Planetary Protection

Planetary Protection

Als Planetary Protection (dt.: Planetarer Schutz) werden in der Raumfahrt alle Maßnahmen bezeichnet, die verhindern, dass terrestrische Lebensformen, wie z.B. Mikroorganismen oder Biomoleküle, mit Raumfahrtmissionen andere Planeten, Monde, Asteroiden und Kometen erreichen und kontaminieren. [1][2] Auch bei Proben-Rückhol-Missionen sollte gewährleistet werden, dass möglicherweise existierende extraterrestrische Lebensformen nicht unbeabsichtigt die Erde erreichen und in die Biosphäre gelangen. [3][4]

Es wird zwischen Vorwärts-Kontamination (engl. Forward-contamination) und Rückwärts-Kontamination (Reverse/back-contamination) unterschieden.[5]
