X-Ray Satellite Mission XMM-Newton
The High Throughput X-ray Spectroscopy Multi-Mirror Mission (XMM)
is the second of four cornerstone projects in the ESA long-term
programme HORIZON 2000 for space science. The satellite observatory,
launched on December 10, 1999, with an Ariane 5 will make possible
a major advance in the field of X-ray astrophysics.
The primary scientific objective of XMM is to perform high throughput
spectroscopy of cosmic X-ray sources over a broad band of energies
ranging from 0.1 keV to 10 keV. The XMM spacecraft payload includes
three highly-nested grazing-incidence mirror modules of type
Wolter I coupled to reflection grating spectrometers and X-ray
charge-coupled device (CCD) cameras with resolving powers ranging
from 10 up to 1000 as well as one small optical/UV telescope.
The picture shows an artist's view of the satellite, 3.8 tonnes in
weight and about 10 m in length, with solar cell panels pulled out.
The entrance openings of the three telescopes can be seen at the right
edge of the picture. The MPE has a main contribution on this mission
(telescope development/test, EPIC-pn camera, and survey science center).
XMM was relabeled to XMM-Newton at the press conference
XMM First Light in Villafranca/Spain on February 9, 2000.
