HAMPTON, Va., Nov. 4, 2011 /PRNewswire-USNewswire/ -- On a bluff overlooking the Atlantic, Grady Koch spent a month watching ocean winds. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) He beamed a laser over the sea, day after day, measuring conditions offshore using an instrument called Doppler Aerosol Wind (DAWN) lidar, which is a type of laser. What Koch learns from the experiment will be used by scientists to advance weather forecasting technology - and also by a...

NASA's Dawn Science Team Presents Early Science Results
2011-10-13 10:19:27

Scientists with NASA's Dawn mission are sharing with other scientists and the public their early information about the southern hemisphere of the giant asteroid Vesta. The findings were presented today at the annual meeting of the Geological Society of America in Minneapolis, Minn. Dawn, which has been orbiting Vesta since mid-July, has found that the asteroid's southern hemisphere boasts one of the largest mountains in the solar system. Other findings show that Vesta's surface, viewed by...

Dawn Captures New View Of Vesta Mountain
2011-10-11 03:56:12

A new image from NASA's Dawn spacecraft shows a mountain three times as high as Mt. Everest, amidst the topography in the south polar region of the giant asteroid Vesta. The peak of Vesta's south pole mountain, seen in the center of the image, rises about 13 miles (22 kilometers) above the average height of the surrounding terrain. Another impressive structure is a large scarp, a cliff with a steep slope, on the right side of this image. The scarp bounds part of the south polar depression,...

Image 1 - Dawn Finds Vesta's Mountains, Rough Surface, And Old-young Dichotomy In Hemispheres

NASA´s Dawn mission, which has been orbiting Vesta since mid-July, has revealed that the asteroid´s southern hemisphere boasts one of the largest mountains in the Solar System. Other results show that Vesta´s surface, viewed at different wavelengths, has striking diversity in its composition particularly around craters.  The surface appears to be much rougher than most asteroids in the main asteroid belt.  Preliminary results from crater age dates indicate that areas...

Dawn Begins New Vesta Mapping Orbit

NASA's Dawn spacecraft has completed a gentle spiral into its new science orbit for an even closer view of the giant asteroid Vesta. Dawn began sending science data on Sept. 29 from this new orbit, known as the high altitude mapping orbit (HAMO). In this orbit, the average distance from the spacecraft to the Vesta surface is 420 miles (680 kilometers), which is four times closer than the previous survey orbit. The spacecraft will operate in the same basic manner as it did in the survey...

  [ Video 1 ] [ Video 2 ] A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta. The data obtained by Dawn's framing camera, used to produce the visualizations, will help scientists determine the processes that formed Vesta's striking features. It will also help Dawn mission fans all over the world visualize this mysterious world, which is the second most massive object in the main asteroid belt. You'll notice in...

NASA's Dawn spacecraft, designed to complete a year-long study of the asteroid Vesta, made its first detailed observations of the surface on Thursday from a distance of 1,700 miles. Dawn will spend the next several weeks taking images from that altitude. Afterward, it will spiral closer to the asteroid to get a better view. The probe was launched in September 2007 and arrived at its destination in July. Dawn is beginning the first of four planned science orbits during the spacecraft's...

NASA's twin lunar probes "“ GRAIL-A and GRAIL-B - completed their final inspections and were weighed one final time at the Astrotech Space Operations facility in Titusville, Fla., on Tuesday. The two Gravity Recovery and Interior Laboratory (GRAIL) spacecraft will orbit the moon in formation to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon. GRAIL's launch period opens Sept. 8, 2011, and extends through...

WASHINGTON, Aug. 1, 2011 /PRNewswire-USNewswire/ -- NASA's Dawn spacecraft, the first ever to orbit an object in the main asteroid belt, is spiraling towards its first of four intensive science orbits. That initial orbit of the rocky world Vesta begins Aug. 11, at an altitude of nearly 1,700 miles (2,700 kilometers) and will provide in-depth analysis of the asteroid. Vesta is the brightest object in the asteroid belt as seen from Earth and is thought to be the source of a large number of...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...
