What has EnVision achieved, what is the path forward?
- The EnVision team and its supporters have already achieved a significant amount of work.
The first team was assembled in 2010 and the first design studies were submitted for ESA review at the M3 proposal opportunity. In 2015, a significantly improved proposal was submitted to ESA for the M4 opportunity. (available at the Resources page). The M4 proposal was not selected but received very contructive technical and scientific feedback from ESA reviewers. Taking it into account has been the prime focus of the envision team since then, readying for the M5 opportunity.
The core team currently assembled is confident and brings balanced diversity to the table. The system’s design has evolved to focus on specific targets and nurture synergistic technical solutions. Collaboration with Airbus Defence and Space (Space Systems) led to the development of a modified version of their NovaSAR‐S radar payload called VenSAR, which offers greater capability for reduced mass and cost. EnVision now also features a streamlined instrument suite, significantly enhanced communications, and a revised mission profile, developed with support of the whole Venus science community and many in the Earth Observation community.
- The official Letter of Intent for the M5 call was submitted to ESA on June 6th 2016
- EnVision then attended the briefing meeting at ESTEC headquarters on June 24th.
- Our next milestone is the official submission of the proposal to ESA on October 5th 2016. This calls for a 50 page document outlining all the aspects of the mission: its science case, mission profile, payload configuration, system level requirements and main risks, programmatic structure and costs analysis and plans for communication and public outreach.
A list of the supporters who endorse the proposal is another important aspect, demonstrating to ESA the significance of the mission to the Venus community, the Earth Observation community, scientists, engineers, faculty, professionals and enthusiasts. We will include their names and affiliation as annex to the proposal.

- In June 2017, up to 4 proposals will be selected for phase A studies. These will be the proposals that are able to accurately demonstrate technical feasibility and first class scientific interest for a total cost to ESA of less than 550 million Euros.
- Launch in 2029. If selected, EnVision will commence detailed design studies, and be ready for launch. Arrival at Venus would then mark the start of a 3 year science operations phase. The data will be continuously acquired and archived through ESA ESTRACK ground stations. Science interpretation and the first results will happen on the fly. The discoveries made day after day will continuously feed into the planning of mission operations.
- A 2 year extended mission operation phase will be considered if the spacecraft remains healthy. This will allow for additional coverage at the highest resolution and a better monitoring of long term evolution of transient features.
- When fuel runs out, the spacecraft’s orbit will naturally decay until the EnVision burns up in the Venusian atmosphere.
