The DAVINCI+ (Deep Atmosphere of Venus Investigation of Noble gases, Chemistry, and Imaging Plus) mission involves a flyby/orbiter and an in-situ atmospheric probe to study Venus. The science objectives of the mission are to understand the origin and evolution of the Venus atmosphere, how and why is Venus different from Earth and Mars, if there was an early ocean on Venus, the rate of volcanic activity, and the nature, origin, and history of the tesserae.

The mission comprises a carrier bus, and orbital module, and a descent probe. The descent probe is a spherical module initially housed in a conical heat shield, and then is released to drop to the surface. It is equipped with a quadrupole mass spectrometer (the Venus Mass Spectrometer, VMS), a tunable laser spectrometer, a meteorological instrument (Venus Atmospheric Structure Investigation, VASI) and a descent imaging system (Venus Descent Imager, VenDI). The orbiter has a multiband (IR-Visible-UV) camera system (Venus Imaging System from Orbit for Reconnaissance, VISOR).

The mission is scheduled to launch some time in 2029/2030 into a type-1 trajectory Earth-Venus transfer orbit. After 6 months it will make a Venus flyby, followed by a second flyby about 9 months later. The next Venus approach will take place about 7 months after that. DAVINCI+ will release the atmospheric probe about 2 days before reaching Venus. The probe will enter the atmosphere and descend by parachute over a period of about 1 hour, transmitting atmospheric data The orbiter bus will fly by and 7 months later will returrn to Venus and go onto orbit, from which it will conduct orbital science for at least 6 months.
