Description GT- In the ROSAT all-sky survey X-ray emitting protrusions outside the boundary of the Vela SNR have been discovered. They appear to be fragments of the progenitor star and they should be enriched in heay elements, which has been confirmed by ASCA observations but limited by statistics. With XMM we will take spatially resolved spectra of the fragments to clarify the elemental enhancement and the spatial distribution resulting from the mixing with ISM matter. In the southeastern part of the Vela SNR a new young SNR at a short distance has been discovered with ROSAT and GRO, which emits 44-Ti; according to ASCA observations the source appears to emit just spectra of the power-law type. It is essential to search for emission lines and determine the precise shape of the continuum.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
