ESA's Envision Venus Mission Proceeds Without NASA Radar Instrument
Key points
- ESA's Envision mission will proceed without NASA's radar instrument.
- NASA withdrew due to budget cuts affecting international partnerships.
- Envision aims to map Venus's surface at high resolution.
- The mission will use radar to detect active volcanism.
ESA Continues Envision Mission
The European Space Agency (ESA) announced it is moving forward with its Envision mission to Venus. This decision follows NASA's determination that it could not fulfill its commitment to provide a US-built radar instrument for the spacecraft.
Mission Objectives
Envision is designed to map the Venusian surface with 10 times higher resolution than previous radar missions. Venus's surface is obscured by thick sulfuric acid clouds, making radar essential for observation. Scientists plan to use Envision to search for signs of active volcanism on the planet.
Original Partnership Details
A 2024 memorandum of understanding between NASA and ESA outlined their partnership. NASA was to supply a synthetic aperture radar instrument, the primary tool for mapping Venus, along with tracking and communications support. In return, ESA would include US researchers on the science team, build the spacecraft and other instruments, and provide the launch via an Ariane 6 rocket.
NASA's Budgetary Constraints
NASA's withdrawal stems from budget pressures. The agency's science funding faced proposed cuts, and while Congress rejected most of these, the planetary science division received less funding than the previous year. This shortfall forced NASA to prioritize, leading to cuts in support for international mission partnerships.

Reporting from
The European Space Agency (ESA) will continue its Envision mission to Venus independently after NASA withdrew its commitment to provide a key radar instrument. This change occurred due to NASA's budget constraints, which necessitated cuts to international mission partnerships.
