We are not only interested in the origin of volatile elements on Earth but also aim to constrain how the processes of accretion and early differentiation might have shaped the starting condition for other rocky bodies in our Solar System and other solar systems. Through the CLEVER Planets’ interdisciplinary research, we are combining our expertise with cosmochemistry, astrophysics, astrochemistry, geodynamics, and geophysical modeling. A lot of our current work in the realm of planetary science also involves active collaboration with various members of the CLEVER Planets research program. Is it owing to accretion from vastly different compositions, or is it because of the difference in conditions of early evolution (e.g., thermal and oxidation state and depth of core-mantle separation) that caused very different fractionation of fluids between the interior and the exosphere? Our goal is to compare and contrast the origin and cycling of volatiles and fluids, thermal and magmatic history of various known and plausible rocky planets through time. We do not know why these planets have drastically different atmosphere. To understand how Earth distinguished itself as the only known inhabited planet among the Solar System bodies, there are lessons to be learnt from geologic evolution of other terrestrial planetary bodies, such as Mars, the Moon, Venus, and Mercury and even exoplanets (planets around other stars in our galaxy and beyond).
