This video [available in three formats: [290 MB .mov, 78 MB HD .mp4, 25 MB SD .mp4] showcases a small sampling of the thousands of images taken by the spacecraft, as well as animations illustrating how MESSENGER moves in orbit and how its orbit has changed during the mission.
The opening sequence is from the approach images from the first flyby in 2008. The first animation to follow (at 0:15) shows MESSENGER in its primary mission 12-hour orbit. The relevance of the November 9, 2011, date is that this was when the MESSENGER team was advised that NASA had approved the proposal for an extended mission, allowing the mission to continue making new observations from March 2012 to March 2013. The animation at 0:22 gives you an idea of the movement and gyrations ("dancing") that the spacecraft undergoes while it performs a schedule packed full of observations that take place over one Earth day. The animation sequence at 0:59 gives you a "top down" view over Mercury's north pole from when MESSENGER first went into orbit until several months into the extended mission. The apparent size of the orbit shrinks from the start of the animation to the end, as shortly into the extended mission, MESSENGER's orbital period was shrunk from 12-hours to 8-hours. The animation sequence at 1:44 shows MESSENGER's "dance" on the first day of the extended mission. The other images and embedded movies can be found in the Gallery section of the MESSENGER website.
