The Stardust mission, which ended in success on January 15, 2006 after a tour lasting seven years in space, brought back to the Earth the first samples of material taken from the dust coma of comet Wild-2. This comet formed in the Kuiper Belt 4.5 Ga ago. Its orbit far from the Sun helped limit its alteration during its journey and consquently its composition must have been substantially unaltered since its birth.
