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

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 …

Venus today is inhospitable at the surface, its average temperature of 750 K being
incompatible to the existence of life as we know it. However, the potential for past surface …

This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its
composition by interior/exterior cycling. The formation and evolution of Venus's atmosphere …

Whether Venus was ever habitable is a key question driving missions to Earth's sister planet
in the next decade. Venus today has a dry, O2-poor atmosphere, but recent work has …

Here we examine how our knowledge of present day Venus can inform terrestrial
exoplanetary science and how exoplanetary science can inform our study of Venus. In a …

Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the
atmospheric chemistry. It has been proposed that abundant Venusian life could obtain …

As of mid-2023 at least ten missions are in development or being planned to explore Venus
in the next 2 decades. Most of these emphasize atmospheric chemistry and surface/interior …

The conventional observables to identify a habitable or inhabited environment in
exoplanets, such as an ocean glint or abundant atmospheric O2, will be challenging to …

Context. A major goal in the search for extraterrestrial life is the detection of liquid water on
the surface of exoplanets. On terrestrial planets, volcanic outgassing is a significant source …
