Original Abstract
The exploration of planetary atmosphere is being advanced by the exciting results of the Cassini-Huygens mission to Saturn and Titan, its most famous moon. The complex chemistry revealed in such atmospheres leading to the synthesis of bigger molecules is providing new insights into our understanding of how life on Earth developed. In our experiments Titan's atmosphere is simulated in a glow-discharge formed from a mixture of CH4-N2 gas. Samples of the discharge gas were analysed by Fourier Transform Infrared Spectroscopy. Measurements revealed HCN and NH3 to be the major products of the plasma with traces of C2H2. Carbon monoxide and water were detected as reaction products in methane-nitrogen gas mixture with 1% of carbon dioxide. These molecules could be precursors for other more complicated molecular structures, even some amino acids.
