Observations from orbital spacecraft have shown that Jezero crater on Mars contains a
prominent fan-shaped body of sedimentary rock deposited at its western margin. The …

Jezero crater has been selected as the landing site for the Mars 2020 Perseverance rover,
because it contains a paleolake with two fan-deltas, inlet and outlet valleys. Using the data …

Early observations from the Perseverance rover suggested a deltaic origin for the western
fan of Jezero crater only from images of the Kodiak butte. Here, we use images from the …

Alluvial rivers are conveyor belts of fluid and sediment that provide a record of upstream
climate and erosion on Earth, Titan, and Mars. However, many of Earth's rivers remain …

Although there is little doubt that rivers once flowed on Mars' surface, how sustained and
frequent their flows were remains enigmatic. Understanding the hydrology of early Mars …

As Mars transitioned from an early Earth-like state to the cold desert planet it is today, it
preserved a near pristine record of surface environments in a world without plate tectonics …

Flume experiments and field observations show that bank vegetation promotes the formation
of narrow and deep single‐thread channels by strengthening riverbanks. Consistent with …

There is abundant evidence from fluvial landforms and deposits that Mars had rivers that
actively transported sediment and shaped its surface. Sediment transport equations are …

Recent surface observations have emphasised the importance of bedload transport by rivers
and streams on Mars and Titan. Previous “hydraulic” analysis, however, has also shown that …

Relatively pristine valley segments along medial-to-distal Samara Valles in Margaritifer
Terra likely originate within the continuous ejecta west of the Late-Hesperian Jones impact …
