![]() ![]() 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. ![]()
