We propose to observe the Cygnus Loop to investigate the progenitor starand study its roots. Basedon the ASCA observation, we found that there was a metal rich plasmaleft in the core of the Loop. It must be a fossil of the supernovaexplosion. The relative abundance ratio suggested that the CygnusLoop originated from the 25 Msun star expecting the production of acompact star. The scientific goal of the observation is to study thefossil: what the structure of the fossil is, how it is mixing with theISM, what makes an asymmetry.

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.
