Thermodynamic conditions suggest that clathrates might exist on Mars. Despite
observations which show that the dominant condensed phases on the surface of Mars are …

Spectral observations have detected methane within the martian atmosphere (Formisano,
V., Atreya, S., Encrenaz, T., Ignatiev, N., Giuranna, M.[2004]. Science 306, 1758–1761; …

The biosignatures of life on Earth do not remain static, but change considerably over the
planet's habitable lifetime. Earth's future biosphere, much like that of the early Earth, will …

We calculate transport timescales of martian methane and investigate the effect of potential
release mechanisms into the atmosphere using a numerical model that includes both …

Methane hydrate dissociation due to obliquity-driven temperature change has been
suggested as a potential source of atmospheric methane plumes recently observed on Mars …

Many processes on Mars have yet to be understood, and the series of methane (CH4)
detection and non-detection in the atmosphere of the planet over the last two decades has …

Diffusivity and solubility of gas molecules in crystalline water ice are fundamental
physicochemical parameters that could play key roles in various environments in space, icy …

Life on Mars, if present, is suggested to exist only in the subsurface as the surface conditions
are extremely oxidizing for known life forms to survive. Past knowledge from meteorites and …

The stable isotopic composition of carbon (δ 13 C CH 4) and hydrogen (δ 2 H CH 4) in
methane and sulfur (δ 34 SH 2 S) in hydrogen sulfide can be used to infer the source of …

Is there life beyond Earth or are we alone in the universe? This question has intrigued
humankind for thousands of years, but all attempts to find answers have remained largely in …
