New NASA Missions DAVINCI and VERITAS Set to Decipher Venus's Atmosphere and History. Dr. David Grinspoon (Planetary Science Institute) and David Livingston (The Space Show) describe the upcoming NASA missions to Venus: DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS. DAVINCI will be the first entry probe with modern instruments since 1979, descending through the atmosphere to sample gases and measure temperature and pressure, also capturing descent photographs. A core scientific goal is obtaining a precise measurement of the deuterium-to-hydrogen ratio and noble gas abundances to better reconstruct the history of water loss and the atmosphere. VERITAS, an orbiter, will use radar and infrared mapping to look for signs of active volcanism and geological evidence of ancient shorelines on the surface. These missions aim to collect detailed data that will allow scientists to walk backward through time and understand how Venus transitioned into its current extremely hot state.
