Life Sciences and Space Research XXV(4)

Since the development of space technologies and the exploration of the Moon and of our neighbouring planets by use of space vehicles, extraterrestrial biology has become established as a scientific topic. Comets, chondritic meteorites and interplanetary dust of our solar system bear witness to the existence of a dynamic organic chemistry from its earliest stages, during the condensation of the solar nebula. These proceedings containing fifty-six papers feature mainly extraterrestrial organic chemistry and the origins of life; life on Mars; planetary protection for Mars missions, and chemical evolution on Titan.
