We propose a 30 ksec observation of the west limb of the Puppis A supernovaremnant to study Ne-rich ejecta. We discovered evidence of enhanced X-ray lineemission from highly ionized Ne in archival ASCA data, but otherwise, Puppis Adoes not yield direct evidence of X-ray emitting ejecta. The good angularresolution and high throughput of XMM-Newton will enable us to isolate the Neejecta from the surrounding interstellar medium and perform spectroscopicstudies to measure the ejecta abundances. This program thus provides a uniqueopportunity to study the X-ray emitting nucleosynthesis products in Puppis A.

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.
