Jul 24, 2021 · VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy), like the European Space Agency’s recently announced EnVision mission, will use a set of specially designed...
Jun 2, 2021 · NASA has selected two new missions to Venus, Earth’s nearest planetary neighbor. Part of NASA’s Discovery Program, the missions aim to understand how Venus.
Mar 11, 2022 · Over a few short weeks of June 2021, NASA committed to two new Venus missions, VERITAS and DAVINCI, while the European Space Agency greenlit one called EnVision. All three are expected to...
VERITAS studies the surface and interior of Venus with a powerful new generation of scientific tools – the first NASA mission to return there since the 1990s. The mission was selected for flight in 2021 as part of NASA's Discovery program.

One of the primary things that Dr Kane is interested in is "what makes a planet habitable?" Today, life is not possible on the furnace-like surface of Venus, where temperatures exceed 470 degrees Celsius — that's hot enough to melt lead — created by a runaway greenhouse effect. But scientists such as Dr Kane are trying to work out whether or not Ea...
The DAVINCI+ probe will collect information about temperature, atmospheric pressure and chemistry. "One of the fundamental challenges we have at the moment is that we don't understand the chemistry," Dr Kane said. Venus's atmosphere is primarily made up of carbon dioxide with droplets of sulphuric acid, and is around 90 times thicker than Earth's a...
Studying the atmosphere could also help scientists work out if anything could still – if it ever did – exist in the clouds. Last year, the idea that life could exist in the clouds swirling above Venus was reignited by research that indicated the presence of phosphine in the atmosphere. On Earth, this compound of phosphorus and hydrogen is generally...
What we know about the surface of Venus is patchy. The best data we have was captured by the Magellan mission, which mapped the planet's surface in the 1990s. "But that data is very poor resolution," Dr Kane said. "VERITAS will be able to fix a lot of these problems." Getting better data about the surface of Venus will help scientists understand wh...
We also know very little about what the interior of Venus looks like. Knowing that is important, according to Dr Kane, because we want to know whether Earth and Venus formed the same way. Venus rotates very slowly — in fact only once every 243 Earth days— so we don't know if it has a liquid core like Earth. It doesn't have a moon, so it's very hard...

DAVINCI will study Venus from its clouds down to the planet's surface – the first mission to study Venus using both flybys and a descent probe. It joins the VERITAS mission as the first NASA spacecraft to explore Earth's sister planet Venus since the 1990s.

Jun 2, 2021 · NASA has selected the DAVINCI+ (Deep Atmosphere Venus Investigation of Noble-gases, Chemistry and Imaging +) mission as part of its Discovery program, and it will be the first spacecraft to enter the Venus atmosphere since NASA’s Pioneer Venus in 1978 and USSR’s Vega in 1985.
