Dawn Spacecraft The Begin Final Science Orbit Today
2012-06-15 04:41:30

After successfully completing nearly five months scrutinizing the giant asteroid Vesta at its lowest orbit altitude, NASA's Dawn spacecraft will begin its final major science data-gathering phase at Vesta on June 15, at an average altitude of 420 miles (680 kilometers) above the surface. Over the past six weeks, Dawn has been gently spiraling up from its lowest orbit - 130 miles, or 210 kilometers, above the surface - to the final planned science orbit, known as high-altitude mapping orbit...

Vesta's Coat Of Many Colors
2012-06-07 09:05:24

[ Watch the Video ] A new video from NASA's Dawn mission reveals the dappled, variegated surface of the giant asteroid Vesta. The animation drapes high-resolution false color images over a 3-D model of the Vesta terrain constructed from Dawn's observations. This visualization enables a detailed view of the variation in the material properties of Vesta in the context of its topography. The colors were chosen to highlight differences in surface composition that are too subtle for the...

[ 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
2012-04-26 03:59:38

[ 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...
