  • Das Rosat%2dProjektteam
    The ROSAT project team

    The ROSAT project team with its Project Leader, Joachim Trümper (fourth from right), at the Max Planck Institute for Extraterrestrial Physics.

The ROSAT project was an initiative from the Max Planck Institute for Extraterrestrial Physics (Max-Planck-Institut für extraterrestrische Physik; MPE) in Garching in 1975. Researchers from Germany, the United States and the United Kingdom were involved in the mission.

The tasks were distributed amongst the partners as follows:

  • MPE was the scientific project leader (Principal Investigator: Joachim Trümper) and contributed two models of the Position Sensitive Proportional Counter (PSPC), a newly developed X-ray detector.
  • After various studies and technical pre-development, the project was approved by the German Federal Ministry of Research and Technology (Bundesministerium für Forschung und Technologie; BMFT) in 1982. The German Aerospace Research and Development Centre (Deutsche Forschungs- und Versuchsanstalt für Luft- und Raumfahrt; DFVLR) in Cologne, now the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), was responsible for managing the project.
  • An industry consortium under the leadership of Dornier (now EADS Astrium) started building the satellite in Friedrichshafen in 1983. Carl Zeiss, based in Oberkochen, developed the telescope optics.
  • The US space agency, NASA, was responsible for provision of the Delta II rocket and the launch.
  • NASA also provided a second X-ray detector. The High Resolution Imager (HRI) was developed by the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
  • In addition to the X-ray telescope, the satellite also carried a wide-field camera (WFC) to capture images in the extreme ultraviolet regime of the spectrum. It was provided by a British group under the leadership of the University of Leicester.
  • The German Space Operations Center (GSOC) at DLR Oberpfaffenhofen was responsible for operating the satellite after its launch on 1 June 1990. From there, the data was forwarded on to the various data centres:MPE and NASA's Goddard Space Flight Centre for the X-ray telescope and the universities of Leicester and Tübingen for the WFC data.
  • The Astrophysical Institute of Potsdam was involved in archiving and cataloguing the data in the 1990s.
  • After the first mission phase – the all-sky survey – was completed, ROSAT was made available for a global guest observer programme. A total of around 4000 scientists from 26 countries took part in this programme.
