However, the velocity and molecular  composition of primary minerals, hydrated silicates, and organic  materials can be determined by in&nbsp;situ dust detector instruments. Such  instruments could sample the cloud of micrometer\u2010scale particles shed by  asteroids to provide direct links to known meteorite groups without  returning the samples to terrestrial laboratories. We extend models of  the measured lunar dust cloud from LADEE to show that the abundance of  detectable impact\u2010generated microsamples around asteroids is a function  of the parent body radius, heliocentric distance, flyby distance, and  speed. We use Monte Carlo modeling to show that several tens to hundreds  of particles, if randomly ejected and detected during a flyby, would be  a sufficient number to classify the parent body as an ordinary  chondrite, basaltic achondrite, or other class of meteorite.  Encountering and measuring microsamples shed from near\u2010Earth and Main  Belt asteroids, coupled with complementary imaging and multispectral  measurements, could accomplish a thorough characterization of small,  airless bodies. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>B.
