Stardust@home is a citizen science project that encourages volunteers to search images for tiny interstellar dust impacts. The project began providing data for analysis on August 1, 2006. From February to May 2000 and from August to December 2002, the Stardust spacecraft exposed its "Stardust Interstellar Dust Collector" (SIDC), a set of aerogel blocks about 0.1 m² (1 ft²) in total size, to interstellar dust. The collector media consist of 130 blocks of 1 and 3 cm thick silica-based aerogel mounted in aluminum cells.
