“Now that we’re very sure the planet experienced a volcanic eruption only 30 years ago, this is a small preview for the incredible discoveries VERITAS will make.Vintage Car Kick Panel Speakers 6.5" 250W Pioneer For 55-56 ChevroletĪre you tired of that old broken AM/FM radio in the middle of your dash taking up space? Looking to upgrade your radio without making your interior look like a spaceship? If so, Collectors Auto Supply can help you with that! “Venus is an enigmatic world, and Magellan teased so many possibilities,” said Jennifer Whitten, associate deputy principal investigator of VERITAS and assistant professor of Earth and environmental sciences at Tulane University in New Orleans, in a statement. The new mission will be outfitted with radar to create global 3D maps of Venus and capture details about its surface composition, gravitational field and what unfolded in the planet’s past. Missions such as VERITAS will help scientists gain a better understanding of Venus, just as Magellan did decades ago. Volcanoes act like windows into a planet’s interior, allowing scientists to understand more about what factors influence its ability to be a habitable world. Venus may still be active based on 'pack ice' finding Unless we got incredibly lucky, we now know the frequency is every few months or so, similar to the family of Earth’s big basaltic intraplate volcanoes like Hawaii, the Galapagos Islands, Canary Islands, etc.”Ī 1,100 km-wide, false-color radar view of Lavinia Planitia, one of the lowland regions on Venus where the lithosphere has fragmented into blocks (purple) delineated by belts of tectonic structures (yellow). All options could have fit with existing data. We were pretty certain that Venus is volcanically active, but we didn’t know if eruptions occur every few months, years, once every 10,000 years, or longer. “Finding a change that could be clearly confirmed as real was absolutely a surprise. “This was a needle-in-a-haystack search with no guarantee that the needle exists,” Herrick said. The researchers believe the lava flow that Magellan witnessed in 1991 was similar to what was released by the 2018 Kilauea eruption in Hawaii. New findings a 'complete reversal' in understanding why Earth became hospitable to life and its 'twin' didn't The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. Simulated color is used to enhance small-scale structure. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image.ĭata gaps are filled with Pioneer Venus Orbiter data, or a constant mid-range value. This global view of the surface of Venus is centered at 180 degrees east longitude. Both are similar to Earth’s largest volcanoes, but because they have lower slopes, the two Venusian volcanoes are more spread out, Herrick said. Herrick spotted the changes in images of Atla Regio, a vast highland region home to two of Venus’ largest volcanoes, called Ozza Mons and Maat Mons. “I didn’t really expect to be successful, but after about 200 hours of manually comparing the images of different Magellan orbits, I saw two images of the same region taken eight months apart exhibiting telltale geological changes caused by an eruption.” New NASA spacecraft could survive a hellish descent on Venus During its final kilometers of free-fall descent (artist's impression shown here), the probe will capture spectacular images and chemistry measurements of the deepest atmosphere on Venus for the first time. DAVINCI will send a meter-diameter probe to brave the high temperatures and pressures near Venus' surface to explore the atmosphere from above the clouds to near the surface of a terrain that may have been a past continent.
