| Summary:

Earth, Mars, and Venus, irradiated by an evolving Sun, have had fascinating
but diverging histories of habitability. Although only Earth’s surface is
considered to be habitable today, all three planets might have simultaneously
been habitable early in their histories. We consider how physical processes
that have operated similarly or differently on these planets determined the
creation and evolution of their atmospheres and surfaces over time. These
include the geophysical and geochemical processes that determined the style of
their interior dynamics and the presence or absence of a magnetic field; the
surface-atmosphere exchange processes that acted as a source or sink for
atmospheric mass and composition; the Sun-planet interactions that controlled
escape of gases to space; and the atmospheric processes that interacted with
these to determine climate and habitability. The divergent evolutions of the
three planets provide an invaluable context for thinking about the search for
life outside the Solar System.
