davinci

DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) is a planned mission for an orbiter and atmospheric probe to the planet Venus. Together with the separate VERITAS mission, which will also study Venus, it was selected by NASA on 2 June 2021 to be part of their Discovery Program. Its acronym is inspired by Leonardo da Vinci in honor of his scientific innovations, aerial sketches and constructions.
DAVINCI will send both an orbiter and a descent probe to Venus. The orbiter will image Venus in multiple wavelengths from above, while the descent probe will study the chemical composition of Venus's atmosphere and take photographs during descent. The DAVINCI probe will travel through the Venusian atmosphere, sampling the atmosphere, and returning measurements down to the surface. These measurements are important to understanding the origin of the atmosphere, how it has evolved, and how and why it is different from the atmosphere of Earth and Mars. The measurements taken by DAVINCI will investigate the possible history of water on Venus and the chemical processes at work in the unexplored lower atmosphere. Before it reaches the surface, the DAVINCI probe will capture high-resolution images of the planet's ridged terrain ("tesserae"), returning the first images of the planet's surface since the Soviet Venera 14 lander in 1982. It will also collect data for studying the planet's origin, and its tectonic and weathering history.
