Carbon XANES (X-ray Absorption Near Edge Spectroscopy) spectra of two carbon-rich interplanetary dust particles (IDPs) and a selected set of carbon standards were measured with a Scanning Transmission X-ray Microscope (STXM) to identify the carbon bonding in IDPs. The XANES spectra of 3 regions of one IDP (L2008 F4) show a notable similarity to the C-XANES spectrum of C(sub)60 (known also as buckminsterfullerene, or buckyballs). Efforts are underway to confirm the presence of C(sub)60 in this IDP using other analytical techniques and to exclude the possibility of contamination. The peak positions in the C-XANES spectrum of the second IDP, L2008 H9, suggest that carbon is present mainly as graphite or poorly-graphitized carbon.
