In 2005, 25143 Itokawa became the first asteroid from which samples were captured and brought to Earth for analysis. The Japanese spacecraft Hayabusa (Japanese for falcon) touched down twice on the asteroid and collected a small amount of dust despite the failure of the mechanism designed for the purpose. It delivered the sample to Earth on 13 June 2010.
