Media advisory: Briefing on new analysis of Stardust samples by LLNL scientists

Who: Scientists Hope Ishii and John Bradley will discuss the research, which will appear in the Jan. 25 issue of the journal, Science. Ishii and Bradley will provide new findings on Stardust samples. What: Cometary interplanetary dust and dust samples from the NASA Stardust mission analyzed by Lawrence Livermore National Laboratory scientists show that Stardust samples from Comet Wild 2 look more like cooked meteorite samples from asteroids than pristine comet samples. This means that cometary dust particles collected in the stratosphere remain the least altered and most cosmically primitive materials available to scientists for study. When: Thursday, January 24, 2008 at 10 a.m. Call in: Teleconference on the new Stardust analysis. Call in information provided on an embargoed basis.
