Abstract

Grains collected from comet 67P/Churyumov-Gerasimenko by the Rosetta mission come from a dusty crust that is predicted to be imminently shed as the comet nears the Sun; the grains are high in sodium and fluffy, not icy, suggesting that they are the precursors of interplanetary dust particles.
