Jun 3, 2021 · The U.S. space agency said it was awarding about $500 million each to develop the two missions, dubbed DAVINCI+ (short for Deep Atmosphere Venus Investigation of Noble Gases, Chemistry and...
Jun 8, 2021 · With an emphasis on innovative planetary missions, the program is now heading toward Earth’s closest neighbor: Venus. NASA selected two new missions to study the second planet from the sun.
Jun 3, 2021 · The probes will each cost an estimated US$500 million, and are expected to launch sometime between 2028 and 2030, NASA says. They’ll be the first NASA spacecraft to visit Venus since 1990,...

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...
Jun 2, 2021 · These missions will shed light on how Venus became the inhospitable world it is today, despite the fact that it shares many characteristics with Earth. Two new missions to Venus – DAVINCI+ and...
Jun 2, 2021 · Discovery missions are capped at $500 million, excluding costs for the launch vehicle and mission operations. Both new Venus missions will launch between 2028 and 2030 and will carry...
