ROSAT Guest Observer Facility

The ROSAT Mission
(1990-1999)

ROSAT, the Röntgen Satellite, was an X-ray observatory developed through a cooperative program between Germany, the United States, and the United Kingdom. The satellite was proposed by the Max-Planck-Institut für extraterrestrische Physik (MPE) and designed, built and operated in Germany. It was launched by the United States on June 1, 1990. The mission ended after almost nine years, on February 12, 1999.

The U.S. ROSAT Guest Observer Facility (GOF), located at NASA's Goddard Space Flight Center in Greenbelt, Maryland, was part of the Office of Guest Investigator Programs (OGIP) (now called the HEASARC Office) in the Astrophysics Science Division (ASD).

In conjunction with the ROSAT GOF at GSFC, there was also a ROSAT Science Data Center at SAO in Cambridge, Massachusetts.
