Organic Matter Detection on Mars by Pyrolysis-FTIR: An Analysis of Sensitivity and Mineral Matrix Effects
Returning samples from Mars will require an effective method to assess and select the highest-priority geological materials. The ideal instrument for sample triage would be simple in operation, limited in its demand for resources, and rich in produced diagnostic information. Pyrolysis-Fourier infrared spectroscopy (pyrolysis-FTIR) is a potentially attractive triage instrument that considers bot...
متن کاملThe past and future habitability of planet Mars
Red planet: Mars is tantalisingly Earth-like in many respects, but took a different turn when it lost much of its atmosphere early on. Five space probes are currently active in its exploration. (Photo: NASA/JPL.) Life on Mars was considered almost a certainty at various points in the chequered history of our curiosity about the fourth rock from the Sun. The romantic hope for a second biosphere ...
متن کاملHabitability on Mars from a microbial point of view.
Extraterrestrial habitability is a complex notion. We briefly review what is known about the origin of life on Earth, that is, life based on carbon chemistry and water. We then discuss habitable conditions (past and present) for established life and for the survival of microorganisms. Based on these elements, we propose to use the term habitable only for conditions necessary for the origin of l...
متن کاملDetecting pyrolysis products from bacteria on Mars
A pyrolysis/sublimation technique was developed to isolate volatile amine compounds from a Mars soil analogue inoculated with V10 billion Escherichia coli cells. In this technique, the inoculated soil is heated to 5003C for several seconds at Martian ambient pressure and the sublimate, collected by a cold finger, then analyzed using high performance liquid chromatography. Methylamine and ethyla...
