OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) is the main scientific imaging system on the orbiter of the
ESA spacecraft ''
Rosetta'' for its mission to comet
67P/Churyumov–Gerasimenko. 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.

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. Both used a
charge-coupled device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a ...
(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.
