Summary

Impact ionization mass spectrometers have been flown on board the space vehicles Giotto (instrument PIA), Vega 1 and Vega 2 (instruments PUMA1 and 2). All three instruments obtained a large collection of mass spectra of individual cometary dust particles in the mass range 310−16−310−10 g. Spectra from PUMA2 are still being recovered from data transmission problems, and only results from PUMA1 and PIA are presented. A large fraction of particles (~30%) are dominated by light elements (H, C, O, and N, or “CHON”)~35% of particles can be interpreted as minerals with a compositional range similar to that encountered in carbonaceous chondrites. The remaining 35% appear to be mixtures in varying amounts of these two major components. Statistically significant variations have been observed as a function of time.
