Carbon delivered to the Earth by interplanetary dust particles may have been an important source of pre-biotic organic matter (Anders, 1989). Interplanetary dust is shown to deliver an order-of-magnitude higher surface concentration of carbon onto Mars than onto Earth, suggesting interplanetary dust may be an important source of carbon on Mars as well.

小行星和彗星向火星早期表面输送有机物质。

行星际尘埃颗粒向地球输送的碳可能是益生元有机物的重要来源（Anders，1989）。研究表明，行星际尘埃向火星传递的碳表面浓度要比地球上高一个数量级，这表明行星际尘埃可能也是火星上重要的碳源。
