Mumma et al. 1 have confirmed earlier detections of methane in the Martian atmosphere, finding it localized and correlated with atmospheric water vapor. They determined that, because of the short half-life of methane, a continual replenishment is required to account for its presence. They also conclude that the dynamics of methane on Mars require a methane sink in the soil. It is suggested here that both phenomenon could be accounted for by an ecology of methane-producing and methane-consuming… 

Likelihood of methane-producing microbes on Mars

We present a likelihood estimate that methane was a significant component of the gas detected by the Labeled Release (LR) experiment in the Viking Mission to Mars of 1976. In comparison with

Mars microbes may make methane: the Viking view

These findings suggest that methane, in addition to CO2, was evolved in the LR experiment, and the necessary size of the microbial population and the amount of water necessary to maintain that population in an aqueous state is estimated.

The Effects of Perchlorates on the Permafrost Methanogens: Implication for Autotrophic Life on Mars

A biochemical understanding of these pathways is expected to provide a basis for designing experiments to detect autotrophic methane-producing life forms on Mars, and evidence that permafrost hydogenotrophic methanogens are more resistant to the chaotropic agent found in Martian soil is presented.

The Apparent Involvement of ANMEs in Mineral Dependent Methane Oxidation, as an Analog for Possible Martian Methanotrophy

Results suggest that the microorganisms found active in the manganese-dependent incubations are likely capable of sulfate-dependent AOM, and similar metabolic flexibility for Martian methanotrophs would mean that the same microbial groups could inhabit a diverse set of Martian mineralogical crustal environments.

Comments on the June 7, 2018, NASA News Release and Papers.

The June 7, 2018, NASA news conference and two related papers in Science regarding the findings of organic molecules (Eigenbrode et al., 2018) and methane (Webster et al., 2018) on Mars are exciting

Preservation of Methanogenic Cultures to Enhance Anaerobic Digestion

Dried methanogenic cultures were found to be viable options to use as a bioaugment to improve treatment efficiency of anaerobic digesters after toxic upset and for the BMP assay.

Complexity Analysis of the Viking Labeled Release Experiments

The complexity pattern seen in active experiments strongly suggests biology while the different pattern in the control responses is more likely to be non-biological, support the interpretation that the Viking LR experiment did detect extant microbial life on Mars.

The big question of the origin of life is examined. The paradox created by Pasteur’s resounding edict: Life only comes from life, pitted against the need for spontaneous generation is explored. This

Mission to Europa for both Manned and Unmanned Exploration Today

This article is a set of well-organized plan formulated for a mission to Europa, which holds promise of water. The plan was deduced upon careful examination of Europa’s topography, in-situ data for

Microbial origin of excess methane in glacial ice and implications for life on Mars.

Equating the loss rate of methane recently discovered in the Martian atmosphere to the production rate by possible methanogens, it is estimated that a possible Martian habitat would be at a temperature of approximately 0 degrees C and that the concentration, if uniformly distributed in a 10-m-thick layer, would be approximately 1 cell per ml.

Methane Production and Oxidation in Soils and Sediments

Methane is the major end-product of anaerobic organic matter degradation in the biosphere. Its importance as a radiatively active trace gas in the atmosphere, increasing at about 1% y-1, has focussed

Facultative Methanotrophs Revisited

This issue of the Journal of Bacteriology, Dedysh and colleagues provide the first unequivocal proof of a genus of methanotrophic bacteria (Methylocella) that are capable of growth on a number of multicarbon substrates, dispelling the notion that meethanotrophy is an obligate phenomenon.

Strong Release of Methane on Mars in Northern Summer 2003

Using high-dispersion infrared spectrometers at three ground-based telescopes, methane and water vapor were measured simultaneously on Mars over several longitude intervals in northern early and late summer in 2003 and near the vernal equinox in 2006.

Mauna Loa volcano is not a methane source: Implications for Mars

Thirteen years of continuous atmospheric carbon dioxide and methane measurements at the Mauna Loa Observatory in Hawaii are used to determine the methane emission rate from the summit of Mauna Loa

The composition of the atmosphere at the surface of Mars

We have confirmed the discovery of N2 and 40Ar by the Entry Science Team, and we have also detected Ne, Kr, Xe, and the primordial isotopes of Ar. The noble gases exhibit an abundance pattern similar

Detection of Methane in the Atmosphere of Mars

We report a detection of methane in the martian atmosphere by the Planetary Fourier Spectrometer onboard the Mars Express spacecraft. The global average methane mixing ratio is found to be 10 ± 5

A new constraint on the antiquity of anaerobic oxidation of methane: Late Pennsylvanian seep limestones from southern Namibia

Late Pennsylvanian seep limestones (ca. 300 Ma) enclosed in the Ganigobis shales in southern Namibia formed by microbial activity. The process that induced carbonate precipitation was the anaerobic
