EnVision

EnVision [ESA]

EnVision is an ESA Venus orbiter, providing a holistic view of the planet from its inner core to upper atmosphere to determine how and why Venus and Earth evolved so differently.

EnVision will be equipped with a suite of European instruments including a sounder to reveal underground layering, and spectrometers to study the atmosphere and surface. The spectrometers will monitor trace gases in the atmosphere and analyse surface composition, looking for any changes that might be linked to signs of active volcanism. A NASA-provided radar will image and map the surface. In addition, a radio science experiment will probe the planet’s internal structure and gravity field as well as investigate the structure and composition of the atmosphere. The instruments will work together to best characterise the interaction between the planet’s different boundaries – from the interior to surface to atmosphere – providing an all-encompassing global view of the planet and its processes.
