In November, Rosetta will deploy a small robotic lander, Philae, which will steer itself onto the comet's surface before sending back images and data on the object's composition.
Over the next two weeks it will remain the same distance from the comet, before edging closer until it settles just 18.6 miles (30 km) above the surface.
A primary initial goal will be to search for a suitable landing site for Philae, using Rosetta's Osiris (Optical, Spectroscopic, and Infrared Remote Imaging System) twin cameras.
