"We are Stardust..."
Joni Mitchell, Woodstock
The scientific importance of these first solid samples from our Galaxy can't be overstated. Interstellar dust and gas were the building blocks of our solar system, the Earth, and all living things, including people. We are truly made of stardust. But we don't know what the typical interstellar dust grain looks like. Not even one contemporary interstellar dust grain has ever been studied in the laboratory! In January 2006, the Stardust spacecraft will return to Earth, for the first time, a few dozen precious contemporary interstellar dust grains. We are extremely excited about the prospect of directly studying contemporary interstellar dust for the first time.
