In 1999, US space agency NASA launched the Stardust spaceship with what seemed then to be extraordinary aims. The first task of the mission was to take pictures of a comet, before diving into its tail to collect samples of comet dust. The second was to collect any other dust it could; perhaps some that had its origin outside the solar system.
