Venus missions next as NASA seeks info on “Lost Habitable” world

NASA’s Discovery Program will seek out information about our nearest space neighbor Venus in a series of two new missions. The missions are expected to launch inside the 2028 – 2030 timeframe, and both will be awarded $500 million for mission development. The missions DAVINCI+ and VERITAS were selected from the final set of four missions which were in turn part of the original NASA Discovery 2019 competition.


DAVINCI+ stands for Deep Atmosphere Venus Investigation of Noble gasses, Chemistry, and Imaging. This mission will work with James Garvin of Goddard Space Flight Center in Greenbelt, Maryland, as principal investigator. The Goddard Space Flight Center will provide project management.

This mission aims to measure the composition of Venus’ atmosphere. This would be the first U.S.-let mission to Venus’ atmosphere since the year 1978.

This mission will include a “descent sphere” that’ll aim to “plunge through the planet’s thick atmosphere, making precise measurements of noble gasses and other elements to understand why Venus’ atmosphere is a runaway hothouse compared to Earth’s.”

This mission’s intent is also to deliver the first high resolution pictures of tesserae on Venus. It’s suggested by the NASA brief that these images could show if/how Venus has plate tectonics, and whether Venus’ tesserae are comparable to Earth’s continents.

ALSO: DAVINCI+ will also host the Compact Ultraviolet to Visible Imaging Spectrometer (CUVIS) built by Goddard. Using CUVIS, the mission will work with “a new instrument based on freeform optics” to make high resolution measurements of ultraviolet light from Venus.


VERITAS stands for Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy. This mission will have Suzanne Smrekar of NASA’s Jet Propulsion Laboratory in Southern California, as principal investigator. This mission will involve the NASA Jet Propulsion Laboratory, the German Aerospace Center, the Italian Space Agency, and France’s Centre National d’Etudes Spatiales.

This mission will aim to map the surface of the planet Venus. With a synthetic aperture radar, VERITAS will “chart surface elevations over nearly the entire planet.” With this data, NASA will be able to create 3D reconstructions of Venus’ topography.

The German Aerospace Center will provide the infrared mapper for the mission. The Italian Space Agency and the Centre National d’Etudes Spatiales, France, will contribute to the radar and “other parts of the mission.” The Jet Propulsion Laboratory will provide project management.

ALSO: VERITAS will host the Deep Space Atomic Clock-2. This is a tool built by the JPL, funded by NASA’s Space Technology Mission Directorate. This tool generates an ultra-precise clock signal which NASA suggests will “ultimately help enable autonomous spacecraft maneuvers and enhance radio science observations.”
