PMID: 18218892
Science. 2008 Jan 25;319(5862):447-50. doi: 10.1126/science.1150683.

The Stardust mission returned the first sample of a known outer solar system body, comet 81P/Wild 2, to Earth. The sample was expected to resemble chondritic porous interplanetary dust particles because many, and possibly all, such particles are derived...
