Image 1 - Dawn Mission Reveals Ateroid Vesta's Secrets
2012-05-10 13:17:00

[ Watch the Video ] Lee Rannals for RedOrbit.com NASA unleashed a new analysis of the giant asteroid Vesta on Thursday based on data taken by its Dawn spacecraft. Carol Raymond, Dawn deputy principal investigator at NASA´s Jet Propulsion Laboratory, said that Dawn's success has transformed scientists' perspective of Vesta from a fuzzy form, into a planetary body. She said that the asteroid formed within 2 million years after the first solids formed in the solar system....

Dawn Reveals Asteroid Vesta's Secrets

[ Watch the Video ] Findings from NASA's Dawn spacecraft reveal new details about the giant asteroid Vesta, including its varied surface composition, sharp temperature changes and clues to its internal structure. The findings were presented Wednesday at the European Geosciences Union meeting in Vienna, Austria, and will help scientists better understand the early solar system and processes that dominated its formation. Images from Dawn's framing camera and visible and infrared mapping...

Dawn Gets Extra Time To Explore Vesta
2012-04-19 03:30:40

NASA's Dawn mission has received official confirmation that 40 extra days have been added to its exploration of the giant asteroid Vesta, the second most massive object in the main asteroid belt. The mission extension allows Dawn to continue its scientific observations at Vesta until Aug. 26, while still arriving at the dwarf planet Ceres at the same originally scheduled target date in February 2015. "We are leveraging our smooth and successful operations at Vesta to provide for even more...

Dawn Spacecraft Reveals New Details Of Vesta
2012-03-21 13:22:22

NASA said on Wednesday its Dawn spacecraft has revealed new details about the surface of the asteroid Vesta. The space agency said its spacecraft shows new images and data of the diversity of Vesta's surface, revealing unusual geological features. Vesta is one of the brightest objects in the solar system and sits in the main belt between Mars and Jupiter, visible to the naked eye from Earth. Dawn has found that some areas on the asteroid can be nearly twice as bright as others, which...

Since last July, NASA's Dawn spacecraft has been orbiting the asteroid Vesta, and capturing images and other data that are providing surprising results to the delight and amazement of researchers. Dawn's mission is to help reveal the processes and conditions that marked the first few million years – the dawn – of the solar system; and the information the spacecraft has collected about Vesta is changing the way scientists think about the formation of our early universe. Born...

Image 1 - Models Reveal That Vesta Is Likely Cold And Dark Enough For Ice
2012-01-26 05:40:12

Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun. "Near the north and south poles, the conditions appear to be favorable for water ice to exist beneath the surface," says Timothy Stubbs of NASA's Goddard Space Flight Center in...

When NASA's Dawn spacecraft entered orbit around giant asteroid Vesta in July, scientists fully expected the probe to reveal some surprising sights. But no one expected a 13-mile high mountain, two and a half times higher than Mount Everest, to be one of them. The existence of this towering peak could solve a longstanding mystery: How did so many pieces of Vesta end up right here on our own planet? For many years, researchers have been collecting Vesta meteorites from "fall sites"...

Low Altitude Images Of Vesta Returned By Dawn Spacecraft
2011-12-22 04:31:12

NASA's Dawn spacecraft has sent back the first images of the giant asteroid Vesta from its low-altitude mapping orbit. The images, obtained by the framing camera, show the stippled and lumpy surface in detail never seen before, piquing the curiosity of scientists who are studying Vesta for clues about the solar system's early history. At this detailed resolution, the surface shows abundant small craters, and textures such as small grooves and lineaments that are reminiscent of the...
