In this work we discuss various selected mission concepts addressing Venus evolution
through time. More specifically, we address investigations and payload instrument concepts …

Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

Abstract The Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging
(DAVINCI) mission described herein has been selected for flight to Venus as part of the …

Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5–3.8
billion years ago. However, it is still unknown whether water has ever condensed on the …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

The dynamics and evolution of Venus' mantle are of first-order relevance for the origin and
modification of the tectonic and volcanic structures we observe on Venus today. Solid-state …

Mildly irradiated mini-Neptunes have densities potentially consistent with them hosting
substantial liquid-water oceans (" Hycean" planets). The presence of CO 2 and …

Abstract The Great Dyke of Atla Regio (GDAR) is traced for~ 3700 km on Venus, as a
surface graben (narrow trough) interpreted to overlie a continuous laterally-emplaced …

The flood basalts of large igneous provinces (LIPs) are fed by a vast and often complicated
plumbing system that can include giant dyke swarms, sill complexes, mid-to upper-crustal …

Understanding the set of conditions that allow rocky planets to have liquid water on their
surface, in the form of lakes, seas, or oceans, is a major scientific step in determining the …
