Synchrotron X-ray absorption fluorescence spectromicroscopy is an essential tool for characterization of heterogeneous (and often very small) extraterrestrial materials. A NASA-funded research program utilizes the TES (8-BM) and XFM (4-BM) to study composition and chemistry of extraterrestrial materials, especially focusing on return-mission samples. Of particular interest are Phosphorus and Sulfur compounds that may be either a) organic evidence of life, or b) precursors or critical raw materials for development of life, on early Earth or elsewhere. Initial samples include meteorites, interplanetary dust particles, and Lunar materials. Current sample-return missions (NASA OSIRIS REx and Japan's Hayabusa2) will retrieve material from distant asteroids in a few years. Future missions will return samples from Mars.
