Icy Worlds as Astrobiology Laboratories

Ronen Jacovi

NASA Postdoctoral Program (BPP) Fellow

It is for some years now that it is widely accepted that the search for the origin of life is better to concentrate in the icy satellites of the solar system, especially Jupiter's and Saturn's. Triton, the well known and still mysterious satellite of Neptune may also be a good candidate as also be the KBO's themselves. Many observations both ground based and in-situ measurements had proved the ice surfaces of many of those solar-system bodies to have organic molecules implemented in this ice. Those organic molecules, exposed to solar radiation, energetic particles and cosmic rays are under extensive chemistry processes to build the "building blocks" of life and may give us some clues to what had been the origin of life as we
know it.

At the Ice Spectroscopy Laboratory at JPL, there are some on-going studies of organic ices and water ice doped with organics.

I will overview the possible sites for those processes to take place in the solar system and describe briefly the research at JPL.
