Three Experiments in Biological Origins: Early Earth, Venus and Mars January 12 – January 16, 2016
Kuramae Hall, Tokyo Institute of Technology, Tokyo, Japan
Only Earth has generated and maintained a biosphere, which greatly altered the chemical and physical evolution of the planet. Whether Venus and Mars were temporarily able to develop a biosphere of any kind, is largely unknown.
Substantial progress has been made in forming a coherent picture of the early Solar System and planetary formation processes and our understanding of the environmental conditions on young planets. Investigation of initial sets of prebiotic chemical systems has illuminated the origin and early evolution of life. Now all this knowledge will coalesce around the concept of the planetary requisite for prebiotic chemical evolution and origination of life.
To crystallize this knowledge is the goal of this symposium. We summarize the formation and early environment of Venus, Earth and Mars and place them into context relative to each other, and to exoplanets. Why did just Earth succeed?
