Katlenburg-Lindau – scientists is a look at previously hidden scenic beauty of the asteroid Vesta succeeded in the meantime as a protoplanet – is considered – ie a planet that is stuck as it were in an early stage of its development. The NASA probe “Dawn” had reached Vesta in July 2011 and orbits until August 2012. Scientists at the Max Planck Institute for Solar System Research (MPS) have now re-evaluated the data “Dawn”.
the MPS scientists managed to suppress aberrations largely. In addition, the calibration of the camera was so refined that even the finest brightness changes are displayed. At a resolution of 60 meters on the surface buried craters on Vesta surface were visualized among other things, tremor, also material that has passed through another asteroid Vesta. Geologically Vesta is more varied than any other so far investigated minor planet, says MPS researcher Andreas Nathues.
“No artist could paint something so”
Impressed showed the MPS researchers mainly from the aesthetics of the color-coded images, in which the different colors stand for different materials on the surface of Vesta. This presentation was made possible by the seven color filter of the camera system on board the spacecraft. “No artist could paint such a thing,” said Martin Hoffmann, a scientific member of the camera team. “This creates just nature.”
Without color coding is presented Vesta, however, rather unremarkable as a grayish, irregularly shaped body with a diameter of about 530 kilometers, covered with a variety of large and small craters.
“Dawn” is, however, the dwarf planet Ceres go. 2015, the probe reach the heavenly bodies, which also draws its orbit around the sun in the asteroid belt between Mars and Jupiter. (Red / APA, derStandard.at, 13, 12, 2013)
