New View of Vesta Mountain From NASA's Dawn Mission

This image of the asteroid Vesta, calculated from a shape model, shows a tilted view of the topography of the south polar region. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/PSI.

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, and the Dawn team's scientists believe features around its base are probably the result of landslides.

The image is online here . It was created from a shape model of Vesta, and shows an oblique perspective view of the topography of the south polar region.

The image resolution is about 300 meters per pixel, and the vertical scale is 1.5 times that of the horizontal scale.

Dawn entered orbit around Vesta in July. Members of the mission team will discuss what the spacecraft has seen so far during a news conference at the Annual Meeting of the Geological Society of America in Minneapolis.

Among other things, they'll share their hypotheses on the origins of Vesta's curious craters.

Following a year at Vesta, the spacecraft will depart in July 2012 for Ceres, where it will arrive in 2015.

Dawn's mission to Vesta and Ceres is managed by the Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena.

Almahata Sitta Meteorites Could Come From Triple Asteroid Mash-Up
Nantes, France (SPX) Oct 10, 2011
Analysis of fragments of the Almahata Sitta meteorite, which landed in Sudan in 2008, has shown that the parent asteroid was probably formed through collisions of three different types of asteroids. The meteorites are of particular interest because they contain material both primitive and evolved types of asteroids. The results will be presented at the EPSC-DPS Joint Meeting 2011 in Nantes ... read more
