Spurensicherung nach Asteroidencrash

Forscher nutzen einzigartige Perspektive der Rosetta-Sonde, um kosmische Kollision exakt zu datieren

(PresseBox) (München, )
Zwei Asteroiden sind in der ersten Februarhälfte 2009 jenseits der Umlaufbahn des Mars aufeinander geprallt. Zu diesem Schluss kommen Wissenschaftler des Max-Planck-Instituts für Sonnensystemforschung. Die Forscher werteten Daten des Kamerasystems an Bord der europäischen Raumsonde Rosetta aus. Deren einzigartiger Blickwinkel sowie aufwendige Computersimulationen ermöglichten es, den Aufprall exakt zu rekonstruieren. Eine Kollision zweier Asteroiden, die sich vor so kurzer Zeit ereignet hat, war bisher unbekannt. (Nature, 14. Oktober 2010).

Einige Millionen große und kleine Gesteinsbrocken bevölkern den Asteroidengürtel, die Region zwischen den Umlaufbahnen der Planeten Mars und Jupiter.
