Martian organic chemical inventory by analyzing organic-rich carbon phases in meteorites
Short description
The recent discoveries of organic molecules on Mars, which are one of the main building blocks of life, are increasing scientific interest, although their origin - from space, abiotic processes or biological activity on Mars - remains uncertain. This study will provide insights that will not only increase our understanding of Martian organic matter but also guide the development of analytical protocols for future samples retrieved from Mars.
Background
At an early stage, Mars, with its Earth-like conditions, had a denser atmosphere and stable surface water, making it a potentially habitable planet. Discoveries of organic molecules on Mars, which are one of the main building blocks of life, have further increased scientific interest in the question of whether we are alone in the universe. However, the origin of the organic molecules discovered on Mars in recent times is still uncertain. The current knowledge comes mainly from studies of Martian meteorites, the only Martian samples available until the Mars Sample Return mission is completed.
Objectives
The research project explores the Martian organic chemical inventory by analyzing organic carbon-rich phases in meteorites. This is done using advanced mass spectrometry and spectroscopy techniques. The focus is on comparing different organic compositions and their mineral associations with different carbon sources to understand their origins and roles in the Martian carbon cycle.
Results of the study
The results of the study will provide insights that will not only increase our understanding of Martian organic matter but also guide the development of analytical protocols for future samples sent back from Mars.
