Earth's true colours
Rosetta performed its second Earth gravity assist manoeuvre on 13 November 2007. After its closest approach to Earth, Rosetta looked back and took a number of images using the OSIRIS narrow-angle camera (NAC). This particular image was acquired 15 November 2007 at 02:30 UT.
The image is a colour composite of the NAC Orange, Green and Blue filters.
At the bottom, the continent of Australia can be seen clearly.
