One key element in searching for life on Mars is the presence of methane in the Martian atmosphere As a simple carbon compound, methane is often a precursor to the formation of the complex organic chemicals that make life possible.

The calculations indicate that the formation of longer chain hydrocarbons can happen in pure methane but the process is accelerated when the methane molecules are in contact with metal or carbon surfaces, e.g. diamond which act as catalysts for the methane-polymerisation to occur.
