Welcome to ESA's EnVision mission science and technical pages
EnVision will be ESA’s next 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 was selected as ESA’s 5th Medium-class mission in the Agency’s Cosmic Vision plan, targeting a launch in early 2030s (current working assumption: end 2031). The mission adoption is scheduled for January/February 2024.
The objective of EnVision is to observe the planet from its inner core up to its upper atmosphere, studying the planet's history, activity and climate. This will be achieved by its five instruments, provided by European and US research institutes and space agencies. EnVision aims to characterize Venus’ core and mantle structure, to detect signs of past geologic processes, and to look for evidence of past liquid water. Recent modelling studies strongly suggest that the evolution of the atmosphere and interior of Venus are coupled, emphasizing the need to study the atmosphere, surface, and interior of Venus as a system.
ESA led mission in partnership with NASA
EnVision is an ESA led mission in partnership with NASA, with NASA providing the Synthetic Aperture Radar (VenSAR) and Deep Space Network support for critical mission phases.
The ESA Study and Project Teams are located in ESA's centre ESTEC (Noordwijk, The Netherlands). The launch and operations will be supported by the Mission Operations Centre (MOC) at ESA's centre ESOC (Darmstadt, Germany) and the science operations and data archiving by the Science Operations Centre (SOC) and Planetary Science Archive (PSA) at ESA's centre ESAC (Madrid, Spain). The instrument operations and operational interfaces to the SOC is distributed across the Instrument Teams.
EnVision VenSAR is part of NASA's Discovery Program. NASA's Marshall Space Flight Centre in Huntsville, Alabama, manages the Discovery Program for NASA's Science Mission Directorate in Washington D.C. The Jet Propultion Laboratory (JPL), a division of Caltech in Pasadena, California, will provide the VenSAR radar, and will have responsibility over the overall instrument management and provision.
Contributions by ESA member states
ASI, DLR, BelSPO, RIU and CNES will lead the procurements of the SRS, VenSpec-M, VenSpec-H and VenSpec-U instruments and the Radio Science Experiment (RSE), respectively.
