Ejecta fragments from the nearby Vela supernova remnant provide a uniqueopportunity to examine supernova ejecta as they shock and finally merge into theinterstellar medium (ISM). Fragment D is the largest and brightest suchfeature. We propose to map the distribution of the enriched material using fourpointings covering the adjacent bow shock, the tail (including a peculiarspurshaped feature) and the adjacent SNR rim. The rim includes portions of abright irregular ring which may be part of the transient exit wound producedby the interaction of the fragment with the shell. In combination with theexisting pointing, these data will provide a much more complete picture of theinteraction of an ejecta fragment with the SNR shell and the surrounding ISM.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
