Last Update: 06 September 2013, ESA Science & Technology It was launched in 2004 on ''Rosetta'' and was used until that mission concluded with the deactivation of the ''Rosetta'' spacecraft in September 2016. The OSIRIS had two cameras, each with a different

field of view The field of view (FoV) is the extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors it is a solid angle through which a detector is sensitive to electromagnetic radiation. Human ...

(CCD). Each camera had the same type of CCD with a resolution of 2048 by 2048 pixels. The CCDs were supported by two digital signal processors that use solid-state memory. The computer used the VIRTUOSO operating system. The fields of view were: *Narrow angle, with a field of view of 2.4 by 2.4 degrees *Wide angle, with a field of view of 12 by 12 degrees It was launched on the ''Rosetta'' spacecraft in 2004, and first used in space in May 2004. In total, the OSIRIS cameras took 98,219 images during the entire mission, 76,308 of those at the comet. It operated for 22,176 hours.
