The Vela Supernova Remnant (SNR) is notable for a number of protrusions extending well beyond the rim. "Fragment D" is the brightest and largest such feature, and it has been found to be strongly enriched in O, Ne, and Mg (Katsuda et al. 2005). The enhanced abundances imply that the feature is indeed a fragment of ejecta from the explosion, but its survival to such a large distance and late time is not well understood. In order to better understand these features, we proposed to observe more of the "Fragment D" region using XMM-Newton. We have recently obtained data for the first of the approved observations, which covers the adjacent bright rim of the supernova remnant. We will report on preliminary analyses of the imaging and spectral data, including the plasma physical conditions and the abundances.
