The dark material found on the protoplanet Vesta contains the mineral serpentine - and must therefore be of exogenic origin.
Scientists can now compare features first seen at a distance through a telescope to those seen up-close by an orbiting spacecraft.
Large collisions between asteroids transferred carbonaceous material in the inner solar system.
NASA's space probe Dawn is scheduled to leave asteroid Vesta on Wednesday, September 5th, and head for its next destination, the dwarf planet Ceres.
New results prove that Dawn’s target asteroid Vesta is a relict from an early phase of planetary evolution.
First false-color maps of the asteroid show unique surface variations.
NASA’s Dawn spacecraft is now in its first science-collecting orbit at Vesta.
Neue Bilder des Kamerasystems an Bord der NASA-Raumsonde Dawn geben erste Hinweise auf eine bewegte Vergangenheit.
NASA's Dawn spacecraft has returned the first close-up image after beginning its orbit around the giant asteroid Vesta. On Friday, July 15, Dawn became the first probe to enter orbit around an object in the main asteroid belt between Mars and Jupiter.
On July 15, NASA's Dawn spacecraft will become the first spacecraft to begin a prolonged encounter with the asteroid Vesta.
The targets of the Dawn mission could not be more different: While Vesta once had a hot, molten interior that produced lava flows, Ceres has always been a cold body, under whose surface possibly frozen water can be found. In addition, both bodies allow for a look back into an early phase of our solar system. Both asteroids are among the largest survivors from this early phase of planet formation. more...
Dawn is a NASA mission managed by the Jet Propulaion Laboratory (JPL). Its aim is to visit and study the protoplanet Vesta and the dwarf planet Ceres. The space probe encountered its first destination, the protoplanet Vesta, in July 2011 and accompanied it for more than a year. Currently, Dawn is en route to its second destination. It will presumably reach Ceres in the beginning of 2015. more...
The mission's success crucially depends on the two cameras, Dawn's eyes. The cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research with significant contributions by the Institute for Planetary Research of the German Aerospace Center (DLR) and in coordination with the Institute of Computer and Communication Network Engineering of the Technical University Braunschweig. more...
