Description Abiotic formation of organic molecules Mars rovers have found complex organic molecules in the ancient rocks exposed on the planet’s surface and methane in the modern atmosphere. It is unclear what processes produced these organics, with proposals including both biotic and abiotic sources. Steele et al. analyzed the nanoscale mineralogy of the Mars meteorite ALH 84001 and found evidence of organic synthesis driven by serpentinization and carbonation reactions that occurred during… 

Diagnostic biosignature transformation under simulated martian radiation in organic-rich sedimentary rocks

As we look for traces of ancient life on Mars, we need to consider the impact of ionizing radiation in the biosignature preservation process. Here, we irradiated two organic rich terrestrial samples

Deep-UV Raman Spectroscopy of Carbonaceous Precambrian Microfossils: Insights into the Search for Past Life on Mars.

The current strategy for detecting evidence of ancient life on Mars-a primary goal of NASA's ongoing Mars 2020 mission-is based largely on knowledge of Precambrian life and of its preservation in

Aqueous alteration processes in Jezero crater, Mars-implications for organic geochemistry.

The Perseverance rover landed in Jezero crater, Mars in February 2021. We used the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument to

Serpentinization as a route to liberating phosphorus on habitable worlds

Planetary habitability is in part governed by nutrient availability, including the availability of the element phosphorus. The nutrient phosphorus plays roles in various necessary biochemical

Chirality in Organic and Mineral Systems: A Review of Reactivity and Alteration Processes Relevant to Prebiotic Chemistry and Life Detection Missions

The properties oforganic compounds and minerals as well as the physical, chemical, and geological processes that affect organic and mineral chirality during the preservation and detection of organic compounds are reviewed.

Accessing the Habitability of the Martian Surface and Subsurface Based on Analogs Found on Earth

  • Geology, Physics
  • 2022
So far, the only life we know of is on Earth, but the search for life on other planetary bodies is still ongoing. Mars is particularly interesting, mainly because it is more practical to study

In response to our reporting the carbon isotopic composi-tions of CH 4 released during pyrolysis of solid Mars sediments (1), Schoell (2) states that our full dataset does not follow a trend with

Alteration history of Séítah formation rocks inferred by PIXL x-ray fluorescence, x-ray diffraction, and multispectral imaging on Mars

Collocated crystal sizes and mineral identities are critical for interpreting textural relationships in rocks and testing geological hypotheses, but it has been previously impossible to unambiguously

Compositionally and density stratified igneous terrain in Jezero crater, Mars

Before Perseverance, Jezero crater’s floor was variably hypothesized to have a lacustrine, lava, volcanic airfall, or aeolian origin. SuperCam observations in the first 286 Mars days on Mars revealed

The SHERLOC Calibration Target on the Mars 2020 Perseverance Rover: Design, Operations, Outreach, and Future Human Exploration Functions

The Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is a robotic arm-mounted instrument onboard NASA’s Perseverance rover. SHERLOC combines imaging

A Reduced Organic Carbon Component in Martian Basalts

Measurements of organic material in 11 martian meteorites, including the Tissint meteorite, are presented, implying that the organics formed as the magma melt crystallized and are thus of abiotic origin.

In-situ preservation of nitrogen-bearing organics in Noachian Martian carbonates

A new technique is employed to assess organic nitrogen compounds in a Martian meteorite, concluding that these compounds are indeed likely to originate from the Red Planet.

Organic synthesis on Mars by electrochemical reduction of CO2

It is shown that martian meteorites Tissint, Nakhla, and NWA 1950 have an inventory of organic carbon species associated with fluid-mineral reactions that are remarkably consistent with those detected by the Mars Science Laboratory (MSL) mission.

Organic matter preserved in 3-billion-year-old mudstones at Gale crater, Mars

In situ detection of organic matter preserved in lacustrine mudstones at the base of the ~3.5-billion-year-old Murray formation at Pahrump Hills, Gale crater, by the Sample Analysis at Mars instrument suite onboard the Curiosity rover is reported.

Coupled organic synthesis and mineral alteration on meteorite parent bodies

Abstract— The hypothesis that the soluble fraction of the organic compounds present in carbonaceous chondrite meteorites was formed during aqueous alteration of the parent body was tested with

Abiogenic formation of alkanes in the Earth's crust as a minor source for global hydrocarbon reservoirs

The progressive isotopic trends for the series of C1–C4 alkanes indicate that hydrocarbon formation occurs by way of polymerization of methane precursors, and it can now be rule out the presence of a globally significant abiogenic source of hydrocarbons.

Search for Past Life on Mars: Possible Relic Biogenic Activity in Martian Meteorite ALH84001

High-resolution scanning and transmission electron microscopy study of surface textures and internal structures of selected carbonate globules show that the globules contain fine-grained, secondary phases of single-domain magnetite and iron sulfides.

Sequestration of Martian CO2 by mineral carbonation

Electron beam imaging and analysis show that olivine and a plagioclase feldspar-rich mesostasis in the Lafayette meteorite have been replaced by carbonate, the first direct evidence for CO2 sequestration and storage on Mars by mineral carbonation.

Reduction of nitrogen compounds in oceanic basement and its implications for HCN formation and abiotic organic synthesis

Convergent margins in the initial phase of subduction must be considered the most potent sites for prebiotic reactions on Earth, which means that origin of life processes are, perhaps, only possible on planets where some kind of plate tectonics occur.

Carbonates in the Martian meteorite Allan Hills 84001 formed at 18 ± 4 °C in a near-surface aqueous environment

The precipitation temperature of secondary carbonate minerals preserved in the oldest known sample of Mars’ crust is determined, finding that the carbonates in ALH84001 precipitated at a temperature of approximately 18 °C, with water and carbon dioxide derived from the ancient Martian atmosphere.
