
bassanite, is a common process in both natural and engineered settings. It plays a key role …

Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

The presence of perennially wet surface environments on early Mars is well documented,,
but little is known about short-term episodicity in the early hydroclimate. Post-depositional …

Gale Crater contains a 5.2 km-high central mound of layered material that is largely
sedimentary in origin and has been considered as a potential landing site for both the MER …

By the time eukaryotic life or photosynthesis evolved on Earth, the martian surface had
become extremely inhospitable, but the subsurface of Mars could potentially have contained …

Carbonates are key minerals for understanding ancient Martian environments because they
are indicators of potentially habitable, neutral‐to‐alkaline water and may be an important …

Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis
Mons. Using orbital data, we mapped the crater infillings and measured their geometry to …

The Mars' climate is cold and dry in the most recent epoch, and liquid water activities are
considered extremely limited. Previous orbital data only show sporadic hydrous minerals in …

Ongoing research on martian meteorites and a new set of observations of carbonate
minerals provided by an unprecedented series of robotic missions to Mars in the past 15 …

The Meridiani Planum region of Mars has been identified as a region of past aqueous
activity by a combination of orbital and in situ observations that revealed evidence for sulfate …
