Scientific paper

Results are presented of the analyses of mass spectra of 517 grains collected from the Comet Halley dust, which were performed by the dust-impact mass spectrometers Puma 1,2 on board Vega. The results indicate the presence of H, C, N, O, Na, Mg, Al, Si, S, Ca, Cr, and Fe, distributed among silicates; oxides and hydroxides; carbonates and bicarbonates; sulfates and sulfides; and nitrates, cyanides, and rhodanides. These mineral components form various mixtures with organic matter.
