Genesis Solar Composition: Past, Present, and Future

The Genesis Discovery Mission returned samples of solar matter by exposing ultrapure materials to the solar wind for 27 months in 2002-04. The science objectives are: (I) measure solar isotopic abundances to planetary science precsion requirements. (II) improve knowledge of solar elemental abundances. (III) independently sample the 3 solar wind regimes. Except for the earth return crash, the mission was nominal. We recovered sufficient pieces to make analyses.
