Dawn Provides New 3D Views Of Asteroid Vest
2011-12-02 10:31:47

[ Watch the Video ] Glide over the giant asteroid Vesta with NASA's Dawn spacecraft in a new 3-D video.  Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements. The new video is best viewed with red-blue glasses, and incorporates images from Dawn's framing camera from July to August 2011. It was created by Dawn team member Ralf Jaumann of the German Aerospace Center (DLR). The images...

'Continent Killer' Asteroid On Possible Collision Course With Earth
2011-10-31 04:20:40

On the heels of the return to Earth of a pair of satellites -- NASA's Upper Atmosphere Research Satellite (UARS) and the German-built Röntgensatellit (ROSAT) -- over the past two months comes a report of another object set to collide with our planet. Only this one is a 20 million ton asteroid that is currently heading towards us at 23,000 miles per hour, and could collide with our planet in approximately 25 years, Alex Hannaford of the Telegraph wrote on Sunday. The asteroid...

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,...

  [ 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 will host a news conference on Monday, Aug. 1, at noon EDT, to discuss the Dawn spacecraft's successful orbit insertion around Vesta on July 15 and unveil the first full-frame images from Dawn's framing camera. The news conference will be held in the Von Karman auditorium at NASA's Jet Propulsion Laboratory (JPL), 4800 Oak Grove Dr., Pasadena, Calif. Journalists also may ask questions from participating NASA locations or join by phone. To obtain dial-in information, journalists must...

Dawn took this image over Vesta's northern hemisphere after the spacecraft completed its first passage over the dark side of the giant asteroid. It is northern hemisphere winter on Vesta now, so its north pole is in deep shadow. The Dawn science team is working to determine the significance of the distinct features in this image, which include large grooves or ridges extending for great distances around Vesta. This image was taken by Dawn's framing camera on July 23, from a distance of 3,200...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
