The European Space Agency (ESA) is still in the dark about NASA's participation in its Venus exploration mission Envision despite the project's tight deadline, ESA representatives said in a recent media briefing.
Envision, which began construction in 2025, will map the atmosphere and geology of Earth's closest neighbor, the fiery Venus. The spacecraft will rely on a NASA-made instrument called VenSar — a novel synthetic aperture radar — to map the planet's surface in three dimensions and with a resolution of up to 3 feet (10 meters).
