Cassini entdeckt interstellaren Staub am Saturn

Universität Stuttgart an einmaligen Messungen mit neuartigem Staubsensor beteiligt

(PresseBox) (Stuttgart, )
Die NASA Raumsonde Cassini hat eine schwache, aber dennoch deutliche Signatur des ins Sonnensystem einfallenden interstellaren Staubs aufgespürt. Zum Einsatz kam dabei ein fortschrittlicher Staubsensor, der von der Universität Stuttgart betrieben wird.

Unser Sonnensystem bewegt sich mit 90.000 km/h durch eine Wolke aus interstellarem Gas und Staub, so dass die Mikropartikel aus einer definierten Richtung in unser Sonnensystem eindringen. Interstellare Staubteilchen im Sonnensystem wurden erstmalig von der Ulysses-Mission in den 1990er-Jahren zwischen Mars und Jupiter entdeckt.

Cassini erforscht das Saturnsystem mit seinen Ringen und Monden seit zwölf Jahren. In dieser Zeit wurden Millionen von kleinen eisreichen Staubteilchen mit dem Staubsensor
