Evidence for marine sedimentary rocks in Utopia Planitia: Zhurong rover observations
Decades of research using remotely sensed data have extracted evidence for the presence
of an ocean in the northern lowlands of Mars in the Hesperian (∼ 3.3 Ga), but these claims …

Did Mars Possess a Dense Atmosphere During the First Million Years?
It is not yet entirely clear whether Mars began as a warm and wet planet that evolved
towards the present-day cold and dry body or if it always was cold and dry with just some …

Mars: life, subglacial oceans, abiogenic photosynthesis, seasonal increases and replenishment of atmospheric oxygen
The discovery and subsequent investigations of atmospheric oxygen on Mars are reviewed.
Free oxygen is a biomarker produced by photosynthesizing organisms. Oxygen is reactive …

Stratigraphic relationships in Jezero crater, Mars: Constraints on the timing of fluvial‐lacustrine activity from orbital observations
Abstract On February 18, 2021 NASA's Perseverance rover landed in Jezero crater, located
at the northwestern edge of the Isidis basin on Mars. The uppermost surface of the present …

Circumpolar ocean stability on Mars 3 Gy ago
What was the nature of the Late Hesperian climate, warm and wet or cold and dry?
Formulated this way the question leads to an apparent paradox since both options seem …

The fundamental connections between the Solar System and exoplanetary science
Over the past several decades, thousands of planets have been discovered outside our
Solar System. These planets exhibit enormous diversity, and their large numbers provide a …

Global climate and river transport simulations of early Mars around the Noachian and Hesperian boundary
Over the past few decades, numerous geochemical and geological observations of early
Mars have suggested the presence of surface river systems during the late Noachian and …

Precipitation and aridity constraints from paleolakes on early Mars
The ancient climate of Mars remains an enigma despite the abundance of in situ and remote-
sensing data revealing hydrological activity in the past. The crux of this debate—informed by …

The history of global strain and geodynamics on Mars
The tectonic record of Mars is dominated by compressional wrinkle ridges on volcanic
surfaces, and these structures have been widely used as a record of tectonic and …

A mineralogical study of glacial flour from Three Sisters, Oregon: An analog for a cold and icy early Mars
Geomorphic and mineralogical data from the martian surface indicate liquid water was
abundant on the martian surface and near subsurface∼ 3.5 to 4 Gyr ago, but whether early …
