Optical, Spectroscopic, and Infrared Remote Imaging System

OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) is the main scientific imaging system on the orbiter of the ESA spacecraft Rosetta. It was built by a consortium led by the German Max Planck Institute for Solar System Research.

OSIRIS was approved as an instrument for the spacecraft in 1996. It was launched in 2004 on Rosetta and was used until that mission concluded with the deactivation of the Rosetta spacecraft on the comet 67/P in September 2016.

The OSIRIS has two camera's with a different field of view, but each is a digital camera using a CCD. Each camera has a resolution of 2048 by 2048 pixels and uses the same type of CCD. The CCD's are supported by two Digital Signal Processors that use solid state memory. The computer used the VIRTUOSO operating system.

OSIRIS is two cameras in one instrument:

It was launched on the Rosetta spacecraft in 2004, and first used in space in May 2004.
