Venus

Morning Starevening starCytherocentric
The surface of Venus is dominated by volcanic features and has more volcanoes than any other planet in the Solar System. However, radar sounding by the Magellan probe revealed evidence for comparatively recent volcanic activity at Venus's highest volcano Maat Mons, in the form of ash flows near the summit and on the northern flank.
Venus's surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.

VERITAS (spacecraft)

VERITASVenus Emissivity, Radio Science, InSAR Topography and Spectroscopy
She has proposed two missions to Venus to elucidate the planet: Venus Origins Explorer (VOX), and VERITAS.
The combination of surface topography and image data would provide knowledge of Venus' tectonic and impact history, the timing and mechanisms of volcanic resurfacing, and the mantle processes responsible for them.

Akatsuki (spacecraft)

AkatsukiAkatsuki (PLANET-C)AKATSUKI probe
The Japanese orbiter Akatsuki is currently searching for visible lightning on Venus, among other science objectives.
Other experiments are designed to confirm the presence of lightning and to determine whether volcanism occurs currently on Venus.

Venus Origins Explorer

VOX
She has proposed two missions to Venus to elucidate the planet: Venus Origins Explorer (VOX), and VERITAS.
Current data are suggestive of recent and active volcanism on Venus, and this mission could determine if current volcanism is limited to mantle plume heads or if more widespread.

Maat Mons

However, radar sounding by the Magellan probe revealed evidence for comparatively recent volcanic activity at Venus's highest volcano Maat Mons, in the form of ash flows near the summit and on the northern flank. Scientists suspect that there are three volcanoes that may be active: Maat Mons, Ozza Mons and Sapas Mons.

Shield volcano

shield volcanoesshieldlava shield
Venus has shield volcanoes, widespread lava flows and some unusual volcanoes called pancake domes and "tick-like" structures which are not present on Earth.
Venus also has over 150 shield volcanoes which are much flatter, with a larger surface area than those found on Earth, some having a diameter of more than 700 km. Although the majority of these are long extinct it has been suggested, from observations by the Venus Express spacecraft, that many may still be active.

EnVision (spacecraft)

EnVision
EnVision would be capable of detecting centimeter-scale surface changes that would enable characterisation of volcanic and tectonic activity, and estimate rates of weathering and surface alteration.

Life on Venus

Carbonyl sulfide is difficult to produce inorganically, but it can be produced by volcanism.

Both VERITAS and DAVINCI were featured prominently in the media during this time, through recent discoveries concerning volcanism on the planet, and a frigid cold layer in Venus atmosphere; both subjects of interest to each respective mission.

It has a surface that is 90% basalt, and about 65% of the planet consists of a mosaic of volcanic lava plains, indicating that volcanism played a major role in shaping its surface.
