XMM – Newton, for “xmm” X-ray Multi-Mirror Mission And “Newton”, according to the famous English scientist, is a space observatory launched on December 10, 1999. This observatory of the European Space Agency makes observationsTo study soft (0.15 to 12 kV, ie 0.1 to 12 nm) Feather properties of , the nature of and observe .
XMM – Newton is on onevery elliptical around the earth, currently, a 17,729 km and a. at the height of 103.405 Km. Orbital parameters change as the mission progresses, but Always maintained at 48 hours.
XMM-Newton completed its 4000th orbit around Earth last night! It has traveled over a billion kilometers and we still have fuel left!

During the night of October 12 to 13, 2021,and words 4,000. IsI revolution around the earth. In , they have traveled over a billion kilometers! This is about 8,000 days of activity with very advanced science, for example, the discovery made in 2006 10mxxcs 2215-1738, 10 billion . Feather of the earth; The first measurement, in February 2013, with its US ally NuSTAR, measured the speed of Supermassive (The One in the Heart of the Galaxy) ); Or, last June, mapping an increase of 12,000, allowing the publication of the first findings of one of the largest surveys ever made using this observatory. supermassive at the center of galaxies and .
And the mission is not over: since 2003, the mission has beenand is currently scheduled to run through the end of 2025, with review expected in 2022.
