Meteorites are extraterrestrial objects that survive the impact with the Earth's surface. They preserve some of the most primitive materials in the solar system. Therefore meteorites can help us understand the solar system genesis and the processes that occurred once they had accreted into asteroids, the parent bodies for most meteorites. Some meteorites have a rich organic inventory. It is suggested that during the period of heavy bombardment (3.8 to 4.5 Gyrs ago), meteoritic organic matter was exogenously delivered to the early Earth, contributing the first prebiotic building blocks of life to our early planet. In this session we will discuss the chemical, mineralogical and isotopic composition of meteorites. We will also discuss the possible importance of meteoritic organic molecules for the origin and evolution of life on Earth.
