Jan 14, 2015 · How much would it cost to go to Venus? An international collaboration of planetary scientists has just submitted a proposal for ESA to launch a mission to Venus in 2025. They’ve also helped us produce an infographic, inspired by our Rosetta cost breakdown, to put this proposed trip into context.

Jan 26, 2024 · The surface of Venus is a scorching 464°C on average, with a crushing air pressure 92 times bigger than we experience on Earth's surface. This leaves us to wonder: How and when did...
Jun 2, 2021 · NASA is awarding approximately $500 million per mission for development. Each is expected to launch in the 2028-2030 timeframe. The selected missions are: DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging)

One of the major questions about Venus is why, despite being a similar size to Earth and a similar distance from the Sun, is it a hellish localewith a poisonous atmosphere composed mostly of carbon dioxide and surface temperatures that are hot enough to melt lead, rather than a pleasant oasis for life. “Why is Venus, our sibling planet, not our twi...
Working out whether Venus ever had bodies of liquid water on its surface is crucial to understanding why Venus and Earth are different. Astronomers can see hints of past waterin the planet’s atmosphere, but it’s unclear whether this water comes from ancient oceans on the surface that were lost as the planet warmed, or whether water existed only as ...
About 7% of Venus is covered in highland regionsknown as tesserae, plateaus that rise above the surrounding surface. These “might be the equivalent of continents on Earth”, says Byrne. To find out, VERITAS will study the composition of the tesserae, including comparing their content of the volcanic rock basalt with regions at lower elevation. “On E...
Earlier probes have shown that volcanoes are present on Venus, but it’s unclear whether any have been geologically active in the past few thousand years — or whether they are still active today. Both VERITAS and EnVision will help to answer this question by mapping the surface. EnVision’s high-resolution images in particular are expected to reveal ...
Last year, scientists announced that they had detected phosphine — a compound of phosphorus and a possible signature of life — on Venus. How this would have been produced was unclear, but there was a tantalizing possibility that it could have been made by microbial life in the atmosphere. The result has since been called into question, and the pres...
The planet’s mountaintops above 2.6 kilometres look strangely reflective, like those on Earth do, “where you have snow and frost deposited above a certain altitude”, says Wilson. But Venus is much too hot for water to exist, leading scientists to wonder whether the reflective regions might be something else. One possibility is a substance called se...

Jun 2, 2021 · Despite the best efforts of scientists eager to study Earth’s sister world, U.S. efforts to send a dedicated spacecraft to Venus languished—until NASA made a surprising announcement.
Dec 11, 2019 · Though their approaches vary, the group agrees that Venus could tell us something vitally important about our planet: what happened to the superheated climate of our planetary twin, and what does it mean for life on Earth?
