Jun 10, 2021 · Following the design phase, a European industrial contractor will be selected to build and test Envision, which is foreseen to launch on an Ariane 6 rocket. The earliest launch opportunity for Envision is 2031, with other possible options in 2032 and 2033.
Jan 28, 2024 · ESA also announced Ariane 6 will be the launch vehicle that will transport EnVision. The infamous rocket has been plagued with delays and setbacks for years. However, its recent testing regime has yielded some success .

The spacecraft will be a roughly rectangular three-axis stabilised satellite, weighing approximately 4.1 tonnes at launch (1.7 tonnes dry mass), measuring approx. 2 m x 2 m x 3 m in stowed configuration, with two deployable solar arrays. It will have a power budget of around 3 kW and a large volume (200 Tbits) of science data to be downlinked to Ea...
The EnVision launch is scheduled for November 2031, with back-up dates in 2032 and 2033. The mission will launch with an Ariane 64 rocket (direct escape). The interplanetary cruise phase will take around 15 months. The Venus orbit insertion will be highly elliptic, and the final science orbit will be reached by means of Aerobraking. The Aerobraking...
The science data downlink capability is ~200 Tbits using Ka-/X-band comms system with a >2.5 m diameter fixed high-gain antenna.
The spacecraft orbit will be polar, with a duration of ~92 minutes and an inclination between 87o and 89o. The orbit will be elliptical, with spacecraft altitudes varying between ~220 and 510 km above the surface. The slow rotation rate of Venus leads to a slow build-up of the observation coverage of the planet during the 6 Venus sideral days (~4 E...

May 18, 2023 · EnVision is required to be launched with Ariane 6, the new generation European launcher, in its dual booster configuration (Ariane 62). The baseline launch period opens end Nov 2031 for about 20 days (subject to final ESA/NASA agreement at Mission Adoption) with back-up launch opportunities every 0.5 years until May 2033.
