The dust impact detection system (DIDSY) carried by the Giotto spacecraft has measured the density and mass spectrum (in the range 10−20–10−8 kg) of the dust near comet Halley. Profiles of the dust spectrum obtained at a distance of 291,000 km from the Halley nucleus show a complex mass spectrum, depleted in intermediate and small masses. Near closest approach (∼600 km from the nucleus), the dust activity increases dramatically and the spectrum is dominated by larger masses. The cumulative mass… Expand
