This picture of the Moon was taken by Rosetta’s navigation camera (NAVCAM) right after the comet chaser’s closest approach to our planet. The picture was taken at 00:10 CET on 14 November, as Rosetta’s second Earth swing-by concluded, while the spacecraft was flying at a height of about 6250 km from the surface.

First OSIRIS image acquired during Earth Swing-by No. 3 (2009).

The image shows the Moon as seen through the OSIRIS WAC (wide-angle camera) using the WAC O1 filter from a distance of 4.3 million kilometres at 8/11 03:10 UTC. Rosetta is flying towards the Earth coming in from the night side which is the reason for the very narrow illuminated crescent.

During the swing-by, the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS)on board Rosetta observed Earth’s night-side.

The is a picture taken with the OSIRIS Wide Angle Camera (WAC), showing the same view seen in the OSIRIS Narrow Angle Camera (NAC) image. It is shown in false colour to emphasise city lights seen at night.

This image was acquired on 13 November 2007 at 20:30 CET using the WAC with a red filter.

This is a composite of four images combined to show the illuminated crescent of Earth and the cities of the northern hemisphere. The images were acquired with the OSIRIS Wide Angle Camera (WAC) during Rosetta’s second Earth swing-by on 13 November.

This image showing islands of light created by human habitation was taken with the OSIRIS WAC at 19:45 CET, about 2 hours before the closest approach of the spacecraft to Earth. At the time, Rosetta was about 80 000 km above the Indian Ocean where the local time approached midnight (the angle between Sun, Earth and Rosetta was about 160°). The image was taken with a five-second exposure of the WAC with the red filter.

This image showing Earth’s illuminated crescent was taken with the WAC at 20:05 CET as Rosetta was about 75 000 km from Earth. The crescent seen is around Antarctica. The image is a colour composite combining images obtained at various wavelengths.

This image was taken by Rosetta’s navigation camera (NAVCAM) right after Rosetta’s closest approach to Earth. The picture was taken at 21:54 CET on 13 November, as Rosetta’s second Earth swing-by concluded, while the spacecraft was flying at a height of about 5415 km directly above 44.35° west and 64.49° south.
