Abstract	GT-The brightest star, optically and in X-rays, in the Orion Nebula is the OVstar theta1 Ori C. It is a member of the Trapezium with mv=5.14. Young hot starsreveal strong stellar winds, as derived from optical/UV line profiles. TheX-rays are thought to come from shocked stellar winds and can be either thermal,nonthermal, or both. With this observation, as part of a more extended programwith O and WR stars, we will obtain a detailed X-ray spectrum to study thenature of this emission. This will give more insight in the origin of the X-raysource and about the location and the chemical composition of the hot gas in thestellar wind. Around theta1 Ori C, the Orion cluster contains hundreds of youngand forming stars. We will study the complete field with the EPICs.

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.
