Many of the images we have been seeing of Rosetta’s comet – 67P/Churyumov-Gerasimenko, or 67P for short – have been captured with the spacecraft’s NavCam instrument. And while they have been amazingly beautiful in their own right, NavCam isn’t Rosetta’s best camera; that distinction goes to OSIRIS, the Optical, Spectroscopic, and Infrared Remote Imaging System experiment that captures both wide- and narrow-angle high resolution images for scientific study.
Now OSIRIS images of 67P have been few and far between since Rosetta arrived, mostly because the instrument is not run by ESA but rather by the Max Planck Institute for Solar System Research in Germany and a rather large international consortium of research groups, and they have first access to the data and decide when images will become publicly…
