Spatially distributed complex organic matter detected in an ancient river valley in Jezero crater, Mars

Ashley Murphy, Kyle Uckert, K. P. Hand, R. Bhartia et autres

Using a Raman spectrometer onboard the Perseverance rover, we report the heterogeneous distribution of organic carbon within mudstones located in an ancient river valley on Mars. Measurements of two mudstones show hundreds of organic detections, making this the most robust organic detection …

Intrusion‐Induced Forced Folding Model for the Origin of Séítah Formation Domes on the Jezero Crater Floor, Mars

Robert Barnes, Sanjeev Gupta, A. H. Treiman, Steven Sholes et autres

Abstract The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating …

Carbonated ultramafic igneous rocks in Jezero crater, Mars

Kenneth H. Williford, Kenneth A. Farley, B. Horgan, Bradley Garczynski et autres

The Perseverance rover landed in Jezero crater on Mars, which once contained a lake of liquid water. We report the rock properties encountered by Perseverance during a 10-kilometer traverse extending over 400 meters in elevation, from beneath Jezero's western sedimentary fan to …

Abrasion Patch Dehydration Experiment at Bright Angel, Jezero Crater, Using SuperCam Onboard the Mars 2020 Perseverance Rover

Stephanie Connell, R. C. Wiens, Lucia Mandon, C. C. Bedford et autres

Abstract Investigating the stability of hydrated minerals is integral for examining the preservation of rocks for potential Mars Sample Return and has major implications for models that use rover‐based observations to quantify Mars' global water budget. The Mars 2020 Perseverance rover produces …

Sedimentology and stratigraphy of the fluvial–deltaic Skrinkle Haven member, Tenby formation, Jezero Crater, Mars

Libby R. W. Ives, K. M. Stack, Emily Geyman, Sanjeev Gupta et autres

ABSTRACT In 2023, the Mars 2020 Perseverance rover investigated the Skrinkle Haven member of the Tenby formation in the > 3.5-billion-year Jezero Crater western fan. This unit was interpreted from orbiter data as bank attached, lateral-accretion bars in a sinuous river on …

Redox-driven mineral and organic associations in Jezero Crater, Mars

J. A. Hurowitz, Michael M. Tice, Abigail C. Allwood, Morgan L. Cable et autres

The Perseverance rover has explored and sampled igneous and sedimentary rocks within Jezero Crater to characterize early Martian geological processes and habitability and search for potential biosignatures1–7. Upon entering Neretva Vallis, on Jezero Crater’s western edge8, Perseverance investigated distinctive mudstone and conglomerate …

A fluvio-lacustrine environment preserved in the Jezero crater inlet channel, Neretva Vallis (Mars)

Alexander Jones, Robert Barnes, Sanjeev Gupta, Gerhard Paar et autres

Introduction: Fluvial valley networks on Mars provide key sites for investigating the role of surface liquid water in Mars’ ancient past. Between June and August 2024, the Perseverance rover spent 85 sols exploring a series of outcrops in Neretva Vallis, one of …

Pre-impact stratigraphy exposed in the western Jezero crater rim

Robert Barnes, Alexander Jones, Sanjeev Gupta, Gerhard Paar et autres

The NASA rover Perseverance traversed down the western slopes of the Jezero crater rim, informally named Witch Hazel Hill, between sols 1358 to 1500+, providing an opportunity to observe and analyse a relatively pristine, though ancient, 45 km-wide Noachian impact crater. The …

Simulating Science Operations for a Joint Rover-helicopter Mission Architecture in a Mars Analog Setting

K. M. Stack, Raymond Francis, Fred J. Calef, Samantha Gwizd et autres

Abstract Aerial platforms can explore planetary surfaces without the mobility limitations of rovers and landers. Inspired by the recent successes and challenges of NASA’s IngenuAity Mars Helicopter, the Rover-Aerial Vehicle Exploration Network project explored the operations and science value of a dual-platform …
