We propose a joint Chandra ACIS-I and XMM-Newton EPIC/pn observing program todiscover the still unknown population of the star-forming region NGC7000/IC5070,at 600 pc. Recent Spitzer data have shown this region to host 2000 or moreYoung Stellar Objects of Classes 0 to II, but missed Class III stars, whichare expected to be numerous as well. The requested combination of high-spatialresolution ACIS data (3 pointings, total exposure: 144 ks), and wider-fieldEPIC data (3 pointings, total exposure: 73.5 ks) optimizes coverage of bothclustered and diffuse YSO populations. These data will permit studies of thestar formation history, early cluster evolution, mass spectrum and segregation,with unprecedented accuracy for this rich region.

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.
