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

More than three decades have passed since the publication of the last review of the Venus
clouds and hazes. The paper published in 1983 in the Venus book summarized the …

The habitability of the surface of any planet is determined by a complex evolution of its
interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive …

The current goals of the astrobiology community are focused on develo** a framework for
the detection of biosignatures, or evidence thereof, on objects inside and outside of our solar …

At least some of Venus' lava flows are thought to be< 2.5 million years old based on visible
to near-infrared (VNIR) emissivity measured by the Venus Express spacecraft. However, the …

The depletion of SO 2 and H 2 O in and above the clouds of Venus (45–65 km) cannot be
explained by known gas-phase chemistry and the observed composition of the atmosphere …

Aims. Following the announcement of the detection of phosphine (PH 3) in the cloud deck of
Venus at millimeter wavelengths, we searched for other possible signatures of this molecule …

New observations from the Venus Express spacecraft as well as theoretical and
experimental investigation of Venus analogue materials have advanced our understanding …

This work reviews possible signatures and potential detectability of present-day volcanically
emitted material in the atmosphere of Venus. We first discuss the expected composition of …

We observed Venus with the Apache Point Observatory 3.5 m telescope TripleSpec
spectrograph (R= 3500, λ= 0.96–2.47 µm) on 1–3 March 2009 and on 25, 27, and 30 …
