Abstract

Since the 1986 encounter of comet Halley and the 1989 PHOBOS Martian observations, the list of possible molecules in the atmospheres of Mars and comets has been extended to the new observed molecules (formaldehyde and methane) and still non observed chemically related constituents. The chemistry involved differs essentially from terrestrial processes by the absence of rainout and of UV filtering and has commonalities with the earth photochemical smog compositions. The list of molecules -- the targets of future observations are presented together with a priority rating. Both Mars and cometary research stress also the importance of spectra of condensed phases and aerosols, as well as molecular complexes. A list of targets accessible by existing or proposed instruments is shown together with simulations using the 1992 HITRAN data-base together with models.
