Organization

As is often the case for the Mandatory scientific programme, ESA has ensured the prime contractorship for the mission and particularly the design of the satellite and the associated operations. The member States have been in charge of the development, instrument supply, and expertise for the in-flight monitoring of the instruments.

CNES contributed to the XMM-Newton mission funding through its obligatory contribution to the ESA programme and directly through the national programme by funding the French participation to the ERMS and EPIC instruments and the XMM-Newton Survey Science Centre (SSC).

The CEA/SAP developed two of the three EPIC cameras, for which the IAS took care of a significant part of the calibration. The CESR (now IRAP) supplied the ERMS.

The CEA/SAP has participated in the in-flight monitoring of EPIC camera performances.

The Strasbourg Observatoire, IRAP and the CEA/SAP, helped by CNES, have brought a major contribution to the SSC.

XMM-Newton is commanded from ESOC in Darmstadt. Data from the instruments are received at ESAC in Madrid, before being transmitted to the SSC for analysis. Over 15,000 observations have already been processed, most of them several times. The latest X source catalogue (3-XMM) published covers 504 square degrees of the sky and registers nearly 250,000 sources.

About 2000 astronomers worldwide use XMM-Newton data.
