What’s on your desktop this week? Mine has an image of the dark side of the Earth:
This image was taken by the Rosetta space probe as it performed its third and final swingby of Earth last month. The data gathered during this flight may help explain the Flyby Anomaly. The Rosetta will next fly to the comet Churyumov-Gerasimenko, where it will deploy a lander. It will arrive in May of 2014.
