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...
Jun 9, 2021 · 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 will map tropospheric gases below the clouds, and in particular species potentially related to volcanic activity such as CO, OCS, H 2 O (separately from its deuterated isotope, HDO) and SO 2. The lower cloud layers will be investigated by measuring gas and liquid H 2 SO 4 content.
Nov 14, 2024 · EnVision is a European Space Agency (ESA) Venus orbiter, set to launch in the early 2030’s. A medium-class mission, EnVision is designed to study volcanic gases in the atmosphere, atmosphere-surface interactions, surface composition, and the interior structure of Venus, and will return high-resolution radar images of the surface.
