Abstract: The Dust Flux Monitor Instrument (DFMI) made direct measurements of the dust environment in the mass range 10−14 < m < 10−5 kg at comet 81P/Wild 2 during the Stardust flyby on 2 January 2004. We describe the techniques for derivation of the particle mass distribution, including updated calibration for the acoustic subsystem. The dust coma is characterized by “swarms” and “bursts” of particles with large variations of flux on small spatial scales, which may be explained by jets and fragmentation. The mass of th…
