May 22, 2023 · NASA's DAVINCI (Deep Atmosphere Venus Investigations of Noble gases, Chemistry, and Imaging) mission will study Venus from above its clouds down to its surface, investigating how the planet and its dense atmosphere formed and evolved over the past 4.5 billion years.

Nov 9, 2017 · How did Venus become a sulfurous inferno, while Earth evolved to become the only known world with life? Although not currently habitable, Venus lies within the Sun’s "Goldilocks zone," and may have been habitable before Earth.
Jun 2, 2022 · In a recently published paper, NASA scientists and engineers give new details about the agency’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031.
Jun 29, 2021 · These scientists spent decades pushing NASA to go back to Venus. Now they’re on a hot streak. Our next-door planet is similar to Earth in size and composition, but extreme conditions made...

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...

Oct 17, 2024 · With three forthcoming missions to Venus — NASA’s DAVINCI and VERITAS, plus ESA’s (European Space Agency) Envision — space data archive staff are helping scientists access data from Pioneer Venus, NASA’s last mission to drop probes into Venus’ atmosphere in 1978.
