The Vela Supernova Remnant (SNR) is notable for a number of protrusions extending well beyond its rim, and "Fragment D" is the brightest and largest such feature. The brightest part of Fragment D has been found to be strongly enriched in O, Ne, and Mg (Katsuda et al. 2005). We have now observed a number of adjacent pointings including the very bright and soft Vela rim to the west, and the peculiar "spur"-like feature between the bright Fragment D head and the bright Vela rim. We recently obtained data for a pointing adjacent to the Fragment D head and the spur. In combination, these data provide XMM-Newton coverage of a significant portion of Fragment D, including its trailing wake across the Vela SNR rim. We report on analyses of the imaging data and morphology, and spectral analyses of the enhanced abundances.
