【 摘 要 】

Given the diversity of asteroids, it is impossible to consider returning samples from each one• Dust particles are abundant around asteroids• Primary minerals and organic materials can be measured by in situ dust detectorinstruments• These particles can be used to classify the parent body as an ordinary chondrite,basaltic achondrite, or other class of meteorite• Such instruments could provide direct links to known meteorite groups withoutreturning the samples to terrestrial laboratories
