| | The Roentgen Satellite, ROSAT, a Germany/US/UK collaboration, was launched on June 1, 1990 and operated for almost 9 years. The first 6 months of the mission were dedicated to the all sky-survey (using the Position Sensitive Proportional Counter detector), followed by the pointed phase. The survey obtained by ROSAT was the first X-ray and XUV all-sky survey using an imaging telescope with an X-ray sensitivity of about a factor of 1000 better than that of UHURU. During the pointed phase ROSAT made deep observations of a wide variety of objects. Mission Characteristics Lifetime : 1 June 1990 - 12 February 1999 Energy Range : X-ray 0.1 - 2.5 keV , EUV 62-206 eV Special Feature : All sky-survey in the soft X-ray band Payload : An X-ray telescope used in conjunction with one of the following instruments (0.1-2.5 keV) Position Sensitive Proportional Counter (PSPC) 2 units : detector B, used for the pointed phase, & detector C ,used for the survey FOV 2 ° diameter eff area 240 cm2 at 1 keV energy resolution of deltaE/E=0.43 (E/0.93)-0.5 High Resolution Imager (HRI) FOV 38 ' square ; eff area 80 cm2 at 1 keV ~ 2 arcsec spatial resolution (FWHM) A Wide Field Camera with its own mirror system (62-206 eV) FOV 5 ° diameter Science Highlights: X-ray all-sky survey catalog, more than 150000 objects XUV all-sky survey catalog (479 objects) Source catalogs from the pointed phase (PSPC and HRI) containing ~ 100000 serendipitous sources Detailed morphology of supernova remnants and clusters of galaxies.
