Earth and Mars — Distinct Inner Solar System Products
Terrestrial planets provide Solar System insights into the evolution of accretion, core-mantle and crust-mantle differentiation, and surface processes. The Earth and Mars have equal enrichment in refractory elements (1.9 × […]

Perspectives On Atmospheric Evolution From Noble Gas And Nitrogen Isotopes On Earth, Mars And Venus
The composition of an atmosphere has integrated the geological history of the entire planetary body. However, the long-term evolutions of the atmospheres of the terrestrial planets are not well documented. […]

Webinar: Redefining "Earth-Like": Habitable Planet Composition and the Case for Moving Beyond the Mass-Radius Diagram
The Earth is more than a one Earth-mass, one Earth-radius, one Earth-density planet. It is the only known terrestrial planet to undergo plate tectonics, have continental crust and a strong […]

Water May Have Appeared While Earth Was Still Growing
Up until about ten years ago, scientists thought they had a pretty good picture of how the moon and Earth came to co-exist. Then more precise measurements blew it all […]
