Genesis

Genesis was a 2001-2004 NASA space mission that captured solar wind particles at Earth-Sun L1, and returned them in a return capsule to Earth. The return had problems, a parachute failing to deploy but some sample was recovered. The spacecraft, which carried the return capsule back from L1, was later put in a heliocentric (i.e., solar) orbit where it remains. The spacecraft's instruments were for the selection and capture of the solar wind particles of interest.
