The Sixth Trieste Conference on Chemical Evolution for the first time has also been a Euroconference. This year we focused on "First Steps in the Origin of Life in the Universe". (Both this Centre and the ICGEB have been sponsors since we first started planning the series with Professors Abdus Salam and Cyril Ponnamperuma. ) The conference had the following 11 sponsors: The Abdus Salam International Centre for Theoretical Physics, The European Commission, The SETI Institute, Consiglio Nazionale delle Ricerche, Rome, Italy, The International Centre for Genetic Engineering and Biotechnology, Trieste, The European Space Agency (ESA), National Aeronautics and Space Administration (NASA) Universite Paris 12, The ICTP Public Information Office, La Fondazione Internazionale Trieste per il Progresso e la Liberta della Scienza, and II Laboratorio dell'Immaginario Scientifico. of our Over 90 participants allowed us to make a truly comprehensive review subject. In 82 presentations we had contributions from experts in questions related to the origin, evolution, distribution and destiny of life in the universe, topics that are known together as the science ofastrobiology.The publication ofthese proceedings was largely due to a generous grant form the Consiglio Nazionale delle Ricerche, Rome, Italy. The general topic of the conference concerned the origin, evolution, distribution and destiny of life in the Universe, a subject referred to as astrobiology and also as exobiology. In this report we prefer the synonym Astrobiology.

This volume, number 16 in the Space Sciences Series of ISSI, reviews the present knowledgeonmanyaspectsofthehistoryofthesolarsystem. Itfocuses onisotopic signatures ofvolatile elements as tracers for the evolutionary processes during the formation of the Sun and the planets from an interstellar molecular cloud and, in tum, illuminates how the isotopic compositions of present-day solar system ob- jects had been established. This integrated collection of articles complements the information provided by previous ISSI volumes such as From Dust to Terrestrial Planets and Chronology and Evolution of Mars, expanding the time scale for the history ofthe solar system. The convenors, Therese Encrenaz, Observatoire de Paris, Meudon; Johannes Geiss, ISSI, Bern; Reinald Kallenbach, ISSI, Bern; Konrad Mauersberger, Max- Planck-Institut fUr Kernphysik, Heidelberg; Tobias Owen, University of Hawaii, Honolulu; and Fran~ois Robert, CNRS-Museum d'Histoire Naturelle, Paris, in- vited experts in planetary science, solar and heliospheric physics, astrophysics, mineralogy, and chemistry to an interdisciplinary workshop in Bern, 14-18 Jan- uary 2002.The resulting review articles are grouped into four sections 'Sun and Protosolar Nebula', 'Outer Solar System', 'Earth, Terrestrial Planets, and Moon', and 'Isotopic FractionationProcesses'.

IAU Symposium 40, on Planetary Atmospheres, was held at Marfa, Texas, in the Paisano Hotel, October 26-31, 1969, hosted by The University of Texas at Austin and the McDonald Observatory of the University of Texas. The Organizing Committee consisted of: Dr. Tobias Owen (Illinois Institute of Technology), Dr. Carl Sagan (Cornell University), Dr. John Hall (Lowell Observa- tory), Dr. Arvydas Kliore (Jet Propulsion Laboratory), Academician Georgi I. Petrov (Institute of Cosmic Research, Soviet Academy of Sciences), Dr. V. I. Moroz (Stern- berg Institute), Dr. H. C. van de Hulst (Leiden University). Local arrangements were under the care of Dr. Harlan Smith (McDonald Observa- tory), assisted especially by Dr. Ronald Schorn (Jet Propulsion Laboratory), Mr. Curtis Laughlin (McDonald Observatory), and Miss Virginia Church (University of Texas); also by Dr. Joseph Chamberlain (Kitt Peak National Observatory), Dr. Maurice Marin (McDonald Observatory), Mr. and Mrs. J. Bergstrahl and Mrs. K. MacFarlane (McDonald Observatory), and Dr. Donald Rea (NASA Headquarters). The scientific program was divided into three parts; Venus, Mars, and the outer planets.Detailed programs for these sections, and their subsequent editing, were respectively in the hands of the undersigned. It was possible to hold the Symposium because of generous sponsorship by the Executive Committee of the International Astronomical Union, including the provi- sion of a travel grant for assisting younger astronomers to attend, and also including the active attention and assistance of the Assistant General Secretary, Dr. C. de Jager.
