The Japan Aerospace Exploration Agency sent this unmanned spacecraft to near-Earth asteroid, 25143 Itokawa. Hayabusa succeeded in collecting a sample of material and bringing it back to Earth for further study.

Collect a surface sample of material from the small (550 × 180 meter) asteroid, 25143 Itokawa, and return the sample to Earth. Record detailed studies of the asteroid’s shape, spin, topography, color, composition, density, brightness, interior, and history.

Hayabusa initially surveyed the asteroid’s surface and mapped it from a distance of about 20 km. The craft made two landings in November 2005. This marked the first controlled landing on an asteroid and the first ascent from any other solar system body except the Moon. On April 25, 2007, Hayabusa started its return to Earth.
Hayabusa returned to Earth on June 13, 2010, and the capsule was recovered. Scientists have confirmed that minute particles are in the sample container. Scientists will study these samples for many years to determine the processes of asteroid formation.
