Then there were 3: NASA to collaborate on ESA's new Venus mission

On June 10, 2021, the European Space Agency (ESA) announced the selection of EnVision as its newest medium-class science mission. EnVision will make detailed observations of Venus to understand its history and especially understand the connections between the atmosphere and geologic processes. As a key partner in the mission, NASA provides the synthetic aperture radar, called VenSAR, to make high-resolution measurements of the planet's surface features.
