Cometary nuclei contain the least modified material from the formative epoch of our
planetary system, and their compositions reflect a range of processes experienced by …

Water is a fundamental molecule in the universe. On Earth, water exists in all three phases:
gas, liquid, and solid (ice). Liquid water facilitates many chemical reactions as a solvent …

Context. The ESA Rosetta spacecraft (S/C) is tracking comet 67P/Churyumov-Gerasimenko
in close vicinity. This prolonged encounter enables studying the evolution of the volatile …

Since we intend to review experimental and theoretical studies of physicochemical
processes occurring on cosmic dust grains in very cold regions in space, we start with a brief …

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 …

Using the Fourier Transform Spectrometer at the Canada–France–Hawaii Telescope, we
observed a spectrum of Mars at the P-branch of the strongest CH4 band at 3.3 μm with …

The composition of cometary ices provides key information on the chemical and physical
properties of the outer solar nebula where comets formed, 4.6 Gy ago. This chapter …

We have analyzed data recorded by the Composite Infrared Spectrometer (CIRS) aboard
the Cassini spacecraft during the Titan flybys T0–T10 (July 2004–January 2006). The …

A systematic analysis of the mixing ratios with respect to H 2 O for eight species (CH 3 OH,
HCN, NH 3, H 2 CO, C 2 H 2, C 2 H 6, CH 4, and CO) measured with high-resolution infrared …

One of the most puzzling aspects of Mars is that organics have not yet been found on the
surface. The simplest of organic molecules, methane, was detected in the Martian …
