Space-based dust characterization using impact ionization mass spectrometry is a proven technique for the compositional analysis of individual cosmic dust grains. Here we investigate the feasibility of determining asteroid compositions via cation mass spectrometric analyses of their dust ejecta clouds during low (7\u20139\u2009km\u2009s\u22121) velocity spacecraft flybys. At these speeds, the dust grain mass spectra are dominated by easily ionized elements and molecular species. Using known bulk mineral volume abundances, we show that it is feasible to discriminate the common meteorite classes of carbonaceous chondrites, ordinary chondrites, and howardite\u2013eucrite\u2013diogenite achondrites, as well as their subtypes, relying solely on the detection of elements with ionization efficiencies of \u2264700 or \u2264800\u2009kJ\u2009mol\u22121, applicable to low (~7\u2009km\u2009s\u22121) and intermediate (~9\u2009km\u2009s\u22121) flyby speed scenarios, respectively. Including the detection of water ion groups enables greater discrimination between certain meteorite types, and flyby speeds \u226510\u2009km\u2009s\u22121 enhance the diagnostic capabilities of this technique still further. Although additional terrestrial calibration is required, this technique may allow more unequivocal asteroid-meteorite connections to be determined by spacecraft flybys, emphasizing the utility of dust instruments on future asteroid missions.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lisa Maria Eckart, Jon K.
