Zusammenfassung:The Stardust mission captured thousands of particles from Jupiter-family comet 81P/Wild 2 using aluminum foil and silica aerogel collection media [1]. Most studies of Wild 2 material examine refractory terminal particles >1 μm in diameter which are extracted individually from the ends of tracks produced by the particle’s impact into the aerogel medium. A substantial (>65 %) mass fraction of the impactors is present as fine-grained (i.e.
