Exobiology in Earth orbit [PDF]

open access: bronzeOrigins of life and evolution of the biosphere, 1996
The primary goal of exobiological research is to reach a better understanding of the processes leading to the origin, evolution and distribution of life on Earth or elsewhere in the universe. In this endeavor, scientists from a wide variety of disciplines are involved, such as astronomy, planetary research, organic chemistry, paleontology and the ...
