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.[1] 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.[2][1]
The OSIRIS has two cameras with different fields of view, but each is a digital camera using a Charge-coupled device (CCD).[1] Each camera has a resolution of 2048 by 2048 pixels and uses the same type of CCD.[1] The CCD's are supported by two Digital Signal Processors that use solid state memory.[1] The computer used the VIRTUOSO operating system.[1]
OSIRIS is two cameras in one instrument:[1]
- Narrow angle camera with a field of view of 2.4 by 2.4 degrees
- Wide angle camera 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.[1] 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.[3]
